During the past month, I've noticed this. At first I thought it was just because I didn't have it seated correctly......and it started working after a few tries. In the middle of cleaning if I needed to turn it off/back on, it would go off and on fine. So now, I'm using it again to clean and this is what happens. It's like it takes a few tries of on/off before it will actually start up. It is 14 years old and never been serviced but I've taken very good care of maintaining it. But I think it may be time for a trip to the dealer to have it cleaned/checked, even though I don't thin it needs it. The fans looks fine, hepa is fine. Just this weird startup. I think something must be going bad or coming lose. Does anyone know what this could be?

seperator spins freely. Nothing is dirty. Anyway, after it started today, as I'm cleaning it shut itself off mid-cleaning and I swear I could smell something burning, not smoke.....but more like a hot wire or hot metal smell. I guess I'll just take it to dist here in Lex and have them look at it and clean the inside while they have it.

14 years old would make it a Rainbow Gold E2. Just letting you it might be the board. The old circuit boards in most of the Gold E2's around here have been replaced. I should know, I've replaced them for customers. Good news, the board has been perfected and made much smaller with less capacitors, etc. The motor itself will never wear out as there are no carbon brushes. Warning, the board is about $300. All the electricity goes through the board, where it's run through capacitors to turn it to DC current which runs the stators. Except for the AC to the power nozzle. Good news is that once the board is replaced, it shouldn't fail again.

"The motor itself will never wear out as there are no carbon brushes."
Tom, This motor has bearings which wear out/fail in a fairly predicable manner. Rainbow wants you to run these newer machines as much as possible and when the bearings go, have customers simply buy a new vacuum. The bottom bearing is a 6001 and can be had cheaply or simply rebuild it as shown in the video. 2006 Rainbow E2 Gold Teardown Cleaning And Bearing Rebuild Please notice the nearly complete lack of grease in the bottom bearing before refurbishment. About half the time this 2006 E2 was cycled on and off, the motor exhibited an awful screech during wind down. When something spins, there exists friction which generates heat and that causes wear on parts (or lubrication degradation). Bill |

My e2 gold did the same thing after only having it for 5 years. It would run fine on the low speed but only run at about half on the high speed. It too had a burning smell and there was smoke |

I don't know the exact date my Rainbow was manufactured. I bought it NIB summer 2006 without a demo. Anyway, I'm not sure what the issue is with it, but I don't think it has anything to do with bearings. There's never been any change in the sound of it now vs day 1. I do know that screechy sound but luckily I've never had that issue.
Truthfully, I'm a little surprised I'm having any issues at all from a Rainbow that's been babied all these years (babied, but used a lot). But I guess everything needs to be serviced no matter how well it's made. |

" more like a hot wire or hot metal smell"
If what dysonman1 and Rexairfixer said is accurate - that might be what you are smelling is burning solder or the motherboard itself melting. Maybe the solder on the board or a capacitor has failed and its exhibiting this weird behavior. I'd have the circuit board looked at, preferably tested with a multimeter. I just had two of my Acer computer monitors blow up on me that were made in 2005. The capacitor in the power supply on the motherboard went bad is what I am presuming. For 2 months before they totally blew - the monitors would either turn themselves on at random, or they would only turn on if unplugged, waiting 20-30 seconds, then plugging back in. They would also turn on on their own at random or from being plugged back in without even pressing the power button. |

All the problems Rexair had with those first circuit boards forced them to change the board's design as the board had an 8 year warranty. If you look at the board in your machine compared to the replacement board, they are very much different. Interestingly, the new boards are shipped complete with the new board holder, which will not work with your machine. The service man has to very carefully take the board holder apart without destroying it, to put the new smaller board into the old holder. I've done it so many times now, it's a piece of cake. But it sure wasn't the first time I had to do it.
Most people don't baby their machines, which is why we saw the board failure early on. Today, most of the E2 gold models have had their boards replaced and even with hard use (as most people give them) they are not returning for a second circuit board. If they will let you, you might want to actually watch as they service your cleaner. |

Have they gotten back to you about what was wrong? Or did you decide to upgrade to the latest model? |

He said: Is this Mark? I said yes. He said it was the board needed replaced and that normally it's $300, but he said he has absolutely never seen a rainbow as clean as mine. He said since I take such good care of it he would fix it for $225. He was full of questions about how I keep it so clean. He said the fans don't even need cleaning. He said the boards on mine are new and improved that ship with the board holder "will fit my machine". He said it was the previous ones (maybe the early 2 speeds that didn't have foam insulation?) where he said they were a pain to replace because you couldn't use the board holder. He said after this repair I should have no problems.
Anyway - I asked him even though he thought the fans don't need cleaning, if he could clean them anyway (LOL) He said ok no problem. He said it was no nice to see someone respect their machine. |

blows my mind to but in a way I can sort of understand it. I think the demo's may not really touch much on the maintenance of the machine because they are trying to sell one. Even though they state in the manual to clean separator often, change water before getting too dirty....I think maybe most users think "fill with water, vacuum until done, dump the crud...done." In fact,when my grandma had her Rainbow from the 80s and we used it, that's what we did. Filled with water and I remember taking the basin out and dumping the dirt in the ditch and it was thick. I mean, we took care of it but didn't realize the water needed to be changed much more often than we were. God knows what the inside of that thing looked like. We were abusing it without realizing it. That's why I would be paranoid to buy a used one unless you KNOW it's been totally serviced inside and out. They can look so CLEAN outside but be filthy inside.

