Worcester Boiler not Firing

[jaymis]

Hi,

I have a 3 year old Worcester Greenstar 24ri condensing boiler.

The fuse blew a couple of times and later found out there was a water leak from magnaclean.

Our magnaclean sits under the boiler cupboard with Honeywell controllers under it.

We have today replaced rubber ring in magnaclean causing leak but now the boiler won't fire up.

Unfortunately the way the magnaclean is position directly under boiler cupboard it's difficult to
remove the air from top of magnaclean.

The temperature stat keeps saying low battery but the its fine.

The boiler was working until magnaclean was cleaned.

The hot water and heating not working. The boiler fires up for 2mins and dies.


I am hoping its something simple but not sure what else to check.

Any ideas ?

Have you opened the isolation valves back up? If not sounds like air in Magneclean or somewhere else in the system.

Yes check the isolation valves.

Yes the isolation valves were opened back up after cleaning Magnaclean.

I can't get to the top of the magnaclean to remove air as it is located under a boiler cupboard.

Is there any other way to remove air ?

What's your boiler pressure showing ?

There is none with this boiler I don't think.

This is a condensation boiler and not a combi.

Bleed the pump. Have you got invented cylinder?

Cylinders were invented years ago 😉

How much water dripped on the controls when you changed the ring?

I can't seem to remove screw at front of pump its very stiff don't want to damage head.


Also I am not sure how much water if any went into Honeywell controllers there was hard water residue

on surface as they were boxed in. But I had them covered with bin liner when cleaning magnaclean.
