What the E15 Error Means
The E15 error code indicates that water has collected in the base of the dishwasher. A float switch in the base tray detects the presence of water and triggers the flood protection system, shutting down the cycle and activating the drain pump to remove the water. The machine will continue to attempt to drain until the base is clear.
Common Reasons This Error Appears
Internal leak
A leaking hose, pump seal, door seal or spray arm connection can allow water to drip into the base tray and trigger the float switch.
Overfilling
If the water inlet valve or pressure sensor is faulty, the machine may overfill and water can overflow into the base.
Excessive detergent or foam
Using too much detergent or the wrong type can generate excessive foam that seeps into the base and activates the flood protection.
Condensation build-up
In some cases, significant condensation can accumulate in the base over time and eventually trigger the float switch.
Safe Checks You Can Try
Allow the machine to drain
Leave the dishwasher switched on as it will continue trying to pump water out of the base. Once the base is clear the error may reset automatically.
Tilt the machine slightly forward
With the power off, carefully tilting the machine forward can help water in the base drain towards the pump. Place towels on the floor first.
Check detergent usage
Ensure you are using the correct type and amount of dishwasher detergent. Avoid using washing up liquid or standard soap in the machine.
Inspect for visible leaks
Check around the door seal and underneath the machine for any signs of water or dampness.

When To Contact A Professional

Internal components should only be inspected or repaired by trained professionals.
