Possible Causes

Water leak from condensate system into base tray, Blocked condensate hose causing overflow, Cracked water tank or pump housing

How to Fix / Troubleshooting

Safety first: Unplug the dryer. Water and electricity are a dangerous combination.

Check for visible leaks:

  • Pull the dryer out and inspect underneath for water.
  • On models with a base tray, remove the lower front or side panel to access the tray and float switch.

Dry the base tray:

  • Carefully tilt the dryer (with assistance) to drain any water from the base tray, or soak it up with towels.
  • Ensure the float switch moves freely and is not stuck in the raised position.

Find the source:

  • Inspect the condensate pump, hoses, and water tank for cracks or loose connections.
  • Check the condenser housing seals for leaks.

Repair or replace any leaking components, then fully dry the base before reassembly. Do not operate the dryer until the leak source is corrected, as repeated leaks can damage electronics.
