GETTING STARTED
Introduction to EAH and EC
CMA dishwashers have been used world wide for many years. This manual has been written to help you, the
operator, in your job. Your job is one of the “most important” in this restaurant. Why? Your product, the dishes
and glasses, is the first thing the customer notices when he sits down. Clean, sparkling dishes and silverware will
set the mood for the customer when he observes the table setting.
Receiving and Installation
The dishwasher is shipped from the factory bubble packed on a pallet. The guidelines are listed in a step-by-step
procedure for your reference.
1.
Packaging
Unwrap the machine and check for the following component parts:
Scrap accumulator complete with lid and scrap tray. This is normally an integral part of the
machine
Tube stiffeners. Tube stiffeners must be used to prevent the feed tubes from curling inside the
chemical pail and sucking air. These are pre-installed to the chemical pump and attached to the
back of the dishmachine. The ends of the chemical tubing have been flared so that the tubing will
not pull out of the stiffener. Red is for detergent, white for sanitizer, and blue for rinse aid.
2.
Plumbing
The machine needs the following:
2” pipe for the drain outlet
½” pipe for the incoming water
A flex hose or quick disconnect union. The water inlet is at the top left corner of the dishwasher
3.
Electrical
The machine is 110 volt. The master switch is at the top left side of the control box.
WARNING: Electrical and plumbing connections need to be made by a qualified service person
who will comply with all available Federal, State, and local Health, Electrical, Plumbing Safety
Codes.

4.
Chemical Feeder
The peristaltic pumps are assembled and included within the machine.
5.
Scrap Trap Accumulator
The scrap trap accumulator is designed to perform two basic functions:
It allows a method to discharge all the heavy solids out of the machine with each wash and rinse
cycle.
It provides capacity to drain the contents of one cycle regardless of the ability of the existing drain
to accept the discharge rate.
There is a drain connection sleeve (2”) on the bottom of the scrap accumulator (See drain connection
instruction).
CMA standard dishwashers operate on 110 volts. Other voltage requirements are available on request.
When installing the single rack units, either model EAH or EC, it is recommended that a clean 20 amp
circuit be provided to the machine.
WARNING: Electrical and plumbing connections need to be made by a qualified service person who
will comply with all available Federal, State, and local Health, Electrical, Plumbing Safety Codes.

6.
Water Line
The model EAH & EC should plumbed with ½” hot water line. The time necessary to deliver water to
the machine is controlled by the number four cam. This cam provides the serviceman with the
opportunity to fine-tune the machine to deliver the proper amount with each cycle. Refer to the service
manual for an in depth discussion of this procedure.
7.
Activating Machine
The machine is equipped with a prime switch to activate the peristaltic pump at any time the master
switch is “ON”.
Following the completion of the installation, always fill the machine with water before the machine is
started.
Hold the fill button until the water level is approximately ½” to ¾” below the overflow hole in the
PVC standpipe. This water level should be approximately even with the bottom edge splash guard
in sump area of machine.
Activate the prime switches for the three chemical pumps until the product is discharging into the
sump.
To start the machine, close the doors and the machine will cycle automatically.
The amount of product delivered by each cam is controlled by changing the opening in each cam. When
the micro switch rides down into the cam, the peristaltic pump motor begins to rotate. It will continue to
rotate until it rides up out of the groove. Therefore, to extend the amount of product delivered to the
machine, open the groove. To reduce the amount of product delivered to the machine, close the groove.
Cams are slip fit. A cam adjustment wrench is provided, but the cam can be adjusted with a small
screwdriver or the edge of a table knife.
Technical personnel are available during normal business hours should you, as an installer, have any
questions. We are available to serve you at 800-854-6417.

OPERATION
CMA dishwashers have been used worldwide for many years. This manual has been written to help you, the
operator, in your job.
The manual is divided into three sections. Sections A and B cover start-up and dish handling, and section C
covers troubleshooting.
Starting Instructions
Drain water if it is cold by lifting drain ball until all water is out of the machine.
Check drain screen and clean.
Replace it properly into the sump housing.
Check wash arm spray tips. If clogged, clean with toothpick and rinse at sink.
Check chemical lines to chemical containers
A. Red – detergent line
B. Blue – rinse agent line
C. Clear/White – sanitizer destainer line.
Press fill switch; fill until water is ½” lower than overflow on drain ball shaft or to the bottom of splash
shield.
Hold fill switch in until water level is proper and check temperature (should be approximately 140
degrees Fahrenheit; 60 degrees Celsius).
Insert tray of dishes into machine and close doors. Machine will automatically start when doors are
closed.
After the machine green cycle light turns off, raise doors, remove trays, and allow to dry before stacking.
If the doors are lifted during a wash cycle, the machine will automatically shut off.
The CMA dishmachine will complete the wash and rinse cycle and automatically feed the proper
chemical and turn itself off.

Operating Instructions
1.
Scraping and Pre-rinse
Remove remaining food from utensils. Scrape by hand or by using a cleaning tool such as a sponge or
rubber spatula. For protection of the hands, wear gloves.
Use a pre-rinse hose for wet scraping to remove small particles of soil not removed by the hand scraping
operation. The purpose is to keep excessive garbage from going into the dishwashing machine.
HAND SCRAPING
WET SCRAPING
DON’T PILE DISHES!!
For flatware, it is recommended that they be pre-soaked in a deep pan, generally a bus pan, using a
presoak detergent. This will prevent drying or adhering of soil on flatware and reduce tarnishing. A
presoak detergent is especially useful for the removal of protein soil such as egg, syrup, etc. Allot
approximately 30 minutes for presoaking if possible for better results.
2.
Sorting and Racking
Properly placing the utensils in the rack is one of the most important jobs the operator must perform.
Sort out different utensils, separating dishes, bowls, cups, glassware and flatware.
3.
Racking dishes
PROPER RACKING
Note in the illustration that the
plates are racked without
overlapping and that the sprays
from the top spray arm will strike
the food contact surfaces of the
dishes (face of the dishes)
Rack all the same sized plates together row by row. The dish rack will hold them just right for proper
washing. The entire surface of the soiled dish must be covered by the spray arm to provide sufficient
scrubbing action when the detergent solution is being sprayed on that dish.
Stacking dishes will not save time because the dishes will not be cleaned during the wash cycle and will
require sorting and rewashing.

