TROUBLESHOOTING INSTRUCTIONS

POWER ISSUES

The unit will not turn on:

Check if the panel breaker is turned on. If it

1

is, proceed to STEP 2.

Check the voltage at the receptacle it should

2

read: L1-N = 120v, N-G = 0v. Proceed to STEP 3 if accurate.

Check if the power cord is properly con-

3

nected to the receptacle. If it is, proceed to STEP 4.

Check the toggle switch if it is in the ON

4

position. If it is ON, proceed to STEP 5.

Not heating:

LCD reads “Heating”

Yes:

Verify 120 volts between #2 & #4 on both sides of the Manual Reset Thermostat. If no, reset or replace the Manual Reset Thermostat.

Verify 120 volts across the Toggle Switch.

Yes:

If no, replace the toggle switch.

Check the voltage at the power block, it

5

should read: L1-N = 120v, N-G = 0v.

Check the voltage at the reset thermostat, it

6

should read 120v.

Check the voltage at the toggle switch, it

7

should read 120v.

Verify 120v between pins #8 and #16 on

8

molex connector at UCM.

If all steps were taken and the unit still does

9

not turn on, replace the UCM.

HEATING ISSUES

Overheating/Steaming:

LCD reads “Heating”

Verify that the resistance on the Temperature 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 UCM.

Verify 120 volts across the Heating Ele-

Yes:

ment. If yes, replace the Heating Element. If no, verify 120 volts between the Triac gate, Neutral, and L1. If yes, replace the Triac, if no, replace the UCM.

Verify that the panel breaker is turned on

No:

and the receptacle has 120 volts. If not, consult an electrician.

WARMER ISSUES

No power to any warmer:

Verify correct programming: (Model number).

Not heating:

Verify 120v at heating element. Yes: Replace heating element. No: Verify that the connections and wirings are good. If OK, replace UCM.

Service & Sales 1-800-421-6150

LCD reads “Ready to Brew”

Check the triac for continuity across A1 & A2, if continuity is present, replace the triac, if no continuity, replace UCM.

Ensure that the temperature is adjusted to compensate

i

for high elevation. The factory setting is 200 degrees. The temperature setting will need to be reduced Two degrees for every One Thousand feet of elevation.

Constantly hot, even when turned off:

Ensure proper resistence value on the heating element between 140-170 ohm.

Ensure wiring is not shorted to ground.

Replace UCM.

TROUBLESHOOTING INSTRUCTIONS

TANK FILLING ISSUES

Not lling:

Yes:

Does the LCD read “Water Level Error”?

Yes:

Verify the ow rate to be a minimum of 1 gpm from outlet of the water lter. If not,

ensure that the inlet side of the water

lter is receiving a minimum of 1 gpm. If yes, replace the water lter. If not, con-

sult a plumber.

No:

Remove the orange wire from the probe.

Does the tank start lling?

Yes:

Replace water level probe

No:

Replace the UCM

BREWING ISSUES

LCD does not read “Brewing”:

If the LCD reads “Ready to Brew” and no response when Brew Button is pressed, replace the UCM.

LCD reads “Brewing”:

No water ow from the sprayhead: 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 120 volts is not present at

the dump valve coil, conrm continuety of wiring

between molex connector and Dump Valve. If okay, replace the UCM. (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 UCM) If water does not ow

from the hot water faucet, replace the Water Level Probe.

Brewing Short Pots:

Verify that the Hot Water Tank is lling correctly.

(See Tank Filling issues)

Overlling:

Turn OFF toggle switch.

Does the tank continue to ll?

Yes: Replace water inlet valve No: Ground the probe wire to chassis.

Does the tank continue to still ll?

Yes: Replace the UCM No: Replace Water Level Probe

Before replacing any parts, verify the

i

following:

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. (No Kinks)

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 that hot water is not owing from the Dump Valve when the toggle switch is turned off. If it is, replace the dump valve.

• Ensure Cold Brew Lock is set to 5 degrees
