Installation (continued)
1. HOPPERS: Depress the door latch on the left
side of the door and pull door open to access
the hoppers.
• The hoppers hold up to 14 lbs. (14 kg) of
Cappuccino product and up to 1.5 lbs. (0.7kg) of
freeze dried coffee product, depending on
model.
• To remove the hoppers swing the top
compartment door open and lift out the
hoppers.
• To reposition the hoppers in the
compartment, slide the hopper base back
between the rails until the 1/4" pin at the
bottom of the hopper base falls into the 1/4"
positioning hole of the compartment base
cover.
2. RINSE SWITCH: With the door open, the rinse
switch is located on the left side of the first
Whipper chamber.
• In the RINSE position, it disengages the
hopper motors and allows only water to be
dispensed.
• It is used for flushing out the Whipper
Chambers and to adjust the water dispense
valves for proper flow rates.
3. HEATER SWITCH: This switch is located inside
the cabinet behind the right hopper. Open door
and remove right hopper to access it.
• Its primary function is to shut off the heating
element during the initial priming, start-up
operation of the machine, or whenever the
tank is being drained for service.
Note: The Power Switch and Heater Switch must
be ON in order for the elements to operate.
4. POWER SWITCH: This switch is located on the
left side of the splash panel below the door. On
120V, 1.8 KW and 120/240 or 240V, 3 KW single
element machines the power switch controls all
power to the machine including the heater
elements.
Note: On 120/240V, 6 KW machines, the Power and
Heater Switches are independent of each other.
Both switches must be OFF in order for the
machine to be completely shut down.
5. WATER LEVEL CONTROLS: Under normal
conditions and operation, the water level in the
tank should not drop more than 1/2" (1.3cm)
from the probe. If it does, the tank is not
refilling fast enough. Check the water line and
water filter; they may need cleaning or
replacing.

Start-up Procedure
NOTICE: Make sure that the Heater Switch, located
behind right hopper with door opened, is in the OFF
position.
1. Connect the 1/4" dia. copper waterline to the
1/4" flare water inlet fitting of the valve.
2. Plug the power cord(s) into a proper receptacle.
Note: GB8M10 units use two power cords. Each cord
must be plugged into a separate receptacle.
3. Activate the Power Switch (Toggle Up). The
door display panel, the red power indicator
light and the green dispense buttons will light
up and the tank will start filling. Allow
approximately 4-5 minutes for the tank to fill.
4. Activate the Heater Switch. Allow
approximately 10-30 minutes for the water to
reach a temperature of 190°F (88°C). The heat
up time will depend on the water inlet
temperature, the input voltage, and the
wattage of the elements in the machine.
5. Place a 8 oz. (240ml) or larger cup under the left
dispense nozzle, press and hold the left
dispense switch for 6 seconds. The machine will
dispense water at the rate of 1 oz. (30ml) per
second. Repeat it several times to check for
consistent output. Repeat same for the other
dispense switches. This procedure checks that
the dispense valves are not air-locked.
6. While the tank is heating, remove the hoppers,
load them with products, and reposition them
back in the machine. When the green ready
light comes on, the tank has reached its brew
temperature and the machine is ready to

Component Tests
Dual Probe Test
If lack of water persists, check the probe as follows:
1. Turn on the power and water supply.
2. Check inside the tank to make sure the water is
below the Probe.
3. Pull the BLUE wire and terminal OFF the Probe rod.
If water still does not flow after the wire is
disconnected from the Probe, the problem may be
in the Tank Control Board.
4. If water starts flowing into the tank, the Probe may
be grounded, due to excessive liming. Check with
Ohm meter. Clean probe.
Water Inlet Valve Test
1. Turn power OFF. If the water level rises inside a
partially filled tank, the Water Inlet Valve is leaking.
2. Disconnect wires from the Water Inlet Valve coil and
connect a 2 wire line cord to the terminals. Plug it
into a 115V outlet. If water flows in and stops when
you pull it out, the Valve is working correctly.
Repeat this test a few times. The problem may be
in the Probe or Water Level Control Board.
3. If the water does not flow in when the cord is
plugged into an electrical outlet, the Solenoid coil
may be damaged, opened or the valve may have an
obstruction preventing the water from flowing in.
Clean or replace it.
Out of Product Sensor Test
1. Remove Hopper from cabinet, place the palm of
your hand up against the 1 inch diameter round
sensor at the back of the hopper chamber.
2. Listen for relay clicking on and off as you move your
hand towards and away from the sensor.
3 If relay clicks, system is operating OK.
4 Replace with a full hopper and listen for the relay
click.
5 If all this checks out and the out of product light
does not go off, then there must be defective
wiring. See wiring diagram.
Dual Probe Liquid Level Controller Test
(For models manufactured 2015 and prior)
Check the Controller as follows:
1. Make sure there is power input to the Controller at
the terminals AC1 & AC2
Your voltmeter should read 115 Volts. It should read
the same at terminals AC1 & FILL when the water
level is low. This is the output power to actuate the
coil of the Solenoid Valve to open it. The lack of
voltage at terminals AC1 & L-LEVEL or H-LEVEL
indicates that the Controller is not working
properly.
2. Make sure all wire connections are tight, including
ground.
3. If after this, the Controller is still failing to open the
Water Inlet Valve, replace it.
