Runs but throws main breaker, and sparks fly from the electrical plug in breaker on the cord

VERY DANGEROUS YOU NEED TO CHNAGE OUT THE ELECTRICAL PLUG CORD AND CHECK THE TERMINAL BLOCK As u have a short somewhere its easy to change the terminal block

Overheated wire can catch wire and melt other wires.
Sparks from a loose connection usually will not damage other wires, unless the short circuit has been going on for a while... but usually a short circuit will trip breaker or the arcing will completely short out and no more electricity will flow

Problem can be undersized wire and breaker or mismatched wire size and breaker rating

if a circuit breaker pops i assume its an RCELD or is it a MCB type
it is some leakage to earth somewhere in the electrics
if it runs and pops the breaker
and you can plug it in and it will sit there
then i assume its something do do with the fan system
or ignitor . driver system
look for sources of leakage to earth
and you could measure the peek current it uses with a multimeter inline
set to AC amps

anyway its defo not a gonner just some bad electrics

try fitting a new plug. if you do cut back the cord back at least 3 inches try it again. before you do check socket with another appliance.let me know if that fixed it or not

Sorry cant solve this but mine did the same. Mine is almost 4 years old now. Have you found out what the problem was with yours? Have you sent it back? Nicky.

This sounds like a main control problem. More specifically like one of the relays is shorted. You will need to acess the main control and carefully inspect it for any burn marks. If you don't see any disconnect the main power supply wire going to the main control. Then plug it back in if it trips the breaker the problem is in the power cord or wiring from the cord junction to the main control. If it does not trip the breaker the problem is the main control.

the 30amp breaker is bad but when running on a 20 which is good its not enough of amps to support thats why it ran for 2hours before it ..so try changing that breaker to a new one

You must find the reason the main breaker is popping ...

I'd start by unplugging everything and remove all breakers. Turn the main on ... does it pop? If it pops here look between the breaker panel and the end of your cord. Turn the power off - reinstall the first breaker - turn power back on. What happens ... keep doing this until the main or individual breaker pops - investigate that circuit to find your short.

If you get all breakers back in with out popping anything ... start plugging stuff back in. Something is shorting somewhere.

Let me know what you find please.

thanks

So doing anything will throw the breaker? Must have a shorted wire either going to ground on the cooktop of where the cord wires in at the cook top. Dont know exactly but be looking for wiring with insulation gone and rubbing the frame or each other

motor may be getting old and consuming more pwr and exceed power given popping breaker. try another outlet,is chord ok or grounds?
