Bosch WTW86560GB/14 Heat pump dryer

[ray.t]

Hi,

I got a call to look at this condenser dryer and when I arrived I quickly found out it was a heat pump type. I normally don’t get involved but said I would have a quick look as I was there. It’s showing an error for the filter that’s in the water container and as soon as you turn the dial to select any cycle it sounds like the pump kicks in even before you press the start button. I thought it sounded like something could be blocked so thought I would just have a quick look for blockages and once I got it all apart I found it has a valve on the water container at the top and it’s gone. It’s part number 00638266. Does anyone know if this valve could cause this problem? [h=1][/h]

dont know if hving an open circuit coild will give you the fault code but that solenoid uses water from the draw to clean the evaporator face

have you looked at the evaporator face ?

I did and there was a bit of fluff stuck on it but it didn’t look completely blocked. I will go back and clean that up first and try again.
Thanks Dave.

take a drain pump or a valve coil

connect it to the wires of the faulty coil. we need something so it can see a circuit in case the fault code indicates a faulty coil

Just to update this one, I replaced the valve and it’s working fine again.
