E10 means a filling problem during washing on the Midea L11 platform. Start with the external water supply; the technical chart does not authorize testing valves or boards at home.
The match is verified in the official L11 technical manual. Operating and maintenance steps should come from the manual for the installed model.
Check what may be blocking water from entering
Make sure the shutoff valve is open and that there is a water supply. See whether the hose was bent when the washer was pushed into place. If water enters but the level does not stabilize, also note whether it seems to be draining out; do not add water by hand to bypass the warning.
Disconnecting hoses or cleaning strainers requires the user procedure, with the water shut off first and power disconnected. Do not copy resistance measurements or connector tests from the technical manual.
If E10 appears again with the external conditions correct, request a diagnosis of the filling system and its detection. The L11 alarm timeout does not apply as a limit to other Midea models.
Provide the code, model reference, and observation of the incoming water; that information is more useful than asking for a solenoid valve based on the message.
