Most common repairs needed to fix a Bosch dishwasher
Electronic Control Board Replacement
A dishwasher that won’t turn on could have a defective electronic control board. The control board will freeze up and fail to power up the control panel when its internal memory and logic is corrupted. A failed internal electronic relay or bad electronic part on the circuit board could be causing the control board to freeze up and not continue working properly. Determining whether a control board is defective is difficult. Have a Sears Home Services technician diagnose and repair your dishwasher when it won’t turn on.
User Interface Control Replacement
When your dishwasher is not turning on, a damaged user interface control could be causing the problem. The user interface control connects to the electronic control board through a wire harness and sends signals to the control board to help control the dishwashing cycle. A bad power key on the user interface control can prevent the dishwasher from powering up. Also, a stuck key on the user interface control can cause the electronic control board to stop the cycle and the dishwasher won’t work until the damaged user interface control is fixed. Have a Sears Home Services Repair Expert visit your home and replace the user interface control if it’s damaged.
Power Supply Board Replacement
When your dishwasher is not turning on, a damaged power supply board could be causing the problem. The power cord connects directly to the power supply board and the power supply board sends power to the electronic control board to power up and operate the dishwasher. When your dishwasher is completely dead and it is getting power through the power cord, you’ll need to have a Sears Home Services Technician check out the power supply board and replace it if it’s damaged.

Follow your Bosch owner’s manual troubleshooting tips
First, follow the troubleshooting tips provided in the owner’s manual for your Bosch dishwasher (shown above).
Check the dishwasher power supply
If your Bosch dishwasher has a power cord that plugs into an electrical outlet under your kitchen sink, make sure the power cord is fully plugged in. If it is, check the outlet for electrical power by plugging in a night light or other small electrical item into the outlet. If the night light works, you know that the outlet has electrical power.
If the electrical outlet is dead, reset the house circuit breaker for that outlet and test it again. If the outlet is still dead after resetting the house circuit breaker, have an electrician repair that electrical outlet.
If the outlet works after resetting the breaker, plug the dishwasher back in to see if it powers up. If it does, then you’ve fixed the problem.
If the power cord going to your Bosch dishwasher is hard wired to the junction box, reset the house circuit breaker if it’s tripped. If the dishwasher won’t power up after resetting the house circuit breaker, schedule dishwasher repair service to have a technician examine and repair your Bosch dishwasher.
Check that the door is closing and engaging the door latch properly
Push in firmly on the dishwasher door to make sure that it is fully shut.
If you don’t hear a click indicating that the door strike is engaging the latch properly, then you’ll likely need to schedule service to have the door and/or door latch repaired.

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.
Zero power in your Bosch dishwasher often involves a tripped fuse or dead electronic board. Flicking the breaker isn’t enough if the core component has fried. Instead of losing automatic dish duty, let a dishwasher repair near me expert investigate. Restoring power keeps your cleanups on schedule.

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.
