My vokera maxim 24 won't come on water. The plunger works

Customer Question

My vokera maxim 24 won't come on for hot water. The plunger works and operates the microswitch but won't bring the boiler on .I've had the microswitch replaced but still no good .It works on heating but only if I give it a quick turn on of the fill valve even though there is 2 bar of pressure in the boiler . Thanks for any help
