Error Code OE

Q: What does error code OE mean on a LG washers?

Drain Error - machine unable to drain within expected time Connectors at main PCB and drain pump loose or disconnected; Water level above 250 (air dome or pressure hose clogged, pressure switch fault); Drain pump motor resistance outside 1-20 Ohm range; Voltage at main PCB connectors NA4-1 BN and BL3-1 BK not 120 VAC +/-5%; Kinked or clogged drain hose; Frozen drain hose; Foreign objects clogging drain pump filter; Foreign objects caught in pump impeller

Drain Error - machine unable to drain within expected time

Moderate

Address soon - your appliance may not work properly

What This Means

Connectors at main PCB and drain pump loose or disconnected; Water level above 250 (air dome or pressure hose clogged, pressure switch fault); Drain pump motor resistance outside 1-20 Ohm range; Voltage at main PCB connectors NA4-1 BN and BL3-1 BK not 120 VAC +/-5%; Kinked or clogged drain hose; Frozen drain hose; Foreign objects clogging drain pump filter; Foreign objects caught in pump impeller

How to Fix

1
Confirm OE is displayed
2
Check connectors at main PCB and drain pump - reconnect/repair if loose or disconnected
3
Press WASH/RINSE and DELAY START simultaneously - check if water level is less than 250
4
If water level not less than 250: check air dome and pressure hose for clogging; check pressure switch (test #2)
5
If water level less than 250: measure resistance of drain pump motor
6
Drain pump resistance should be 1-20 Ohm - if outside range, replace DRAIN PUMP ASSEMBLY
7
Check voltage between main PCB connectors NA4-1 BN and BL3-1 BK - should be 120 VAC +/-5%
8
If voltage incorrect: replace MAIN PWB ASSEMBLY
9
To test drain pump: turn on washer, press SPIN SPEED to LOW, press START/PAUSE
10
Always check external causes: kinked/clogged drain hose, frozen hose, clogged filter, impeller obstruction
