AEG dishwasher E11 error code
What E11 means on an AEG dishwasher
Water inlet fault: the fill is taking too long.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On an AEG dishwasher, E11 means there is a water inlet fault: the machine is trying to fill, but the fill is taking too long. You may also notice beeping or flashing lights, the dishwasher not filling with water, or it stopping part way through a cycle.
Engineers sometimes find that the small chamber linking the sump to the pressure switch, the part that senses how much water is in the machine, has become blocked. They have also found the pressure switch itself clogged with mould, or failed altogether. Sometimes the cold water supply pipe behind the machine has been squashed, so no water can get in.
An engineer will usually run the dishwasher to watch how it drains and fills, then check the pressure chamber and switch, clearing out any blockage and testing the switch. A blocked chamber or a clogged switch can often be cleaned and put right there and then. If the switch has failed it is replaced, and because it may need to be ordered, fitting it can mean a second visit. They will also check that the supply pipe is not squashed, then run the dishwasher to make sure it fills and washes properly.

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.
