Most common repairs needed to fix a Bosch dishwasher

Electronic Control Board Replacement

A noisy dishwasher could have a defective electronic control board. The control board manages all functions of the dishwasher. If the control board didn’t send electrical current to the fill valve to fill the dishwasher with water, the pump will make a buzzing noise when its impeller spins with no water in the dishwasher. When you have a noisy dishwasher that makes a buzzing sound, schedule a Sears Home Services Technician to visit your home and check the electronic control board and other components to determine the source of the noise and fix the dishwasher.

User Interface Control Replacement

A noisy dishwasher can have a damaged user interface control. When the electronic control board detects a damaged user interface control, the electronic control board will typically stop the cycle and run the drain pump for several minutes to drain all water out of the dishwasher tub. The drain pump will buzz when all water is pumped out of the dishwasher and the pump continues to run. If you hear a buzzing noise and suspect that the user interface control is damaged, have a Sears Home Services Appliance Technician repair your dishwasher.

Pump and Motor Assembly Replacement

If your dishwasher is noisy and the noise is a buzzing sound, grinding noise or whining sound, then a faulty pump and motor assembly may be causing the noise. A piece of glass or debris rubbing against the pump impeller as it spins can make a buzzing or grinding noise. A worn or failing motor bearing often makes a whining sound. The pump will often continue running for a while even though it's making loud noises but you should have a Sears Home Services Expert check out the pump and motor assembly and replace the part if it’s faulty.

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.

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.
