Possible Causes

Cracked Haier sump assembly, Loose hose clamps, Leaking circulation pump seal, Damaged drain hose

How to Fix / Troubleshooting

Safety first: Disconnect power and water supply immediately. Avoid standing in water near electrical connections.

  • 1. Remove toe-kick and inspect: Look into the base pan for water and trace drips while running a short cycle.
  • 2. Check hoses and clamps: Inspect the drain hose, circulation hose, and inlet hose for cracks or loose clamps. Tighten or replace as needed.
  • 3. Inspect sump and pump seals: Examine the Haier sump assembly and pump seals for cracks or signs of leakage. Replace the sump gasket or pump if leaking.
  • 4. Replace damaged components: Any cracked plastic parts (sump, pump housing) must be replaced; they cannot be reliably glued.
  • 5. Dry base and test: After repairs, dry the base pan completely and run a test cycle while monitoring for leaks.

Warning: Water in the base can trigger anti-flood devices; ensure it is fully dry before reassembly.
