I have an Ariston Euro Combi Boiler SX20.
I have had an on going problem with my hot water only working when the heating is on. I have changed the diaphragm on the diverter valve and checked the triple micro switch on top of the diverter valve.
I have now noticed that opposite the diverter valve on the left of the boiler is another component with a pin that switches a single micro switch. When the hot water tap is switched on this pin fails to rise all the way to the switch, probably only by a few mm, but when the heating is switched on this pin rises fully.
Could anyone please tell me what this component is and how do I fix it.
Many Thanks
Garry
