Safety first
Stop and check this first
- Disconnect the washer if AC returns, controls flicker, a breaker opens or there is heat or electrical odour. Do not open the console.
Safe checks you can perform
- Disconnect power for one controlled reset
- Confirm the external supply arrangement
- Record the full code and operating stage

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.
Trace the model-specific communication link
What they doA qualified technician should inspect harness continuity, connectors, board supplies and communication between the named control modules.
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.
Disconnect power for one controlled reset
Switch off and unplug the washer from a dry outlet for two to three minutes, then restore power and retry only once.
Disconnect the washer if AC returns, controls flicker, a breaker opens or there is heat or electrical odour. Do not open the console.
