THE MACHINE DOESN'T WORK • SYMPTOM : No Power • check the main electricity supply : SOLUTION = Reset power • check electrical connections : SOLUTION = Repair or replace the connection • check the central unit power supply fuse : SOLUTION = Replace the fuse • check the on/off switch and the electronic card : SOLUTION= Replace the switch of the electronic card. • check the electronics control unit : SOLUTION= Check the electronic control unit.

MACHINE DOES NOT HEAT OR IS NOT PRESSURISED • SYMPTOM : Heating Element (Resistor) Not Powered • check the correct voltage of the resistor : SOLUTION = Reset power • if the voltage is correct,check the exact polarity on the leads of the resistor : SOLUTION = Replace the resistor. • check the electrical contacts : SOLUTION = Repair or replace the contacts. • reset and check that the safety thermostat is powered : SOLUTION = Replace the safety thermostat. • make sure that the pressure switch is powered : SOLUTION = Replace the thermostat. • where envisaged,make sure that the power relay is powered : SOLUTION = Replace the relay • incorrect boiler pressure readout ( no steam ) : SOLUTION = Check the anti-vacuum system,replace as required. • check the main water supply : SOLUTION = Reset water • make sure the inlet valve is open : SOLUTION = Open the inlet valve • check the self-leveling function : SOLUTION = Replace the self-leveling probe • make sure that the self-leveling probe is powered and that the internal piston is not obstructed : SOLUTION = If not, make sure that the appropriate fuse in the main control unit is working properly, otherwise replace. • check the retainer valve : SOLUTION = Clean the valve and replace the seal. • SYMPTOM : Too Much Water In The Boiler. • check the auto-level solenoid for leaks : SOLUTION = Replace the auto-level solenoid • check the auto-level solenoid voltage : SOLUTION = If not working correctly' replace it. If it is working, check ( clean ) the auto-level probe.Check the control unit. • check the manual filling valve for leaks : SOLUTION = Replace the valve • check the heat exchanger for leaks : SOLUTION = Replace the boiler • check the auto-level valve : SOLUTION = Replace the self-leveling probe.

NO WATER DELIVERY THROUGH THE SUPPLY UNIT • SYMPTOM : Loss Of Water • check the main water supply : SOLUTION = Reset water • make sure the inlet valve is open : SOLUTION = Open the water inlet valve • SYMPTOM : Loss Of Power In The Supply Circuit • make sure that the 3-way solenoid is powered • check the supply circuit button : SOLUTION = Replace the main electronic card or the " dashboard " card. • SYMPTOM : Physical Blockage ( Caused By Deposits Or Unusual ) • check girl clamping : SOLUTION = Check girl clamping • check the 3-way solenoid support clamping : SOLUTION = Clean or replace it • check the 3-way solenoid clamping : SOLUTION = Clean or replace it • check the connection holes between the sprays and the pre-infusion chamber, the 3-way valve and the gigleur : SOLUTION = Clean • check the secondary retainer valve in the coffee circuit : SOLUTION = Replace it • check the heat exchanger clamping : SOLUTION = Clean it • check the doser-gigleur clamping : SOLUTION = Clean or replace it • SYMPTOM : Pump • make sure that pressure is correct ( 7-9 bar ) : SOLUTION = Replace the pump • check pump rotation : SOLUTION = Release or replace it • make sure the motor is powered :

INCONSISTENT COFFEE DELIVERY • SYMPTOM : Continuous Delivery • check the electrical connections of the doser : SOLUTION = Clean and reconnect or Replace the doser. If the doser causes impulses, replace the electronic control card. • SYMPTOM : Inconsistent Delivery ( Long ) • make sure that the doser generates impulses : SOLUTION = Replace the doser. If the doser causes impulses, replace the electronic card. • SYMPTOM : Inconsistent Supply ( Short ) • check the expansion valve ( neplax ) for leaks through the supply unit during delivery : SOLUTION = Remove, clean or replace the gasket. • check the 3-way valve for leaks through the supply unit during delivery : SOLUTION = Replace the 3-way solenoid. • check the retainer valve : SOLUTION = Clean or replace the gasket. • SYMPTOM : Too Slow • sprays blocked : SOLUTION = Replace them • coffee too light in color : SOLUTION = Adjust the grinding ( grinder doser ). • gigleur clogged : SOLUTION = Clean or replace it • pump pressure too low  : SOLUTION = Adjust pump pressure ( 7-9 bar ) . Replace the pump. • check the heat exchanger , the pipes and the gigleur for obstructions : SOLUTION = Change the pipes, clean the heat exchanger with acid, clean the unit, check the function of the water depurator. • SYMPTOM : Too Fast • coffee doses to small : SOLUTION = Adjust the coffee dose • grinding to large : SOLUTION = Adjust the setting of the grinder-doser • pump pressure too high : SOLUTION = Adjust pump pressure ( 7-9 bar ). Replace the pump • SYMPTOM : Leaks Around The Filter-Holder • check underneath the sheath of the filter : SOLUTION = Replace it • check the edge of the filter : SOLUTION = Replace it

STEAM VALVE • SYMPTOM : Loss Of Steam • check the valve casings : SOLUTION = Clean the valves and replace the sheaths. • SYMPTOM : No Steam • check the steam sprayers : SOLUTIONS = Clean or replace them. ALSO SEE:    ( machine does not heat or is not pressurized ). HOT WATER VALVE • SYMPTOM : Loss Of Water ( Manual ) • check the valve seals : SOLUTION = Clean the valves and replace the seals. • SYMPTOM : Loss Of Water ( Automatic ) • check the solenoid voltage.                                   • SYMPTOM : No Water ( Automatic ) • check the solenoid voltage • SYMPTOM : No Water - Only Steam • check the water level in the boiler : SOLUTION = ALSO SEE : " ( Machine does not heat or is not pressurized )" and " ( Water leaks ) "

WET COFFEE GROUNDS ( AFTER DELIVERY ) • SYMPTOM : Delivery Water To Cold • check the water economy valve , if fitted : SOLUTION = Adjust the flow using the knob. Replace it • SYMPTOM : Water Leaks From The Coffee Grounds In The Filter-Holder After Infusion • check the position of the blower ( Mac Cup & Program ) : SOLUTION = Fit the blower correctly • check the 3-way solenoid discharge : SOLUTION = Clean or replace it • check the pipe routing from the sprayers to the 3-way solenoid : SOLUTION = Clean • check the temperature of the unit ( external 80-85 degrees C ) • check the coffee dose : SOLUTION = Adjust the coffee dose ( grinder-doser ) • check the coffee grinding : SOLUTION = Adjust the setting of the grinder-doser • check the coffee pressing : SOLUTION = Inform the user about the correct pressure of the coffee dose
