Worcester Heatslave Junior hot water no heating

[Darrylrc]

I have a Worcester Heatslave Junior. The problems with it is that I can get hot water, but no heating, if I turn the heating dial to on and turn the room thermostat to full the boiler fires up for about a minute but it then cut out.

does it lockout on overheat?

sure its not a heatslave senior

Its not overheating, other than the rads don't come on at all, the boiler seems to be working fine. What do you mean lockout on overheat.

Holty, its definitely a Heatslave Junior, its wall mounted, and about 20 years old

Honeywell 3 port divertor valve in boiler , good chance the synchron motor in it has gone,. pull lever over to manual position to give you heat

I'm a complete novice at this, where will I find the 3 port divertor valve in boiler, and how do I change it to manual.

Thanks in advance

Its a silver thing with 3 pipes to it .
Lever on side that pulls across and hooks in place ,
That is only temp repair as to get you heat and needs looking at properly.
