Ariston eurocombi diaphragm replacement.

[baronsouthside]

Following tips and hints from this and other web sites, iv hopefully diagnosed my boiler problem as a faulty diaphragm in my diverter v/v. (No DHW when asked for. Spindle not making micro switch to start boiler.)

I have 3 queries.

firstly, when iv fitted the new diaphragm what do i need to do then? Im guessing there will be air in the system so is it just as easy as bleeding the rads or do i have to look for a better bled point somewhere in the boiler itself.?

Secondly, Im i best to desludge the system with an additive before or after the diaphragm replacement

And finally on a slightly different theme, My central heating is controled by a danfoss 103 mechanical controller, however it is not very flexible as i work shifts and i would like to fit an 7 day or a 5/2 day electronic timer instead. Could someone please advise on a suitable like for like, no changes to the wiring replacement before i shell out the money.

Im a time served mechanical maintainance engineer so i kinda know what im doing.

Thanks

I am not so sure!

The DHW diaphragm is only in the mains water so the system water is not disturbed and cleaning it is not therefore associated with changing the diaphragm.

Any electronic time clock will be able to interface with the two wire control circuit of your boiler.
