Reasons Why Your Bosch Dishwasher May Not Be Turning On
Faulty Door Switch
Your Bosch dishwasher might not turn on if it has a faulty door switch. This switch informs the dishwasher that the door is closed and it’s safe to start a cycle.
If it malfunctions, the machine won’t detect the closed door and won’t start as a precaution. Dishwashers with this problem remain unresponsive when the door is securely closed.
Filter, pump, or hose clogged
In your dishwasher, drain hoses, filters, and pumps play an important role in the drainage system. Bosch dishwashers are programmed to sense residual water from previous cycles.
To prevent clogs, the dishwasher does not initiate a new cycle when standing water is detected. Often, this problem manifests as water that stagnates at the bottom of the dishwasher.
Standing water can develop a musty odor over time, affecting both functionality and cleanliness.
Latch and bracket worn out
The door latch and bracket are essentially what keeps the dishwasher door shut during cycles. These components can become loose or misaligned due to wear and tear or manufacturing defects.
In these cases, the door might appear to be shut, but the latch fails to engage correctly. This will cause the dishwasher to either stop in the middle of a cycle or never start at all.
In addition to making strange noises, dishwashers with faulty latching may make strange sounds.
Power Supply Issues
As straightforward as it may sound, if your Bosch dishwasher isn’t receiving power, it’s not going to turn on. Circuit breakers, wall receptacles, and power cords are all part of the power supply chain.
A failure in any of these components can lead to a completely unresponsive machine. Sometimes it could be as trivial as the plug slightly easing out of the socket.
It could be as serious as a tripped circuit breaker, indicating potential electrical issues in your home.
Control Board Confusion
The control board is essentially the ‘brain’ of your dishwasher, coordinating all its actions. Software glitches or electrical surges can cause this board to become confused, halting all operations.
If you’re experiencing problems with your dishwasher, you might notice that the panel lights are erratic.

Fix a faulty door switch
To resolve a faulty door switch issue, start by unplugging the dishwasher to ensure your safety. You can then locate the door switch, usually situated near the door latch.
You might need to remove some screws or panels to access it. Once located, try adjusting the switch and test if the dishwasher starts.
If the issue persists, consider replacing the door switch with a new one. Make sure to consult your owner’s manual for specific details on how to do this.
Clean the Drain Hose, Filter, and Pump
To tackle a clogged drain hose, filter, or pump, you need to locate these components first. The filter is usually at the bottom of the dishwasher; remove it and clean it under running water.
The hose can be located at the back; disconnect it and rinse it out. It’s best to consult the manual if you suspect the pump needs more disassembly.
After cleaning, reconnect everything and run a test cycle to confirm the issue is resolved.
Replace worn-out latches and brackets
If your door latch and bracket are worn out, the best solution is replacement. You will need to buy parts specific to your Bosch dishwasher model.
Opening the door and finding the latch and bracket, usually near the top of the unit, is the first step. Install the new parts and test the door. Consult your owner’s manual for specific instructions.
Resolve power supply issues
Check that your dishwasher is plugged in properly if you have power supply issues. If the plug looks fine, check your circuit breaker and see if it has tripped.
If it has, reset it. Also, inspect the receptacle and power cord for any signs of damage or wear. If everything seems fine but the problem persists, you might need to consult an electrician.
Reset the control board softly
If your control board is confused, perform a soft reset. To do this, hold down the start button for five seconds with the door closed.
This can often reset the control board and allow your dishwasher to function normally again.
Tips for Regular Maintenance to Prevent Future Problems

Cleaning and lubricating door seals
First, take a microfiber cloth and dampen it with warm water. Gently rub the cloth over the rubber seals around the door. This will remove most dirt and food particles.
For stubborn grime, mix a few drops of mild dish soap in a cup of water. Dip the cloth into this solution and scrub the seals again. Rinse the cloth and wipe off any soap residue.
Assembling the latch
Once the seals are sparkling clean, move on to the latch assembly. Use a silicone-based lubricant. Squeeze a tiny amount on a clean cloth.
Carefully apply the lubricant to the metal parts of the latch assembly. Open and close the door a few times. This spreads the lubricant evenly and ensures a proper seal to prevent leaks.
Pressure Verification Methods
The next step is to check the water supply line pressure. You’ll need a water pressure gauge for this. Attach the gauge to a water faucet close to the dishwasher.
Turn on the faucet and check the reading on the gauge. The ideal water pressure is between 20-120 psi. If the reading falls outside this range, it’s a warning sign.
Using Surge Protectors
Electrical spikes can be a hidden enemy. The best defense is a surge protector. Purchase one with a joule rating of at least 600 for optimal protection. Plug the surge protector into the wall socket first.
Then plug your dishwasher’s power cord into the surge protector. It prevents dangerous spikes in electrical current from damaging the wiring and control board.
Detailed de-scaling of wash arms
Scaling is the enemy of water flow. To combat this, you need to focus on descaling the wash arms and pumps. You can buy a specialized dishwasher descaler or use white vinegar as a natural alternative.
Run a hot water cycle without dishes and fill the dishwasher detergent dispenser with a descaler or vinegar. Do this monthly to keep water flowing freely and prevent any clogs.
Tightly mounting and attaching
A shaky dishwasher can be both loud and ineffective. Securing the mounting and attachments will help. Open the dishwasher door and locate all visible screws and bolts. Use a wrench or a screwdriver to tighten each one until snug.
Don’t overtighten, as that might strip the threads. Make sure to also secure any mounting brackets to the underside of your countertop.
Drying the Control Panel
Last but not least, focus on the control panel. Moisture here can cause rust and electrical issues. If you notice water droplets, take a dry cloth and wipe the area immediately.
Always check the control panel after cycles to ensure it stays dry. Keeping your dishwasher’s control functions clean will protect them from corrosion and short circuits.
