Most common repairs needed to fix a Bosch dishwasher
Electronic Control Board Replacement
When your dishwasher is not starting a cycle, a defective electronic control board could be causing the problem. The control board will freeze up and fail to start a cycle 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 start a cycle. Determining whether a control board is defective is difficult. Have a Sears Home Services technician diagnose and repair your dishwasher when it won’t start a cycle.
User Interface Control Replacement
When your dishwasher is not starting, 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 start key on the user interface control can prevent the dishwasher from beginning the cycle. Also, a stuck key on the user interface control can cause the electronic control board to stop all dishwasher operations 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.
Wire Connector Replacement
When your dishwasher is not starting, a stripped wire connector between the user interface control and electronic control board could be causing the problem. The wire harness between the electronic control board and user interface control must also stay connected to keep the dishwasher working. The control board will stop the dishwasher and keep it from starting when that wire harness is damaged or disconnected. When your dishwasher isn’t working, have a Sears Home Services Repair Expert visit your home and fix the problem.
What to expect when you experience a Bosch dishwasher not starting issue
How is the not starting problem fixed?
Correcting most not starting problems usually involves replacing the electronic control board, user interface control or wire connector. 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 not starting
When the dishwasher is not starting 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 not starting 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 that Will Not Start
When your Bosch dishwasher will not start, check the dishwasher door to make sure it is closing properly. Push in firmly on the top of the dishwasher door to make sure the door latch fully engages the door catch and the door switch senses that the dishwasher door is shut.
Check to see if the child lock is engaged on the control panel. Shut off the child lock feature if you find it enabled.
If these tips don’t help fix your Bosch dishwasher that will not start, try resetting the electronic control board. Completely shut off electrical power to the dishwasher so the electronic control board will reboot and go back to its default settings.
To shut off power to the Bosch dishwasher and reset the control so the dishwasher will start, flip the light switch beside the garbage disposal light switch next to the sink if you have that switch installed. That switch will completely shut off power to the dishwasher. Leave the switch off for 2 minutes and then turn it back on to restore power.
If your Bosch dishwasher does not have that switch installed, you can unplug the dishwasher or shut off the house circuit breaker for the dishwasher to completely disconnect power for 2 minutes.
If the Bosch dishwasher will not start after resetting the electronic control board, schedule dishwasher repair services and we’ll send a Sears Home Services technician to diagnose and fix the issue.
A Bosch dishwasher that won’t launch a cycle might have a misfiring latch switch or a defective control module. This leaves each load unwashed and wastes detergent. For a rapid fix, trust dishwasher service near me. Getting the cycle started again means your Bosch can quickly tackle the day’s dish load.

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.
