Siemens oven trips MCB breaker?

Our Siemens HB55054GB/02 oven trips our MCB. I assume it's a heating element drawing too much current but which one as there are two elements?
I took the bottom element out and one coil is 11 ohms and infinite resistance to ground. The other is 56 ohms and 6.5m ohms to ground.
Bottom element says 1500w.
