INSTALLATION INFORMATION

ELECTRICAL SUPPLY REQUIREMENTS

WARNING

Electrical Shock Hazard

• A 115 Volt, 60 Hz, AC only 15 ampere electrical
supply, properly grounded in accordance
with the National Electrical Code and local
codes and ordinances, is required.

• It is recommended that a separate circuit,
serving only the ice maker, be provided. Use
a receptacle which cannot be turned off by a
switch or pull chain.

Plug into a grounded 3 prong outlet.

Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

Failure to follow these instructions can
result in death, fire, or electrical shock.

Before you move the ice maker into its final
location, it is important to make sure you have
the proper electrical connection:

Recommended Grounding Method

For personal safety, this appliance must be
grounded. This appliance is equipped with a
power supply cord having a 3-prong grounding
plug. To minimize possible shock hazard, the
cord must be plugged into a mating, 3- prong,
grounding-type wall receptacle, grounded in
accordance with the National Electrical Code
and local codes and ordinances. If a mating
wall receptacle is not available, it is the per­sonal responsibility of the customer to have a
properly grounded, 3-prong wall receptacle
installed by a qualified electrician.

2-1

WATER SUPPLY AND DRAIN CONNECTIONS

CONNECTING THE WATER LINE

1. Turn off the main water supply.

2. Turn on the nearest faucet and allow it to
run long enough to clear line of water.

3. Find a 1/2″ (12.70 mm) to 1-1/4″ (3.18 cm)
vertical cold water pipe near the ice maker.

NOTE: A horizontal pipe will work, but drill on
the top side of the pipe, not the bottom. This will
keep water away from the drill motor, and also
keeps normal sediment from collecting in the
valve.

4. Using a grounded drill, drill a 1/4″ (6.35 mm)
hole in the cold water pipe you have se­lected.

5. Fasten a shutoff valve to the cold water
pipe with a pipe clamp. Make sure that the
outlet end is firmly in the 1/4″ (6.35 mm)
drilled hole, and that the washer is under
the pipe clamp.

IMPORTANT: Do not use a piercing-type, or a
3/16″ (4.76 mm) saddle-type valve. These can
reduce water flow and easily become clogged.

8. Use 1/4″ (6.35 mm) O.D. copper tubing for

the cold water supply and:

a)Measure from the connection at the

back of the ice maker to the cold water
pipe.

b)Add an extra 36″ (91.4 cm) to ensure

that you have the proper length. Make
sure both ends of the copper tubing are
cut square.

c) Slip a compression sleeve and com-

pression nut over the ends of the cop­per tubing.

d)Insert the end of tubing into the water

shutoff outlet as far as it will go, and
screw the compression nut onto the
outlet. Tighten the compression nut with
an adjustable wrench, but do not over­tighten it.

9. Place the free end of the copper tubing
into a container or sink, and turn on the
main water supply. Flush the tubing until
water is clear, and then turn off the shutoff
valve on the water pipe. NOTE: Always
drain the water line before making the final
connection to the inlet of the water valve to
prevent a possible water valve malfunc­tion.

1. Cold Water Pipe 5. Compression Nut

2. Pipe Clamp 6. Compression Sleeve

3. Copper Tubing 7. Shutoff Valve

4. Coupling (purchased) 8. Packing Nut

6. Tighten the packing nut.

7. Tighten the pipe clamp screws carefully
and evenly so that the washer makes a
watertight seal. Do not overtighten the
pipe clamp. If the water line is soft copper
tubing, you could crush it.

10. Bend the copper tubing to meet the water
line inlet, located on the back of the ice
maker cabinet, as shown below.

1. Drain Hose (Drain Pump models only)

2. Vent Hose (Drain Pump models only)

3. Water Supply Line

2-2

11. Thread the nut onto the coupling at the
end of the copper tubing. Tighten the nut
by hand. Then tighten it with a wrench two
more turns. Do not overtighten.

CONNECTING THE DRAIN

Gravity Drain System

Connect the ice maker drain so that it is in
accordance with all state and local codes and
ordinances. If the ice maker is provided with a
gravity drain system, use the following guide­lines when installing the drain lines. This will
prevent water from flowing back into the ice
maker storage bin and onto the floor, causing
water damage.

