Even if the switch is clicking, and the float arm is moving, that does not mean that the float switch is working.
The water level switch can be tested in two ways.
the first one is jumping the switch, and taking care of not overfilling by manually stopping the cycle. For safety reasons this test must be done by a trained technician.
Other way to test the switch is by reading Ohms with multimeter set at Rx1 on the switch terminal while operating the switch. The switch must be disconnected from rest of wiring first.
If the switch is opening and closing the circuit, then it is good. If there is no continuity, then it is bad and inlet valve will not get powered.
If the float switch is OK, test the door lock switch, and find out if there is any pressure switch to test. Bosch dishwashers have a pressure switch located at the bottom of the appliance, on the drain lines.
If everything is Ok, then a tech will need to read volts at the electronic control board contacts.
Disconnect power before performing any testing or maintenance operation on the appliance.
All tests must be done by a trained technician.
