boiler not working

[keser]

i have a glow worm micron 66 ff boiler, it comes on for 5mins and then clicks off, the pump and the surrounding pipes are very hot but radiators are cold
The 2 lights ( reset and boiler) remain unlit
I have tried to reset but when i turn switch clockwise you can normally here it click and the boiler light up, this is not happening.
When i checked the pump last night it seemed to be working but i cant check it now because nothing is happening.
Is it a blockage? i opened a few raditors and the water is flying out ok
Do i need a system flush?
would it solve the problem?

need double advice please

Thanks

What pressure is in the system (minimum 1 bar)

Are most (or all) of the radiators open (left to open) and bled (air released until water comes out)so the heat has some where to go, just check if you are not sure.

Are all fuses okay?

You seem to be describing two faults, a lack of circulation and a boiler which you say stops working.

But you dont say what is done to make it work again.

Get a competent engineer to diagnose the fault before you rush into an expensive powerflush.

thanks for your replies
Yes the micron has no bar indictators to show pressure and yes i only opened the radiator nearest the boiler which showed good pressure when opened
Yes i didn't make myself clear, to get it working again i let everything cool down and then i done reset but it didnt come on straight away as it should do, it normally clicks on when you turn the reset switch clockwise and the boiler fires up, this isnt happening now?

Is the pump running?

 

[keser]

the pump seemed to be working last night but i cant tell now because i cant fire her up, can i test the pump without the boiler being on?

up date gents
i took the screw out the front of pump and moved the speed indictator on side of pump slightly, pump started and then i done a reset on the boiler it started straight away! i m just going to see wether it clicks off after it gets hot9 which i expect it to) and then i will come back to you

 

[keser]

yep, as i thought after about 5 mins boiler clicked off, pipes are all hot near the boiler, pump working but radiator nearest to it stone cold and normally warms up very quickly!
Its got to blocked surely?

 

[keser]

anyone around still?

Overheat stat?

Just cos the pump motor is rotating don't mean the impellor is pushing water around!! I still think the Pump is the key to this one!!

 

[MC2012]

do you have hot water? is the 3 port or 2 port motorised valve opening for the central heating?

I think the OP has gone AWOL gents.

Is it possible that an isolation valve has been turned off by mistake just under the boiler? This happened to someone - when topping up the system at the filling loop, a valve on the return pipe was knocked off. This boiler had isolation valves on all the connections flow, return, gas , filling etc. - as part of the boiler (i.e not added by the plumber).
