AAExcessive temperature difference between the heating flow circuit and the domestic hot water (DHW)The motor of the 3-way valve (8717204345) does not switch or makes poor contact in its white connector, leaving the boiler in a single circuit and causing that differential; check by manually activating the V3V/test and measuring that 24 V reach the motor and that it rotates/switches between DHW and heating.
