I had the same problem, try to wash a cold wash, if i does not JAM, them it is the heating element, or a wire that was burnd over.
The heating element cost 340 Danish crowns, about 32 £ and 50 $.
The heating element is in the front just under the door, so the whole front have to go off.
It is okay to splitt and collect again, the only one thing that was piss*ng me off, was that the heating element dident fit, but the thing that was wrong, was that you have to hit the metal clips inside the hole, and PUSH WERY WERY hard, until a click is comming, and it fits.
Hope it helps.
