Error E09 Dishwasher Bosch

What is the fault of the E09 Bosch error that is affecting your dishwasher?

Over the years, the Bosch brand has become synonymous with excellence and quality. But if you have a dishwasher from this brand, you may at some point encounter the Error Code E09 on the display. Please note that this error code is equivalent to Bosch error codes 9 and 09 for dishwashers. Therefore, if we mention that the error code is E09, understand that it is the same for error codes 0 and 09, so the causes and solutions for these codes are the same for each of them.

This code indicates that there is a problem with water heating, which can affect the operation and the result of your dishwashing. In this article, we explain what this error means, what its possible causes are, and how you could resolve it in the best way.

The E09 error code, as we mentioned earlier, means that the dishwasher is not heating the water correctly. This can be due to a thermostat failure, a heating element issue, or a malfunction in the electrical circuit connecting them. If the water doesn't reach the proper temperature, the dishwasher won't be able to dissolve the detergent effectively or remove dirt from the dishes. Additionally, the washing cycle may be extended or interrupted, leading to increased water and energy consumption. The Error Code E09 can have several causes, including the following:

• The thermostat is broken or out of calibration and does not measure the water temperature correctly.
• The heating element is damaged or dirty and does not heat the water sufficiently.
• The electrical circuit that connects the thermostat and the heating element is broken or loose and does not transmit adequate current.
• The temperature sensor is defective and sends an incorrect signal to the control panel.
• The control panel is damaged and does not regulate the water heating correctly.

How to fix the E09 error on the Bosch dishwasher?

Are you ready to know the repair of error E09 in your Bosch dishwasher? To solve this failure in your precious appliance, you can follow these steps that we indicate below:

1. Restart the dishwasher to reset the sensors: To do this, disconnect the dishwasher from the electrical outlet for a few minutes and then plug it back in. Now, turn on your dishwasher and check if the error disappears or reoccurs.
2. Check the thermostat and heating element of your dishwasher: You will need to remove the lower panel of the dishwasher and locate these components. Check if they are dirty, rusty, damaged, or sulfated, and clean them or replace them if necessary.
3. Inspect the electrical circuit of your dishwasher: To do this, you will need to use a multimeter to measure the continuity and resistance of the wires connecting the thermostat and the heating element. If you detect any broken or loose wires, damaged, burnt, or scorched, then replace or repair them.
4. Examine the temperature sensor of the dishwasher: Locate this component inside your dishwasher. It is typically near the heating element. Use a multimeter to check if it is in good condition or if it needs replacement.
5. Inspect the control panel of your dishwasher: To do this, you will have to dismantle the front panel of the dishwasher and check if there are any burnt or damaged components. Use a multimeter to detect faults that may not be visible to the naked eye. Also, check for swollen, burnt, or sulfated components. If you find any, you may need to replace the control panel with a new one. However, it's a good idea to perform maintenance with electronic cleaner and, as a last resort, ultrasonic cleaning.
6. Repeat all the previous steps if the problem persists: Perform a second check of everything we've mentioned earlier. If, after all the necessary checks and repairs, the E09 error code continues to appear, there may be a more complex issue that requires professional intervention.
7. Contact Bosch technical support to resolve the problem: If you cannot resolve the error on your own or prefer to leave it to the experts, you can get in touch with Bosch's official technical service and request a home visit. They will diagnose and repair your dishwasher with all available warranties and necessary measures.

To conclude our tips guide, the E09 error code indicates there is an issue with the water heating in your Bosch dishwasher. This can be due to a malfunction in the thermostat, heating element, electrical circuit, temperature sensor, or control panel.

To resolve the E09 error code on your Bosch dishwasher, you can restart the dishwasher, inspect the involved components such as the thermostat, heating element, electrical circuit, temperature sensor, and control panel, and replace them if necessary. Alternatively, you can contact Bosch technical support if you are unable to resolve it on your own.
