A Bosch Dishwasher Error Code E09 Is a Heating Element Problem

If you see this error code on your dishwasher, this is an indication that something is wrong with the heating element. There is a good chance that the heating element has been burnt. Therefore, it might need to be replaced. On the other hand, it could be an electrical problem, causing the heating element to have issues.

The heater is an important part of the circulation pump. Unfortunately, you may not be able to find it separately in order to replace it. You need to think about the possible reasons why this might have happened.

Issues with the Heating Element

There are a few possible reasons why you might be seeing this error code with your heating element.

For example, there could be an issue with the wiring. If there is something wrong with the wiring of the heating element, it may not be functioning properly, leading to the error code.
Or, there could be an issue with the temperature sensor. If the temperature sensor is not working properly, the heating element may not know when to turn on or turn off. This can lead to the error code you see.
There could also be a problem with the main module. If the main module is not working appropriately, this can trigger an error code as well.

You should think about these problems, as they could be causing your dishwasher to malfunction.

What Causes the Heating Element To Malfunction?

Now that we understand the various issues that could develop with the heating element, it is time to take a look at the possible causes. These include:

P.S. In case you are experiencing different errors on your Bosch dishwasher, feel free to check our other guides below:

The Water Is Leaking from the Heating Element

One of the first issues that could be developing with your dishwasher is that water is leaking from the heating element. Over time, the seals and gaskets in the appliance are going to wear out. This could cause leaking to occur.

As a result, water could begin to coat the heater and motor. This causes the body to lose its tightness. This could also cause the heating element malfunction, leading to problems.

There Is a Clogged Filter Present

You may also notice that there is a clogged filter. If the filter is clogged, water is not going to be able to drain appropriately. This could cause the heater to overheat.

Fortunately, this is something that you may be able to fix. If you can spot the mesh filter, you may be able to unclog it, fixing the problem.

You Are Using Hard Water

If you do not have high-quality water, this could also impact the operation of the dishwasher. If you are using hard water, there is a lot of scales that could take place. This can lead to a thick layer, forcing the heating element to work harder.

Eventually, the heating element is going to overheat and burn, leading to problems. You may need to take steps to reduce the appearance of scale.

Voltage Issues

Finally, you may also want to take a look at wiring and voltage issues. If you do not have a voltage regulator connected to the dishwasher, and there is a problem with the power grid, this could cause the heating element to burn. This can also cause an E09 error code to appear.

Dealing with a Bosch Dishwasher Error Code E09

If you are wondering how to fix this malfunction, the first thing to do is to make sure the error code is legitimate. Therefore, we need to start by resetting the program.

To do this, you should remove the plug from the socket. Then, you should wait 10 to 15 minutes for the system to reset. After this, reconnect the dishwasher to the power supply and see what happens.

If the error code is no longer on the screen, you have already solved the issue. If the error code E09 shows up again, then it is time to take a closer look at the heating element. There are several steps you will need to follow.

To address an error code E09, you should:

Start by unplugging the dishwasher once again. You also need to unplug the dishwasher from the water supply, sewage system, and other utilities that could be present in the building.
Next, you need to remove the plastic clips that are located at the edge of the dishwasher itself. They should not be that hard to unclip. Simply remove them to release the dishwasher.
Next, you need to remove the screws in the front part of the equipment to release it. That way, you will be able to access the entirety of the dishwasher.
If your Bosch dishwasher has thermal insulation, you will need to remove this as well. That way, it does not get damaged during the process.
Once you have done all of this, you can open up the tub door. Pull out all of the racks. You should also remove the spray arm as well as the filter. If your filter has mesh in it, you need to remove this as well.
There are probably several screws that are responsible for holding the circulation pump in place. You need to unscrew them and remove this as well.
After you are done doing this, you need to unscrew the sump. Make sure you remove this to access the heating element.
You need to remove everything that is responsible for holding the circulation unit in place. This includes wires, hoses, and nozzles. After this, you should be able to remove the heating element.

Is the Heating Element Broken?

The next thing you need to do is take a look at the heating element to see if it is broken. If you have a multimeter, now is the time to pull it out. Check the resistance of the heating element and see if it is still active. If you are getting good readings on the multimeter, the heating element might still be good.

In this case, you may need to reach out to a professional to figure out what you should do next. That way, he or she can advise you on how to fix the heating element or how to get a new one.

Install the New Heating Element

If you have a new heating element, this is the time to install it. At the same time, this could be something you need to rely on a professional to help you with. It can be complicated to get your hands on a new heating element for your Bosch dishwasher. It can be even more difficult to install it. For this reason, you may want to reline a professional who can help you install your heating element properly.
