HELP , boiler trips house electricity when turned on

[sam423]

SIME OIL BOILER 1992
DE DIETRICH BURNER 2002

When my boiler is turned on it trips out the whole house electricity supply.
i can turn down thermostat on the boiler and turn on the boiler so the light is lit up but when i turn up the stat it trips out.
i have changed the fuel control box on the burner but still same problem.
funny thing is that when i unplug everything on the burner except the fuel control box it still happens, so it cant be the solenoid/transformer/coil etc as they are all unplugged
that only leaves the boiler itself but theres only 3 simple controls on it like on/off switch,reset button and thermostat.

when i turn it on via the programmer, the zone valve moves then pump comes on then boiler light comes on but turn that stat up and lights out

Any ideas anyone??

Also if i cant fix it , is it a straight swap for another burner of a different model if the power outputs are similar or will i need to make any adjustments like airflow etc?

just asimple question of tracing the short to the item causing it by elimination.

Dont know.awat at the mo but its been workingfine for six months.could size of breaker be causing problem now?

 

[lame plumber]

unlikely a breaker problem more likely a short just need to track it down

 

[sam423]

Will the fan and the motor be hardwired to the control box as u cant seem to unplug thosr?

Don't do oil but a mate of mine had same problem on his gas system the other day...
Turned out he had a leak and the actuator on his zone valve for the heating was full of water. Tripped the electrical whenever he turned the stat up to create demand
