BREWER ERROR
The problem can be caused by bad
contact sockets from the 2 and 4
pole Molex connectors. Check if
all the socket (male/female) make
contact with each other.
The connectors are to be found
behind the left panel.
The 2 pole Molex is responsible for
the motor signal 230Vac.
The 4 pole Molex is responsible
for the position switch signals (low
voltage).
