Name Description
5 Mode Shift If the mode shifter fails
to complete a shift, it will
retry two more times. If
it still doesn't complete a
shift; it will set this fault.
6 Critical Flood The critical flood level
Level by by pressure algorithm is
Pressure tripped as defined here:
Flood Protection
Algorithm.
7 Power relay One of the power relays
stuck on on the TL28 IMC direct
drive model is stuck on.
8 Pressure The pressure sensor loss
Sensor Loss algorithm set conditions
are described here:
Flood Protection
Algorithm.
9 Lid Switch This fault is set if 3
Redundancy consecutive cycles are
started without seeing the
lid open.
Repair Action
• If lid does not lock, use Service Mode Test 13
to confirm lid switch is functional.
• Use Service Mode Test 14 to put the unit into
spin mode.
• Check resistance of the mode shifter motor.
Make sure it matches the value on the wiring
diagram.
• Check continuity of the mode shifter switch.
• Check mode shifter coupler for damage and
the ability to slide in and out freely.
• Check for 120 VAC to the mode shifter motor
at the control connector.
• Check pressure tube for pinches where it
goes through top cover grommet.
• Check pressure tube for trapped water.
• Check water valve operation and for any
leaking water valves.
• Use Pressure Sensor Test 10 to ensure
correct pressure sensor operation.
• Ensure pressure chamber port is free from
obstruction using drill bit size 1/16-in. by hand
so as not to drill through the inner wall.
• Replace main board.
• Check to make sure house water supply
valves are turned on.
• Check water valve operation.
• Check pressure tube for pinches where it
goes through top cover grommet.
• Use Pressure Sensor Test 10 to ensure
correct pressure sensor operation.
• Check pressure tube for trapped water.
• Ensure pressure chamber port is free from
obstruction using drill bit size 1/16-in. by hand
so as not to drill through the inner wall.
• Open and close the lid to clear the fault.
• Check harness and connectors that go to the
lid switch.
• Use Test 13 to ensure system can detect the
correct lid state with the Spin and Rinse LEDs.
• Consumer education that 4 cycles cannot be
run back-to-back without opening and closing
the lid.
• If the fault will not clear, replace the lid switch.
