iDEAL CONDENSING BOILER NEW ( 2010 ) ( ICOS HE15 )
NEW wILO pump fitted last year ( was noisey for a while ( cavitation - vented system ) )
so - hot water fine
when demand for CH = nothing - fault code H6 ( not in manual... )
thermostat seems fine ( lights up... )
pump leaks water as soon as centre screw is loosened - but is otherwise dead - control box(!? NEAR TO PUMP / CYLINDER - has 3 lights and a button - clicks flashes green red when button pressed (!!? )
so is pump US? ( 5 year gntee... ) or...?
