Mend Glow Worm F9

why does my glow worm 24xci flash f9?

the pressure is at 1.8 and then the reading changes to a flashing F9 ... why would that be?

flashing f9 is a rapid increase in temp picked up by flow + return thermister. can be caused by a faulty pump, pump wrong way round or thermisters incorrectly wire - I'd go with the pump option first