Rev 1.02

EAH / EC Dishwasher
Racking glasses
Glasses, cups, bowls and other deep dishes must be racked faced down. This is so as not to carry out
wash water and so the sprays can work on the internal surfaces. Rack glasses and cups in a properly
sized compartmentalized glass rack. Allow to air dry.
GLASS RACKING
CUP RACKING
Glasses should be placed in the racks upside down in each compartment. The rinse additive is injected
into the rinse water to prevent spotting and speed the drying process. (Note: A CMA representative can
help you select the proper glass rack for your glasses.
5.
Racking flatware
After presoaking, flatware is placed in a wash basket with handles down to prevent them from “nesting”
which provides maximum exposure to the wash process.

SORTING AND STORING FLATWARE
Stacking and storage of dishes being washed and sanitized is very important. A dish may be perfectly
washed but be completely contaminated from the handling after washing. Avoid storing dishes where
they may be soiled. Handling dishes with the hand on the food contact surfaces should be reduced to a
minimum (towel drying is an incorrect procedure). Do not stack plates and dishes higher than 12 inches.
Their combined weight can destroy the porcelain surface on the bottom plates.

Cleaning and Maintenance
Certain times of the day should be allotted to cleaning the CMA dishwashing machine. Follow the cleaning and
inspection procedures listed below:
1. Cleaning the drain screen
Remove the drain screen and thoroughly clean all foreign material from screen as shown in the illustration.
DO NOT BANG THE SCREEN ON THE TABLE TO JAR FOOD LOOSE. Use the faucet or the pre-rinse
hose. Re-install drain screen and ensure that it is in the proper position.
REMOVE SCREEN
2.
CLEAN SCREEN
Cleaning the washer arms
REMOVE WASH ARM
CLEAN WASH ARM
RE-INSTALL WASH ARM
Inspect the upper and lower spray arms to ensure they are not clogged with food scraps. Otherwise, full
and uniform spray pressures will not be delivered to the soiled dishes.
If there is any question as to the spray arms being clear of food scraps, the spray arms should be
removed and cleaned. Note that water will blow from all jets if they are open. Use toothpick to open
clogged jets and flush to ensure that food scraps are out of the arm. If necessary, the stainless plug in the
end of the arm can be unscrewed and removed to clean the inside of the arm tube at the sink.
After the arm has been thoroughly cleaned, re-install back into the base.

3.
Check Operations
Operate the machine for one cycle. Watch detergent, sanitizer and rinse additive “delivery tubes” at the
point where they inject chemical into the machine. Remember: red tube – detergent; blue tube-rinse; and
clear white tube-sanitizer. Check temperature at the end of the cycle for 120° F minimum.
4.
Cleanup
Wipe down the machine and check the chemical level in the containers. Also inspect machine
for leaks or other items that might cause trouble during a rush period. You are now ready to wash
dishes.
Remember: The chemical containers should be saved for pickup by the serviceman during his regular
call. Do not throw them in the trash bin.
5.
Empty the Scrap Tray
Remove scrap tray drawer and thoroughly rinse out. Clean tray after each meal, or once every hour if
very busy.

Troubleshooting the EAH & EC
Will Not Start
1. Check master switch on the control box to make sure that it is “ON”.
2.
Check circuit breaker that services the dishwasher. Make sure it is “ON”.
3. After (ONLY after) checking steps 1 and 2, call the CMA service technicians.
Out of Chemical
Check backup supply of chemicals. REMEMBER! Red product label to red tube, blue product label to blue
tube, and clear/white product label to clear/white tube. Note that sometimes extra product is left in storage
area at the direction of the restaurant manager. Before calling the CMA service technicians, check with the
manager for backup supplies.
Dishes/Glasses are Not Clean
1.
Before you call the CMA service technician, check your temperature gauge on the machine. Check to
insure water temperature is at least 120° F. The CMA dishwasher must have hot water delivered from
the primary heater at 120° to 140° F. If temperature is okay, then…
2.
Check that your water softener contains salt and is operating properly. Your service agreement from
CMA calls for hot/soft water.
3.
Check that dishes are racked properly. Check the screen and wash arm tips. If they are clear, call the
CMA service technicians.
Machine Will Not Hold Water
Check the drain actuator for a knife, spoon, fork or foreign material then remove.
Water Running on the Floor
If water is overflowing, the scrap accumulator or the scrap drawer may need to be cleaned. If not, call your
plumber- the drain may be clogged.
Water Will Not Drain From the Machine
Check the drain solenoid. Call the CMA service technician.
Water Coming Out of the Door
End plugs may be missing or lose. Check inside the scrap accumulator drawer. If the end plug came off
during operation, it will be inside the scrap trap tray. Simply replace. If end plug is lost, call your CMA
service technician.
Machine Will Not Shut Off
You can turn off the machine in an emergency by turning off the master switch located on the back of the
control box. After turning off the master switch, call the CMA service technician.
