Ariston Microsystem CH works fine but HW sometimes resets

rumpleforeskin · 13 Sep 2013

Hi all

Moved house recently and the boiler in my new place is giving my trouble when HW is selected.

Been running the CH fine this week with no problems but if the HW is selected the boiler will occasionally lockout. Im never there when it locks out so im not sure if the fault occurs during ignition or after its been running.

The HW is a megaflow type with a steel pressurised hot water cylinder, the boiler seems to be similar to the combi at my previous house with the pump etc integrated and a pressurised radiator loop. The difference being that the HW is not on-demand but from the pressurised cylinder.

Any ideas of things I could check or is it time to call out someone?

Thanks
Rumple
