How to Fix / Troubleshooting

Safety first: Turn off water and disconnect power before defrosting the ice maker.

  • Step 1 – Defrost assembly: Remove the ice bin and allow the ice maker to thaw completely. Use towels to catch water.
  • Step 2 – Inspect mold and housing: Look for cracks or warping that could allow water to spill into moving parts. Replace the ice maker assembly if damaged.
  • Step 3 – Test valve for seepage: With water on and ice maker off, check if water drips into the fill tube. Replace the Fisher & Paykel water inlet valve if it leaks.

After repair, monitor several cycles to ensure the mold fills and drains correctly without freeze-up.
