Got fd code on Ideal Logic Heat 15. Had two plumbers out and no joy. It’s had a new water flow sensor, flush with sentinel x800 and refurbished grundfos water pump.
Boiler tries to light and water pump power light comes on but goes off immediately and boiler flashes fd again.
It’s heat only so I have no gauges, tank in airing cupboard. Thank you.
