When I turn on the hot water tap the ignition doesn't always light up. I've been told the pressure is too low as it is below 1 but I don't know how to get the pressure up.
these will run as low as 0.5 bar pressure. whne u turn hot tap on green light should start 2 flash if not then aquasensor has failed. if it does then diverter valve is jammed in htg position. email DPMARTIN17@AOL.COM
