Eversys Coffee Machine Error Code E-107: Pressure Sensor Failure
E-107 is a steam boiler pressure sensor failure. The control cannot read a believable pressure, so it will not use steam. Skip steam and hot water, restart once, and call us if the message returns.
High: the control will not heat the steam boiler on a pressure it cannot read, so steam is out of service.

What does Eversys error code E-107 mean?
Steam safety depends on knowing the pressure inside the boiler. The control reads a pressure sensor continuously and uses that number to decide when to heat and when to stop. If the signal is missing, out of range, or does not make sense compared with what the boiler is doing, the control flags a sensor failure and shows E-107. At that point it cannot use steam safely, because it would be heating without feedback. Staff may lose steam and hot water. The owner's guide points to the pressure sensor and its cable as the first place to look. That order matters. A sensor that has died, a cable that has chafed, a loose plug at either end, and a damaged board input can each return the same bad reading. The sensor port can also gather scale or residue that disturbs the signal. The machine cannot say which of these is responsible, so a technician measures the pressure on a gauge, then follows the signal back along the cable to the board. Replacing the sensor first would be a guess, and it would leave a bad cable or input untouched. The display text for this message is E-107.
Affected models and control systems
This applies to Eversys Cameo and Enigma / Shotmaster machines showing E-xxx error messages. It concerns the steam boiler pressure sensor, not the water pressure sensor that W-016 covers.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Steam wand unavailable
- Hot water limited or unavailable
- E-107 on the display
- Steam never starts even after the machine has been on for a while
Possible causes
Listed in Eversys's documentation
- Failed steam boiler pressure sensor or damaged cable
- Loose or corroded connector at the sensor or the board
- Failed board input for the pressure signal
- Scale or residue at the sensor port
Other likely causes — what usually sits behind error code E-107 on this control. A technician confirms which one it is before any part is replaced.
- A cable run close to the boiler that has hardened and cracked from heat
- A sensor whose reading drifts out of range only when the boiler is fully hot
Safe checks before calling for service
- Skip steam and hot water while the message is showing.
- Restart once at the main switch, leaving ten seconds between off and on.
- If the message returns, keep the machine off and call us.
- The sensor and its cable sit in a hot area with mains power, so only we touch them. Write down whether E-107 showed at start-up or after heating.
How a technician diagnoses error code E-107
- Cool the machine and isolate power.
- Fit a test gauge and read true boiler pressure when the machine heats.
- Inspect the sensor, cable and both connectors for damage and residue.
- Measure the sensor signal against the pressure shown by the gauge.
- Check the board input by substituting a known-good sensor reading if available.
- Replace only the part that fails, then confirm normal pressure and steam.
- The sensor is fitted to a pressurized, hot steam boiler and cannot be removed without depressurizing and cooling it.
- Comparing the sensor signal with a test gauge takes a meter and a gauge fitting.
- The cable and board input sit near mains-powered parts behind the panels.

Is E-107 the same as W-016?
No. E-107 is the steam boiler pressure sensor. W-016 is the water pressure sensor, and it is only a warning.
Can I use the machine for coffee only?
Some drinks may still run, but steam and hot water are off. If the message stays, we recommend switching off until it is checked.
Does a restart fix a bad sensor?
A restart can clear a one-time glitch. A sensor or cable that has actually failed will bring E-107 back.
