    Hello nation, hope you have good evening.
    Have boiler`s fault F-1, but presure on the gauge over 1 bar.
    Tried to drain water from boiler to check for any dirties. When I was draining water I detective black fragments, so I rinsed the boiler`s system. When I refilled boiler and tried to launch it, but without reasult. So I tried to clean presure sensor type 505 as it response for presure in system. But again without result.
    May be someone have some ideas about it? Maybe possible some how launch the boiler without sensor just to find out if problem is presure sensor?
    Thank you all for advice.
