Likely causes

  • An internal leak activated the base float
  • Excess foam or a spill reached the base
  • A hose, pump, seal, or water path is leaking
  • The machine was recently moved or tilted

Quick checks, in order

Turn off power and water

Disconnect the dishwasher and close its water supply.

Check for visible external leaks

Inspect around the door, hoses, and floor without removing panels.

Review detergent use

Hand-dish soap or excess detergent can create foam and leakage symptoms.

safe

Arrange leak diagnosis

The base must be dry and the leak source corrected before normal use.

Professional

What happened before E15 appeared?

Water is visible on the floor

Keep power and water off and arrange service. Do not run another cycle.

The wrong detergent was used

Stop the machine, remove foam safely, and allow professional inspection if E15 remains.

The machine was moved or tilted

Water may have shifted into the base, but a leak still needs to be ruled out before reuse.

Stop and get qualified help when

Do not continue troubleshooting if any of these apply:
  • Any water is near wiring or the outlet
  • The dishwasher trips the breaker
  • A panel must be removed to reach the base

Frequently asked questions

Can I clear E15 by tilting the dishwasher?

Tilting may move water away from the float without fixing the source. It can also spread water toward electrical parts, so it is not a safe repair method.

Will E15 reset after drying?

The code may clear after the base dries, but the dishwasher should not be used until the cause of the water is identified.

Keep diagnosing
