Why my bosch dishwasher won’t start?
![7 Reasons Why Bosch Dishwasher won't Start [Solution]](https://dishwasherleak.com/wp-content/uploads/2022/03/Bosch-Dishwasher-wont-Start-.jpg)
The Dishwasher not starting problem can be a nightmare for anyone who relies on the Dishwasher to do dishes.
There are different issues responsible for this problem, including Electrical, Water supply, and any other technical problem.
The first thing that you can do is ensure that the Dishwasher is receiving enough power to run the Dishwasher.
Here we have brought a list of issues and solutions that can stop Bosch dishwashers from working.
Electricity issues
If your Bosch dishwasher is not working, then first ensures that your Dishwasher is receiving enough power to start operation.
The Dishwasher requires a stable power supply in order to operate the Dishwasher.
If you have to use additional wire to extend the connection, make sure that the wire is safe and working fine.
After this, ensure that there is no problem with the power source. I recommend you check the lamp or any charger to ensure no problem with the power source.
Solution
If there is no problem with the dishwasher power source, there must be an internal problem with the Bosch dishwasher.
There are two things that you can check inside the Dishwasher. One is a Bosch dishwasher breaker, and another is a thermal fuse.
If the breaker is tripped off, you can run a cycle on your Dishwasher. Sometimes you might have accidentally tripped it by accident.
So, ensure that the breaker is working fine with other devices. If there is a problem, fix it first and try restarting your Dishwasher.
Every Dishwasher has a thermal that prevents any problem associated with short circuits or heating.
When the Dishwasher overheats, it shuts power from the Dishwasher. If this switch blows up, it will prevent the dishwasher from starting.
The switch is located at the bottom of the Dishwasher. If you have a screwdriver and multimeter, follow the below step-wise instruction to inspect the thermal switch on the Bosch dishwasher.
- Turn off the power and water supply on your Dishwasher.
- Remove the Dishwasher if you have kept it in the cabinet.
- Open the dishwasher door, remove all the screws from the Dishwasher, and remove the panel from the Dishwasher.
- Once you remove the panel, unscrew the screw from the control panel if present. If not there, you will see a cylinder-shaped black color switch and wire attached to it.
- Put the multimeter on both sides of the thermal switch. A functional thermal switch shows 0 readings in multimeters. If you are reading 0 in your multimeter, there is no problem with the thermal switch.
Similarly, if the meter shows a higher reading, there must be a problem with the dishwasher thermal switch. I recommend you replace the dishwasher thermal switch in this case.
Door latch issues
The door latch is another issue that is likely to stop dishwasher operation.
The primary function of the dishwasher door latch is to ensure water leakage from the Dishwasher.
The door latch is attached with switches that control the device when the door is opened and closed.
The door switch prevents you from starting the cycle when you’ve opened the dishwasher door.
When you start a dishwasher with an open door, there is a high chance of Water leaking on the various Dishwasher.
Therefore, ensure that the door latch is working fine and there is no problem with its operation.
Solution
It is essential to know Dishwasher only works when the door is closed and the door latch is working fine.
If the dishwasher door latch is working fine, ensure that there should not be any obstacle in the dishwasher door.
The dishwasher switch can stop working when exposed to water for a long time. The switch may become corroded and could stop working.
If the dishwasher door latch is loose, then consider replacing it with one.
Otherwise, check the dishwasher door latch using a multimeter and see if the door switch is working properly or not.
All you need to do is remove the screw and access the door latch from your Dishwasher.
After this, place a multimeter on both sides of the dishwasher switch. If it shows higher reading than recommended power, consider replacing the door latch.
Timer malfunctioning
Sometimes a faulty timer also causes this error in your Dishwasher. The main function of the timer in the Dishwasher is to direct power distribution in the Dishwasher.
A defective timer can cause inadequate distribution of power in the Dishwasher.
You will face the dishwasher operation issue when the dishwasher motor does not receive enough power to start the cycle. This technical problem requires technicians to fix the issue in most cases.
Solution
If the timer is malfunctioning in your Dishwasher, then you should replace the existing timer with a new one.
If you are unable to figure out whether the timer is working or malfunctioning, I recommend you reset the Dishwasher.
Sometimes the glitches can also cause the timer to malfunction in the Dishwasher.
Therefore, it is better to reset the Dishwasher before replacing it with a new one.
Faulty Motor
The faulty motor also prevents the Dishwasher from starting. The motor plays an important role in the Dishwasher.
It circulates water through the spray arms to wash your dirty dishes. Similarly, it also helps you drain dirty water from the Dishwasher.
When the motor malfunction, you can start your Dishwasher even if you have a power dishwasher.
If your Dishwasher was producing a humming sound a bit louder than usual. It is an issue caused by a faulty motor.
When there is some obstacle or blockage in the dishwasher motor, it produces a humming sound.
Solution
If your Dishwasher was producing a humming sound before it stopped working.
There must be a problem with the motor impeller or drain compartment.
The dishwasher motor has two compartments, one for drainage and one for water circulation.
If there is any food or debris build-up inside the dishwasher filter, make sure to clean it.
After cleaning the dishwasher drain filter, try restarting the Dishwasher again.
If the problem persists, you should call dishwasher technicians to fix the issues on your Dishwasher.
Water supply issues
The water supply issue is another major problem that can stop you from starting a dishwasher.
If your Bosch dishwasher is not starting, it is necessary to consider this issue on your Dishwasher.
If your Dishwasher is not receiving adequate water, you may not be able to start the Dishwasher.
The Dishwasher requires water in order to start the cycle in your Dishwasher.
Therefore, I recommend you to make a proper inspection of the dishwasher water supply valve.
If the water is rich in minerals like calcium or potassium, there is a high chance of mineral build-up in the water supply valve.
Similarly, if the dishwasher inlet valve is cracked or kinked, it can also affect water flow in your Dishwasher.
Solution
The solution to the water supply is to ensure proper water flow in the Dishwasher.
If the Dishwasher is not receiving enough water, you can’t operate your Dishwasher.
Therefore, ensure that there should not be calcium build-up in the dishwasher inlet valve.
Spray arms can also build up calcium build-up in the Dishwasher; therefore, make sure to inspect the spray arm of your Dishwasher.
If the inlet valve is cracked, then consider replacing it with a new inlet valve.
Error code
A dishwasher error code can also prevent you from starting the Dishwasher.
If your Dishwasher is showing some kind of error code, consider fixing the error code first, then try restarting the cycle on your Dishwasher.
Error code helps us identify a problem with our Dishwasher.
There are different types of error codes in Bosch dishwashers. Each of these error codes points out various problems in the Dishwasher.

Dishwasher glitches can also stop you from operating the wash cycle.
