    I had the error code E-24. Changed everything, both control boards and hose.Turned out to be the main pump. I think that is the main problem in most cases. Very expensive to repair ($400+). If out of warranty replace the washer.

    I had the same problem. Turned out to be the "air gap" had something stuck in it. Opened up the "air gap" and cleaned it out, problem solved. Some states require "air gaps" some don't. Described here:http://misterfix-it.com/water-coming-out...

    Same here I have had this dishwasher about 6 months. I wish I would known this before I bought it. I am 62 years old and have no means to clean this regularly nor am I going to pay to have someone do this cleaning every few months, thanks Bosch for wasting my money as now I have to buy another dishwasher.

An error 24 code on your Bosch dishwasher means that you have a clog or that your pump is bad. Check and clean out your airgap. If that doesn’t work and your machine is still under warranty, call Bosch. Bosch won’t tell you what the error code means, only that you need a service call, and they will then give you some phone numbers for Bosch authorized appliance repair places, one of which was Mr. Appliance. The appliance repair place will want to put in a new part whether you need it or not so that they can get paid by Bosch. I found this out the hard way. Hey Bosch, be smart and tell your customers what the error codes mean so that they are informed and you don’t look like you are trying to rip them off. Leave that to Mr. Appliance. You can always remind the customer that working on the actual dishwasher voids the warranty. It doesn’t take a rocket scientist to figure out how to clean out the airgap, which isn’t a part of the dishwasher, but rather part of your plumbing connected to the dishwasher. I suspected this to begin with, but because you told me I needed a service call, I had to assume it was beyond basic owner maintenance. Great way for you to flush money down the toilet and look bad doing so.

    I have done Bosch Warranty service for over 20 years.
    I can assure Bosch does not require that we replace a part in order to get paid.

    I cleared the blockage and reset the timer - works fine. Thx for this site and advice

  • roofus_143 May 07, 2011

    How did you "Clear the timer"? By powering off the unit? I added to pitchers of water, started a cycle, i can hear the pump, it drains the water, I can also hear the water draining through the sink drains, about 2 or 3 minutes into the cycle, BAM! E:24! Any other ideas?

After reading the solutions on this page I removed the screen and tried the plunger with no results. This will/could work on a less serious clog in the drain line. IT JUS MAKES GOOD SENSE TO TRY THE PLUNGER FIRST. Since the plunger did not work I tried the air method. I disconnected the dishwasher drain line at the sink drain connection located under the sink and tried (like a big dummy) blowing in to it with my mouth trying to remove the clog with no positive outcome. At that point I thought to myself, I Sure Wish I Owned A Air Compressor to get a little compressed air in to the line to assist in jarring loose whatever is caught in the drain. As soon as I had this thought I remembered that I had a can of compressed Air 3M Dust Remover in the garage that would possibly work. I retrieved the can of air and placed the 1/16th inch x 6 inch plastic spray nozzle (supplied with the can of air for getting in to hard to reach places) in to the end of the dishwasher drain line where it makes connection to the sink drain. After placing this small diameter spray nozzle in to the end of the drain line I inserted my finger in the drain line around the small air can spray nozzle forming a air tight seal and pulled the trigger on the can of air. Within 5 seconds of pulling the trigger on the air can the water in the bottom of the dishwasher started bubbling indicating that the clog was free. This was about a 10 cent repair procedure verses a $130.00 repair tech call. This is a very easy procedure.

I had the same problem on my bosch dishwasher, read all the web solutions and was no better off. Tried this simple solution; disconnected the water outlet hose from the discharge end, ie where it connected to the plumbing outlet, not the dishwasher itself and simply blew back into the dishwasher. There was resistance at first then I could blow easily, clearing whatever was blocking, after that it worked fine. Of course it could be the pump or impeller, whatever, but this is a real good place to start as the problem is related to draining, its a quick and easy test.

Water was sitting in the bottom of the washer with code E24. Blowing in the drain hose did nothing for me, the system was closed, resistance was total, back flow valve maybe. I took the drain basket and screen out, then used a toilet plunger. Blockage is gone and the machine is running again. Thank you for cluing me into the problem!

