Hi, I have a Hotpoint Washer/dryer. Washing works well, but drying stops with F13 code after cca. 5 minutes. The ventilator motor makes a buzzing noise. I think it turns slower, then it should, but can’t see any junk, to slow down it, I can rotate the blades easily. The motor of ventilator looks intact. In spite of that it is the reason of overheating? Can someone help me? Update (10/01/2020) Type is FDD 10761

The motor replaced, the error have disappeared, the drying function works like before.

Csaba Katona  F13 for Hotpoint washer dryers is a Dryer temperature sensing fault. So this could be a bad sensor. For now I suggest you start looking at something like this repair
