E-Max T™ TEST PROGRAM (continued)

E. LED Test The display should read “Testing LED’s”:
Individual LED’s will be tested individually, beginning with the first on the
left, and proceeding through all six LED’s at one-second intervals.
Screen will read “Testing LED’s” during the entire test.
1. Verify that only one LED at a time is lit, and that each of the six
LED’s light in their proper sequence.
L1 L2 L3 L4 L5 L6
BREW CANCEL ON/OFF Volume 1 Volume 2 Volume 3
or “E” or “a” or “T”
2. Verify that each LED is the correct RED color:
3. When all lights have been tested, press the 3rd key (ON/OFF) to
continue.

F. Output Test The valves and heater are tested in this stage.
Display should read “Inlet 1 Off”:
1. Press the 3rd key. The inlet valve should turn on, and the display
should read “Inlet 1 ON”
2. Continue pressing the 3rd key, in sequence, to advance through the
component tests, Each component should turn ON then OFF in the
following order:
Output 1 Inlet
Output 2 Dump
Output 3 Heater
Output 4 Bypass
Output 5 (Future - not functional at this time)
Output 6 (Future - not functional at this time)
3. Each component should turn ON in order, with only one component
ON at a time. If the components fail to turn on in the proper
sequence, or if a “Valve Fault” message is displayed, the controller
has failed the test.

G. Probes Test This section ensures the proper functioning of the Water
Level Probe and Temperature Probe:
1. The left number determines whether the WATER-sensing probe is
in contact with water.
a. A number of “0” (or close to 0) means that water is in contact
with the probe.
b. A number of 255 (or close to 255) means water is not in contact
with the probe.
2. The right number represents what the reads. The table at right
is an approximate correlation between the value and the
temperature the probe is sensing. (Note a number less than 10
would indicate the probe is not properly connected to the board,
while a number higher than 155 indicate a defective probe.)

H. Test Done. Indicates completion, press ON/OFF to reset controller.
The controller should restart with the message “BLOOMFIELD”, then
return to the OFF mode.
