Most common repairs needed to fix a Bosch dishwasher
Pump and Motor Assembly Replacement
When a dishwasher is leaking from the bottom, it could have a faulty pump and motor assembly. A bad water seal or crack in the pump housing could be causing water to leak out of the bottom of the dishwasher. As soon as you see a leak, you’ll need to act quickly to prevent damage to kitchen flooring and counters. Schedule a Sears Home Services Repair Technician to visit your home and examine your dishwasher. The technician will replace the pump and motor assembly if it’s the source of the leak.
Water Valve Replacement
A fill valve clogged with debris or deposits can fail to shut properly, causing the dishwasher to overfill and leak water. You may see the dishwasher fill with water in between cycles even when it’s completely off when debris or deposits prevent the water valve from closing completely. Shut off the water supply to the dishwasher and have a Sears Home Services Repair Expert fix your dishwasher if the dishwasher leaks water and clogged water valve isn’t shutting off water properly.
Door Seal Replacement
When a dishwasher is leaking from the bottom, it could have a faulty pump and motor assembly. A bad water seal or crack in the pump housing could be causing water to leak out of the bottom of the dishwasher. As soon as you see a leak, you’ll need to act quickly to prevent damage to kitchen flooring and counters. Schedule a Sears Home Services Repair Technician to visit your home and examine your dishwasher. The technician will replace the pump and motor assembly if it’s the source of the leak.
Why is my Bosch dishwasher leaking from the bottom?
Many leaks from the bottom of the dishwasher tub in a Bosch dishwasher will trip the flood detection safety switch in the base of the appliance below the tub. The drain pump will run constantly even when the dishwasher is off when the flood detection safety switch trips.
Pulling a Bosch dishwasher out from under the counter and accessing the bottom of the dishwasher tub is a complex procedure.
When your Bosch dishwasher leaks from the bottom of the tub and the drain pump runs constantly, shut off the water supply cut-off valve for the dishwasher in case the inlet water system is leaking and schedule dishwasher repair service. We’ll send a Sears Home Services technician to your home to find and fix the leak.
Why is my Bosch dishwasher leaking from the bottom of the door?
A leak from the bottom of the dishwasher door in your Bosch dishwasher typically won’t trigger the flood detection safety switch in the base of the appliance.
When you see water coming from the bottom of your Bosch dishwasher and it still works, check the water seal at the bottom of the dishwasher door (see image below).
Sometimes, you can clean gunk and residue from that seal and prevent the leak.
If the seal is damaged, you’ll need to have it replaced.

Sears Home Services recommendations for a dishwasher that is leaking from bottom
When the dishwasher is leaking from bottom it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.
What to look out for with a dishwasher leaking from bottom diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
When water seeps from the bottom of your Bosch dishwasher, suspect worn gaskets or a cracked sump. Persistent leaks raise your utility costs and risk warping floors. Rather than scrambling for towels after each load, rely on dishwasher technician expertise. Prompt repairs keep your kitchen intact and your Bosch running properly.

Thorough
James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
