I have removed element no limescale resistance is 24.5 ohms. Resistance of thermostat is about 6.3 kohms at room temperature dropping under 6 kohms when held in hand

Thanks for that. If the rinse and spin cycles are fine but the wash cycles are longer then they should this will be down to a heating fault.

Ive seen this lot on these Bosch washers. Most of the time its the heater that causes this but from the resistance reading you got then the heater will be fine. I also assume you have checked the wiring to the heater aswell?

If thats all ok then the control board will be the fault here. As on these boards there will be a heater relay. Its more then likely that thats failed or burnt out. In this case the control board will need to be replaced and that will cure the fault from there.

So as long as the heater and wires to the heater are fine then the control board is the fault here and will need to be replaced.

As i said we see this fault a lot were the wash cycle takes alot longer then it should to complete and its always down to a heating issue that causes this fault im afraid.
