Mabe Washer Error Code Er8

Lid lock error

Mabe codesMabe washer codes

Lid lock error - after 3 unsuccessful attempts to lock or unlock the lid, the washer stops and will no longer operate until unplugged and re-plugged or serviced.

First step from the service manual

Unplug and re-plug the washer; inspect lid lock solenoid, cam, locking pin, terminal 5 circuit, and wiring to control board.

What Er8 means on a Mabe washer

The Er8 error code on a Mabe washer signals a lid lock failure. Specifically, the control board has detected that the lid lock mechanism failed to complete either a locking or unlocking cycle three consecutive times. After the third failed attempt, the washer halts all operation and enters a locked fault state. The machine will not respond to any input until power is physically interrupted by unplugging the unit and reconnecting it, or until the underlying fault is resolved through service.

The lid lock system relies on a solenoid-driven mechanism that moves a locking pin into position via a cam assembly. When the control board sends a lock or unlock command, it expects confirmation through the terminal 5 circuit that the pin has engaged or retracted correctly. If that feedback signal does not arrive within the expected window, the board logs a failed attempt. Three failures in sequence trigger Er8. The fault can stem from a solenoid that is not receiving proper voltage, a cam or pin that is physically obstructed or worn, a broken or corroded wire in the terminal 5 circuit, or a connector that has lost continuity between the lock assembly and the control board.

Diagnosis should begin with a power cycle to rule out a transient software or electrical glitch. If Er8 returns, the next step is a physical inspection of the lid lock assembly, including the solenoid, cam, and locking pin for damage, debris, or wear. The wiring harness running from the lock assembly to the control board, particularly the terminal 5 circuit, should be checked for broken conductors, burnt insulation, or loose connectors. A failed solenoid will typically show incorrect resistance or no continuity when tested with a multimeter.

Common causes of Er8

  1. 01

    Faulty lid lock solenoid

    Part replacement

    The solenoid that drives the locking pin may be worn out, burned, or electrically open. Test it with a multimeter for proper continuity and resistance; a solenoid with no continuity or incorrect resistance must be replaced.

  2. 02

    Damaged or corroded terminal 5 circuit wiring

    Wiring / connection

    The wiring between the lid lock assembly and the control board, specifically the terminal 5 circuit, can develop breaks, corrosion, or loose connectors that prevent the feedback signal from reaching the board. Inspect the full wire run and connector pins for damage or poor contact.

  3. 03

    Worn or obstructed cam or locking pin

    Part replacement

    The cam and locking pin are mechanical components that can wear down, deform, or become blocked by debris over time. Visually inspect these parts for physical damage, misalignment, or foreign material preventing full travel.

  4. 04

    Loose or disconnected connector at the lock assembly

    Wiring / connection

    Vibration during spin cycles can work connectors loose at the lid lock assembly end or at the control board. Check both connection points and reseat any connector that shows signs of looseness or corrosion.

  5. 05

    Control board not sending proper signal

    Part replacement

    If the solenoid, wiring, cam, and pin all check out correctly, the control board itself may not be delivering the correct voltage command to the lock assembly. This is the least common cause and should be evaluated after all other components are ruled out.

Frequently asked questions about Er8

What does Er8 mean on a Mabe washer?
Er8 means the washer's lid lock mechanism failed to successfully lock or unlock three times in a row. The control board monitors the lid lock's terminal 5 circuit for confirmation that the locking pin engaged or retracted correctly. After three failed attempts, the washer shuts down completely and will not operate again until power is cycled or the fault is repaired.
Will unplugging my Mabe washer clear the Er8 error?
Unplugging the washer and plugging it back in can clear the Er8 error temporarily by resetting the control board's fault counter. However, if the underlying problem with the lid lock solenoid, cam, locking pin, or wiring is not addressed, the error will return after three more failed lock or unlock attempts. A power cycle is a useful first diagnostic step, not a permanent fix.
Is it safe to use my Mabe washer when Er8 is displayed?
The washer will not operate while Er8 is active, which is actually a safety feature. The lid lock system is designed to prevent the lid from opening during high-speed spin cycles. You should not attempt to bypass or defeat the lid lock mechanism, as doing so could result in injury from a spinning drum or water spillage.
How do I fix the Er8 error on my Mabe washer?
Start by unplugging the washer for a few minutes and plugging it back in to see if the error clears. If it returns, inspect the lid lock assembly for a damaged solenoid, worn cam, or stuck locking pin. Check the terminal 5 circuit wiring and all connectors between the lock assembly and the control board for breaks, corrosion, or loose connections. Replace any components that fail a visual or multimeter inspection.
How much does it cost to repair an Er8 error on a Mabe washer?
Repair costs vary depending on the failed component. A lid lock assembly replacement typically runs in the range of $30 to $80 for the part itself. If the issue is only a damaged wire or loose connector, costs can be minimal. Adding professional labor, total repair bills commonly fall in the $100 to $250 range, though a control board replacement would push costs higher.
