my gv wont stay lit after ignition due to pressure sw opening..
pressure switch is set at 1.4 in water.
i measured the pressure at 1.5 in water upon start up using a manometer
as soon as ignition occurs the pressure suddenly drops to approx 0.8 in
during firing , the pressure reads 1.0 in water which is below the set point of the pressure sw
i have replaced circulator motor with no improvement
I also flushed out the heat exchanger with water per wm procedure no improvement
I suspect my 25 yr old boiler is full of sludge or contaminats
Does anyone have any ideas on how to clean the heat exchanger beyond a water flush
