Bosch dishwasher E25 error code
What E25 means on a Bosch dishwasher
Drain fault, often a blocked drain pump or pump cover.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Bosch dishwasher, this code means a drain fault: the machine cannot pump its water away. It is often caused by a blocked drain pump or pump cover. You may notice water left sitting in the bottom of the machine, beeping or flashing lights, or unusual noise while it tries to drain.
Engineers sometimes find something caught in the pump that stops the small spinning part inside it from turning freely, such as a piece of broken glass, a nut shell or a tangle of fluff. Sometimes the pump cover has worked loose or was not sitting properly, or there is a blockage further along in the waste pipe. At other times the drain pump itself has seized or failed.
An engineer will usually check whether water is left inside, clear any blockage in the pump and waste pipe, make sure the pump cover is fitted securely, and then run the machine to confirm it fills and drains properly. If the pump has failed, they replace it. A new pump may need 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.
