Name Description Repair Action
8 Pressure
Sensor Loss This determines if
there has been a
too great of a
difference in the
pressure sensor
reading and the
expected pressure
sensor reading for
the amount of
water the control
calculated it has
put in. It assumes
there is a pressure
leak, a clog in the
pressure
hose/system
delaying the
increase in
pressure, or a
significant amount
water leaking out.

Check house water supply are turned on.

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 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.
9 Lid Switch
Redundancy Start attempted for
a 4
th
cycle when
the previous 3
cycles have
completed with
backup micro
seeing lid open.
Could mean the
switches didn’t
occur or backup
processor didn’t
get the signal
because of lack of
connection. See
Fault # 2 as well.

Open and close the lid to clear the error.

Check harness and connectors that go to
the lid switch.

If the error will not clear, replace the lid
switch.
