Hello!

I have bought this used washer dryer which was said to be working perfectly. The washer function is working well but the drying function is not and the heater doesn't seem to be working.

I opened the machine and started testing the components. I read 40 Ohms at the heater terminals, the thermistor seems to be working because when I disconnect it the machine flashes some lights. But the one shot trip is showing no continuity between the terminals, is this normal? Should this be replaced?

Can you spot anything wrong in the pictures below? In the second picture there is a disconnected hose, is this normal?

Thanks a lot!

One shot is open circuit. On the top of the one shot is a blob of paint stick a pin it it till you here a click. But it will go again if the fan is jammed or the blades under it are full of fluff.
 
Hi rocks,

I forgot to say that I have already tried that but it doesn't click, I tried with a lot of force. I think someone tried to reset it and damaged it, see the picture below. Also, in the last post, do you know if that hose is supposed to be disconnected?

Thanks

Yes. Hose disconnected has had a modification. That's the old heater box and when you change Pcb it needs a wiring change as well. You could try and remove the stat and throw it on the floor to try and reset it

That actually worked, amazing! I noticed that the fan was stuck because of dirt in the bearing, I cleaned it and now works OK, it's drying again.

Thank you very much for the help rocks1!
