Troubleshooting
15. Unscrew the “adjustment nut” (5) by 5 to 10 notches.
16. With coffee, adjust the ground coffee setting (see “Coffee grinding adjustment” section).
Carefully determine the reason for the machine stopping.
In all circumstances, if the problem persists, disconnect the electric power supply (unplug the mains supply
lead plug (10)) and call on someone from the maintenance department or contact an approved SANTOS
dealer.
Where appropriate, do not forget to close the bean container shutter (6) before removing the container.
THE MACHINE WILL NOT START
• Check: the mains power supply and the condition of the power supply lead (10).
• Check that the On / Off switch indicator (11) lights up when the switch is in the 1 position. If not, replace the
switch.
• Check that the grindstones (9) are not making contact preventing the motor from starting.
• Check that there are no foreign bodies stuck between the grindstones.
• Inside the machine, check the condition of the electric wiring and the connections (on the switch (11), on
the component support module (20) (fig. N) (the electric components can be accessed without dismantling
the machine) and on the dose measurer automatic device unit (19) (fig. M)).
• Check the electric components, replacing them one by one.
THE MACHINE STOPS AS A RESULT OF MOTOR OVER-HEATING: (THE MOTOR UNIT IS HOT)
The motor is protected by an integral thermal protection. If the motor overheats, it stops.
• Check that there are still coffee beans in the bean container (2).
• Put the On / Off switch (11) to the 0 position and unplug the machine.
• Wait for the motor to cool down (20 to 45 minutes) then press the On / Off switch (11) (position 1).
THE MACHINE STOPS AS A RESULT OF AN OVERLOAD
A foreign body between the grindstones, grindstones making contact, a too fine coffee grinding or intensive
operation may result in a motor overload. Under these circumstances, either the thermal protection or the
excess current protection may be activated and stop the machine operating. If the machine is hot, refer to the
section “The machine stops as a result of motor over-heating”).
• Turn off the electric power supply (unplug the mains power lead (10)).
• Move the On / Off switch (11) to the 0 position.
• Under the machine (fig. O), press the button (13) to reset the excess current protection. If the button does
not remain in the “reset” position, allow the machine to cool down before repeating the operation.
THE MACHINE STOPS A FEW MINUTES AFTER STARTING
• Check the electric components (start relay).
