Having read through the forum on all the Linea 24 DHW issues I thought I had all the info I needed to repair mine. I replaced the Secondary Heat Exchanger, fitted an overhaul kit to the Diverter Valve along with a new DHW thermistor to find I still have the same problem
When the Hot Tap is turned on, the boiler fires up but doesn't get the water hot enough. if I restrict the water flow using the restrictor valve on the boiler, the temperature readout on the boiler will rise to 55 at which point the burner switches off until the water temp falls to 40/45 then it will fire up again in a repetitive cycle. I've checked the Diverter Valve Motor and that is functioning correctly. Anyone any ideas what I need to check next ???
