I have a dead henry!

25 from ebay.

From Henry HVR200A

From Henry HVR200A

Dead as a dodo. Only had a few minutes before having to get back to the office, so I:

Put it's fuse into my Meiele S5, which ran fine, so not the fuse.
Took the top cover off (not motor part) and had a look at the wiring to see if I could work out how to bypass the hi-lo feature. Failed!

Will have a proper look tonight, and sort this thread out to the standard you have all become accustomed to, but if anyone knows how to bypass the hi-lo feature so I can see if Henry really is terminal or not, that would be great.

It's rather clean tbh. Came with it's small tools, floor brush isn't ruined and the body isn't bashed about. Light domestic use I think.

Will try to get some garage time later.

Between you and Ric (on faceache) I think I have enough to get cracking with, hopefully a few minutes after 4pm tonight I should know wether I've wasted 25 or not!

Well, after removing the hi lo Gubbins and making henry single speed...

He works, like new too! As per my facebook post, I think I've narrower it down to the pcb, so will get one of those once ive Confirmed its demise with a multimeter.

However until then the return can continue as normal

With an Eco Henry, I have found no need to use the power boost button, unless there is really heavy soil on carpet or hard floor. I never saw the point of putting the hi lo on either.

Haven't cracked an Autosave open myself yet, but would it be possible to revert one of these back to the earlier style manual hi/lo switch? If the parts fit, and cost roughly the same, I know which I'd prefer.

Post# 263388 , Reply# 8   1/15/2014 at 02:14 (2,834 days old) by beko1987 (Stokenchurch, United Kingdom)        

I think the switch would fit, so if you knew the internal parts you need I'd say an old sdtyle hi lo switch would work.

See if these pictures help you...

Having confirmed with a multimeter that the switch works, I bought a new PCB yesterday, so hopefully that will turn up tomorrow!

Thought I'd better get this thing stripped down then

One stripped Henry! The design hasn't really changed but the build quality has! There's burrs of plastic on the cut edges, random rubber squirted in the front of the motor plate and carbon dust everywhere. Dont remember my 1995 Henry having that much of a messin there!

Can't believe that much dust and fluff accumulate under the metal sole plate on the floor head, I'm tempted to strip some of my floor heads down to see if they are the same. I'm sure the Henry will look good once you've finished!

I do have a steam cleaner, but don't use it on the vacs. It's not that great, all I'd end up doing is chasing dirt around, it is a PITA to set up and I'd burn myself alot!

Quicker under the hot shower with a selection of brushes and a nice strong mix of G-101!

Interesting. You don't show a pic of the old PCB that you removed?

I opened up my 2011 Autosave model, and it appears that the PCB it has -part 208428 has been superceded by the part you show - 208700, but these PCB's are different, in that the components on the old part sit in the actual airpath of the exhaust air, whereas on the new part, 208700, the main components are on the other side, out of the airflow path.

I'm wondering if the carbon dust from the motor exhaust gets over the components of the old type boards and causes them damage, and possible shorting out? just a thought?


This is the old type board - note that the wire connectors are on the back, so that the main parts of the board are facing into the exhaust air flow

Thanks for that pic Beko - your old Henry HVR200A was fitted with the original green autosave board, the 208100. It seems that newer models are also failing by looking on ebay, I saw one manufactured in 2012, which would have the red 208428 board that my 2011 Henry has in it.

This would suggest that either the main transistor/resistor is overheating and burning out due to impeded exhaust airflow, or carbon dust build up is damaging the components on the boards.

The fact that your "service kit" has the components - all except the main transistor/resistor - on the other side of the board - tells me that the carbon dust build up could well be shorting out the tiny circuits on the old board - because, as you know, carbon is a conductor of electricity.

A very bad design flaw indeed, and a potential ticking time bomb for thousands of HVR200A's with the old type of boards.

IT may pay us to remove the bases of the motor housing every so often to clean off the circuit board, which is found built into the edges of the exhaust porting, and its easily seen by removing the 7 screws from the motor unit (henry's head) and lifting the base upwards away from the head with the head remaining upside down.

It would also be useful to know at what point Numatic started fitting the service kit that Beko shows as standard.

