Bosch Dishwasher E 25 Error Message

This is a completely non-medical post that will be of no interest to 99% of the regular readers of this blog (maybe a little interest if you want to see how I fixed my dishwasher), but I wanted to put it up for the search engines to help anyone try to fix had the same problem that ate up a few hours of my day.

When our previous dishwasher died on us last year, we spent a little more money on a Bosch dishwasher. So far, haven’t had too many complaints about it. On the pro side, it is quiet and it gets the dishes quite clean. There also isn’t a water jet spinning around above the top rack, so you can fit larger items up there. On the con side, there isn’t as much space for plates on the bottom. We have trouble fitting a day’s worth of dishes from our 6 person family inside. And there’s no way you’ll get a large pan in there unless you take up the whole upper rack. So I wouldn’t recommend a Bosch dishwasher for a larger family.
The warranty on our dishwasher was for 12 months. Unfortunately, a problem developed at 15 months. Every time the dishwasher started up, it would run for a little while, then it would stop and flash an “E:25″ error message.
Mrs. WhiteCoat called the service line. The “E:25″ code meant that there was an outflow blockage of some sort. For a minimum $125 charge (not including parts and labor) they could send a technician out in about 5 days.
I like working with cars and other mechanical things, so when I got home from work, I figured that I would take the dishwasher apart and see if I could figure out what was wrong.
I pulled apart the drainage apparatus from inside the dishwasher. There was a lot of sludge and debris there. That could be blocking the flow of water. Mental note to clean that stuff out more often. Cleaned everything out and reassembled the drainage apparatus and started the dishwasher. Still got the same error message.
So I *turned off the electricity to the dishwasher at the breaker box first*, then I pulled the dishwasher out from under the counter. In the pictures, the dishwasher is laying on its right side. I removed the clamp on the drainage hose and let the water inside drain into a plastic bowl. Then I tried blowing through the drainage hose, figuring that if there was a blockage between the hose and the sink, I wouldn’t be able to blow air through it. Air went through the hose fine. I put my hand around the edge of the hose so I wasn’t getting slime in my mouth and it still didn’t taste very good, but air went through the hose fine. So I knew that the problem was with the drainage motor or the impeller.
I pulled off the drainage motor by prying up a couple of clamps on the side and twisting the housing. Inside, I found the problem. There was a chip from a piece of a plate stuck in the drain.
I pulled out the chip, reassembled the drainage motor assembly, turned back on the electricity, and ran the dishwasher through a cycle. No more error message. The chip from the plate was too large to pass through the drainage pipe and was either causing the water to back up or it was blocking the impeller and keeping it from spinning.
Hopefully this little description helps someone else out there. If so, please leave a comment in the comment section.

  1. I had the same error on day 2 of use of my brand new Bosch washer. Cleaned out the trap, where “somehow” a piece of chicken had become lodged. Worked just fine afterwards. Re-iterated need to clean large debris from dishes with family meeting…

  2. For me, this reiterates the need to not be penny-wise pound foolish.

    Get a dish washer with an on-board macerator.

  3. This is the best post out of all the DIY and “How to” websites for information on how to fix this error message. You just saved me $110 on a service call with your great pictures. Quit medicine and do online appliance repair tutorials.

  4. Worked like a charm… pulled a piece of glass out of the impeller. Thanks for the great advice – I probably would have just bought a new washer!

  5. My Bosch dishwasher model # she3arf5uc came up with error code 24. checked all the how do it web sites and this was a great help. I took the drain hose off under the sink, took the filters off in the bottom of the machine, removed the impeller cover, took my air compressor and blew air back to the dishwasher. I left water in the washer so I knew the line was free from the sound of bubbles. put everything back and works fine. I live in a small town and a service call is more money to drive out here…..got to love the internet.

  6. Many thanks. I removed the front kick panel and I was able to reach underneath and disengage the drain motor as you described, without having to disconnect and pull the dishwasher out. And after some hunting around I found a piece of clear glass.

    Before I went that far I followed the steps in the Bosch service video http://www.youtube.com/watch?v=hfw3vliCf4c. This allows you to clear the impeller from accessing the tub of the dishwasher. However, I could not see the piece of glass to remove it like in the video. I even went in with some long nose pliers hoping I could find the problem.

    So in the end, your video was a huge timesaver.

    • I reported earlier that removing a piece of glass from the drain pump solved my problem. It wasn’t the entire problem. The dishwasher worked intermittently. Sometimes it would get through a shorter wash cycle and sometimes the E25 error would return. But I couldn’t find an object like a piece of glass that was interfering with the pump.
      Also, during the wash cycle when it came time to drain the tub, I could hear the pump start then stop one or two times. It would either then drain or give me the dreaded e25 error.
      Finally, I removed the drain pump and disconnected the power cable to it. On close inspection, I noticed something tightly wrapped around the axle between the impeller and the motor -even though the impeller was still moveable. I cut through the stuff with a knife (it was a piece of an elastic band from vegetables or meat or something that made its way past the screen).
      Once that was removed, I reinstalled the motor and so far the dishwasher is operational.
      My theory is that the elastic junk was impeding the motor enough (but intermittently) to send feedback to the controller board that there was a blockage. We’ll see. If you don’t hear from me again, then that was it.

      Sorry to mess up your medical blog with this, but it was the best collection of info on the E25 topic. Bocsh’s site and manual was worthless for this.

      • You’re definitely not messing up my blog. I made the post to help other people with the same problem.
        Sounds like the piece of plastic was tamping down on the impeller speed and having an adverse effect on the flow of water. Good for you for picking up on it. I’m not sure I would have even caught that one.
        I’m glad to hear the post helped you out.

    • Thank you so much. I’ll a single Mum but always willing to give it a go, especially if it saves me a dollar, worked a treat. Although I do agree with the voice over, I cut my thumb on a glass that was blocking the pump.

  7. Thank you so much for posting this! We just bought the dishwasher in January, so didn’t think it could be a mechanical problem. I was able to vacuum one out after elevating and balancing it on the edge of the drain. The other chip was lodged in the impeller. I dislodged it but then couldn’t find it. We had to keep running the Rinse cycle to see if it would drain. I had to bail out the dishwasher 5 times before final success. I am amazed that (1) Bosch doesn’t include the error numbers in their documentation, (2) the diagram showing you how to remove the pump cover is TERRIBLE, and (3) the installer mentioned nothing about this potential problem. This is the first Bosch I’ve had and the first dishwasher I’ve had with this filter style, so it never entered my mind when my husband broke a vase trying to take it out of the dishwasher that it could lead to a problem. The breakage was at least a couple of weeks before the blockage. Next time we break something, I will vacuum thoroughly before running the dishwasher. Ditto for any chipped dishes. Thanks again!

  8. Your post was a godsend. It was a piece of glass. Thank you.

  9. Well our Bosch started grinding yesterday and showed the E:25 error code only 9 months since purchased. I followed your instructions and found no chips or bones everything was clean and looked new. I used my wet vac to suction out the drain lines. Put it back together since I pulled it out and flipped upside down to work on it. It’s working fine but the feet reset, I had the hardest time getting the unit level as i’m not sure how to level the inboard feet without taking the unit back out.

  10. Thanks for doing this. Comments very helpful too, especially one that suggested the Bosch youtube video about clearing the impeller. It worked!
