To remove the lid switch:
1. Remove the front panel (see Front Panel).
2. Reach under the lid assembly and locate the lid switch.
Squeeze the lid switch latch in to release it while gently
pushing the switch upward, then guide the lid switch through
the opening.
Lid Switch Diagnostics
To determine if the lid switch circuit is operating normally, enter Service Mode (see Service Mode).
Press the CUSTOM 2 pad to advance to the Lid Switch Test mode. While in this mode, if the lid switch
is operating correctly, the Digital Seven Segment Display (DSSD) should display OPn when the lid is
open and CLS when the lid is closed.
Note: If service mode indicates a defective lid switch, confirm this diagnosis by verifying that the
magnet is attached to the lid, checking the lid switch connections, and by manually checking the
continuity of the switch before replacing.
Lid Lock
The lid lock is mounted by 2 Phillips screws under the top panel at the front of the lid opening. It is a
safety feature which prevents the lid from being opened when the basket is spinning. The lid lock is
controlled by the electronic control board, which monitors the speed sensor for transmission rotation.
When 50 rpm is sensed, the electronic control board will energize the lid lock with 12 VDC, locking the
lid. The lid lock will remain energized until the electronic control board determines that the basket has
stopped spinning.
Should the lid lock fail, and the lid switch be opened during spin for more than 5 seconds, the electronic
control will limit high speed spin to 630 rpm and log the lid lock error code. Spin speed will be limited to
630 rpm until the lid lock error is reset in the service mode.
Warning: The lid lock will not be activated by the electronic control board if the speed sensor is faulty,
disconnected, or has an open in the circuit.
To test the lid lock:
1. Unplug the unit for 15 seconds, then plug the unit back in. If the lock is functioning correctly, the lid
lock will briefly activate when power is applied.
2. Place the unit in spin using service mode or the Drain & Spin cycle. The lock should activate when
50 rpm is attained.
If the lid lock does not activate when power is remove and restored, suspect a faulty lid lock or
electronic control board. If the lid lock activates when power is applied, but does not activate when the
unit is spinning, suspect a faulty speed sensor or speed sensor wiring.
