Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Neff dishwasher, E25 means a drain fault. It is often caused by a blocked drain pump, and it has also been seen when water has collected in the base of the machine. You may notice the dishwasher not draining, beeping or flashing lights, stopping part way through a cycle or not starting at all.
Some drain pumps have worn out and become noisy, rattling or struggling to turn. Others have been blocked by debris such as broken glass. Engineers also sometimes find a blocked drain filter or a partly blocked waste pipe. Now and then water in the base turns out to come from a worn lower door seal.
An engineer will usually drain off any standing water, check the filter, the pump and its cover, and look along the waste pipe for blockages. Debris can often be cleared there and then. If the pump itself has failed, it is replaced, and a new door seal is fitted where that is the source of the water. A replacement pump often has to be ordered and fitted at a second visit.

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.
