Standing Water After Wash Program Has Ended
You should find no leftover water inside the dishwasher compartment at the end of your chosen wash program. Thats because the final stage of any wash cycle is to remove all remaining water and push it out through the drain hose.
However, a dishwasher with a problematic drain pump will leave standing water inside the appliance even when it shouldnt. So, if you see that theres a puddle in your dishwasher, you should inspect the drain pump and its electrical connectors.
If there are no clogs and the drain pump is connected as it should be, then youll likely have to replace it with a new one.

Check The Air Gap For Clogs
The most common problem that prevents a Bosch dishwasher from draining is small bits of food caught in the air gap. Luckily, this is very easy to fix.
How it’s supposed to work:
Water is pumped from the dishwasher up through the air gap and then usually down through a larger hose to the garbage disposal. The problem is that when the water hits the top of the air gap, small bits of food can get stuck between the plastic lid and the built-in tube. This prevents the hose from working efficiently so the dishwasher doesn’t completely drain. It’s amazing what a huge problem a tiny bit of food can cause.
If you remove a bunch of debris, the problem is likely solved. Run the dishwasher on the rinse cycle and see if all the water is pumped out. If not, proceed to the next step.

If you can’t find or have misplaced your manual, don’t worry. We can help you find it with our online user manual finder.
Once you’ve removed the screws, and possibly the legs, you should be able to lift the base plate away from the dishwasher. The base plate can have sharp edges, so be careful with your hands whilst you do this.

We had had the worse type of problem with our Bosch Dishwasher, sometimes it works, sometimes not. The pump was replaced 11 months ago when a E24 error popped up intermittently. It continued to show after the new pump. We have cleaned filters, examined water supply, pretty much everything we could find. And by the way, your site is the very best weve seen by way of explanation. We now get an E25 code which suggests the pump but Im not convinced. The salt reservoir is still full requiring no replenishment for months! This is surely wrong, we are in a very hard water area. Have you any idea what might be causing this and how we should proceed?
I have tried to see if I can clean the pump to get rid of error 24, but it has actually triggered it to change to error 25 now. It did the whole cycle when I tested it, but on the last minute of it comes up with an error.
