Here, we will provide a list of common problems with Bosch dishwashers and how to troubleshoot them. Make sure to check all of them.

1) Bosch Dishwasher Fills Up With Clean Water By Itself

Bosch dishwashers are engineered to be more sustainable. But, sometimes, the Bosch dishwasher fills up with clean water by itself when it should be empty.

In the Bosch dishwasher, you can find the water level sensor in the bottom left corner of the door.

If this sensor is wet and dirty, then there will be a problem with the dishwasher filling up with clean water. Cleaning this sensor will solve this problem.

2) Bosch Dishwasher Buttons Not Working

There are many different reasons why buttons on bosch dishwashers might not work.

One of the most common reasons is that there might be a foreign object blocking the button sensors. You can fix this problem by removing the object and then restarting the machine.

If the top buttons on your dishwasher are not working, there is a good chance that the selector knob has gone bad, and you need to replace it.

3) Bosch Dishwasher Fills Up With Dirty Water

Bosch dishwashers offer great quality and functionality, but there may be a few problems that you should know about. One issue is that they tend to fill up with dirty water if the drain pump is defective.

The problem usually lies in a clogged hose or dirty pump filter, which is a common issue.

This is due to a defective drain pump. You can troubleshoot it by cleaning the pump filter and checking the drain hose for any blockages.

4) Bosch Dishwasher Lights Flashing or Blinking

Bosch dishwashers come equipped with various flashing indicators to alert users to potential problems that may need to be addressed.

The flashing light on Bosch dishwashers could be a sign of a serious issue, and you should look into it.

Flashing or blinking lights on Bosch dishwashers are usually signs of an issue with either water flow or electrical power.

The first thing you should do is clean the filter because this can indicate that there is a clog in the drainpipe. You can also try resetting the dishwasher.

To reset, you can press and hold for 10 to 15 seconds all of the buttons on top of the appliance, then press.

5) Bosch Dishwasher Not Draining Properly

Many people find that their bosch dishwasher drains slowly when they open it. The reason for this is not the water level in the dishwasher.

Dishwashers should always be filled with water before running them. But the water does not always have to be all the way up to the top of the machine.

The solution to this problem is to clean out any food that may have been left in your drain.

Make sure there are no kinks or cracks in your drain hose. If you are still having problems, you may need a dishwasher repairman who can figure out what is wrong and fix it for you.

6) Dishwasher Won’t Start

A dishwasher machine uses a motor to turn a pump that moves water and detergent through the machine. Sometimes, these motors can break or bad wiring can also cause damage.

Such problems can cause the dishwasher not to start at all. In this case, you need to call the Bosch help center to properly repair your appliance.

Also, a dishwasher with a faulty door switch or power outlet will not start. Fixing these two components will usually solve the problem.

7) Water Not Filling Up Bosch Dishwasher

The most common reason for water not filling up in a dishwasher is that the hose is kinked or blocked. This can happen when you have higher water pressure, and it pushes the hose out of place.

The solution to this problem is checking your hoses and making sure they are not kinked or blocked. If they are, then try to find a way to move them out of the way so that the water pressure is not forcing them.

8) Dishwasher Making Noise

Dishwashers are a convenient and time-saving appliance. But they can also be a source of frustration if they are not working properly or making noise.

There are many reasons why a dishwasher would make noise. Some are minor, and some are major. Suppose your dishwasher is making a humming or rattling noise. In that case, it could be because the water inlet valve might need replacement or repair.

Usually, dishwashers make noise when they are in use. However, the following factors can cause unnecessary noise:

  • The water is too hot.
  • A load of dishes is unbalanced.
  • There is a leaky seal on the door (the rubber seal that goes around the edge of the door).
  • A bad motor bearing or axle on the motor shaft causing a metal-on-metal vibration when it spins.
  • The filter screen at the bottom of the dishwasher has been clogged with food or other debris and needs to be cleaned out.
  • Faulty insulation between components, such as thermal insulation material preventing heat from escaping from one part to another, leading to higher than normal operating temperatures in one area and lower than optimal performance in the other.

9) Bosch Dishwasher Not Drying Dishes

Sometimes, the Bosch dishwasher is not drying dishes because the water is not getting hot enough. You can solve this problem by adjusting the water temperature to a higher level.

Bosch Dishwasher not drying dishes

There are a few reasons why your dishwasher is not drying the dishes. The first reason is that the dishwasher may not be clean. When a dishwasher is not clean, it can cause dishes to stick to the bottom and not dry off.

If this is the issue, you need to clean the dishwasher properly, and in this way, you can fix this problem.

Another reason for this issue is that the water may not be hot enough. When the water temperature falls below 150 degrees Fahrenheit, it can’t remove grease or food from the dishes as well as when it’s hotter.

If these problems persist, you may need to get your dishwasher repaired or replace it with a new one.

10) Dishwasher Leaking From Motor Area

A dishwasher will leak from the motor area when there is a leak in the pump seal. You can simply fix this issue with a screwdriver and some silicone sealant.

The dishwasher’s pump seal may also leak when there is a defective screw or when the sealant has dried out. This can lead to a dishwasher that leaks from the motor area. However, you can fix this problem with some simple tools and materials.
