Quick Boiler B3 Keeps tripping my shorepower

[AFKASAP]

Hi there?

My Quick Boiler B3 Keeps tripping my shorepower. It has been working fine until a few days ago.

I was able to flip the breaker back up and after a could of attempts it would work again. But now it simple won't work. It trips any plugsucket I plug it into.

Please can I have some tips on how to diagnose the problem.

Model B32512S

a short in the heating element?

I don't know the internal workings of a breaker, but have noticed that after several trippings, the breaker no longer will carry a full rated load.

Most breakers are thermal activated, and after a few trips, the contacts get pitted and this lowers the current required to trip them, also, a loose connection might get hot and carry the heat into the breaker.
If it's always the same breaker, I would suspect it, if it's a different breaker, I would suspect the heating element.

Thanks guys. The heating eliment burnt out when the boiler ran dry after the water tank became empty
