Hello, not sure if this is where I should post, but here goes, I have an ecoair dehumidifier, DD122 Classic Mk5 that is playing up, briefly, it switches itself off after 20 minutes running on all three settings, I have checked the manual, no help, after having searched on t'internet it appears it could be a thermal cutout, anybody on here got any advice, experience, wiring diagram before I consign to the tip and buy another, it seems such a waste as the thing is not long out of warranty, cheers, Andrew

If it is overheating make sure the air filters are clean. If it drains into an internal container these will have some mechanism to detect a full bucket so that would be another point of failure.

Hello, thanks for the response, done all the usual visual checks, I think it is heat related as the thing cuts out completely instead of showing a fault light, my next course is to tack down the heat switch, any clues to its whereabouts gratefully received, cheers, Andrew

Here is a generic fault-finding web page https://www.goodairgeeks.com/dehumidifier-keeps-shutting-off/

Also electric motors often have an inbuilt thermal cutout.

Sounds as if it is the out-of-warranty detector chip, most things I buy seem to have one of those!
