sime boiler

[brummieblue]

My sime friendly format 80 e has 2 problems. It fails to ignite when it comes back on automatically, this I believe requires a new pcb, and when heating is on the 'overflow' constantly drips.The pressure gauge shows normal but is high when heating is on. Can anyone help please.

do a search on expansion vessel

By the overflow i assume you mean the pressure relief valve (prv) on the boiler?

how high does the pressure go?

also your post is incomplete if the prv is letting water out you will lose pressure at some point and have to keep refilling the system is this the case?

yes I do have to top up occasionally, if the boiler is off, the pressure remains normal, however it rises above the top limit when heating is on. Thanks for responding.

you at the least need to recharge the vessel

 

[brummieblue]

how do you do that?

 

[kevplumb]

drain the boiler
look at the top of the boiler and if you see a car type valve get a tyre guage and check the pressure
should be between 1 and 1.5 bar
if not nick the kids bike pump and go for it
if you press the valve and get water out the membrain has gone
(its sat eve so has mine)

Sounds like a new igniter pcb. Don't forget that the SIME has two pcb's
