Fisher & Paykel Washer · Error code 12

What 12 Means

Fault 12 on a Fisher & Paykel top-load washer is a flood-protection error — water was detected above the flood level and the washer stopped to prevent overflow.

Symptoms

  • Washer stops mid-cycle
  • Possible water in the base
  • Fault 12 (or "12") shown

Common Causes

1
Water valve stuck open

The inlet valve keeps filling beyond the safe level.

2
Pump or drain blockage

A blocked drain prevents the water from leaving.

3
Motor control module fault

Less commonly, the control mis-reads the level.

How to Fix It

  1. Turn off the water supply to stop any fill.
  2. Clear the drain pump and hose of blockages.
  3. If the washer keeps overfilling with the cycle off, the inlet valve is stuck — replace it.
