Hi
i have an ariston microgenus 27 mffi and i had this unit for 5 years no problems.
Last few weeks the dh water has not been as hot as normal.
I was advised by a friend to flush the dh water exchange unit out.
I drain the system and flush it out , filled the system back up and bleed the pump.
Now as soon as i switch on a red error light come up and the boiler does not light up.
Has anybody got any clues
