trapped water.
 Check for any leaking water
valves.
 Check home water pressure.
 Check the output voltage from
the pressure sensor to ensure
it matches the water level in
the basket according to the
pressure sensor chart.

Fault 6, 7, or 12 occurs.
 Check pressure tube for
pinches where it goes through
top cover grommet.
 Check pressure tube for
trapped water.
 Check for any leaking water
valves.
 Check home water pressure.
 Check the output voltage from
the pressure sensor to ensure
it matches the water level in
the basket according to the
pressure sensor chart. If it
does not, the control will need
to be replaced as the pressure
sensor is mounted directly to
the control.
22 Out of Balance
(OOB) during Dry
Load Sense.
Large wet/OOB load being washed. This is
set if OOB condition is detected during dry
load sense algorithm. Dry load sense will
be abandoned and wet load sense will be
started.
1. Check for excessively OOB
load. Customer Education on
how to distribute load.
2. Check the basket for excessive
friction or for being excessively
out of round. Basket should
spin freely and without wobble.
If friction is found, remove it. If
basket is bad, replace it.
23 Critical Lid Lock 1. Lock blockage
2. Lid Lock fault. Will not lock or unlock or
is locked while lid is opened.
 Verify that the lid lock is not
blocked by any external debris.
 Check lid switch continuity at
J513 on the control.
 Check continuity of lid lock
position. Opened or Closed.
 Check for proper operation
of lid lock. 120 VAC while
activating.
 Check lid lock wiring harness
from the control to lock
assembly.
24 Lid Logic Failure Lid switch fault.
This fault is set if the system perceives the
lid to be both OPEN and LOCKED for 5
consecutive seconds
1. Check harness and
connections from the control
to the lid lock assembly for
damage and continuity.
2. Run a spin cycle. Pull up on
the lid during spin for more
than 5 seconds and see if this
fault occurs. Replace lid lock
assembly.
