Evening , I appreciate that there are a number of similar issues on this forum and others , however none of these have helped so I'm asking for my specific issue.
My boiler is 20 years old , only previous issues have been with PCB which Ive replaced a number of years back
My CH is fine , however my hot water even with temp gauge on midway gets pretty hot , water pressure is good , however after approx 60 seconds it becomes "warm" and there is a noticible increase in water pressure ( not the same as some other posts , it doesnt go cold ) , it then gets hot again and repeats the cycle . I have replaced the temp sensor on the inlet pipe ( CH ) no difference .
Any ideas please , I have read that it may be the heat exchanger , however I cannot find any instructions on how to clean this on this model .
It does feel as if it is some sort of temperature safety feature kicking in .
Thanks in advance .
