9. Troubleshooting
9.1. The machine is not working
• Be sure it is plugged in and the circuit is working. Try another outlet if in doubt.
• Be sure both Coffee and Steam switches are turn on position ON.
9.2. No water can be pumped
• Check the Low Water Level Warning Light to see if the Water Reservoir needs to be refilled.
• Check the Water Reservoir to be sure that the tank is properly seated in the machine.
Lift it and set it back into place. You should be able to feel it compress the springs of its platform which
engage the safety switch.
• Be sure both Coffe and Steam switches are turn on position ON.
9.3. The Grouphead is not getting very warm
• The operating lever on the right side of the Grouphead must be in the fully-down position, pushed
back towards the face of the machine as far as it will go (light pressure is all that is necessary- no need
to force the lever). If it is not in this position, the water path for the thermosyphon is restricted and the
Grouphead will not reach the proper operating temperature.
• Be sure the Coffee Switch is turn on position ON.
• Check the Low Water Level Warning Light to see if the reservoir needs to be refilled.
9.4. I can pump water, but the water is always cold
• Be sure both Coffee and Steam switches are turn on position ON.
• Over Temperature Safety Thermostat tripped. This occurs if the pressurestat malfunctions or the water
level is not maintained in the boiler. In either case the boiler can overheat. To save the machine from
damage, there is an over-temperature thermostat that protects the machine much like a circuit breaker
or fuse protects the wiring in your home. And much in the same way as a circuit breaker, the over-
temperature thermostat can be reset. If you suspect that the thermostat has been tripped it is important
to verify the cause before continuing: please contact your retailer’s service department.
9.5. The Machine Stopped Suddenly in the Middle of a Pull
• Check the water level in the Water Reservoir.
9.6. The Coffee Tastes Bad
The list of causes is nearly endless. Volumes can be written on what can cause espresso to taste bad,
some of which is discussed in the general instructions.
Here are a few tips to help:
• Be sure that the coffee you are using is fresh.
• Try a different brand of coffee.
• Are you using a quality grinder and grind the beans fresh for each use?
• If you know someone who makes espresso, invite them over and let them try making espresso
with your equipment and coffee. Sometimes the smallest change in procedure can make a big
difference in taste.
