I have just replaced the heater in my HotPoint WM72, and used Colin's guide above.
Thanks a lot Colin, it went smoothly with the guide. Very good description you have made.
I have a NB for others, who is about to replace the heater.
When you have removed the front, then remove the metalplate in front of the heater, before you try to remove the heater. It is fixed with 4 small screws and i very easy to remove. This avoids you hands from being torn to blood when you remove the heater.
Good luck every body, it is very easy to replace the heater!
