Hello
Possible you have a bad hot water control or low water cut off is going bad.Sounds like a control problem,thing is there are 3 or 4 different possibilties.

If this is stopping the gas flow then you need to have the boiler looked at by a service person.

Hi, I've a fagor feb20e Eco plus combi boiler in


There is a flow sensor in the circuit and it is not sensing the lower flow from just the hot water. When you put it on heat though it does.

Ariston euro-combi boiler not giving hot water


odd noise like popping or singeing fire....clicking noises.....sounds like you have a water leak putting out the pilot.......or your thermo coupling is bad....or the noise is the tank full of calcium buildup and that will make noises when the burner is on

Pressure gauge reading zero


Hello Mark
First of all turn on a hot water tap and keep it running whilst you check to see if your boiler is firing up, if it is not then try to restart it, you should hear the flame if its running, turn your tap off then just stand by the boiler for a few minutes to see if the pressure gauge starts to rise, if it doesn't rise you will never get any hot water, you will have to add some pressure to about 1 and a half on the dial, to do that is simply turn on the water valve in the bottom of your boiler and watch your pressure gauge rise to about 1 and a half then firmly turn it off again, it looks like a small tap like the one at the back of your washing machine pipe, it's ok you will hear the water rushing in, now with your gauge at about 1 and a half and your boiler running your water will get hot

Switch heating on, hear a click that we normally hear then boiler fires up. Then goes off after about 30 seconds. Then won't come back on, though we still hear the click. Wait a while before trying...


could be a number of things, it could be cycling on the high limit switch, (lack of water flow, or pump) this would be my guess if you are not resetting power and the unit is trying to restart. It also could be the flame sensor not proving ignition. hope this helps!

Water heater pilot light


it also sounds as though the pilot injector could be blocked so when the boiler comes on it extinguishes the pilot & then when the burner goes off boiler shuts down, or also the pilot rate maynot be set right, so when the main burner kicks in it robs the pilot of the gas it requires.
It could be that, or there is lack of ventilation for the boiler, so you get flame lift off when the boiler fires?
