Possible Causes

Internal leak from water circuit, Condensation drain hose disconnected, Cracked ice tray or reservoir, Overfilling due to stuck inlet valve

How to Fix / Troubleshooting

Safety: Immediately disconnect power and close the water supply valve.

Steps:

  • Access base pan: Remove the lower front or rear panel to reach the base pan and float switch. Sponge out all water.
  • Reset float: Ensure the float moves freely and returns to its rest position once dry.
  • Identify leak source: With water still off, inspect all visible hoses, joints, and the ice tray for cracks or mineral trails. Reconnect any loose drain hoses.
  • Test carefully: Turn water back on and observe for leaks while the unit fills. Be ready to shut off water immediately if dripping is seen.

Resolution: Replace damaged hoses, trays, or the inlet valve if it leaks when closed. Do not bypass the float switch; it is a safety device.
