Most common repairs needed to fix a Bosch dishwasher

Pump and Motor Assembly Replacement

A dishwasher that is leaking 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.

Electronic Control Board Replacement

A leaking dishwasher could have a defective control board. The control board sends electrical current to the water fill valve to fill the dishwasher. If the electronic control board doesn’t shut off the current supply to the fill valve properly, the dishwasher could overfill and begin leaking. When you see your dishwasher leaking, schedule a Sears Home Services Repair Expert to visit your home and find the source of the leak. The technician will replace the electronic control board if it’s defective.

Door Seal Replacement

When you find your dishwasher leaking, you can suspect that a worn or damaged door seal is causing the problem. The rubber gasket that surrounds the tub opening keeps water from leaking out of the dishwasher when the door is shut. A worn or damaged seal will allow water to leak through the edges of the door. When you discover a dishwasher leak, have a Sears Home Services Technician visit your home and replace the door seal if it’s leaking.

How is the leaking problem fixed?

Correcting most leaking problems usually involves replacing the pump and motor assembly, electronic control board or door seal. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a dishwasher that is leaking

When the dishwasher is leaking 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 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.

Troubleshooting a Bosch Dishwasher Leaking from the Door

Check the door seal when you see your Bosch dishwasher leaking from the door. Adjust the dishwasher door seal if it’s misaligned. Replace the door seal if it is damaged.

Examine the door latch assembly to see if it is holding the door tightly shut. Adjust or replace the door latch assembly if it is damaged and causing your Bosch dishwasher to leak from the door.

If these troubleshooting tips don’t help, have a Sears Home Services technician visit your home and fix the problem causing your Bosch dishwasher to leak from the door.

Fixing a Bosch Dishwasher Leaking at the Bottom of the Door

Water leaks at the bottom of the door in a Bosch dishwasher are often caused by a blocked, cracked or clogged spray arm. Check the condition of the spray arms and clear any clogged spray holes. Make sure not items are blocking spray arms when loading the dishwasher.

Replace a spray arm if it’s cracked or damaged.

If you’re unable to find and fix the cause of your Bosch dishwasher leaking at the bottom of the door, have a Sears Home Services technician visit your home and repair the problem.

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.
