Dear all,
There is no Domestic Hot Water (DHW) coming out of my Alpha 240E boiler. Only the Central Heating (CH) working i.e the radiators getting hot every time there is a demand for DHW, the following tests have been carried out:-
• Switching the Selector switch to DHW only (the tap picture), turn on the sink tap, the boiler fires up normally, the DHW does not get hot at all where as the radiations get very hot.
• Switching the Selector switch to DHW and CH (the tap and the radiator picture), turning off the CH on the timer, turn on the sink tap, the boiler fires up normally, the DHW does not get hot at all where as the radiations get very hot.
• The only time we get warm DHW when the central heating has been working for a while.
In both cases both pins of the primary and the DHW of the diverter valve are seen to be moving and pressing the microswitches.
Can some one help please
