my potterton performa 28 keeps cutting out whilst the hot water tap is on,
the led indicator builds up to 80 then cuts out,there is no fault light being lit on the fault panel,ive recently changed the hot water temp sensor and the problem is still there......

after it cuts out it restarts after about 5 sec,ive tryed running the CH and it doesnt cut out...

ive had a plumber out and he checked gas valve which he said was ok and he indicated that it could be a fault on the pcb which he quoted me £150 to change...

The problem has gradually got worse over the last 12 months to the point that we can no longer run a hot bath..

my water pressure is really good so i dont think its anything to do with that

does anyone have any ideas? thanks for any advice given
