My IDCE8450BH had fault code F08. It was an open circuit on the heater coil. I swapped the heater unit complete with the 2 thermal cut out and the thermostat. This gave me a new fault code F04. The thermostat on the new unit was not compatible with the machine. I replaced the thermostat with the thermostat from the original heater unit. Now my IDCE8450BH is running without any faults. Hope this helps.
