Error Code OE

Drain Error — not fully drained within 10 minutes

What This Means

Pump motor connector broken or loose; Water level frequency below 25.0 kHz (air chamber, tube, or pressure switch clogged); Drain pump coil resistance out of range (should be 10-20 Ohm); Voltage between connectors NA2 pin1 to BL3 pin1 out of range; MAIN PWB Assembly defective; Drainage hose kinked, bent, frozen, or clogged; Improper substance blocking drain pump

How to Fix

1. 1

   Confirm OE is displayed.

2. 2

   Check pump motor connector (circulation pump and drain pump) for damage or looseness — reconnect or repair.

3. 3

   Press Soil + Delay Wash simultaneously to check water level frequency. If below 25.0 kHz, check air chamber, tube, and pressure switch.

4. 4

   Check coil resistance of drain pump (should be 10-20 Ohm). If out of range, replace Drain Pump Assembly.

5. 5

   Check voltage between NA2 pin1 and BL3 pin1: running pump should be 120VAC ±5%; stopped motor/pump should be 0-1V. If out of range, replace MAIN PWB Assembly.

6. 6

   Test pump speed using Spin+Soil hold, then POWER, then START/PAUSE: 2 presses = slow speed, 3 presses = mid speed, 4 presses = high speed, 5 presses = stop.

7. 7

   Installation check: hose not in lower position, not bent/clogged, not frozen, no foreign substance in pump.
