HI guys my linear 24 has a problem with the hot water.
Basically the boiler fires up fine heats water but then after about 1min or so starts making a pretty awful noise and sometimes locks out with code 03 flashing.
If i turn the temp down it doesnt do it and it does sound almost like the water is getting too hot.
I have changed the thermistors and the secondary heat exchanger was replaced just over a year ago. I was thinking could it be the coil that the water is heated in?
Could this be scaled up? If this is the case can they be cleaned out and is this a easy job.
Thanks as always guys.
