The new heating element was delivered very quickly. Accessing it was time-consuming, though, with some screws needing a lot of work to remove. Then the legs and shield needed to be transplanted to the new one, and again frozen-solid screws made that time-consuming. After that it went together straightforwardly, but not quickly. The "20-30 mins" quoted in the part write-up seems to me to be complete fantasy, even for an expert. The machine is 10 years old.
