Re: Candy CDC 266 Condenser dryer
The filter light is normally triggered by a thermostat or cut-out failure on the heater but as yours heats (albeit not fully) it throws some doubt on this but I would suspect at least that one of them is cutting out too early or the exhaust thermostat may be the culprit.
A visual check may show up as they can discolour etc at times.
Power off befor checking :zap:
If the heater thermostats are the problem then it’s a whole heater replacement unit only I’m afraid 🙁
