Toubleshooting : Using the Diagnostics
1. Enter programming mode by tapping the (white) Curtis logo on the touchscreen 5 times.
2. Enter the access code & press OK (default code is 1234 unless changed by store)
3. The MAIN MENU screen will appear. Press CONTROL SETTINGS.
4. Press DIAGNOSTICS. When prompted, place an empty container under the brew basket, then press OK.
5. Press a button to test the desired circuit, or press AUTO TEST to test all circuits. If a button is highlighted green then the circuit has
passed the electrical test. If the button is highlighted red, further maintenance is likely required.
a. If the circuit test fails, check to make sure that power is being supplied to the component during normal operation. If
power is supplied, and it still does not operate, replace the component. If power is not being supplied, check the wiring.
b. If a valve circuit passes the test, check for a mechanical failure by listening to the valve "click" when the test button is
pressed. To check for a failed pump, run a brew cycle and check for fluid flow through the pump.

Description
Maintenance Required
Low Water Flow
UPM-UCM have a mismatch in their
settings
Fill run error/Overflow
Open sensor
Excess temperature
UPM-UCM Communication
UPM software revision does not support
the model selected
Likely Cause
Brew count "Gallons Since Reset" exceeds programmed PM
period
The Inlet valve remains on longer than 40 seconds (during
the brew cycle only) and repeats TWICE during that brew
cycle. It should clear upon the next brew cycle and if the
same low-flow exists again, the warning will reappear.
Firmware update is needed
The water inlet valve has either been open for more than 10
minutes or the initial tank fill has been open for 120 seconds.
Break in the temperature thermistor circuit or short circuit
The sensor is reading that the temperature in the heating
tank has risen above 210 F, or the sensor has shorted out.
Break in the UPM-UCM communication circuit
The universal power module (UPM) has an old software
version and is not compatible with the brewer model in which
it has been installed
