How to Fix

  1. 1

  4. 4

    If NO → check drain pump coil resistance: should be 10-20 Ω. If out of range → replace DRAIN PUMP ASSEMBLY.

  5. 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. 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. 7
