My Worchester 24i RSF stopped giving heat to radiators & intermittant water?

if you disconnect a room stat you usually have to put a link in between the terminals you take the stat from on the boiler or heating will not work, as for hot water if i remember right this boiler has a flow switch on the hot water side if it doesnt check the diverter valve operation and the thermisters

hi, if you are using a mid port valve on the system then this could be the problem, most valves have a manual lever try moving it to either position and see if the results change, if so suggest changing it. most valves have a relpacement head so no need to drain down to replace just a matter of unclipping and swapping a few wires
