no heat Bosch WVH28420EU, no heat.

Our washing machine stopped heating the water and heating the dry cycle. It does all the cycles, wash and dry but there's no heat at all.

I've bought new heater and thermometer, checked all the wires but still no heat. There is also no error code.

I've read the topic where the solution was loose cables, so triple checked that also.

What can it be?

A washer dryer has separate heating elements for washing and drying. It's highly unlikely they have both failed or for any fault to cause them both to stop working. They are totally separate systems. What makes you think there's no heat - does the wash or drying cycle stick or stop working, or are clothes coming out dirty? What are the symptoms that caused you to look at the machine?

Before when the dry-cycle was running I could feel the heat in the room. Now it's no heat and the wash doesn't get dry after the dry-cycle. I thought it was the same heater for both. Anyway I swapped parts 0306 and 0307.

Any idea?

I've checked now and the water gets warm during cleaning. So it's only the dry-heater that is not working. Any ideas?

The dryer's heating element should be on top of the outer drum.

Ok, after running dry cycle, the clothes get warm, so feels like the heater for the drying part works but the clothes don't get dry. After a drying cycle the clothes are wet but warm.

I've cleaned the pump at the bottom right of the washer.

Hello. On a washer dryer, if the laundry is coming out warm but still wet try this - Laundry comes out of washer dryer hot & steamy
