Address soon - your appliance may not work properly
What This Means
Drain pump connector disconnected or pump disassembled; Pump connector or connection connector faulty on PCBA; Drain hose kinked, clogged, frozen, or positioned too low; Pump coil resistance out of range (should be 1.5–4 Ω); Air chamber or pressure tube clogged (water level frequency below 26.0 kHz in service mode); Faulty PCBA
How to Fix
- 1
Is OE displayed? Yes — proceed
- 2
Check if pump motor connector is disconnected: Yes — reconnect or repair the connector
- 3
No — enter SVC mode; is water level frequency below 26.0 kHz? Yes — check air chamber, pressure tube for clogs; clear obstruction
- 4
No — check drain pump coil resistance (1.5–4 Ω on pins 1-2, 2-3, 3-1): if out of range, replace drain pump assembly
- 5
If resistance is OK but OE persists, replace main PCB assembly
- 6
Environmental checks: drain hose must not sit lower than washer; must not be bent, clogged, or frozen; must not insert more than 12 in (30 cm) into standpipe; end must be 39 in (99 cm) above floor
