Dishwasher will not start and shows E15; often the drain pump runs continuously.

Safety first: Disconnect power and close the water tap. Be prepared for water spillage when tilting the machine.

E15 means water has collected in the base pan and activated the float switch, triggering AquaStop.

• Step 1 – Remove standing water:
  • Pull the dishwasher out from the cabinet.
  • Carefully tilt it about 45° backward to allow water to drain from the base (have towels ready).
  • Return the dishwasher upright and let it dry for several hours.
• Step 2 – Identify leak source:
  • Remove the base cover to access the underside.
  • Look for water trails from the sump, hoses, heat pump, or water matrix.
  • Check the door seal and bottom door area for leaks during a test fill.
• Step 3 – Common leak points:
  • Sump-to-tub seal deteriorated.
  • Cracked plastic on the heat pump or water matrix.
  • Loose hose clamps on circulation or drain hoses.
  • Overfoaming from incorrect detergent or rinse aid overdose.
• Step 4 – Repair:
  • Tighten or replace leaking hose clamps.
  • Replace cracked components (sump, heat pump, water matrix) as needed.
  • Replace the sump seal if leaking around the sump.

Do not bypass the leak safety system; always fix the underlying leak before returning the dishwasher to service.
