How to fix this safely

- Run one hot maintenance or normal programme only after refitting the filter securely.
Can I fix this myself?
YesYou can carry out simple external checks such as filters, hoses, visible water, and correct loading. Stop when the fault points to internal pumps, heaters, wiring, or controls.
Safety boundary: Disconnect power before accessible checks. Do not remove panels, bypass safety devices, work on wiring, or run the dishwasher if water may be reaching electrical parts.
What not to do
- Do not keep repeating resets if the same code comes back.
- Do not remove panels or work on internal wiring, pumps, valves, or heater parts.
- Do not ignore leaks, burning smells, or unusual pump noises.
Reset steps
- Restore power only after the safe external checks are complete and the area is dry.
- Run one short test programme if there is no visible leak, smell, or electrical concern.
- Stop if the code returns or the dishwasher fails to fill, heat, drain, or wash normally.
Intermittent vs persistent faults
A one-off warning may clear after safe external checks, but repeated Bosch dishwasher faults should be treated as a persistent problem that needs diagnosis.
