Fault
CODES
DESCRIPTION SUSPECT Technical Description
Temperature Sensor error
TE1
Thermister
Main PCB
Thermister terminal not connected
Possible defect : Thermistor , Main PBA
Heater error
HE
Open Heater
Heater Relay
Main PCB
Heater terminal not connected Possible defect : Main Wire-Harness, open
Heater or Heater Relay, Main PBA
High temperature
Heating error.
HE1
Heater relay
Main PCB
Thermister
Water temperature sensed above 176F during operation Possible defect :
Thermistor , Main PBA or shorted heater relay
Low-level water error
9E
Low level Sensor Level sensor fails to close after 1.2 gallons of water is metered in. If water is
present check for level sensor float stuck in empty position or bad switch
Water supply error
4E
Flow Meter
Water Valve
No Water Supply Main PCB does recognize proper or no water flow through flow meter.
Check supply and water valve
High temperature
Water supply error
4E1
Incoming Water Temp
sensed above
176F
Faulty Thermister or Main PCB / Incoming water is over 176F
Drain error
5E
Level sensor fails to open
after 3 minutes of drain
Evaluate Drain Operation / Possible kinked drain hose / obstruction in
pump or sump assembly. If water has drained check for level sensor stuck
in closed position.
Over-level Error
OE
Water reaches top of level
sensor container
Suspect stuck water valve / Faulty flow meter or possible drain issue.
Leakage error
LE
Water Present in Base of
D/W
Inspect for leaks / if no leaks present unplug sensor if code goes away
replace leak sensor if not check harness for short or pinched wire before
replacing Main PCB
Button error
6E2
Stuck Button When a button is pressed continuously for 30 seconds.
Check panel alignment / Main or Sub PCB failure
Door open warning Door is open in wash or at
start
Door is not close properly.
Possible defect : Door lock switch, Main PBA