I am sure that AlexHoovers94 will take his head to pieces to find out if his 2013 Henry with the removable face has the old 208428 board or the 208700 modified one

Or fix it for 15 pounds, or remove the hi lo completely.

As much as it sucks that its a flawed component, seems silly to write off 100 of vac for an easy fix...

Right, I just took both the Bertie and James apart. The James was bought brand new in July 2013, made in the 23rd week of 2013, has the old style PCB facing the motor. Although, the Bertie, bought brand new in November 2013, made in the 33rd week of 2013, has the new style PCB, facing away from the motor. So Numatic switched to the new style PCB sometime between 23rd week and the 33rd week of 2013. Alex's Henry should have the new style PCB.

That's odd that the James has the green one - whats its (the board's) code number? How many watts is James?


MIne - A yellow henry HVR200A was made week 20 of 2011 and has a red board facing towards the motor.  Code 208428

Beko's - A red henry HVR200A was made week 27 of 2010 and "had" the very old green board facing towards the motor. Code 208100.


BTW they are still selling the old green boards 208100 on Ebay and they seem to be selling in good numbers too!

AFAIC this should have been a product recall or similar as so many Henrys will be affected. Numatic stand to lose a lot of consumer loyalty of this - as I didn't know about it until recently and I don't use my Henry that much, but other people think Henrys are reliable and long lasting - they may be, but the PCB's aren't.

I wonder how many Henry AutoSaves have been thrown on the scrap heap because they develop board failure - even though they have perfectly good motors?

I wonder if Numatic weren't trying to build in obsolescence into their vacs so that they would sell more of them?

Post# 263715 , Reply# 35   1/17/2014 at 15:11 (2,831 days old) by HI-LOswitch98 ()        

I hope not - that Numatic are making machines that fail early so they can sell more of them, they do come with a 2 year guarantee though however most people think they won't need it.

"AFAIC this should have been a product recall or similar as so many Henrys will be affected. Numatic stand to lose a lot of consumer loyalty of this"

I have to say, that's quite a sweeping statement. I didn't see anything which suggested there was an "official" problem, only that there has been a design change which is being assumed was such to solve a problem.

Product recalls only ever happen when something has been found to be unsafe, rather than problematic. As has been established many times, a good deal of Numatic cleaners are purchased for commercial use. The fact that one breaks down will be, in many cases, par for the course and likely considered by whoever is in charge of buying new machinery to be the fault of the cleaning personnel not taking the right care, rather than a problem with the vacuum cleaner.

When I worked at Welcome Break - there were quite a few Henrys that had broken down at our site, and most weren't that old. They ended up buying Karchers instead - so an example of lost trade here for a start off.

I know they have now modified new models, but its taken a while, and what about all the annoyed customers whose Autosave Henrys have failed within a short time - those who threw the receipt away and couldn't claim - or be bothered to claim under the guarantee?

It disappointed me that Numatic has been guilty of putting substandard PCB's in their machines. Its introducing spanners into the works of what was once a very simple one speed, reliable vac, which had very little to fail.

I agree the autosave is more to go wrong. However, a receipt is not required in law, only proof of purchase. If a consumer chooses not to claim for a repair for whatever the reason, that is up to them.

I wonder if we will see more of this though. Numatic, once the cockroach of the vacuum world (will survive even a nuclear apocolypse!, think Nissan Micra for the UK guys!)

Maybe in 10 years Numatic will have gone down in people's opinions too much. When did the PCB first come in? (Not au fait with modern numatics I'm afraid). Let's say 2004. 2004-theoretically mid 2013, that's alot of ticking time bombs out there. Most vacs in shops now I see are the hi/lo ones, switched to hi obviously!

Even for us it may not be great. Hoover enough off ebay dead to fix, then the market gets flooded and the price goes down.

I've got Henry advertised in various places for 75 ono, will be interesting to see what I actually sell it for, and what the value of a 4 year old one is. Bet it's less than some of the old ones go for (single rocker on back etc)

I think you are right about the twin speed models coming out in 2004.


