It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAINto work when it is commanded .If this does not happen then the voltage at these pointsmust be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect. The error indication can be a short in the circuit, check the heater circuit and the pump motor.
Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.
Bauknecht are built by Whirlpool.
F7 on Whirlpool means flow meter failure.
Check water inlet, check the pressure switch, and check the sump filter at the bottom of the dishwasher. To reset try turning on the power and holding the start button and the + and - buttons at the same time.
F7 error indicates a fault with the water flow meter .
Check the sump filter at the bottom of the dishwasher, then close the
door and turn on the power. then hold the start button with the + and -
buttons under the LCD display, until the drain pump starts. This
should then reset the dishwasher.
Function key shorted or stuck button
Replace touch pad or clock assembly (also called the ERC) or attempt to un-stick button
Shorted key sensed for 32 seconds
1. Membrane shorted, or, 2. Display board defectiveIf touch pad is a separate unit then unplug it and see if code comes back. Unplug range before doing so. Once touch pad is disconnected, plug range back in and see if code shows. Wait a few minutes. If no code then replace touch pad. If code does come on while touch pad is disconnected then replace main control. If touch pad and main control are all one part then replace the whole control. Doubt if you would have any luck trying to unstick the bad button as stated above.
I have this problem frequetly - it's an easy one to fix! Just press the programme button which changes the programme setting you want (on my built-in GSX4756 it's the last button on the right) and keep it pressed in until the beeping stops. Then start it again (will probably be on the rinse programme if it's like mine).
