Possible Causes

Cracked tub-to-pump hose, Leaking drain pump seal, Loose hose clamps, Split inlet hose inside cabinet

How to Fix / Troubleshooting

Safety first: Unplug the washer and turn off water supply. Expect water spillage when opening the cabinet.

Step-by-step checks:

  • Identify leak location: Remove rear and/or side panels. Run a short fill cycle while observing the underside with a flashlight.
  • Check tub-to-pump hose: Inspect the large black hose from the tub to the pump for cracks or loose clamps. Replace or tighten as needed.
  • Inspect pump: Look for water around the pump body and shaft. A leaking pump seal requires pump replacement.
  • Examine internal inlet hoses: Check hoses from the inlet valve to the detergent drawer and from the drawer to the tub for splits or loose connections.
