Bosch dishwasher is not turning on

The most common problem people complain about is the bosch dishwasher not turning on. There are a lot of reasons for this problem.

First, check whether the dishwasher is plugged correctly into the socket or not.

Sometimes, in a hurry, you do not plug in the power cord in the wall outlet. So, first, check whether the cord is inserted accurately or not.

Inspect the power supply in the home; sometimes, you don’t know if the electricity is not present or if the other lights are turned on.

Confirm the power supply in the kitchen from the main circuit box because the circuit breaker trips due to the wall socket in the kitchen.

Next, see the power cord because if you keep it tangling or twisting, it will damage the cable, and the bosch dishwasher will not turn on.

If you see the power cord is damaged, replace the cord to turn on the appliance.

In some brands, the unit does not turn on if the dishwasher door remains open, so check if it is closed before you load the plates.

If still the unit is not switching on, it may have an issue with the main control panel.

You can hire a skillful person to open the dishwasher and troubleshoot the control panel.

Dishwasher not draining water properly

The next main issue is the bosch dishwasher not draining the water properly due to a drain issue.

When you finish dinner and want to clean the dishes in the dishwasher, remove the remaining food from the dishes.

Because when you put the dishes into the dishwasher shelves without removing the food, this small food debris is stuck in the drain hose and clogs the pipe.

So, put the dishes in the dishwasher after clearing the remaining food and other debris.

One more reason responsible for water in the dishwasher base is overloading the unit with dishes.

Overloading the dishwasher shelves with extra pots will make it difficult for water to clear from the base due to the filter being clogged.

Always put fewer bowls in the dishwasher for one clean cycle because if you put more dishes, you will have to increase the rinse aid, producing more sud in the unit.

Extra sud is stuck in the pump impeller, making it hard for the pump to clear the water flow and sometimes damaging the motor.

The last reason for the water drainage issue in the bosch dishwasher is a blockage in the sewerage line due to wastes and sediments present in the water.

You can clear the water clog in the drain hose and sewage pipe by making a hot water solution with baking soda or vinegar.

Now run this solution in the dishwasher and wait for half an hour. After half an hour, pour fresh water into the unit; you will see all the clog is cleared, and water flows easily from the dishwasher base.

Drain pump is faulty

Not washing the dishes accurately

If the bosch dishwasher is not washing the dishes accurately, then the most common reasons behind this trouble are dirty water, rinse aid and extra sud.

First, check the water level in the dishwasher because if there is less water in the dishwasher tub, then the plates and spoons will not wash properly.

Extra sud is not suitable for the dishwasher because it is stuck on various parts and affects the efficiency of the bosch dishwasher.

The dishwasher does not clean the plates efficiently in areas with increased sediments in the underground water. Dirty water is also the main culprit beyond the dirty plates.

Water not filling in the dishwasher

Water not filling in the bosch dishwasher is also one of the most common problems. If there is no water coming into the unit, check the water supply or water in the main tank.

The clean water valve may be shut off, so check it, and if it is shut off, turn its position so that the water starts to flow in the appliance.

The number of minerals present in the freshwater makes it hard water that affects a lot of the working of the electric appliances in the home.

If more minerals or sediments are in the water, they will get stuck in the hoses and clog the pipes. So, clear the clog from water inlet hoses and try to use to filter water in the bosch dishwasher for the clean cycle.

Buttons not working

In modern dishwashers, the indicator light starts flashing when any part of the unit becomes faulty.

Every problem has its color light or error codes. In old models, it was challenging to identify which part was the culprit if the dishwasher was not turning on or the water was not draining.

However, it is easy for the user to identify the main problem after watching the indicator light flashing.

Usually, a vent motor, vent, and heating system are used to dry the pots and bowls in the bosch dishwasher. First, check if the vent is necessary for it to open properly; if it is not opening, replace the vent in the appliance.
