Got called to a job as the WB conventional 30cdi was overheating and cutting out. Customer stated its been doing it on off at increasing frequency for about 2 months, a reset would sort it out. Now it won't run for more than 2minutes.
checked pump, pipes either side cold, pump burning hot, took off pump head and was rammed with debris and rusty lumps. I replaced entire pump.
problem the boiler now runs and will heat the hot water cylinder and two towel rads on primary circuit. Then cut out again after about 10minutes. If I turn heating on as well as hot water nothing heats up it just pipes until about 3m from hex.
Customer did say that they had personally dropped of 4 radiators for decoration purposes, I'm thinking maybe they dropped wallpaper or filler or something into empty rad then refitted it and pushed it into system.
Im thinking a power flush as it seems like a circulation fault? I don't have power flush equipment so use a friend as a subby who sorts it for me, do you think this is the way to go?
thanks Nick
