My Bosch SHU9922UC dishwasher is stuck in drain cycle. This had happened one time before and after removing the machine and removed the Water level switch housing and the Level switch assembly then reinstalling these components it started working correctly again. I have tried the diagnostics procedure and what is indicated is 2 faults "Heater Fault" and "Water filling fault". There is reason to believe it is not the heater or the fill solenoid. Currently the machine is stuck in drain and the pump will not stop running and fill solenoid does not activate. I believe the failed component is either the Level switch housing or level switch or perhaps the Level switch housing assembly Any help would be appreciated.
