Glowworm swift flow combi boiler?

Hot water runs and then boiler goes off(green light out) when you bang the boiler case sometimes the boiler will start to run again(green light back on). Also the radiators get warm when the water is running.

rite lee sound like your ganna have an expensive 1 on your hands m8 .. rads warming wen hot waters on means that your divertor valve is passing which probly means youve got a cruddy sludged up system..id drop a magna clean filter on the sytem if youre gonna change the divertor cuz it will happen again, you can confirm its passing by turning off the heating flow valve under the boiler..but i wouldnt advise doin it if they lookm old or slightly coroded as 9 out of 10 times they leak if you touch them..but %100 if you run the tap and the flow pipe gets hot to the heatin ure divertors gone..these are quite old aswell now ent they mate!! and id say that thers probly either a bad conection at the mains into the boiler..check the live neutrel earth conections into it if ther ok its gonna be a pcb jobby more than likely...both parts well in excess of £100 m8 bad times!! hope this helps
