Safe checks you can perform
- Preserve the exact evidence
- Keep the heating circuit closed
- Try only one controlled restart

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Model-specific Miele dishwasher diagnosis
What they doA qualified appliance technician should confirm the model generation and test the relevant pump, valve, relay, sensor, lock, harness, water path or controller.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Preserve the exact evidence
Switch the dishwasher off normally, photograph the complete display and record the model and serial number. Do not keep clearing the code.
Stop immediately for leakage, burning smell, smoke, repeated tripping, damaged cable or water near electricity. Close the tap where relevant; internal mains, heating and leak work is not user-serviceable.
Evidence: Miele dishwasher fault F26
Keep the heating circuit closed
Check only whether the code returns after a normal power-off interval. Do not open panels, bridge a relay, measure live voltage or test a heater.
Stop immediately for leakage, burning smell, smoke, repeated tripping, damaged cable or water near electricity. Close the tap where relevant; internal mains, heating and leak work is not user-serviceable.

Try only one controlled restart
After one documented external correction, reconnect and start one normal programme. If the code returns, stop and arrange Miele-qualified service.
Stop immediately for leakage, burning smell, smoke, repeated tripping, damaged cable or water near electricity. Close the tap where relevant; internal mains, heating and leak work is not user-serviceable.