1. Line to ice maker 3. Ferrule (purchased)

2. Nut (purchased) 4. Coupling (purchased)

12. Remove the four screws from the lower
access panel and remove the panel from
the front of the ice maker.

NOTE: To prevent rattling, keep the copper
tubing from touching the cabinet side wall, or
any other parts inside the cabinet.

FRONT VIEW

• Drain lines must have a minimum of 5/8″

(15.88 mm) inside diameter.

• Drain lines must have a 1″ drop per 48″ (2.54 cm
drop per 122 cm) of run, or 1/4″ drop per 12″
(6.35 mm per 30.48 cm) and not have any
low points where water can settle.

• The floor drains must be large enough to
accommodate drainage from all drains.

• The ideal installation has a standpipe with a
1-1/2″ (3.81 cm) to 2″ (5.08 cm) PVC drain
reducer installed directly below the outlet of
the drain tube, as shown. You must maintain
a 1″ (2.54 cm) air gap between the drain
hose and the standpipe.

• It may be desirable to insulate the drain line
up to the drain inlet.

SIDE VIEW

1. Water Pan Drain

2. Water Valve

13. Turn the shutoff valve ON.

14. Check the water connections for leaks,
and carefully tighten any that are leaking.

15. Reinstall the lower access panel with its
four screws.

1. Drain Hose

2. 1″ (2.54 cm) Air Gap

3. PVC Drain Reducer

4. Center of drain should be 23″ (58.4 cm) from
front of door, with or without the 3/4″ (1.91 cm)
panel on the door.

2-3

After ensuring that the drain system is ad­equate, use the following steps to properly
place the ice maker:

1. Plug in the ice maker or reconnect power.

Drain Pump System (On Some Models)

Connect the drain pump hose (provided with
the product) to the drain in accordance with all
state and local codes and ordinances.

2. Recheck the ice maker and make sure
that it is level.

3. Push the ice maker into position so that
the drain tube is positioned over the PVC
drain reducer.

4. If it is required by the local sanitation code,
seal the cabinet to the floor with an ap­proved caulking compound after all water
and electrical connections have been
made.

NOTE: If the drain hose becomes twisted and
water cannot drain, the ice maker will not oper­ate.

2-4

THEORY OF OPERATION

OPERATING SYSTEMS

There are three operating systems in the ice
maker:

• Refrigeration System

• Water System

• Electrical System

REFRIGERATION SYSTEM

The refrigeration system in the ice maker is
very similar to the system used in other refrig­eration appliances. The refrigerant used in this
unit is R134a.

There are two very important additions to the
refrigeration system in the ice maker: the Hot
Gas Valve, and the Condenser Accumulator
Tube. The components operate as follows:

• Hot Gas Valve - Allows high pressure
refrigerant gas to bypass the condenser
and flow through the condenser accu­mulator tube.

• Condenser Accumulator Tube - Hot gas
pushes liquid refrigerant through the ac­cumulator tube into the evaporator,
helping to evenly heat the evaporator
plate so that the ice slab releases
quickly and evenly.

3-1

WATER SYSTEM

The water system provides:

• Fresh water for ice production

• Water recirculation as ice is produced

The water system also flushes away minerals
and contaminates, circulates cleaning solution
during the clean cycle, and provides drainage.

The hardness of the water supplied to the ice
maker will affect the quality of the ice that is
produced. It may also affect the operation of
the water system.

Water Distributor

Evaporator

A water softener, or polyphosphate feeder, will
not cure all of the problems associated with
hard water, but they can be used to reduce
scale buildup in the ice maker. NOTE: Some
polyphosphate feeders will cause a slime
buildup in the water system when the water
supply has a low mineral content.

ELECTRICAL SYSTEM

The ice maker’s electrical system provides
power for the refrigeration and water systems,
and controls the operational cycling.

