Introduction
An E3 error on a Criterion top-load washing machine commonly points to a lid lock system problem. This guide walks you through quick checks, safe disassembly, lid lock and magnetic switch testing, and replacement. These steps also apply to many similar Midea-manufactured washers sold under other brand names with the same lid lock design.
What you need
-
Step 1 Check the lid lock area and lid alignment
-
Inspect the lid lock housing for debris, and remove anything that could block the latch or switch movement.
-
Close the lid and confirm it sits flush against the top of the washer on all sides.
-
-
Step 2 Gather tools and plan for safe testing
-
Get a Phillips screwdriver, a multimeter, and a strong magnet.
-
Have painter’s tape ready to control the lid while the top is off.
-
Prepare a piece of wood or a metal rod to prop the lid open for two-handed testing.
-
-
Step 3 Disconnect power and water
-
Unplug the washing machine from the wall outlet.
-
Shut off the water supply valves.
-
Remove the water hoses and the drain hose as needed, and keep them suspended to reduce spills.
-
-
Step 4 Remove the rear top screws
-
Use a Phillips screwdriver to remove the two screws at the rear of the machine, one on the left and one on the right.
-
-
Step 5 Lift the top and secure the lid
-
Position the washer close to a wall so the lid can pivot up and rest against the wall behind it.
-
Apply painter’s tape across the lid to control it while it pivots upward.
-
Pull the top toward you, then lift it up so the lid can pivot up and away from the machine.
-
Hold the lid while pivoting if needed, especially if tape isn’t holding it securely.
-
Prop the lid open with a piece of wood or a metal rod so you can work with both hands.
-
-
Step 6 Access the lid lock and magnetic switch
-
Locate the switch assembly in the upper right corner under the lid.
-
Use a Phillips screwdriver to remove the three screws securing the plastic cover over the switch assembly.
-
Lift off the cover to expose the lid lock system.
-
-
Step 7 Remove the lid lock
-
Use a Phillips screwdriver to remove the two screws holding the lid lock in place.
-
Lift the lid lock out of its housing.
-
Press in the small retainer tab on the wire harness clip, and pull the harness free from the casing.
-
-
Step 8 Remove the magnetic switch
-
Use a small Phillips screwdriver to remove the tiny screw securing the magnetic switch.
-
Lift the magnetic switch out of the housing and separate it from its wire harness connector.
-
-
Step 9 Test the magnetic switch with a magnet
-
Set a multimeter to continuity or ohms resistance.
-
Press the multimeter leads into the magnetic switch harness contacts wherever you can touch metal, either at the front or just behind the plug.
-
Move a strong magnet close to the switch, and watch for the reading to change from open loop to continuity near 0.0 Ω.
-
If the switch won’t trigger with a magnet, replace the magnetic switch.
-
-
Step 10 Check for lid magnet and obstruction issues
-
Inspect the lid area near the switch location for damage or anything preventing the magnetic switch from cycling correctly.
-
Test the switch behavior with the top open if you suspect the lid magnet or an obstruction is the real issue.
-
-
Step 11 Test the lid lock with a multimeter
-
Confirm the white lock bar can be pressed in and out without obstruction.
-
Insert multimeter leads into the lid lock connector to test resistance on the correct wire pairs.
-
Measure blue-to-blue and confirm it reads between 30 and 60 Ω.
-
Measure the pair of black wires and confirm it reads OL with the bar extended and 50 to 80 Ω when the bar is pressed into the housing.
-
If the black-wire test still shows OL while the bar is pressed in, replace the lid lock.
-
-
Step 12 Install the replacement switch parts and close the cover
-
Position the magnetic switch in the housing and reinstall its screw.
-
Set the lid lock onto its two locating pegs, reinstall the two Phillips screws, and clip the wire harness into its retainer.
-
Reinstall the plastic cover over the switches and install the three Phillips screws.
-
-
Step 13 Reinstall the top and test for the E3 error
-
Align the top so it sits flush with the washer sides, then press it backward to lock it into place.
-
Maneuver the top as needed so it slides into place around the chassis screws and the impact switch.
-
Test the washer with the lid installed to see if the E3 error is gone.
-
-
Step 14 Rule out a weak or damaged lid magnet
-
Hold another strong magnet near the switch location to see if the washer stops showing the E3 error.
-
-
Step 15 Check the control board and lid lock wiring if E3 continues
-
Remove the screws along the back of the washer, then remove the two screws on the left side where the control board housing sits.
-
Lift the control board housing up and out, then remove the two or three screws holding its cover.
-
Press the housing edges to pop the top off and access the board connectors.
-
Disconnect the lid lock wires and test continuity between CN4 pin one and CN12 pin one with the lid open and closed, and repeat for the second wire while pressing the black switch in and out.
-
If a mode never shows the expected change, inspect the harness for damage, especially in bundled wire clusters.
-
If the lid lock and magnetic switch pass testing, the lid is aligned, and wiring tests good at the control board, the control board may be faulty. A commonly referenced control board part number is 17138000020922, but control boards vary by model, so match the board to the exact washer model before replacing it.
