Error F37 Boiler Cointra

What is the F37 Cointra error affecting your boiler?

Hello there! If you're here, it's because you have a Cointra boiler and, surprise, surprise! You've encountered the F37 error code. Well, you don't have to worry because we've found that this problem is very easy to fix. Today, we'll explain what this error means, what its possible causes are, and how you can quickly and easily fix it.

Cointra boilers are very efficient and safe heating systems, but like any electrical appliance, they can experience some faults that affect their operation. One of them is the F37 error code, which indicates a problem with the water supply entering the heating circuit.

The F37 error code appears on the boiler's digital display when the water flow entering the heating circuit is very low or insufficient. This can cause the boiler to not function properly or to shut off suddenly. Some of the possible causes of this error, no more, no less, are as follows:

• The water shut-off valve is closed or partially open: This prevents water from flowing normally to the boiler and reduces the circuit pressure.
• There is a water leak or a breakage somewhere in the heating circuit: This causes water loss and reduces the flow and pressure of the circuit.
• There is accumulated air in the heating circuit pipes: This can occur due to poor purging or incorrect installation. Air takes up space in the pipes and hinders water flow through the circuit.
• There is dirt or sediment in the water filter or pipes. This can obstruct water flow and reduce the flow and pressure of the circuit.

These are all the causes that can lead to the F37 error code appearing on your Cointra boiler. But let's now look at the solutions so you can fix this problem today.

How to fix the F37 error on the Cointra boiler?

If you've encountered the F37 error code on your Cointra boiler, you don't need to worry. There are some solutions you can apply yourself to resolve the issue and get your boiler back to working correctly. We'll provide you with a list of solutions, so take note of each one and don't skip any:

1. Turn off and disconnect your boiler from the power supply to restart and refresh its sensors: This can help the boiler recognize the actual water flow and adjust to it. To do this, completely turn off your boiler and disconnect it from the power outlet for a few minutes.
2. Fully open the water shut-off valve or adjust it to have appropriate pressure: This will allow water to flow normally to the boiler and increase the flow and pressure of the circuit. Consult the user manual provided by Cointra to verify the correct water pressure according to your boiler model.
3. Check for any leaks or breaks in the heating circuit and repair them if necessary: This will prevent water loss and maintain the flow and pressure of the circuit. Inspect the entire piping circuit of your boiler, also check the joints and connections. Ensure there are no leaks in the entire system and verify if the F37 error code has disappeared.
4. Bleed the radiators and pipes to remove accumulated air in the heating circuit: This will facilitate water flow through the circuit and improve its performance. The boiler has its own procedure for this, consult the manufacturer's manual and perform the automatic bleeding procedure provided by the boiler.
5. Clean the water filter and pipes to remove dirt or sediment that may be obstructing water flow: This will undoubtedly improve the flow and pressure of the circuit and prevent future faults. Sometimes, depending on the region where you live, the water can contain many minerals, lime, and sediments that can clog your boiler's water filter. Clean the filter or replace it with a new one and check if the F37 error code has disappeared.
6. If the problem persists, please repeat all the previous steps and make sure to follow everything to the letter: It may be necessary to repeat the solutions mentioned above to completely eliminate the F37 error code. There may be some detail you missed or you may need to perform the process several times to achieve a satisfactory result. Follow all instructions to the letter but this time with more attention to detail. If the problem still persists, please leave it in the hands of an expert with knowledge in the field.
7. Call a Cointra technical service and request a home visit for a more thorough inspection: If you've already tried all the previous solutions and the F37 error code continues to appear on your Cointra boiler, the problem may be more difficult to solve and you'll need the assistance of a qualified professional. In that case, please contact Cointra technical service and request a home visit to have your boiler inspected and repaired if necessary.

In summary, the F37 error code on Cointra boilers indicates a problem with the water supply entering the heating circuit, which may be due to very low or insufficient water flow. The possible causes include: a closed or partially open shut-off valve, a leak or breakage in the circuit, accumulated air in the circuit, dirt or sediment in the filter or pipes. And among the possible solutions to fix this problem are the following:

• Turn off and disconnect your boiler from the power supply to restart and refresh its sensors
• Fully open the water shut-off valve or adjust it to have appropriate pressure
• Check for any leaks or breaks in the heating circuit and repair them if necessary
• Bleed the radiators and pipes to remove accumulated air in the heating circuit
• Clean the water filter and pipes to remove dirt or sediment that may be obstructing water flow
• If the problem persists, please repeat all the previous steps and make sure to follow everything to the letter
• Call a Cointra technical service and request a home visit for a more thorough inspection

We hope this article has been helpful and that you've been able to fix the F37 error code on your Cointra boiler. This is a problem that can be very easy to fix, so don't be discouraged if you encounter this error code. Good luck with the repairs and until next time!
