Model compatibility: Bosch reuses codes across series and model years, so E9000 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

When to call a technician
If the warning returns, the supply should be verified before appliance components are replaced; internal power electronics may then require diagnosis. Do not choose the most expensive module from the code alone. The technician should verify the relevant circuit or mechanism before recommending a repair.
