Bosch, Neff or Siemens Dishwasher not emptying fault E25 Error Code

This video will show you how to clean filter and unblock the Dishwasher pump to clear the Bosch, Neff or Siemens E25 error code fault

Other type of Bosch, Neff or Siemens Dishwasher pump cover


The most common in my view is the impeller jamming on the pump normally something small like a piece of chipped china or bit of broken glass, this can be removed with tweezers or pin nose pliers. After removing it should rotate easily by hand… then you should replace the pump cover and the filter above it must be locked by aligning the blue arrows so that large bits of rubbish cannot get into the impeller again.

There are two types of pump covers one is held on with a screw and the other clips into place.


In a lot of people’s houses they have the dishwasher plumed into a sink unit and the fittings can get clogged and also blocked with fat, some have a cross inside the spigot and this gets blocked with all kinds of stuff.

When you push the dishwasher into place the pipes can get trapped and kinked so make sure that this does not happen. Sometimes the waste pipe has kinked when it was fitted and over time the dishwasher is getting worse at emptying and this is when the E25 fault starts occurring.dishwasher trapped or kinked waste hose

Bosch, Neff or Siemens Dishwasher prone to the seal failing and water can get insideThe last fault is the pump has failed or it is only working intermittently. The new type of modern pump has the armature inside the pump housing and is prone to the seal failing and water can get inside and reduce the inefficiency of the pump.

    Good morning
    Your Video just saved my Sunday as I woke up to an E:25 message on our Bosch Dishweasher.
    Using your Video i Found a rubber band entangled around Impeller.
    Thanks from Denmark 🙂

    Hey, what a top video!! Funny clicking noises from a normally near-silent Bosch integrated dishwasher, then some premature beeping and an E25 on the display. Boo hoo!

    Followed the vid and found a small piece of thin wine glass rattling round the impeller. Removed, restarted wash and all’s well.

    Lesson to be learnt here; ban wine and wine glasses and stick to beer cos beer glasses aren’t usually made of such thin glass! Wish me luck on enforcing that ban…

    Hello Paul,

    My mother-in-law was going out to buy a new dishwasher because of the error code on her Bosch dishwasher. Thanks to this video I found a shard of glass in the filter that was blocking the drainage. The dishwasher is all working ok!!
    Thank you, you’ve said us money right before Christmas

    Many thanks. Worked like a charm. Retrieved an elastic band around the impeller plus a little bit of Celery fibre and plastic.
    My wife had thought it would mean a new dishwasher. 5 * award.

    Hi Paul,

    I have a Bosch SMV53A00GB/14 integrated model and noticed that there is water gathering in the lower base area i.e under the sump.
    This is causing the white float to rise which in turn is creating an alarm on the unit. Paul I’m presuming its the sump seal that is leaking as I have ran the unit a few times and cannot see any water dripping or leaking. Any help or advice would be greatly appreciated as this is wrecking my head 🙂

    Hi Paul — I have a Bosch Dishwasher that had the dreaded E:25 error and your how-to video was perfect for resolving my problem! In fact I too had a small piece of glass [just like in your video] that was blocking the impeller. Now my only mystery is that I can’t seem to find the chipped glass. 🙂 Thanks again for the great how-to guide and Happy Holidays to you.
