Loose clamp on tub-to-pump hose, Cracked tub-to-pump or pump-to-hose rubber, Leaking drain pump housing, Split external drain hose

How to Fix / Troubleshooting

Safety first: Unplug the washer and turn off water supply. Tilt the machine only with assistance to avoid injury.

Step-by-step checks:

  • Access underside: Remove the rear panel or tilt the washer slightly back to inspect the bottom. Use a flashlight to locate the source of the leak.
  • Check tub-to-pump hose: Inspect the large black hose from the bottom of the tub to the pump. Look for cracks, pinholes, or loose clamps. Tighten clamps or replace the hose if damaged.
  • Inspect pump housing: Look for water seeping from the pump body or shaft. If the pump leaks, replace the drain pump assembly.
  • Examine external drain hose: Follow the hose from the pump outlet to the household drain. Replace if split or kinked.
  • Test after repair: Run a short fill and drain cycle while observing for leaks before reassembling panels.
