Are you tired of staring at your Bosch dishwasher, wondering why it refuses to turn on? You’re not alone! Many homeowners have experienced the frustration of a dishwasher that won’t start, leaving them with a sink full of dirty dishes and a sense of helplessness. But fear not, dear reader, for we’re about to embark on a journey to diagnose and potentially fix the issue.
Power Issues: The Obvious Culprits
Before we dive into the complexities of your Bosch dishwasher’s inner workings, let’s first examine the most obvious reasons why it won’t start.
Electrical Connection
Ensure the dishwasher is properly plugged in and that the outlet is working. It may seem obvious, but double-checking the electrical connection can save you from further troubleshooting woes. Make sure the plug is securely inserted into the outlet, and that the outlet itself is functioning correctly.
Circuit Breaker or Fuse
Check your home’s circuit breaker or fuse box. It’s possible that the breaker has tripped or a fuse has blown, preventing the dishwasher from receiving power. Reset the breaker or replace the fuse as needed.
Dishwasher Door and Latch Issues
A malfunctioning door or latch can prevent your Bosch dishwasher from starting. Let’s investigate these potential problems:
Door Not Closed Properly
Verify that the door is closed and latched correctly. Ensure the door is shut tightly and the latch is engaged. If the door is not closed properly, the dishwasher won’t start as a safety precaution.
Faulty Latch or Switch
Inspect the latch and switch for signs of wear or damage. If the latch or switch is faulty, it can prevent the dishwasher from recognizing the door is closed. Inspect the latch and switch for signs of wear, rust, or corrosion. Clean or replace them as needed.
Child Lock and Other Safety Features
Bosch dishwashers often come equipped with safety features designed to prevent accidental starts or unauthorized access. These features can sometimes hinder the dishwasher’s operation:
Child Lock
Check if the child lock is activated. If the child lock is engaged, the dishwasher won’t start. Consult your user manual or the manufacturer’s instructions to learn how to deactivate the child lock.
Other Safety Features
Consult your user manual or manufacturer’s instructions for specific safety features. Some Bosch dishwashers may have additional safety features, such as a delay start or anti-flood protection. Ensure you understand how these features work and how to bypass or reset them if necessary.
Display and Control Panel Issues
The display and control panel can sometimes malfunction, preventing the dishwasher from starting:
Display Not Working
Check the display for signs of life. If the display is blank or unresponsive, try resetting the dishwasher by unplugging it from the power outlet and plugging it back in. If the issue persists, the display may need to be replaced.
Faulty Control Panel
Inspect the control panel for signs of wear or damage. If the control panel is faulty, it can prevent the dishwasher from receiving input from the user. Inspect the panel for signs of wear, rust, or corrosion. Clean or replace it as needed.
Thermal Issues and Temperature Problems
Thermal issues can cause your Bosch dishwasher to malfunction or refuse to start:
Thermal Cut-Off
Check if the thermal cut-off has tripped. Some Bosch dishwashers come equipped with a thermal cut-off that interrupts power if the dishwasher overheats. If the cut-off has tripped, wait for the dishwasher to cool down before attempting to restart it.
Temperature Sensor Malfunction
Inspect the temperature sensor for signs of wear or damage. A malfunctioning temperature sensor can prevent the dishwasher from starting. Inspect the sensor for signs of wear, rust, or corrosion. Clean or replace it as needed.
Pump and Motor Issues
The pump and motor are critical components of your Bosch dishwasher. If either is malfunctioning, the dishwasher won’t start:
Faulty Pump
Check for signs of pump failure, such as unusual noises or leaks. If the pump is faulty, the dishwasher won’t start. Inspect the pump and its connections for signs of wear, rust, or corrosion. Clean or replace the pump as needed.
Motor Malfunction
Inspect the motor for signs of wear or damage. A malfunctioning motor can prevent the dishwasher from starting. Inspect the motor and its connections for signs of wear, rust, or corrosion. Clean or replace the motor as needed.
Other Possible Causes
While less common, the following issues can still prevent your Bosch dishwasher from starting:
Faulty Detergent Dispenser
Inspect the detergent dispenser for signs of clogging or blockage. A clogged detergent dispenser can prevent the dishwasher from starting. Clean or replace the dispenser as needed.
Wiring or Electrical Issues
Consult a professional if you suspect wiring or electrical issues. If you’ve ruled out the above causes and still can’t find the problem, it’s possible that wiring or electrical issues are to blame. In this case, it’s recommended to consult a professional appliance repair technician.

Q: Why won’t my Bosch dishwasher start, even when I press the Start button?
Sometimes, the issue may not be with the dishwasher itself, but rather with the power supply. Make sure that the dishwasher is properly plugged into a working outlet and that the circuit breaker or fuse hasn’t tripped. Additionally, ensure that the dishwasher is set to the correct cycle and that the delay start feature isn’t activated.
If you’ve checked the power supply and the cycle settings, try consulting your user manual to ensure that you’re following the correct startup procedure. If you’re still having trouble, it’s possible that there’s an issue with the dishwasher’s control panel or the start button itself. In this case, you may need to contact a professional repair technician or the manufacturer’s customer support for further assistance.
Q: Is it possible that a faulty door latch is preventing my Bosch dishwasher from starting?
Yes, a faulty door latch can indeed prevent your Bosch dishwasher from starting. The door latch is a safety feature that ensures the dishwasher doesn’t start if the door isn’t properly closed. If the latch is damaged or faulty, the dishwasher may not be able to detect that the door is closed, which can prevent it from starting. Check the door latch for any signs of wear or damage, and make sure it’s properly engaging when you close the door.
If you suspect that the door latch is the culprit, try cleaning or replacing it to see if that resolves the issue. You can purchase replacement door latches from the manufacturer or a home appliance parts supplier. However, if you’re not comfortable with DIY repairs, it’s always best to consult a professional technician to diagnose and fix the issue.
