ITS ONE OF 2 THINGS THE DHW HEAT EXCANGER OR ITS YOUR PRESSURE VESSEL,CHECK 4 WATER AT THE VESSEL AT THE BACK,IF NON U COULD RECHARGE IT WITH A BIKE/CAR TIRE PUMP......BUT U MUST ALSO HAVE THE BLOW OFF OPEN AT THE SAME TIME AS PUMPING......IF THE GUAGE IS CONTINUALY RISING WHEN THE HEATING SYSTEM IS FULL ITS YOUR HEAT EXCHANGER.GOOD LUCK!
