Error Code List Part 1
Error type Error Occurring condition
Mode
Water supply 4E 1. When the pulse of 100 or less is detected
Error
even 1 minute after the water supply
2. When flow meter pulse is 5 or less 5 seconds
after the water supply starts
3. When the water supply does not occur 5
minutes after the water supply starts
4E1 When 176 ℉ or above is detected during
water supply
Drain Error 5E When OFF status of Low Level switch is not
detected within 3 minutes during the drain
Overflow oE When overflow detection AD data is 4.0V or
Error below for 3 seconds
(When leakage sensor detects 4.0V or below
for 1 seconds during water supply)
Leakage LE When leakage sensor detects 4.5V or below
Error for 1 seconds
Expected condition
Water supply valve defect - a normally operating
water valve should measure ~ 1200 Ω out of the
circuit. Also verify the 120VAC supply from the main
PCB is present
Flow Meter defect
Foreign particles within water supply valve
Water supply valve terminal not connected
Main PBA defect
Thermistor Defect
Water supply temperature of 176 ℉ or above
Main PBA defect
Drain pump defect – a normally operating drain
pump should measure ~ 25 Ω out of the circuit, also
verify the 120VAC supply from the main PCB is
present
Low Level Sensor defect
Foreign particles clogging mater drain hose
Drain valve terminal not connected
Main PBA defect
Foreign particles within water supply valve
Case Sensor part leakage
Flow Meter defect
Main PBA defect
Base part hose connection defect
Sump and Tub assembly defect
Drain Pump assembly defect
Main PBA defect
