Bosch dishwasher not starting cycle

If your Bosch dishwasher isn’t starting, it could be due to several common issues. These include a faulty door latch or switch, a blown thermal fuse, power supply problems, or a malfunctioning control board. Check that the door is properly latched and that the dishwasher is receiving power. Inspect the thermal fuse, wiring, and control board for potential issues. If these steps don’t resolve the problem, it may be best to consult a professional technician for further diagnosis.

A malfunctioning door latch or switch is a common reason why a Bosch dishwasher won't start. To check if the door latch is the issue, try closing the door firmly and listen for a click. This sound indicates that the latch has engaged. If the door doesn't click or feels loose, the latch or door switch might be defective. In such cases, you’ll need to replace the latch or switch, which is a relatively simple DIY repair.

If the control board is malfunctioning, it may be preventing your Bosch dishwasher from starting its cycle. Signs of a faulty control board include a completely unresponsive display or error codes that don’t clear. Replacing the control board is a more complex repair, typically requiring you to remove the outer panel to access the board. For safety and accuracy, this is often best left to a professional unless you're experienced with electrical repairs. Be sure to replace the control board with an OEM part to ensure proper functionality.

Yes, a clogged drain or blocked filter can prevent your Bosch dishwasher from starting its cycle. If there is standing water inside the dishwasher or if the drain pump is blocked, the appliance may refuse to begin a wash cycle. To fix this, check the drain pump and filter for debris or blockages. Clean them thoroughly to ensure proper drainage, and then try starting the cycle again. Regularly cleaning the filter can help prevent this issue from occurring in the future.
