OPERATING INSTRUCTIONS (continued)
12. View Filter Statistics:
To view filter statistics, turn the brewer off. Press and hold the 1st key
(Brew), and depress the 3rd (ON/OFF) key. Total water volume will be displayed (TotalVol.).
Press the 3rd key to view the Filter Life (FltrLife:). Press the 3rd key to view the percentage of the
filter that has been used. (If the filter option is used, the filter life volume needs to be entered in
the program – see E-Max Programming Manual, Service & Counters Menu.)
13. Diagnostic Messages – Programmed Safety Features:
When E-Max T senses a problem, it
will automatically turn off all elements and valves, flash lights, display the message “Call For
Service” and display one of the messages below. (Additionally: a service phone number may
appear if it has been programmed into the system.)
* To reset the brewer it can be re-energized (or press and hold CANCEL for 3 seconds for all faults
except the Valve Fault, which must be reset by re-energizing). The brewer will try to re-start, but if the
same problem persists, the appropriate error message will appear again. Consult the Trouble Shooting
section to determine how to solve the problem.
A. “Probe/Heater Error”:
Overheating Detection (1): If the heating element is on for 5 minutes and the
temperature does not change by +2°F (1°C) in the five minute period, the unit will go into the Over Tem
-
perature Mode with all lights flashing. When in this mode the brewer turns off the heating elements, the
solenoid valves are turned off; the switches disabled; (and all lights flashing continuously). The LCD dis
-
play will read
“Probe/Heater Error”
, followed by the message
“Call for Service”
, and then the service
phone number (if it has been entered into memory). To reset press and hold CANCEL for 3 seconds, or
re-energize the brewer. (Possible causes of problem: high limit needs to be re-set; defective high limit,
element, triac, water level probe or control board.)
B. “Overheat Error”:
Overheating Detection (2): If the E-Max senses a temperature over the Maximum
Temperature set in the program (factory set at 208ºF or 98ºC) it will go into the over temperature mode
as above with all lights flashing, except the LCD will read
“overheat error”
, and
“Call for Service”
. To
reset press and hold CANCEL for 3 seconds, or re-energize the brewer. (Possible cause of problem is a
defective triac, temperature probe or related wiring and connections.)
C. “No Water Sensed” — Time-Out —Inlet Valve:
When filling for the first time, the inlet valve will remain
open for 4¼ minutes, (the screen will read
“filling…”
). If water is not detected at the end of this time
the E-Max will shut down with the message
“no water sensed”
. The valves and all elements are turned
off, and the Brew and Power light flash alternately with the Heat light, until the brewer is reset. To reset
press and hold CANCEL for 3 seconds, or re-energize the brewer. (Possible causes of the problem are:
no incoming water; slow flow of incoming water (i.e. less than 45 oz/minute); sensor not reading (check
for placement, connections or lime scale).
D. “No Water Sensed” — Time-Out – Brew Valve:
During the brew the inlet solenoid valve cycles on
intermittently to maintain the proper level in the tank. If the valve is open for 60 seconds without water
being detected at the proper level, the brewer will go into the same error mode as above (
“no water
sensed”
). To reset press and hold CANCEL for 3 seconds, or re-energize the brewer. (Possible causes
of the problem are: no incoming water; slow flow of incoming water, sensor not reading, etc.).
E. Keyswitch Locked:
If a key switch is depressed for 10 seconds this error message will occur. Lights
will flash alternately and the brewer will turn off all valves and elements. Press and hold the CANCEL
key for 3 seconds to reset the brewer (or re-energize the brewer). If the problem re-occurs this indicates
a defective switch on the key pad.
F. “Valve Fault”- Faulty Valve Detection:
When an electric or switching problem is detected with either
the inlet or brew valve the brewer turns off all elements and valves and displays
“valve fault…”
. All of
the lights will be turned on. Before re-setting the brewer the valves must be checked to determine the
problem. The brewer must be re-energized to re-set, (pressing CANCEL for 3 seconds will not reset a
valve fault).
