HALSTEAD QUATTRO GOLD BOILER?

My halstead boiler packed in last night..no burner light is coming on, but when pressing the reset button it comes on for a short space of time and then goes off leaving me with no hot water or heating.
The boiler also makes clicking sounds when either the heating or water is switched on.

Can anyone help as an engineer came and said it was probably the pcb board...probably is not good enough from a so called engineer.
