Troubleshooting Steps
If you’re experiencing a Bosch dishwasher with no lights on the control panel, the first step is to perform some basic troubleshooting. Here are the steps to follow:
- Locate the dishwasher: Before you can check the power supply, you need to locate your dishwasher. Make sure you have enough space to move around it and access the electrical connections.
- Unplug the dishwasher: To ensure your safety, unplug the dishwasher from the electrical outlet.
- Locate the power cord: Look for the power cord that connects the dishwasher to the electrical outlet. This cord should be located at the back of the dishwasher.
- Check the power cord: Ensure that the power cord is properly plugged into the electrical outlet. Check for any signs of damage or fraying on the cord. If the cord appears damaged, it will need to be replaced.
