Mend Ariston Help Combi Dropping Pressure

ariston eurocombi "cutting out"?

hi,can anybody help ! ariston combi probably about 5-6yrs old,it kept dropping pressure so i kept topping it back up to 1bar,no probs for ages then it started again you could hear what i think was the pump when it hit low pressure,but now it ignites for about 5secs an then cuts out an throws the little red pressure light on.if started from cold it works up to a certain temp i think so could it be the thermostat or something ?? any help much appreciated before i have to ring a plumber.

if its still leaking outside you need a new prv (pressure relief valve).
