Error EC Heater Bosch

What is the failure of Bosch EC error affecting your heater?

Water heaters are devices that allow us to enjoy a hot shower, wash dishes or clothes comfortably, and have a more comfortable and cozy home. However, like any electrical appliance, it may experience some faults that can affect its operation, and in some cases, these are beyond our control.

One of these faults is the EC error code that can affect your Bosch or Junkers brand water heater. The EC error code means that the heater is not receiving enough gas to ignite or stay lit, indicating a problem with the gas supply. This can be due to various causes, which we will explore below, and may require anything from a simple DIY solution to the intervention of a specialized technician.

Today, in this article, we will explain what the EC error code is, what its possible causes are, and how we can practically resolve it. This way, you can enjoy your Bosch or Junkers heater without issues and avoid major equipment damage.

The EC error code can have different causes that trigger its appearance, but all of them are related to the gas supply reaching the heater. Some possible causes include:

• A problem with the gas supply reaching your heater: There may be a leak, obstruction, or low pressure in the pipeline preventing gas from reaching the heater with sufficient force. Remember that gas is like water for the human body; without gas, your heater simply won't function.
• The type of gas supplied to your heater is incorrect: It's possible that the heater is designed to operate with a different type of gas than what is being supplied, affecting its performance and triggering the EC error code.
• A defective ignition system: There may be an issue with the igniter or ionization electrodes preventing the necessary spark for igniting the gas.
• A blockage in the exhaust gases outlet of your heater: There might be an obstruction in the duct where the burned gases exit the heater, preventing air renewal and maintaining combustion in your appliance.

It's crucial to address this issue as soon as possible! Since it's a problem with the gas supply, there may be a leak, and this can be very dangerous. A gas leak can lead, in extreme cases, to intoxication or even a fire in your home, so you must exercise extreme caution in this matter.

How to fix Bosch heater EC error?

Fortunately, this issue, being related to the gas supply, can have a quite practical and straightforward solution. Here are the possible solutions you can apply to resolve the EC error code on your Bosch heater:

1. Restart the heater to reset the sensors: Turn off your heater completely and disconnect it from the power outlet for a few minutes. Then reconnect it and turn it on to check if the error has disappeared. This may help recalibrate the sensors and eliminate the EC error code, but if the problem persists, please continue reading the steps we will provide below.
2. Adjust the gas pressure of your heater: Check if the gas pressure is suitable for your heater. You can consult the user manual or the equipment label to find out the pressure recommended by the manufacturer. If necessary, adjust the gas shut-off valve until you achieve the correct pressure.
3. Change the type of gas supplied to your heater: Verify if the type of gas you are using is correct for your heater. You can consult the user manual or the equipment label to find out the compatible gas type recommended by the manufacturer. If it's not, you'll need to replace it with a suitable one.
4. Clean or replace the ignition system: Check if the igniter or ionization electrodes are dirty, damaged, or misaligned. If so, clean them with a dry cloth or electronic cleaner and/or replace them with new ones if necessary.
5. Unblock the exhaust gases outlet of your heater: Check for any obstruction in the duct where the burned gases exit the heater. If there is, you need to clean the entire duct and carefully remove anything that might be blocking this gas outlet. Ensure that the duct is completely free and clean.

Repeat all the above steps if the problem persists: If after trying all the above solutions, the EC error code continues to appear, you should repeat them one by one until you identify the cause and resolve it. If you've already performed the checks for the second time, it's best to leave the problem in the hands of an expert.
