Fault Codes

Verify harness connections between User Interface (UI)
board and Main Control (MC) board.
Check thermistor, harness and connectors.
Check to see if pressure sensor is plugged in. If so,
then most likely pressure sensor is out of range, thus
replace pressure sensor. If this doesn't work, most
likely the wire harness has a short somewhere.
Check harness on pressure sensor and make sure it is
plugged in. If not, replace the pressure sensor.
Entering Circulate Test or Heater Test will Reset the
CSM. Always check the following before replacing the
main control. Inspect Exposed Heater (some models)
for splits, cracks, or zippering, replace if needed. Fill
and run Circulate Test several times to look for leaks.
Run Heater Test and drain.
Check thermistor, wiring and connections.
Check thermistor, wiring and connections.
Review Train Bulletin TB11-20.
Check that thermistor harness is plugged in. Check
that terminals are not bent inside connector housing.
Check that thermistor harness is plugged in. Check
that terminals are not bent inside connector housing.
Clear faults and cycle power to unit. If fault reoccurs
within 60 seconds of power up, replace MC board.
Cycle power and start cycle to clear fault. If fault does
not clear, replace main control board.
The pressure sensor has detected the water level
above the flood limit. Check the water valve for a stuck
open valve (continuous fill into the tub). Run the Fill
Test under the Diagnostics Test tab and ensure the
pressure sensor is in the range of 40.77 and 40.44 Hz.
Check that the fill funnel or door vent conduit at the
bottom of the door is not obstructed or blocked. This
can cause a pressure build up in the tub as the unit
heats during a cycle.
Check water valve to see if a water source is hooked up
to the dishwasher.
Possibly any error with dry heater/relay/fan.
Ignore fault.
Verify proper water level. Check heater. Check
thermistor. Check main control board.
Verify proper water level (no water will trip TCO).
Check heater TCO (replace TCO and harness if
Met tripped). Check heater. Check thermistor. Check main
control board.
