Had an issue the other day where the boiler had locked out. reset it and turned HW on manually. After a while I noticed that the boiler/pump was doing the following :
pump runs for a couple of seconds
boiler clicks a couple of times
pump stops.
Repeat every 10 seconds or so.
Checking the pipes to the cylinder, the feed and return seem to be hot and the cylinder is hot; I *think* it's only doing it when the hot water has heated up.
Just wondered if anyone has come across this before and could give some pointers ?
