SANTOS: User and maintenance manual
98155 EN 4.3- 05 2018 15/ 22 www.santos.fr
FAULT FINDING
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 that the On / Off switch indicator (11) lights up when the switch is in the 1
position. If not, check the following 2 points, then replace the switch.
• Check that the amperometric protector has not tripped following an overload. (See
"The machine stops as a result of a motor overload" paragraph)
• Check: the mains power supply and the condition of the power supply lead (10).
• Check that the display (19) lights up (it shows the total number of measured doses) If
not, replace the control part of the electronic module.
• Check that the 2 selector buttons are on (press one of the buttons).
• 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 (26) (fig. N) (the electric
components can be accessed without dismantling the machine), on the control panel
(19) and on the filter holder micro-switch (25).
• Check the electric components, replacing them one by one.
The machine stops as a result of motor over-heating: (the motor unit is hot)
(220V version)
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, 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 from operating.
If the machine is hot, refer to the section "The machine stops as a result of motor over-
heating").
Otherwise:
• Turn off the electric power supply (unplug the mains power lead (10))
