Bosch Error Code F2
Motor problem
Common Causes
- 1Wash motor failure
- 2Motor winding issue
- 3Control board fault
If the circuit breaker trips with F2, the motor winding has a ground fault. Do not reset the breaker repeatedly — this indicates a short to chassis that could energize the unit body.
Step-by-Step Troubleshooting
- 1
Disconnect power and access wash motor from below the tub
- 2
Check motor winding resistance (expect 3-10 ohms across terminals)
- 3
Spin motor shaft by hand — should rotate without catching or grinding
- 4
Measure capacitor (if present) with capacitance meter — replace if out of spec by >10%
- 5
If motor tests good, check board motor driver circuit for burned MOSFET
Pro Diagnostic Tip
Gaggenau dishwashers use the same BSH wash motor platform as Bosch 800/Benchmark series. Motor is interchangeable but the mounting bracket differs. The Gaggenau-specific bracket is included in the Gaggenau motor kit but not the Bosch kit — always order the Gaggenau-specific part number.