3-3

OPERATIONAL CYCLES

There are three main operational cycles for the
ice maker (more detailed operation is found in
the flow chart on page 6-5):

• Ice Making

• Harvest

• Diagnostics/Clean

ICE MAKING CYCLE

In addition, there are two possible “Off” cycles
for the ice maker. They occur when:

1. The bin is full of ice and the service
control switch is turned “ON” (Idle
mode).

2. The service control switch is turned
“OFF” while power is still supplied to
the unit.

Electrical System

Power is supplied through the service control
switches to the primary side of the voltage
step-down transformer, (120 VAC reduced to

8.7 VAC for the cutter grid and the bin light),
and the electronic control board. The elec­tronic control board in turn supplies 120 VAC to
the water recirculating pump, water inlet valve,
hot gas solenoid, condenser fan motor, and
compressor. An evaporator thermistor sup­plies temperature information to the electronic
control.

Refrigeration System

The hot gas refrigerant, under high pressure, is
forced through the condenser, where it changes
into a liquid, and flows through the drier and
capillary tube into the evaporator. Under low
pressure in the evaporator, the liquid refriger­ant absorbs heat from the water flowing over
the evaporator. The refrigerant evaporates into
a gas, and passes into the accumulator. As a
low pressure gas, the refrigerant flows back
through the suction line of the heat exchanger,
to the compressor.

During the Ice Making cycle, some of the hot
gas that is in the condenser accumulating tube,
condenses to a liquid, and remains in the
accumulating tube.

During the later stages of the Ice Making cycle,
as the ice slab forms on the evaporator freez­ing plate, some of the refrigerant passing
through the evaporator will not evaporate into
a gas, but will remain a liquid. This liquid
refrigerant will settle in the accumulator, while
the refrigerant vapor is sucked off through the
suction tube at the top of the accumulator. This
accumulated liquid refrigerant will eventually
be evaporated by the warmed refrigerant gas
passing through the accumulator during the
Harvest cycle, and during the beginning of the
next Ice Making cycle.

NOTE: It is very important that the accumulator
is not tilted out of a horizontal position. If
moved, it could cause compressor failure.

Water System

The water recirculating pump moves the water
from the reservoir pan up to the distributor,
where it flows out over the evaporator freezing
plate.

Water that does not freeze on the evaporator
plate runs off the front edge, and falls back into
the reservoir, where it is recirculated back to
the water distributor.

As the ice slab forms, the minerals in the water
are on the surface of the ice. The water flowing
over the top of the ice slab washes these miner­als back into the water reservoir pan. The water
continues to recirculate until the ice slab reaches
the set thickness. Thickness is determined by
the placement of the P4 jumper, located on the
control board.

Control board #6100499 with Code Date MGR/
0245 (45th week, 2002), or higher, will allow ice
thickness adjustments (see “Adjusting The Ice
Thickness” on page 8-3).

3-4

HARVEST CYCLE

Electrical System

When the set temperature of the evaporator
thermistor is reached, it signals the electronic
control to terminate power to the condenser
fan, and the water recirculating pump. Power is
then supplied to the hot gas valve and water fill
valve solenoids.

If the evaporator thermistor is unplugged, the
control defaults to the maximum freeze and
harvest times.

Refrigeration System

The hot gas valve opens, allowing high pres­sure refrigerant gas to bypass the condenser,
and flow through the condenser accumulating
tube. The hot gas pushes the liquid refrigerant
that has accumulated in the accumulator tube
up into the evaporator. The hot liquid refriger­ant evenly heats the evaporator plate so that
the ice slab releases quickly and evenly.

The ice slab, when released, slides off of the
evaporator plate onto the cutter grid.

Water System

The water valve opens, allowing water to flow
into the water reservoir pan. As the reservoir
fills, the mineral-laden water from the previous
Ice Making cycle, is flushed out the overflow
tube.

As a result of the hot gas flow and the ice sliding
off the evaporator plate, the evaporator tem­perature begins to rise. When the evaporator
thermistor reaches the set temperature (6.5°F),
the unit switches to the Ice Making cycle. This
cycling between Ice Making and Harvest, con­tinues until the ice bin is full.

The electronic control board controls the vari­ous components and systems in the ice maker
for each of the Ice Making and Harvest cycles.

When the ice maker’s service control switch is
in the “On” position, and the bin is not full of ice,
the evaporator thermistor determines whether
the unit will be in the Ice Making, or the Harvest
cycle.

If the thermistor is unplugged from the control
board, the unit will cycle using maximum freeze
and harvest times.