I was almost ready to bin my 1 year old dishwasher because of the e 24 error....then my husband discovered a simple solution.....after a minute of starting the dishwasher switch off the power and restart immediately. So if the cycle starts at 2hrs 30 minutes stop at 2 29 and immediately restart. Works every single time

    Thank you for this tip! Yes, seems to work fine each time now when doing this. I also tried all the other recommended things to do which others have mentioned on this thread and I'm convinced it's an electric fault as this issue (E24) only really started to regularly happen and then consistently happen after the mains electric circuit breaker was switched off a few times. Had engineer out who said they 'reset' the electrics on it and that should sort it but it didn't. Thanks again! For the time being this solution is saving us hours of washing up time and time messing around ourselves trying to nut out the issue and call out costs with engineers.

    Yes it does work- has been working for me last 2 years. Also found a little easier fix- when the first minute is over just open the door and close it again ( without switching off the machine). Have been doing this the last 6 months and works brilliantly. Thanks for your response

I had E24 on my Bosch just installed over a year, then I replaced water sensor, Power controller board (on the bottom of the tub), and inlet valve. None of those helped. I open the Air Gap valve on top the sink, and it was blocked with bean sprouts, small green stuff....
I clean it with a shop vac, then problem went away. I hope this help.

We've had the same problem on and off for a while now. Up until yesterday we've solved it by emptying the drain - sometimes once or twice before it would start. Now that doesn't solve it anymore soe and so we've just pulled it out of position and dismantled the sides. That allows us to see that there is p l e n t y or grease stuck in on of the plastic pipes. Whatever your problem solution it's good to see what happens inside the dishwasher - so that's a tip.
We've yet to figure out how to dissolve it. Just blowing into the pipe does nothing. Completely clogged shut. As we are 8 in our family and the machine is 8y, we're not going to call for a repair man. Either we fix this or we're getting a new one.
Thanks for all the helpful information here.

E24 fault could be one of the following, Kinked outlet pipe, foreign object stuck in the heat pump/circulation or partially seized. White plastic cover missing/ not fitted correctly over pump.
If your appliance is within two years, Bosch will send out one of their engineers!

I didn’t see the answer here but maybe someone else posted it earlier but I’ll post my solution. I tried everything, my dishwasher has a new computer new drain pump and new filters drain hose is totally clear. The quick fix of opening during the start up has worked but I’m somewhat of a perfectionist and I like troubleshooting hints so I finally got some time to dig into it. After doing everything above, I finally just ran a couple cycles while holding the drain tube and this is what I found! In between the drain hose and the pump there is a white connector that connects the drain hose to it, inside of that there is a back flow prevention valve that looks like the plastic piece inside of a soda bottle cap. This piece was still intact but it had become old and weak and weight of the water will slightly push back on it and open it so that water flows back into the pump area. Even though it’s not a lot, it’s enough to cause the pump to think it’s not draining. It takes about 5 mins to replace and costs $11.00 on Bosch website. If anyone would like pics or video let me know. Solved it for me when nothing else would.

The E24 error code means that the drain water system is broken. The manufacturer informs that the problem is caused by the drain hose bent or its clogging.

Mine happens in really cold weather... like below -20C outside. As the drain hose is on the back against an outside wall and the dishwasher body and door insulate that space from the warm kitchen, it can freeze. I open the door and allowed the warm kitchen air to get at the inside of the dishwasher. 6-8 hours later it is resolved. When i know it is going to be really cold overnight i premptively leave the dishwasher door open overnight to prevent this problem.

Definitely check the air trap, especially if your washer is newer. That fixed mine. The air trap is the little dome on top of the sink next to the sprayer. Look for food trapped in the tube inside. Also clean the fine filter in the floor of the washer tub as described before.

After a kitchen remodel we got this E24 error. The knockout plug in the garbage disposal's dishwasher connection was never removed. So, the E24 error can mean that there is a blockage in the drain pipe.

Same error code. Disconnected hose and attached shop-vac, using a damp towel to seal up the connection. Flipped it on and it ran for a second or two before whatever was causing the blockage came loose. Running fine now.

After trying everything, the thing that finally works for us is starting the dishwasher, waiting until it counts down one minute (usually from 2:05 to 2:04) and opening the door, pushing back the switch just inside the door, and restarting it. For months now, we haven't had a problem as long as we start it this way.

I've found an infallible way (so far, anyway) of fixing the e:24 error. Turn the dishwasher on, then push the start button for about 3-4 seconds until the display reads "0:01." Close the door and within a minute you'll hear the water draining out from the bottom. So far this has worked every time for me.

First of all thank you for this forum... This thread probably saved me a few hundred dollars!

