Hotpoint dishwasher E15 error code
What E15 means on a Hotpoint dishwasher
Anti-flood sensor triggered: water in the base.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When a Hotpoint dishwasher shows E15, it means the anti-flood sensor has been triggered because there is water in the base of the machine. You may notice the machine beeping or its lights flashing, and it may stop draining or refuse to move on to the next part of the cycle.
Engineers sometimes find that the drain pump has become blocked or keeps sticking, so the dishwasher does not empty properly. They also sometimes find a sticky substance that has dripped down from the heater area into the base and set the sensor off, which can make the code appear only now and then.
An engineer will usually look for water or residue in the base, check whether the machine drains fully and test the drain pump. Where the pump has failed, they replace it, and this part may need to be ordered and fitted at a second visit. Any water or substance found in the base is cleared, and the engineer then runs the dishwasher through a cycle to make sure it is working normally again.

Before you check anything yourself
- Switch the dishwasher off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the dishwasher apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