DIAGNOSTICS / CLEAN CYCLE

Electrical System

Power is supplied to the electrical components
through the service control switch.

The electronic control board controls the vari­ous components and systems during the Diag­nostics/Clean cycle. During the first 25 sec­onds of the cycle, each component will operate
for 5 seconds.

For the order of the components cycled, see
the flow chart on page 6-5.

Water System

When the service control switch is in the ‘’Clean”
position, the water recirculating pump circu­lates the cleaning solution that has been added
to the reservoir, up to the water distributor,
across the evaporator, and back into the reser­voir, where it is recirculated.

3-5

NEW ICE MAKER CONTROL BOARD (#6100499)

NOTE: Due to a quality improvement, the new
control board will replace the older design
(#2185947).

If you are replacing control board #2185947,
please read the improvements listed below. If
you are replacing control board #6100499, you
may disregard the following information.

There are no differences in mounting or wiring
the new control board. Improvements were
made to support low voltage applications.

Additional improvements include the following:

• A 15-minute minimum, and 25-minute
maximum, ice making cycle time limit.
This eliminates the production of ice slabs
that are too thin or too thick. Control
boards with Code Date MGR/0245, (45th
week, 2002), or higher, will allow ice
thickness adjustments by moving the
jumper at P4 (see “Adjusting The Ice
Thickness” on page 8-3).

• During a harvest, the water valve “on
time” is now limited to 1 minute to reduce
water usage. This also eliminates the
condition of the water valve being ener­gized for an unlimited amount of time if
the evaporator thermistor is not located
correctly, or if the reversing valve has
failed or is unplugged. If the evaporator
thermistor is unplugged, a 25-minute de­fault freeze, and 4-minute harvest inter­val will occur.

If the unit stays in harvest mode for more
than 16 minutes, the unit will go into a
failure mode, shutting the unit down, and
flashing the LED light. To get out of failure
mode, shut the unit off, and then back on
again. This will reset the control board. If
the failure was not corrected, the unit will
return to failure mode when the unit
reaches it’s 16-minute cycle again. If this
occurs, find the cause of the failure, and
repair it, then unplug the unit to reset the
board.

• The diagnostic mode sequence was
changed, moving the bin and evaporator
thermistor checks to the beginning of the
sequence. The old boards had these
checks at the end of the sequence.

• Whenever the unit has reached a failure
mode, the LED will flash, and the unit will
shut down. If the failure was caused dur­ing a harvest cycle which lasted more
than 16 minutes, the LED will remain
flashing on & off in half-second incre­ments. If the failure is caused by a faulty
bin thermistor, (not detected), the LED
will remain flashing on & off in 1-second
increments. These are the only two fail­ures that cause the unit to reach a shut­down failure mode.

• During the Clean cycle, the control board
performs the diagnostics first. If the bin
thermistor is not detected, the LED will
flash two times. This is followed by a
3-second delay. If the evaporator ther­mistor is not detected, the LED will flash
on five times. This will be followed by a
3-second delay. The LED will then come
back on, and remain on for the remainder
of the Clean cycle, and until the unit is
turned back on.

The following check can be done on the
board & thermistors:

- Unplug either thermistor electrical

MODELS WITH INTERNAL DRAIN PUMPS

The power cord on the internal drain pump is
connected to a 120 VAC wall outlet. The ice
maker is then connected to the 120 VAC outlet
on the drain pump. If the drain pump fails, or if
the drain becomes blocked, power is shut off to
the 120 VAC outlet on the drain pump.

When the unit is first plugged in, the drain pump
will run for 20 seconds. The power can be
disconnected and reconnected to verify that
the pump is operating properly.

Water from the ice maker reservoir, or melting
ice from the bin, drains down the bin drain tube

Pump Inlet

Overfill Contact

Full Contacts

Vent Outlet

into the pump inlet, and then into the drain
pump chamber. As the water level rises, it
bridges the “full” contacts, and the pump starts
to run. The pump discharges the water through
the outlet and the check valve. When the “full”
connection is removed, the pump runs for an
additional 12 seconds to empty the tank.

If the water level in the drain pump continues to
rise, due to a slow or blocked drain, or a
blocked vent hose, and touches the “overfill”
contact, power will be turned off to the drain
pump’s 120 VAC outlet, causing the ice maker
to turn off.