If you keep yours clean that explains the fans. If you don't clean the seperator the buildup starts there.
The gold 2 speeds didn't have foam batting. The silvers had batting. I have replaced parts on the silver and there's 2 versions. One was pre 2009. The other board was after 2009. I had help fixing them. I must say if you have a rainbow with no build up on the fan that's awesome. You use and maintain it like it is meant to be. Les |

my gold 2 speed actually does have the foam insulation. I remember talking to someone on here a LONG time ago who had a slightly earlier gold 2 speed than mine and there's didn't. Additionally, my gold 2 speed doesn't have the separator wrench/brush. (LOL) Why? From my understanding, there was a brief run where they didn't include them. Mine must have been one of them. Here's a picture of the inside take a while back.

I also got to see the new SRX in person. Such a cool machine.
Anyway - he replaced the controller. I asked him to clean the fans since he had it but he didn't. I think he thought there was no use to clean them. He said they didn't need it. But I figured he could at least clean them since he had it apart. They charged $260 total and there is a 1 year warranty on the new controller...Hopefully it won't be needed. As soon as I got it back I wiped everything down with bleach water (just to be safe) |

Is it working good as new now? The Rainbow SRX was what I really wanted—maybe after I pay off my car—if I financially survive COVID19. |

sounds like it always has from day one. I want the SRX too (LOL). I mean, I even wanted the E3 Black or E2 Black.....But I made it through not getting the black one......and I can make it through not getting the SRX (I think). It's just so hard to justify it when I have a perfectly nice rainbow that will probably outlast me.
I was surprised he didn't give me hell about using a generic HEPA filter. It's so hard to tell the difference I don't think he even noticed. Have you seen the size of the HEPA filters on the SRX?? They are Massive. I wonder what a replacement cost would be for one of those? |

I hope mine will last a long time, as it will be a good long while before I can upgrade. I was surprised the filter on mine is as big as a car cabin filter. The new one looks like it’s twice as big, almost HVAC size. 🤣 |

When I purchased my SRX system a few months back I ask about the life expectancy of the filter and the distributor told me that it’ll last 10 years, 7 if you have pets. Now I’m not sure how true that is but I can justify paying whatever the price is. |

They are huge. I went 5 years before changing my first HEPA that came with mine. Cut into it, and it was barely dirty. Didn't even need changing.
I can't find any of those filter replacements online I was wondering what their pricing was. The current E series HEPA's can be as much as $50. I wouldn't not be surprised if these are close to $100. I also noticed they are a dark color which is odd. |

Glad to know the correct diagnosis was given. I'm sure it runs a lot better now and probably even has stronger suction too. It sounds like the way the board failed, it was not transferring the AC line voltage to the motor properly. Kind of like when you have a cheapo crappy battery in your car and the starter can't get going to turn the engine over I guess?
That's cool he gave you a massive discount when he seen that you were someone that cared for your equipment and this problem was totally the fault of Rainbow and not the user. That does not happen every day, he sounds like a good guy. He probably didn't clean the fan because there was not enough there to be worth it to disturb the rest of the vacuum assembly or he had a lot more services to do and was pressed for time, I don't think he did it just to ignore you. Also Chinese parts have gotten a lot better in quality - a lot of the knockoff Dyson filters, even going over with a magnifying glass you can hardly see the difference both by sight and feel. I have to use china knockoff box filters in my furnace now because the filter media size that it takes (20x20x5) is obsolete, and the manufacturer as well as 2nd party makers quit selling them, which left it open to 3rd party makers to start selling them. |

That’s cool that it fires up quicker. I need to get mine out and go ham. I’ve not used it this week yet. |

If you go to rainvac the part is 32.50.
I'll give you advice. I bought a e2 type 12 rainbow for $30 cleaned it sold for $350. I got an e2 gold for $75. I sold it for $350. I bought a platinum for $75. I sold for $850. I bought 2 silvers for $350 sold one for $600 and one for $500. I still have 2 silvers and two single speed gold's. I'd suggest learning to fix and repair. They do sale for huge profits. Les |

I see the controller. It's basically everything electronic for the vacuum runs through it. I thought it was small board.
I'll tell you what to do. If you know a vacuum dealer or someone who fixes them. You find a used one. If you can't it's a parts machine. I didn't realize it was a $300 part. You can find one I'm not sure of the cost. If you want money out of it this is it. Les |
