Hi all
I have a promax combi 28 he plus, around 10yr old. Been serviced.
E119 error came on. Usually the pressure has dropped.
Pressure is fine. Tried it at 0.5, 1, 2, 2.5. No joy
Tried draining to zero and refilling.
Tried reset the system via dial.
Had new pressure switch, no good. Tried refil / reset a few times.
Expansion vessel is fine.
Officially out of ideas! Any help would be appreciated. Had a magnaclean fitted about 3 month ago by British Gas and new heat exchanger. Other than that, no work on it.
Looked all over internet for ideas, and all bases seemed to be covered, but obviously they are not!
My thought is that the pressure switch must go onto something when screwed in, and wondering if that particular sensor is covered in yukky stuff, ad the switch I took out was!
As above, any help appreciated
Thankyou
David
