The last four of my unit is 0910...
The wires that connect to the element have a reputation for having crappy connectors and wire.
I have had mine running pretty much 2-3 times a week for 1.5 years.
The first time it quit I was able to clean them and get new connectors and drive on.
This time the element and wires burned up.
I called MB and the element is on back order for 30 days....
So I cleaned what was left of the element and cut the wires back and cleaned them.
Wrapped together and soldered. Then duct taped evreything and put it back together.
