E06
Display shows E06 and the pump runs continuously or not at all; machine may not reach correct boiler level.
Boiler Level Probe / Autofill Circuit Error
E07
Machine displays E07 and will not brew; group head remains cold.
Group Head Temperature Sensor Fault
E08
Display shows E08; machine may shut down or limit operation, often related to steam temperature.
Steam Boiler Overtemperature / Sensor Fault
E09
Machine shows E09 and the pump does not run during brew cycles.
Pump Drive Circuit Error
E10
Display shows E10; machine may not respond to keypad or touch inputs.
User Interface / Keypad Communication Error
E11
Machine displays E11 and disables brewing; often associated with internal leak detection (if equipped).
Internal Leak / Drip Tray Sensor Fault
E12
Display shows E12; machine may not start or may shut down unexpectedly.
Mains Voltage / Power Supply Error
E13
Machine shows E13 and disables automatic dosing; volumetric shots may not stop correctly.
Volumetric Dosing / Flow Calibration Error
E14
Display shows E14; machine may not steam or may limit steam power.
Steam Pressure Sensor / Pressurestat Error
E15
Machine shows E15 and may not complete startup; often associated with communication between boards.
Internal Communication Bus Error
Symptom
Brew temperature seems inconsistent; shots sometimes sour and sometimes bitter with same settings.
Brew Temperature Instability
Symptom
Brew water has a metallic, chemical, or off taste even after flushing.
Water Quality / Contamination Issue
Symptom
Burning smell or visible smoke from machine during operation.
Electrical Overheating / Component Failure
Symptom
Display or indicator lights flicker or dim when pump or heater turns on.
Voltage Drop / Power Distribution Issue
Symptom
Drip tray fills very quickly with clear water during normal operation.
Excessive 3-Way Valve Discharge / Overfill
Symptom
High‑pitched squeal or whistle from boiler area during heating.
Boiler Scale / Pressure Relief Noise
Symptom
Hot water tap drips continuously or will not shut off completely.
Hot Water Valve Seat Wear
Symptom
Machine does not auto‑fill boiler; steam pressure drops and does not recover, but pump works for brewing.
Autofill Control Failure
Symptom
Machine is very slow to heat up; takes much longer than usual to reach operating temperature.
Reduced Heating Performance
Symptom
Machine makes loud banging or rattling noise when pump runs; vibration is excessive.
Pump Mounting / Cavitation Issue
Symptom
Machine powers on but does not heat; both brew and steam functions remain cold, no error code displayed.
Global Heating Disable / Safety Cutout
Symptom
Machine shuts off unexpectedly during use and may restart after cooling.
Thermal Overload / Overcurrent Protection
Symptom
Machine vibrates excessively on countertop during pump operation; may move or walk slightly.
Chassis Vibration / Isolation Failure
Symptom
Machine will not start a brew cycle; pressing brew button does nothing, but machine is powered and hot.
Brew Activation / Switch Fault
Symptom
No power at all – display off, no lights, machine completely dead when switched on.
Primary Power Input Failure
Symptom
No steam at all from wand; steam knob opens but nothing comes out, even though machine is hot.
Steam Wand or Valve Blockage
Symptom
Portafilter sprays or channels badly; uneven extraction even with good grinder and technique.
Uneven Water Distribution at Group
Symptom
Pump runs but no water comes out of the group head; loud buzzing from pump, dry shots, or no flow.
Brew Circuit Flow Restriction
Symptom
Steam wand produces weak steam or mostly hot water; milk takes very long to froth.
Steam Circuit Restriction / Low Boiler Pressure
Symptom
Water leaking from around the portafilter during brewing; water sprays from group gasket area.
Group Head Gasket Wear
Symptom
Water leaking from bottom of machine or inside chassis; puddle under machine.
Internal Hose or Fitting Leak
Symptom
Water leaking from group head even when not brewing; slow drip into drip tray.
3-Way Solenoid Valve Not Sealing
Symptom
Water leaking from steam wand tip even when steam knob is fully closed.
Steam Valve Seat Wear / Contamination
Symptom
Weak water flow from group head; shots run very slowly even with coarse grind and no coffee puck.
