if its a potterton suprima, you may have to go for a new circuit board if it constantly needs resetting, but check stats and thermistors, what a great guy mr fixit must be, id be out on my speed boat on the med if i was on 80k pa, maybe he is just touching base with us loosers to remind himself how great he is. salute