RECOMMENDATIONS:

Water softeners or polyphosphate feeders are not cure-alls, but do reduce and, in some cases,
prevent scale buildup. Use only Ice Maker Cleaner (P/N 8171307) if there is scale buildup on
evaporator plate or in water hoses.

CAUTION: Some polyphosphate feeders cause slime buildup. Their use in low mineral content
water should be carefully considered.

NOTE: Reverse Osmosis filters are NOT RECOMMENDED with this unit. These filters can
limit the water flow to the unit and limit its capacity to produce sufficient ice.

A Water Hardness Test Kit (P/N 4171690) is available from FSP

TECH TIPS

CLEANING THE ICE MAKER

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before
operating.

Failure to do so can result in death or
electrical shock.

NOTES:

• KitchenAid recommends cleaning the ice
maker at least once a year. More frequent
cleaning may be required in areas that con­tain heavy amounts of minerals in the water
supply.

• Always wear rubber gloves when handling
cleaning solutions.

CLEANING THE
EVAPORATOR PLATE

NOTE: Use one 16 oz (473 ml) bottle of NU­CALGON
Part Number 8171307. For best performance,
do not use any other type of ice machine
cleaner in the ice maker.

1. Push the OFF keypad to turn the unit off.

2. For easier access to the evaporator, re-

3. Remove the ice from the bin.

4. Unscrew the drain cap from the reservoir



Nickel-Safe Ice Machine Cleaner,

move the cutter grid (see page 4-2).

and allow the reservoir to drain completely,
then reinstall the drain cap.

Reservoir Drain Cap

Continued on the next page.

8-1

5. Read and follow all of the handling infor­mation that was supplied with the ice ma­chine cleaner. IMPORTANT: Do not fol­low the cleaning directions that are printed
on the cleaner bottle. Do not use their
suggested amounts, but use the entire
bottle to clean the unit.

6. Open the bottle and pour a small amount
of cleaning solution onto the cleaning
brush. NOTE: If a brush is not available
you may use a Scotch-Brite pad.

Cleaning Solution
On Pad

7. Using only front-to-back motions, clean
the top of the plate, the sidewalls, and the
front edge of the evaporator. The front-to­back motion is important to prevent
scratches that could keep the ice slab from
sliding off the evaporator plate.

NOTE: More solution may be necessary if
there is a large amount of scale buildup on the
evaporator. The scrubbing process may take
ten minutes or more, depending on the amount
of scale buildup on the plate. The entire plate
should feel smooth when the cleaning is fin­ished.

Scrub Front-To-Back

8. Pour the remaining solution from the bottle
into the water reservoir. Using the empty
bottle, fill the reservoir with clean water to
within 1/4″ of the top of the overflow port.

Add Remaining Cleaner

9. Push the Clean keypad. The Clean light
will turn on to show that the Clean cycle is
in progress. When the light turns off (after
approximately 50 minutes), the cleaning
cycle is complete. During the cleaning
cycle, the system both cleans and rinses
itself.

10. After the cleaning cycle is complete, re­move the drain cap from the water reser­voir, and see if any cleaning solution is left
in the water as it drains out. If the water is
green in color from the cleaning solution,
it will be necessary to run another cleaning
cycle to flush the system. Be sure to re­place the drain cap securely to prevent
leaking.

11. When the flushing process is completed,
press the ON keypad to resume ice pro­duction.

8-2

ADJUSTING THE ICE THICKNESS

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before
operating.

Ice thickness is controlled by the placement of
a jumper at P4 on the control board. The
jumper positions for the three ice thickness
settings are shown below. NOTE: If the jumper
is missing, or in any position other than those
shown below, the unit will produce normal ice
thickness.

Failure to do so can result in death or
electrical shock.

Control board #6100499 with Code Date MGR/
0245 (45th week, 2002), or higher, will allow ice
thickness adjustments. The approximate ice
thickness settings are as follows:

Ice Thickness @ Normal = 0.32″ (8.1 mm)
Ice Thickness @ Thin = 0.28″ (7.0 mm)
Ice Thickness @ Thick = 0.39″ (9.9 mm)
