Introdução

Use this guide to troubleshoot a Midea washing machine that won’t fill with hot water, won’t fill with cold water, drips water into the tub when it’s off, or shows an E1 error code. You’ll check the water supply and inlet screens, test the water inlet valve solenoids with a multimeter, replace faulty valves, and perform electrical checks if the problem continues. Some valve and wiring layouts vary by model, but the testing approach is the same.

    • Unplug the washing machine before opening any panels or touching wiring.

    • Turn off the hot and cold water supply valves before disconnecting any hoses.

    • Keep a towel and a shallow pan nearby for any water left in the hoses.

    • Remove the hot and cold water supply hoses from the washer.

    • Test the hoses and water supply to confirm each hose will actually supply water.

    • If a hose doesn’t supply water, correct the supply issue before replacing any washer parts.

    • Inspect the inlet valve screens for debris with the hoses removed.

    • Use needle-nose pliers to pull the screens out of the valves to check the screens and behind them.

    • Wash and clean any clogged screens, then reinstall them.

    • A clogged screen can cause no-fill symptoms or an E1 error, and cleaning may solve the problem without replacing parts.

    • Use a Phillips screwdriver to remove the three top cover screws, located on the right, left, and in the middle between the valves.

    • Roll the washer console top forward to access the water valve area.

    • Make sure the washing machine is fully unplugged before doing any electrical testing or disconnecting harnesses.

    • Pull the wire harnesses off the water valve solenoids.

    • Set a multimeter to resistance (ohms), and use a 200 to 2000 ohms range if the meter isn’t autoranging.

    • Press the meter leads to the two metal prongs of a solenoid pair and read the resistance.

    • Expect roughly 1070 ohms on each solenoid pair (each valve coil).

    • If a reading is off by about 10% or more, the coil is likely damaged and the valve should be replaced.

    • If the washer slowly fills or drips water into the tub when off, the valve may be stuck open from debris and usually needs replacement.

    • Use a Phillips screwdriver to remove the two small screws from the metal arm in front of the valves.

    • Pivot the retainer up and away from the valves.

    • Remove the entire valve assemblies.

    • Use needle-nose pliers to pinch the hose retainer clamp and slide it farther back onto the hose.

    • Pull the water valve out of the hose.

    • Press the replacement valve into the hose, slide the clamp near the end of the barb, and release the clamp.

    • Some units use separate hot and cold valves, while others may use different mixing valves for features like fabric softener.

    • Reseat the valves into the small gaps in the plastic that hold the valves in place.

    • Reconnect the wire harnesses to the valves in the correct orientation.

    • Lift the bar onto the valves until it snaps into place, using a little maneuvering if needed.

    • Reinstall the two screws on the valve plate.

    • Roll the console top back into position and reinstall the three top cover screws.

    • Reconnect the water supply hoses and turn the water supply valves on.

    • Check for leaks at the hose connections, then run a fill to confirm hot and cold water operation.

    • Set the multimeter to AC voltage.

    • Pull the wire harnesses slightly off the valves to expose the metal of the harness, but don’t remove them completely.

    • Plug the washing machine in and command a fill by starting a cycle that calls for the valves to run.

    • Measure voltage at the solenoids and look for about 120 volts AC when the valve is commanded on.

    • If you don’t get 120 volts AC, the control board is likely faulty.

    • Unplug the washing machine before accessing the control board at the rear of the machine.

    • Unplug the control board connectors, especially the connector marked CN5.

    • Use a multimeter in ohms mode to test CN5 pin 1 to pin 6, then CN5 pin 2 to pin 6.

    • If the meter shows OL, the wiring is likely open somewhere between the board and the valves.

    • Inspect for breaks in the plastic bag that holds the conversion wires.

Conclusão

Water fill and slow-leak issues are commonly caused by a clogged inlet screen, a stuck-open valve, or a failed solenoid coil. If the valves test good and the washer still won’t fill, check for 120 volts AC at the valve during a commanded fill, then test the CN5 wiring path for an open circuit before replacing the control board.
