Error Code OE

Drain Error — machine does not reach normal drain level (motor RPM not increasing or drain blocked)

What This Means

Filter assembly blocked; Drain hose kinked or blocked; Inner hole of drain case blocked; Air gap clogged; Knockout plug of garbage disposal not removed; Washing motor locked or defective; Wiring connection to drain motor (YL3) disconnected; Drain motor impeller stuck; Drain pump resistance out of range (should be 4-5 ohm); Outer drain hose kinked, blocked, or frozen; Controller damaged

How to Fix

1. 1

   Check if drain motor operates: if Motor RPM not increasing — verify connector YL3 is connected to main PCB

2. 2

   Check drain pump resistance (4-5 ohm); replace drain pump if out of range

3. 3

   Check voltage between YL3 pin1-2-3: should be 12V AC ±15%; replace main PCB if out of range

4. 4

   If Motor RPM is increasing: check if filter is clogged and clean it

5. 5

   Check if air gap is blocked and clean it

6. 6

   Remove knockout plug from garbage disposal if not done

7. 7

   Check if outer drain hose is kinked, blocked, or frozen and remove cause

8. 8

   Check if inner hole of drain case is blocked; repair or replace drain motor

9. 9

   Repair drain motor when impeller is stuck; replace drain motor if error persists

10. 10

    Replace pump casing assembly if washing motor not working properly

11. 11

    Replace main PCB assembly if all checks pass
