TROUBLESHOOTING INSTRUCTIONS

HEATING ISSUES

Not heating (120 volt):

LCD reads “Heating”

Verify 120 volts between Blu14 & WHT14

1

on the heating element. If yes, replace heating element. If no, proceed to #2.

With the toggle switch turned off, remove

2

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, replace triac. If no, replace U.P.M.

Not heating (220 volt):

LCD reads “Heating”

Verify 220 volts between L1-L2 on the

1

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

2

manual reset thermostat. If yes, proceed to #3, if no, reset or replace the manual reset thermostat.

Not heating (120/220 volt):

LCD reads “Ready”

Verify that the tank temperature is pro-

1

grammed for 200 degrees. If yes, proceed to #2. If no, adjust accordingly.

Turn off toggle switch, and unplug the tem-

2

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

3

the sensor. If the sensor is within this range, replace the UPM.

Overheating (120/220 volt):

LCD reads “Heating”

Verify that the resistance on the tempera-

1

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.

Verify 220 volts across the toggle switch. If

3

yes, proceed to #4. If no, replace the toggle switch.

Verify 220 volts across the heating ele-

4

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”

Service & Sales 1-800-421-6150

If yes, bypass the sensor using a jumper

2

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 “Ready”

Check across A-1 & A-2 of triac for continuity

1

If continuity is present, replace triac, if no continuity, replace UPM.

TROUBLESHOOTING INSTRUCTIONS

TANK FILLING ISSUES

Overlling:

Turn OFF toggle switch.

Does the tank continue to ll?

Replace water inlet valve

Yes:

Remove the orange wire from the

No:

water level probe and connect it to

ground. Does the tank stop lling?

Replace the water level probe

Yes:

Replace the UPM

No:

BREWING ISSUES

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 direction, and under 2k ohm in the other direction before replacing the UPM).

Not lling:

Yes:

Verify 120 volts at the inlet valve coil

Yes:

Replace inlet valve

No:

Remove orange wire from the water

Level probe. Does the tank ll?

Yes:

Replace the water level probe

No:

Replace the UPM

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.

If water does not ow from the hot water faucet,

replace the water level probe.

Ensure correct alignment of the sprayhead

i

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.

Service & Sales 1-800-421-6150

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.