However, it may just be the models with autosave that have the problem boards, as I haven't heard of any problems with the older type of twin speed models - not to say that there haven't been any. This seems to be a new problem only just coming to light on EBay, and Autosave models started in 2009/2010 I think? so they are now just starting to get old enough to start failing in larger numbers.


I saw your henry on Gumtree - I went looking for it:

Is a test the waters price. In reality I'll take 60, but if someone wants to hand me 85 then I'm not going to stop them! Is a more realistic 75 bin with a make offer button though on ebay, and I'm floating it round the forums at 60 plus post.

If I've had no responses to the ads by the middle of next week I'll bang them down to 65 and just wait but hey, we can all try our luck!

As madabouthoovers says, it is the ones which have autosave which seem to go belly-up. These are the ones which power up on a low setting, meaning that the board is regularly in use. The original hi/lo cleaners were manually locked in one position or the other, I expect typically the hi position, therefore the circuit boards were by-passed. Do you recall how many Hoover Turbopower 2-speed cleaners would always work only at one speed across both switch positions? This is because although most consumers would run the cleaner at full power, the switch was easily pressed into the "1" position, particulary if the cleaner was carried around by the main handle and not the carry handle. When the cleaner was plugged in, off it went at low speed, that was of course until the diode burned out and it ran at full power.

I agree that 2004 was the launch of the hi/lo switch. It was originally found on the back of the cleaner as there was a foot switch on top to operate the power. When the foot switch went, both controls were then mounted on the top of the machine.

I think it's a shame that Numatic's reliability record is being damaged by a something so little as a PCB. I really do think it'll cause Numatic problems in the long run, which is a real shame. All those machines made between 2009ish and mid-2013 are prone to failure in a few years, which is not good.

The one big thing with your Gumtree ad is that it contains a video which is headed "Dead Henry with new PCB". That's a big put off, naming it "Dead Henry", as it makes people think its had so much use that the board burnt out. If I was you, I'd remove that video as it could be harming any potential sales, as it also makes it look like the little red light on the Hi switch doesn't work too.


Best of luck otherwise with the sale!

There is a handy table here showing various different dates and models of Numatics, and it confirms that 2004 was the time the twin speeds were launched.

Not until I know how many cleaners are affected and what people are saying about it would I be able to disagree or agree with whether or not it will affect Numatic's reputation.

Beko have spent much time and money recalling fridge-freezers and tumble-dryers which were catching fire, as have Bosch and Hotpoint with dishwashers, for the same reason. And they're doing alright still.

True, and whilst I hope it, in reality wont really hurt numatic, if they fail by their hundreds/thousands around the WORLD now (Their making more of the international nowadays!) surely someone would notice the drop in sales?

Post# 263749 , Reply# 49   1/17/2014 at 17:05 (2,831 days old) by vintagerepairer (England)        

IF that happened, some people may stop buying the cleaners, but like I said, it would depend on the % of cleaners which go faulty against how many were actually sold. The footswitch introduced in 2003 was very problematic and Numatic ditched the design within three years. But never once did I hear anyone talking to me about Numatic cleaners and remembering the dodgy foot switches.

We have three choices here: carry on speculating, or contact Numatic and ask them if there is a problem, or sit it out and wait to see what happens.

The hi-lo switches have no problem - the Henry we have at home which has the hi-lo feature is from 2006 & it is still perfectly fine!

It would be interesting to know the real reason HOW the boards are failing though?

If its because the airflow gets blocked by a full bag or clogged hose, and the board components subsequently overheat?

This overheating would only happen when used on LOW power setting anyway as the board has to step down the power to the motor and this has to be dissipated by heat - which needs a good airflow to remove, or failure could occur.


Its an interesting subject though, as Henrys are usually so reliable that threads like this are rare, and naturally, as collectors, we are interested in any inherent design flaws in various models.

These threads also help owners of broken down Henrys who google Henry HVR200A in the hope that they might find info about whats wrong with their Henry

I think we are over analysing it but hey, its what we do!

I have no idea how hard a life my henry has had. I suspect light domestic. I imagine Henrys in our hands will have a lot less use, and will inherently last longer.

I suppose, what usage would shred carbons quicker, as that seems to be a root cause.

