Troubleshooting a Bosch Dishwasher No Heat Problem Using the Schematic and Live Tests

Samurai Appliance Repair Man

In this video for Professional Appliantologist members and Master Samurai Tech Academy students, I show you how to troubleshoot a Bosch dishwasher no-heat problem. No heat problems can manifest in a variety of ways: really long cycle times, a "1" shown on the display at the end of the cycle, or as an error code. Some models will show an error code readout, others may just show the error code as a flashing light. Whichever way, you need to troubleshoot the heating circuit.

As with all electrical problems, you need to use the schematic to pinpoint the open (bad) component. The problem could be the circuit board heating relay, the heater thermostat, the heating element itself, or the pressure switch. I show you how to use the schematic and live voltage tests to pinpoint the exact problem.
