E
The operations stated below are indispensable for checking the quality of the relay electric contacts positioned on the board.
Replace the fuses checking that there are no short circuited components (pump, fan, gas valve, etc...).
Check safety device times and the complete power removal from the gas valve, operating as follows:
- close the gas supply and make a functioning request;
- check that, after 2 ignition attempts, the display shows error "01";
- with the help of the single wire wiring diagram, use a tester to check that there is no voltage (230 V DC) on the gas valve power supply cables.