Steve, RE: reply #51.


I think what causes the PCB to fail is carbon dust, it's conductive so if it gets on the PCB it could easily mess it up.

Joe, I said that in reply #18 I thought a possible cause could be carbon dust shorting out the board. But I cant be sure - its only a speculation.

Its a pity Beko doesn't have a PhD in electronics or he could have diagnosed the board failure.

I don't want to use my Henry now in case the board burns out - unless I know the method by which the board failure occurs

In Beko's pic below, what is the name of the component with the ?? against it - this part seems to be the cause of heat staining on the board above it. Could it be this component that is what is burning out?

Ha I don't have a pHd in anything!

My stepdad poked it witha multimeter and confirmed it was dead. Sadly, and I've jsut realised he hasn't poked the new board...

However, he did recall a yarn to me. He works in electronics, has done since the 70's. Apparently, once, some US manufacturer made a power supply for a computer. Worked well abroad, they started selling them here. He had a broken one in for repair, and found that a certain component was only rated to X value. X value was fine in the US, but too low for the UK, which has Y value. 80% of the time, the product will work well, but if the load increases above X value, it breaks and kills the product. A change was made and it was all fixed etc.

Maybe, since these machines now go all over the world, something similar is happening here. Some component on that board cant take the heat/hi-lo switching cycles/constant high power. Of course one would need to browse foreign ebay to see what the failure rate is, but I bet alot of the abroad use is from companies who buy fleets of them.Enough of the fleet dies in a silly amount of time and bam - dropped from the books due to unreliability. So we may never know, as I doubt they go to ebay!

The switch is very simple, and mine was spotless inside. When the switch is flicked, it contacts thecontacts, which send the signal to change power to the pcb. (incase anyone thought it might be the switch)

Happy to post my dead board to someone more knowlegable if wanted! I'm getting quite interested in this!

On that chip, the model id is only very different between the boards. Both made by the same company too.

That chip is my primary concern tbh. On my S5, the thermal fuse is very similar to that, just bigger. That had blown on the solder joints. But the whole module was replaceable (at eye watering cost from miele I assume!) as the chip was supposed to die first (after considerable red light of doom)

Same could be happening here either inadvertantly, or as a failsafe which is proving unreliable, hence the service item note on the new boards bag!

Manchestervacs, are you reading this? Any insight from a professional point of view? Know anyone who gets alot of henries in? Any trends?

I wouldn't worry about it, fitting a new PCB is cheap and easy.


I'm not too sure what that is, but whats funny is, in the Bertie, the PCB if facing away from the motor, but that piece seems to be on the other side facing the motor? I found it odd. I'll get some photos up tomorrow

I agree, as a general issue for us especially, I'd rate it no more tricky than getting a motor out of a 1334! 'Service Item', get some in alongside your belts and bags for the rest of the fleet!

If you skipped the washing, drying, posing for photo's etc you'll be done in 15 minutes! All screws out, lift off the hat and take cord rewind out, lift the next bit up enough to slide the pcb out, swap the wires over and slide it back in. Re-assemble, job done.

Post# 263765 , Reply# 63   1/17/2014 at 18:00 (2,831 days old) by madabouthoovers ()        

That part is still on the side facing the motor as it needs to be in the path of the cooling air from the exhaust duct, which suggests it gets hot in use and even after the board was modified, it remains in the airflow.

It looks like a large transistor - a kind of switching relay.


If the henry has a thermal cutout, this is likely to be built onto or into the motor housing, which I haven't yet had a good gander at. I only opened up my Henry to see what type of board it had in it.

Beko - with an electric screwdriver - turn the head over and remove all 7 screws, then lift up. The top comes off and reveals the board slotted in the ducting. I looked at it last night and its possible to change it in less than 2 minutes.

The big problem is that Joe Public wont know this and assume the motor has gone tits up when henry "just stops". Hence they will throw it out or sell it  on ebay without realising that they could get a "service item" for £20 or so to fix their Henry.

