How to Fix Bosch Dishwasher Error Code e09

You have every reason to worry when your Bosch dishwasher displays an e09 error code and beeps.

This guide explains the causes of e09 error code on Bosch dishwashers and solutions to fix it.

Causes of e09 Error Code

Although error code e09 occurs rarely, but when it does, it requires urgent attention as it indicates a problem with the Bosch dishwasher heating element.

However, this is not always the case. Your Bosch dishwasher control card may also have some problems that could have resulted in triggering this error code.

If you are wondering what could have resulted in burning the heating element, then please note that it can be due to 2 reasons:

  1. If the water used by the dishwasher is very hard and has very high TDS, then it creates a deposit on the surface of the heating element. This, as a result, creates resistance that converts to heat and ultimately results in the rapture of the heating element.
  2. A second most common reason is the non-cleaning of the drain filter. When the drain filter is not cleaned regularly, the water circulation speed is affected which is directly responsible for overheating the heating element, which can lead to its potential breakdown.

However, if your dishwasher warranty period has already passed, and you are comfortable with troubleshooting it yourself, then try the below methods:

Power Cycle your Dishwasher

Maybe the error is due to a communication problem inside the dishwasher, and in that case, it can be easily fixed by power cycling your dishwasher:

  1. Turn Off your Bosch dishwasher.
  2. Take its plug out of the socket for 5 minutes.
  3. Connect and turn it ON again.

Check Dishwasher Thermostat

The faulty thermostat on your Bosch dishwasher will turn off the dishwasher at the wrong temperature and might give error code e09.

To check the thermostat, first, unplug your dishwasher from the power outlet.
