Hello all

as above approx 10 yrs old electronic version, showing A1, pump run dry, which is running & also pumping round rads & hot water, sometimes last's for hours sometimes minutes,
if I can get it through symphony fill.
Get hot water & heating, I am thinking a sensor any ideas would be welcome?

whats your system pressure like ? about 1.2 bar when cold and do you get any cold spots on your rads? and when was it last serviced
 
Hi there
bled system, had service just over year ago when I had to replace ignition probes, also cup & flaps for air mixture must admit had not touched since installed. Good pressure

do you know if the pump has been changed in the last 10 years? and when the pump is working any noise/ bad vibration on the pump?
 
i would say the pump was on its way out but with out seeing and testing the boiler i cant give you a defo answer sorry
 
Hi corbs

is is there anything I could check? I am a qualified electrician & this is my own boiler not a customers , that why i am asking if there is a sensor to check & if so what resistance would this be in ohms.
 
that helps a lot i can give you this number then, they will be able to tell you the resistance levels/ohms

any problems just report back but i suspect as there are now flow sensors on the heating side other than temp sensors the pump is on the way out
