    Vaillant Eco Tec plus combi, pressure was on zero and had stopped working. Tried turning the grey taps connected by the silver flexible metal hose underneath but nothing, no water, sound or anything. Unscrewed taps and turned valves with a pair of pliers but still nothing? The right tap turned off would stop the hot water flow out of the tap, turning it back on allowed the water to flow again so mains definitely going through that part.
    Thanks

    One of the filling loop valves may have siezed or there could be an airlock. When was the last time the system was topped up?
