Verify 120 volts between Blu14 & WHT14
on the heating element. If yes, replace
heating element. If no, proceed to #2.
With the toggle switch turned off, remove
WHT/GRY from triac gate, and connect to
Red meter lead. Turn on toggle switch, and
place Black meter lead to Neutral and/or L1
on power block. Verify 120 volts. If yes, re-
place triac. If no, replace U.P.M.

TROUBLESHOOTING INSTRUCTIONS
Verify that the tank temperature is pro-
grammed for 200 degrees. If yes, proceed
to #2. If no, adjust accordingly.
Turn off toggle switch, and unplug the tem-
perature sensor from wiring harness. Set
dvm to read 200k ohm, and connect meter
leads to sensor connector. Sensor should
read over 100k ohm if the tank is cold, and
under 10k ohm if the tank is hot.
If the sensor is not within this range, replace
the sensor. If the sensor is within this range,
replace the UPM.

Not heating (120/220 volt):
LCD reads “Ready”
Verify 220 volts between L1-L2 on the
power block. If yes, proceed to #2. If no,
verify that the unit is plugged in correctly,
and that the panel breaker is turned on.
Verify 220 volts between #2 & #4 on the
manual reset thermostat. If yes, proceed to
#3, if no, reset or replace the manual reset
thermostat.
Verify 220 volts across the toggle switch. If
yes, proceed to #4. If no, replace the toggle
switch.
Verify 220 volts across the heating ele-
ments. If yes, proceed to #5. If no, verify
120 vac on the triac gate. If yes, replace the
triac. If no, replace the UPM.
Verify 9 ohm across each active heating
element, and replace any heating element
that reads “OPEN” or is “GROUNDED”

Verify that the resistance on the tempera-
ture sensor is less than 10k ohms with a
hot tank (200+ degrees) If no, verify correct
mounting and that the walls of the tank are
free of mineral deposits.
If yes, bypass the sensor using a jumper
with a 5k ohm resistor. If the LCD reads
“ready” and the unit stops heating, replace
the temperature sensor, if not, replace the
UPM.

Check across A-1 & A-2 of triac for continuity .
If continuity is present, replace triac, if no
continuity, replace UPM.

BREWING ISSUES
TANK FILLING ISSUES
Verify 120 volts at the inlet valve coil
Replace inlet valve
Remove orange wire from the water
Level probe. Does the tank ll?
Replace the water level probe
Replace the UPM
Turn OFF toggle switch.
Does the tank continue to ll?
Overlling: Not lling:

Yes:
No:
iEnsure correct alignment of the sprayhead
tting and that the tubing is routed properly to
allow for maximum water ow.
Ensure that the sprayhead is free of mineral
deposits, and properly connected.
LCD does not read “Brewing”:
If the LCD reads “Ready to Brew” and no
response when Brew Button is pressed, replace
the UPM
LCD reads “Brewing”:
Does water ow from the hot water faucet? If yes,
verify 120 volts at the dump valve coil. If voltage
is present at the dump valve coil, replace the
dump valve.
If okay, replace the UPM. (Verify the resistance
on the dump valve coil to be open in one direc-
tion, and under 2k ohm in the other direction
before replacing the UPM).
If water does not ow from the hot water faucet,
replace the water level probe.
Brewing Short Pots:
Verify that the dump valve outlet tting on the
tank, the tubing between the tank outlet and the
sprayhead tting, the sprayhead, and dump valve
are clear of obstructions.
Ensure correct alignment of the sprayhead tting
and that the tubing is routed properly to allow for
maximum water ow.
Verify that the hot water tank is lling correctly. If
not, replace the water level probe.
If all the above are okay, replace the dump
valve.
Overowing the Pot:
Ensure that the sprayhead has not been
removed. Replace as needed.
Ensure that the hot water tank is not overowing
(See Tank Filling Issues).
Ensure cold brew lock is set to 5 degrees.
Ensure that lime/debis are not a factor. If all the
above are okay, replace the dump valve.
