Symptoms

  • Drain pump runs constantly and will not stop
  • Dishwasher will not start a cycle
  • E15 on the display

Common Causes

1
Water collected in the base pan

A small leak or condensation pooled in the base and lifted the foam float.

2
Active leak from a hose/seal

A worn pump seal or loose hose clamp.

How to Fix It

  1. Tip the dishwasher back ~45 degrees to drain water out of the base pan (place towels).
  2. Stand it back up — the E15 often clears once the float drops.
  3. If it returns quickly, find and fix the leak source (pump seal, hose clamp).
