Whirlpool Washer WTW5640XW Lid Wont Unlock

6 posts in this topic

I have a whirlpool bought from Lowes 30 days ago. Went to start a load Sat night, put in a few items then shut the lid and hit start. Never fiiled with water - Lid lock display light was flasing red for over two hours so I unplugged it and let it sit overnight. Plugged back in, in the a.m. and the lid lock red light flashed for two seconds then went red. The Model number on this model is WTW5640XW. Its the High efficency model with the Ecoboost option. Top loader. Is this something I can fix or do I need a repairman?

LID LOCK FAULT

Fault is displayed if Lid Lock has not moved into locked position or motor cannot be powered.

Lid is not closed completely due to interference.

Check for lock interference with lock striker.

Wash media buildup (detergent, lint, etc.) is preventing the lock mechanism from sliding.

Main control detects open lid switch when attempting to lock.

Main control cannot determine if lid lock is in a locked state.

Perform the following checks if the washer does not lock (or unlock).

1. Perform the Lid Lock test under Manual Test Mode on page 9. The following steps assume that this step was unsuccessful.

2. Check lid lock mechanism for obstruction or binding. Repair as necessary.

3. Unplug washer or disconnect power.

4. Remove console to access main control.

5. Visually check that the J15 connector is inserted all the way into the main control.

If visual check passes, go to step 6.

If connector is not inserted properly, reconnect J15 and repeat step 1.

6. Remove connector J15 from main control. With an ohmmeter, verify resistance values shown below across the following J15 connector pinouts:

LID LOCK RESISTANCE

Component . . . . . . . . . . . . . Resistance . . . . . . . . . . . . Contacts Measured

Lock Switch Solenoid . . . . .85 to 155 ohms . . . . . . . . . . . . J15-1 J15-3

Lock Switch . . . . . . . .Locked = 0 Ω / Unlocked = ~ . . . . . . J15-3 J15-4

Lid Switch . . . . . . . . . . . Closed = 0 Ω / Open = ~ . . . . . . . J15-3 J15-2

If resistance values are good, go to step 7.

If switch measurements do not match the values shown in the table for unlocked (or locked) condition,

a problem exists in the lid lock. Replace the lid lock mechanism.

7. If the preceding steps did not correct the lock problem, replace the main control.

a. Unplug washer or disconnect power.

b. Replace the main control.

c. Reassemble all parts and panels.

d. Plug in washer or reconnect power.

Calibrate washer and perform Automatic Test to verify repair.

For others coming along in the future, here's part link to the lid switch... http://www.repairclinic.com/PartDetail/Latch/W10404050/1938607

And here's how to replace it:

- Tape down the lid

- Remove the top screw from both hinged in back of the control panel.

- Slide the top panel forward about 1/2"

- Raise the front of the top panel up a bit

- While keeping the front lip lifted, push it back a bit

- Now tilt the top panel up on the rear hinges

Just today I fixed a wtw4950xw0 with the esact same symptoms. I found one wire broken at the terminal where it plugs into the run capacitor.Might not hurt to tip it up and have a look at wire connections underneath. The location and way this one was mounted seem to cause alot of movement to wiring during wash.
