1.- ERROR LIST
1.1 Front cover not fitted correctly.
The display will show the following image:
The front cover has a magnet attached on the top. Once fitted in its position, the sensor placed
inside the hopper track base closes the safety circuit. The error message will then disappear,
allowing you to operate the machine.
1.1.1 Check that the magnet is on the front cover. If not there, replace the front cover.
1.1.2 If the magnet is on the front cover, disassemble the hopper track lid following the instructions
to open the machine from step #2. Once open, check there is electric continuity between
