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.
Diagnose the internal fill system
What they doA qualified appliance technician should test the inlet valves, sensing and internal water path.
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.
Check both supply valves and hoses
Confirm that the hot and cold valves are fully open and their hoses are connected to the matching inlets without kinks.
Close both valves before loosening any hose connection.

Inspect drain-hose placement
Compare the visible drain-hose height and insertion with the installation guide so the washer cannot siphon while filling.
Do not alter fixed plumbing or force the hose into the standpipe.

Power-cycle once
Switch the washer off or unplug it for one minute, restore power and retry only after correcting visible supply or hose issues.
Do not repeat resets if the machine continues filling unexpectedly.
