Description Message SolutionMessage

understand an instruction.
This message is displayed when the CPU does not
detect a full signal from the steam boiler within a
set time interval.

receive any signal from the Safety Probe in the
steam boiler.
This message is displayed when the CPU does not
receive the appropriate signal from the owmeter.

Most likely the machine power was disconnected without rst turning off the machine through the
keypad and display. Turn off machine using main switch. This should clear the error.
When this message is displayed the CPU also shuts down and turns the machine off. Water is not
entering the boiler. Call an authorized service technician to repair this fault.
When this message is displayed the CPU turns off power to the steam boiler heating element. The
only way to reset this error is to repair the Safety Probe to restore the signal to the CPU.
When owmeter alarm is displayed, the light on the button that initiated the brew cycle will begin
to ash. This problem is a result of water not owing through the ow meter. This can be caused
by coffee ground too ne or packed too tightly (try a coarser grind or lighter tamping) or a blockage
in the tubes, a malfunctioning water pump, a faulty valve, or a damaged owmeter. Call a service
technician to x this problem.
