Y plan system heating not working and no hot water

[Jimbo1983]

Hi

I have a y plan central heating system pump and 3 port valve seem to be working fine. But have no hot water or central heating was working fine when I went to work yesterday and today it's not. So any ideas would be great as don't want pay bank holiday rates if there is a simple fix.

Thanks

So the 3 port motors then the pump runs? What boiler is it?

Pump sounds like it is running normal, when I switch on the hot water the motor seems to make a noise and move like it always has. The boiler is a maxol morroco.

Remove the large screw in the centre of the pump and check it is spinning when the system is turned on.

Have a cloth to hand as a small amount of water will come out. You can spin the pump with a large flat screw driver.

Is the boiler generating any heat?

 

[Dopeydaz]

I'm not familiar with that boiler. I'll try and see if I can find a manual for it. Being an older boiler it probably has a manual overheat stat. That's what I would check first.

Everything is cold well nothing that is hot..

Does this boiler have a permanent pilot light? Is that lit?

 

[Jimbo1983]

Yes it does.

Would the Immersion heater cause any problems?

Immersion wouldnt affect the Central Heating. If you've neither hot water or central heating then first thing would be to check the boiler is firing.