Looking up transistor on Wiki, it seems that the component marked with ?? is indeed a power switching transistor. It has three legs. when a small voltage is applied to the centre leg, it allows a certain current to flow through the other legs. So it effectively controls the resistance of the motor circuit between the Hi and Lo states. When in Lo, the input voltage to the centre leg changes the resistance of the circuit to increase it - and this lowers the current flow to the motor. The transistor then gets hot as its offering higher resistance to the current flow - hence the transistor is fixed to a heat sink, and this is in the airflow.

I wouldn't be surprised if that big black 3 legged component isn't actually a triac. The design may well be chopping the AC waveform to reduce power to the motor as a basic high/low speed controller. They're often used in dimmer light switches and for switching heating elements (I work for a heating company and see Triac's in more products these days).

I've got an older pre Autosave Henry here with the red footswitch and a green side hi-lo switch. If these also had a similar board inside I'd have a look to see if the AC supply is being chopped like I suspect.

Yep, just as I thought. It's a Triac, 12Amp rated.

The circuit board is like a dimmer switch, fixed to a lower setting, chopping the AC waveform to reduce power to the motor. It's either getting too hot (no heatsinking, poor airflow) or like others have suggested, the carbon dust has snookered it.

If it's just that component that's failed and it hasn't killed anything else on the board, the Triac's are sold for about 1.29 + VAT from RS Components, part number 687-0947. If something else on the board has failed too, you might as well shell out the 15 on a re-designed PCB or just bypass the ruddy switch altogether :)

Well then if you want to keep your Eco Henry, I suggest buying a whole bunch of boards!

I was actually going to buy the exact Henry with the exact problem like Sam's one approx 2 months ago which went for £32 I think?

Post# 263952 , Reply# 76   1/18/2014 at 16:31 (2,830 days old) by madabouthoovers ()        

Thanks to MooJuice for his info - hopefully people will be able to find this thread in the future if their Henry suddenly "dies".


I think that with a heavy enough build up of carbon dust all over that circuit board, its bound to have caused a short somewhere, which was why Numatic had the majority of the circuitry turned round to the other side of the board, so that only the Triac faced the carbon dust flow.

Incidentally, there is a carbon filter wrapped round the motor, so maybe washing this out once a year might help reduce the instance of board failure?

My cleaning lady recently uploaded me to facebook. I have four friends in my list. I like it that way. I am finding the internet to be both a treasure trove and a Pandora's box, in similar measures. I laugh at what I read on facebook. 20 years ago people were often 'ex directory' (if you are young and don't know that term, look it up on this wonderful internet) and yet today people cannot wait to spread their business around.

There was a woman who lived on the corner of the street where my parents house was. She was the equivalent of what we know today as the BBC News 24 channel. She is also long dead, yet I cannot help wonder what she would have made of the facebook.

Hi I have a henry and have recently changed for the red one,

Quick question

Before I changed pcb could get no power,just a light on the high low rocker

Now I've changed pcb henry lives again yay !

But no hi low function just one speed LOW

i wired it from wiring diagram

I've told the seller of the pcb but he says it must be the high low rocker switch

I'm just wondering did he send me the wrong wiring diagram for the light up rocker switch?

Interesting read.
My Henry Autosave was dead when I got it a few years ago, only the high/low would show a red light if pushed but the motor wouldn't run.

Found it had a worn out brush, replaced it and off it went, but only ever on high. Works fine, sounds like the triac is shorted in my case, so it's able to run.

What is the best way to bypass the PCB?

I have my dead Henry in bits - worked fine 2 days ago - today the light came on the hi-lo switch when Henry was powered up, but no motor. After sucking my teeth a few seconds and pressing the switch a couple of times, and cycling the power, now all lights are off. Switches test fine with meter, and there is power into the Henry from the plug.

So it looks like PCB. I'm happy to remove it, I only ever run it on high anyway.

I have a brown/blue/black/white into the red PCB. Do I join those, leave hi/lo switch alone, or remove from PCB and connect into hi/lo etc...

Any pointers appreciated.

You want both white motor cables to one side of the main on off switch, then the blue and brown wires from the cord unit to the other side. You may have to have henry apart to the motor to check which cables are which then either strip out the pcb and wires, leave the switch in to stop stuff falling in the hole and hopefully you will win!
