    Hello. First of all, you need to check the safety pressure switch in your boiler. On the diagram that I attach, it is located at number 13. Also check the operation of the installation pressure switch, No. 17 in the circuit.

    If during the verification of these two relays no malfunctions are detected, then the problem is in the valve itself, which discharges water. It is possible that it broke and therefore does not respond correctly to the increase in pressure in the system, dropping it, considering it erroneously excessive. But most likely, the cause of the problem is in one of the relays, No. 13 or No. 17 in the circuit.
