Troubleshooting
• 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)
• 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)).
• 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.
If the problem persists, turn the machine electric power off (unplug the mains power lead (10)) and call on
someone from the maintenance department or contact an approved Omcan dealer.
THE GROUND COFFEE DOSE MEASUREMENT IS NOT CONSISTENT
• Check that there are coffee beans in the bean container. It is recommended that there is a minimum of
400g of coffee beans in the hopper.
• Clean the ground coffee outlet tube (23) (fig. H).
THE MACHINE RUNS BUT WITHOUT THE FILLING FILTER HOLDER
• Check that there are coffee beans in the bean container.
• Check that the bean container shutter (6) is in the open position.
• Try with a coarser grind setting.
• Replace the grindstones (9).
THE ESPRESSO COFFEES ARE GETTING WEAKER AND WEAKER
• Check and adjust the grinding setting.
• Check and adjust the timer settings. (The timer values increase depending on the wear on the grindstones.
If the values are too high, then replace the grindstones (9).
