DC25 Post Motor Filter Howl |
[Down to Last] |  |

Just scored a curb find of my first Dyson ball vac. After a thorough clean up, the machine emits a very loud howling sound when the post motor filter (in the ball) is installed. I meticulously cleaned and dried both filters, so I'm wondering if this sound is normal. When powering down the single pitch howl actually briefly turns into a two note chorus for a few seconds.
To reiterate, this strange (and un-characteristic) noise does not happen if I remove just the post motor filter. Is this filter damaged? I have no issue replacing it, but not if that awful howling is normal. The sound of the DC25 emits is a pretty close match to my DC14 (non-ball) when the post motor filter is removed from the ball. Comments and suggestions welcome, Bill

Found the issue...
It is indeed just the post motor filter seal. What happens is that over many years, the seal loses its "springy-ness" and no longer creates a seal with the outer motor housing. My seal isn't cracked or damaged in any way, so this is a wear failure. After Googling, I found this simple solution in pic #2. A piece of string, wedged into the folds of the seal works perfectly! Now my DC25 is quieter than my DC14. All howling gone.

My Dyson ball also makes that strange "farting" noise as it powers down. My doesn't not whistle or whine while its running though thank goodness. May have to give the string trick a try, would certainly be a lot cheaper than buying a new one!. Cameron. | ||

Every dc25 I've ever used or owned (I've had two and hated them) has done that, it's definitely the seal on the filter. I found if you heat the seal with a hair dryer, then try to push it back into shape, then let it cool down, it seems to help. I think the dc25's are pretty poor vacuums to be honest, good suction from the hose but easily clogged, and very poor carpet cleaning.
