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.

Overheating (120/220 volt):

LCD reads “Heating”

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:

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.
