It rinses and spins as normal, Heater tests out OK, any ideas on what the problem is please? July 20, 2009 at 1:59 pm #292696 MartinParticipant Re: BOSCH WTF2806GB/13 NOT HEATING. Well only 2 options spring to mind, either there’s a break in the heater leads somewhere or the heater relay on the board has given up?

I think you are right Martin, I’m blaming the Heater Relay, have you seen the price of those modules, I don’t think she will have that job done.
