Any of these situations can cause the electronic PCB board of your heater to malfunction, resulting in the device not turning on or shutting off suddenly, displaying the error on the screen.

How to fix Bosch heater error E0?

Hello there! Have you been experiencing issues with your Bosch water heater? Has the Error Code E0 appeared on the screen? If so, don't worry, in this article, we will explain what this error means, its possible causes, and how you can resolve it.

The good news is that there are some solutions you can apply to fix this issue. Still, keep in mind that if the situation becomes challenging, you may need to call Bosch technical support. To resolve Bosch Error Code E0 on your heater, you can follow these steps:

1. Restart the heater to refresh the sensors: Sometimes, the electronic board may become misconfigured or erratic due to a power supply failure, so we will try to restart it. To do this, simply turn off your heater completely and disconnect it from the power outlet. Once some time has passed (at least 15 minutes), reconnect your heater to the power supply and turn it on to check if the error has disappeared. This may help reset the normal operation of the board and sensors.
2. Check all electrical and electronic connections of the heater: Ensure there are no loose, broken, torn, burned, or scorched wires, and that the connections are well-adjusted and clean. If you find any issues, repair or replace damaged cables and make sure everything is properly connected.
3. Inspect for moisture or water leaks in the heater: Thoroughly inspect the interior and exterior of the appliance and look for signs of moisture, rust, or corrosion. If you detect any leaks, close the water shut-off valve and repair the pipe or joint that may be defective. Also, check the hoses and ensure there are no water leaks. If there is moisture on the electronic board, you can use a hairdryer to dry it and then apply some anti-corrosive product to protect it, as well as a bit of electronic cleaner.
4. Repeat all the previous steps and make sure to follow everything to the letter if the problem persists: You may need to perform a second check of everything we have mentioned earlier. This time, make sure to follow all the steps to the letter.
5. Replace the electronic PCB board if you think it may be damaged: If, after following the previous steps, the E0 error code persists on your heater, then the electronic board may be irreparably damaged, and you may need to replace it with a new one. You can contact Bosch's official technical support and request a quote for the repair or replacement of the part according to your heater's model. If you have knowledge in electronics, you can use a multimeter to check the functioning of this board and confirm once and for all if it is irreparably damaged. You could try to revive it with good maintenance, some electronic cleaner, and an ultrasound cleaning, but we can't promise anything.

Request a review of your heater with Bosch technical support: If you have given up and have been unable to solve this problem, it's best to contact Bosch technical support and request a home visit. We are confident that they will provide an appropriate solution to this problem, and the best part is that you will have all possible guarantees.
