So... you have at least two of the three things to make your drier work (assuming it's similar to the ones here in the U.S.):
1. It heats
2. It "tumbles" - drum is turning
But you didn't mention:
3. Air movement through the drum
So, do you know where the hot air exhausts out of the house? If so, see if there's air coming out. My suspicion is, since you report the machine being hot to the touch, is that the fan supplying air into the drum isn't working. Depending on the make and model, there are a number of reasons why.
So... determine if have # 3...