So I have a Bosch dishwasher and a E:24 code shows up. Drained the water in the tub with a turkey baster. Cleaned the filters and made sure the pump orafice was clear and that the pump was able to spin. Found an unpopped popcorn kernel and some zuchinni and orange peels... (Thank you wife) Thinking I fixed the problem, I let it run... Still nothing and still got the E:24 code.

Took a break and then decided to check the air gap. Pulled off the metal top and unscrewed the plastic cap. Found some organic debris... But more importantly a piece of plastic, right there at the top of the air gap tip. It was the heavy duty food packaging type plastic about 1/4x1" long. Ran the dishwasher... and VOILA! Damn thing works!

Thanks again fixya! I would have felt pretty silly having to call a plumber or Appliance repair for a simple piece of plastic!

I turned the dishwasher off and then tried running the wash cycle again after getting the E24 error. It continued getting the error. I did check all the drain lines and couldn't find anything that could have clogged the drain. Note that you can not force water or air through the pump unless the pump is on. When I pulled the washer out from the cabinet to work on it I unplugged it. Eventually I plugged it back in and it worked fine. I suspect that unplugging it just allowed the error code to reset. You might just try turning the circuit breaker off then on again, and see if that works. It's hard to say what actually cleared the error.

This seems to happen to us most often when it is really cold outside (below 0 F). We need to wait until a bit later in the day, when it's warmed up a bit and the sun has had a chance to beat on that part of the wall, etc., before running a cycle. First time it happened, we had a repairman come in and he also suggested running the hot water in the sink for a few minutes before starting a cycle.

I just solved this problem with my 3 month old Bosch dishwasher. The dishwasher was throwing both E:24 and "water tap" messages.

While I wanted to blame the dishwasher itself for the problem, it turned out that a pistachio shell was stuck in the drain tube that fed the airgap in my setup. The airgap is a separate assembly. The shell might have been there since the previous dishwasher. Once removed, all problems gone. Faith restored in Bosch.

Not sure why the "water tap" error was appearing for a drain issue, but I'm happy the problem is solved.

Hope that helps.

You are all absolute Champions, this problem has been driving me nuts for the last couple of weeks.
I have shook it, tilted it, cleaned every nook and cranny.
It was emptying into a bucket fine, so the last resort was blowing into the outlet hose and pouring boiling water into it's innards before I removed the monster completely.
I also put a bit of cleaner (creme cleanser) in it as well to help remove any internal build up of grease. Will also run some bicarb and vinegar through it to help clean and break up anything organic that might still be lurking.

Shows error 24 on my dishwasher Bosch


Possible causes for the E24 error code:
The drain hose could be blocked
The dishwasher filter may need to be cleaned
Brand new garbage disposal. The installer may have forgotten to remove the 'knockout' plug
After fixing the problem, reset the dishwasher according to the owner's manual

What does E24 displayed when wash cycle finished mean


Check the filter and drain pump.

Bosch dishwasher E24 error code The error code E24 on Bosch dishwashers is a drain error code although it can be triggered by the circulation pump or main control issue. The first thing to check is your drain system, make sure the filters are not plugged and the check valve is in place. Your check valve is located in the bottom of your tub on the side wall, generally white in color. If those two things are looking good check your drain hose is it kinked or clogged? (Did you just replace your garbage disposal, if you answered yes, remove the plastic plug that comes on the new disposal.)
The next thing to check is your drain pump, when you press cancel can you hear a humming noise? If not you will need to check for power to the drain pump, there should be 120v. If all the items in your drain system test OK and you are still getting the code the next step will require you to remove the dishwasher from the cabinet.
After the dishwasher has been removed from the cabinet you will need to get to the main control on the lower right side. Make sure the breaker is turned off to the dishwasher at this time. Remove the connector with the three grey and three black wires. Your looking for 89 Ohms on the grey wires going to the drain pump, and 14 Ohms across the black wires going to the circulation pump. If those both check out you will need to replaced the main control.
( Just a quick update if your wash motor is not working properly this will also make the code come up. If the brushes in the motor get old this will cause the motor to drag and that's what triggers the error code.) Hope this helps!!!

I have a Bosch dishwasher that had error code E24. DW would work if door was opened about 1 minute into washing. New drain pump. No fix. New error code of E21. New control unit, still same problem.


E21 is a circ pump blockage issue. Check that all hoses are clear, unit drains completely. Depending on the age, a new circulating pump may be needed or new motor capacitor.
