Error Code OE
Drain Error — tub not fully drained within 10 minutes.
Moderate
Address soon - your appliance may not work properly
What This Means
Pump motor connector broken or loose; Air chamber, tube clogged, or pressure switch fault causing water level frequency below 25.0 kHz; Drain pump coil resistance out of range (should be 10-20 Ω); Voltage between connectors NA2 pin1 to BL3 pin1 out of range; MAIN PWB ASSEMBLY failure; Drain hose kinked, clogged, or end submerged; Foreign material inside drain pump
How to Fix
- 1
Confirm OE is displayed.
- 2
Check if pump motor connector (circulation pump or drain pump) is broken or loose. If YES → reconnect or repair connector.
- 3
If NO → press WASH/RINSE and DELAY WASH simultaneously; check if water level frequency is below 25.0 kHz. If YES → check air chamber, tube (clog), and pressure switch.
- 4
If NO → check drain pump coil resistance: should be 10-20 Ω. If out of range → replace DRAIN PUMP ASSEMBLY.
- 5
If resistance OK → check voltage between connectors NA2 pin1 to BL3 pin1. Running pump: 120 VAC ±5%; stopped motor/pump: 0-1V. If out of range → replace MAIN PWB ASSEMBLY.
- 6
Test pump via load test mode: hold SPIN SPEED + SOIL LEVEL, press POWER. Press Start/Pause: 1x=slow, 2x=mid, 3x=high, 4x=stop.
- 7
Check drain hose is not kinked, not submerged, and end is less than 96 inches (8 ft / 2.4 m) above floor.
- 8
Check drain pump for foreign material or improper substance causing breakdown.

Related Error Codes
Suds Error — too many suds detected. Machine adds a Suds Reducing cycle (adds approximately 2 hours to cycle time). If too many suds detected during spinning, machine stops to prevent leaking.
Pressure Sensor Error — PRESSURE SENSOR ASSEMBLY is out of order; water level frequency consistently below 10 kHz or over 30 kHz. Note: PE error will not disappear when START/PAUSE is pressed; if unresolved within 20 seconds power turns off and error blinks.
Locked Motor Error — motor or motor harness fault.
Unbalance Error — load balance issue prevents spin.
Overflow Error — water is overflowing; water level frequency is over 21.3 kHz. Note: when FE is displayed, the drain pump will operate automatically to drain water. Power will NOT be turned off automatically.
Door Open Error (variant) — door switch circuit fault, same root causes as dE1.
EEPROM Error — EEPROM is out of order. Displayed only when START/PAUSE button is first pressed in Load Test Mode.
Power Failure — power supply was interrupted while washing machine was in operation, then power was rapidly restored.
