[Opera-CONNIE] Fwd: Pump picture

[Guillermo Fernandez]

It could be the fuse. If we decide to go ahead with that:

the procedure for accessing the baking pump is on manual "HiCube 80 Eco", page 24. The procedure has 6 steps, but the first three ones should be enough to reach the fuse box at the top of the backing pump. It requires to remove the top part of the pump case attached to the turbo pump. 
The backing pump manual is MVP 015-2, and the description of the fuses are in page 16.

It would be nice to get familiar with the different components that appear in those pages, and be sure we have the necessary tools.
