Hello. I am new to this forum. I have a Keston C36. It overheats every time we use hot water. The error code E03. I have read the manual and tried everything without any joy. To the point where over the last 2 years we have pressed the reset button that many times it has worn out. The water pressure is at 1.1 bar and to be honest the mains pressure doesnt seem to be any higher so cant get it up any. (We live in the south of France ) It does'nt overheat when the central heating is on usually.If we shower when the central heating is actually running , it tends not to overheat as much . If we shower when the central heating is not on it fails every time. We are so fed up of it we are looking to change it if we cant find a solution. Any help would be really appreciated.
It runs on mains GAS. Thanx Derek
