Error E02 Dishwasher Bosch

What is the breakdown of the E02 Bosch error affecting your dishwasher?

Have you noticed that your Bosch dishwasher is not heating the water as it should? Have you seen the E02 error code on the display? If so, you don't need to worry. In this article, we will explain what this error means, its possible causes, and how you can resolve it in the best possible way.

The E02 error code indicates that there is a problem with water heating in the dishwasher. This can affect the appliance's performance and the quality of your dishwashing results. Additionally, it can lead to longer-than-normal wash cycles or interruptions.

Among the possible causes of the E02 error code in Bosch dishwashers are the following:

• The heating element is damaged or dirty: The heating element is responsible for heating the water inside the dishwasher. If it is damaged or has sulfate or dirt buildup, it can prevent the water from reaching the correct temperature.
• The temperature sensors are damaged or poorly connected: Temperature sensors detect the water temperature and adjust it according to the selected program. If they are not functioning correctly or have issues with the wiring, they can send incorrect signals to the electronic control panel and trigger the E02 error code.
• The thermostat is broken or misaligned: The thermostat controls the water temperature and keeps it constant during the wash cycle. If it breaks or becomes misaligned, it can cause the water to heat excessively or, conversely, not heat enough.
• The heating element relay is burned out or loose: The heating element relay is the component that turns the heating element on and off based on the control panel's commands. If it burns out or becomes loose, it can prevent the heating element from receiving electrical power, resulting in inadequate water heating.

How to solve the E02 error of the Bosch dishwasher?

Luckily, there are ways to fix the E02 error code on your Bosch dishwasher and best of all, you could try to fix this problem yourself without needing to go to technical support. unless it is really necessary:

1. Restart the dishwasher to reset the sensors: Sometimes, a simple restart can resolve the issue. To do this, unplug the dishwasher from the power outlet for a few minutes, then plug it back in. Turn on your Bosch dishwasher and check if the E02 error code has disappeared.
2. Inspect the heating element and perform maintenance by cleaning it if necessary: To access the heating element, you'll need to remove the bottom panel of the dishwasher and locate it at the rear. Check for any signs of damage or dirt and clean it with electronic cleaner and/or a damp cloth if needed. You can also measure its continuity with a multimeter to verify proper functioning.
3. Check the temperature sensors and their wired connections: Temperature sensors are located at the bottom of the dishwasher, near the heating element. Ensure they are properly connected and check for any signs of deterioration. You can also measure their resistance with a multimeter to confirm they are functioning correctly.
4. Inspect the thermostat of your dishwasher and adjust it if necessary: The thermostat is located at the top of the dishwasher, near the detergent dispenser. Verify it is securely fastened and check for any signs of breakage. You can measure its resistance with a multimeter to confirm proper functioning. If it's misaligned, you can adjust it by turning its screw with a screwdriver.
5. Check the heating element relay and replace it if necessary: Check if this relay is well soldered and if there are any signs of burning. You can also measure its continuity with a multimeter to confirm proper functioning. If it's damaged, you'll need to replace it with a new one.
6. Repeat all the previous steps if the problem persists: We recommend performing a second check of all the steps described above if the issue persists. If, after completing all the checks and cleanings, the E02 error code continues to appear, there may be another damaged component or a more complex issue at play.
