25/09/2018 Washtech CDe120 Operator Manual 5
Machine Positioning
•Unpack machine, check for damage and complete delivery.
•Install machine on sound waterproof self-draining floor and use adjustable feet to level
machine.
NOTE: Failure to level the machine correctly may result in leaking during the cycle,
overflowing from the door sill, poor hygiene through the wash tank not being able to
drain correctly, and/or visibly uneven door.
•Allow room for detergent to one side of machine or in adjacent cupboard. 20 litre container
requires approximately 450H x 250W x 350D, but smaller containers are available from many
suppliers.
Inlet Water Operation - Cold
Incoming water should be within the following standard requirements:
•Temperature: 20°C.
•Connection: 20 mm (3/4” BSP) male
NOTE: Flush supply line before connection. Poor quality supply or excessive water
hardness may affect performance or damage machine – filtration and/or softening is
recommended.
•Flow rate: minimum 20 litres per minute
•Pressure: between 200 and 350 KPa
NOTE: This machine is not equipped with a rinse booster pump as standard and relies on
incoming water pressure to drive the rinse cycle.
NOTE: Above this range fit pressure limiter. Below this range fit a rinse booster pump. Do
not use small diameter plastic supply lines
•Backflow prevention: Watermark approved Atmospheric Vacuum Breaker (AVB) fitted
standard. Watermark Certification #08603
Inlet Water Fill - Hot
Incoming water should be within the following standard requirements:
•Temperature: 65°C.
NOTE: Excessively high temperatures may damage the solenoid which can result in
flooding should this component fail. High temperature solenoids are available and can be
retrofitted if necessary.
•Connection: 20 mm (3/4” BSP) male
NOTE: Flush supply line before connection. Poor quality supply or excessive water
hardness may affect performance or damage machine – filtration and/or softening is
recommended.
•Flow rate: minimum 20 litres per minute
•Pressure: between 200 and 350 KPa
NOTE: Above this range fit an approved pressure limiter. Below this range fit a rinse
booster pump. Do not use small diameter plastic supply lines
•Backflow prevention: Watermark approved Atmospheric Vacuum Breaker (AVB) fitted
standard. Watermark Certification #08603
Installation Instructions
25/09/2018 Washtech CDe120 Operator Manual 6
Water Quality Requirements
The incoming water should also be within the following parameters:
Hardness ppm pH
min 20 7
max 100 8
Ions Cl- SO4Fe Mn Cu Cl2
Max mg/L 100 400 0.1 0.5 0.05 0.1
NOTE: Levels above or below the stated requirements can be expected to increase
component wear and reduce the expected useful life of the dishwasher. If in doubt, it is
best to consult a water specialist and have the incoming water professionally tested and
treated if necessary.
Power
•Electrical supply required is 3p/35A 415V 50Hz via switched outlet adjacent to machine.
NOTE: Equipment contains dangerous voltages and can be hazardous if installed or
operated incorrectly. Non –compliance with warnings or failure to follow the
instructions contained in this manual can result in loss of life, severe personal injury or
serious damage to property.
Chemical
•Detergent and rinse aid pumps are not supplied with the CDe120. We recommend you
consult your chemical supplier and/or a local chemical expert for their recommended
detergent and Rinse Fluid injector pumps.
NOTE: Commercial detergents can be hazardous – read instructions, store safely and
handle with care. Care needs to be taken when changing chemicals, ensuring that the
detergent is not accidentally connected to the rinse fluid inlet line.
NOTE: If uncertain, please consult a chemical specialist for assistance in selecting the
right chemicals and calibrating machine settings to suit this along with your unique site
conditions and requirements.
Waste
•50mm connection required to point B as specified on install diagram. An S-trap must be fitted
on each of these points.
NOTE: Either copper or P.V.C. may be used for the waste connection – P.V.C. is more
resistant to some harsh detergents. Some authorities however suggest that copper is
required because the machine rinses at up to 90°C. It is important to note that rinse
water mixes with the 65°C wash water before discharge and then flows into the sink
trap where the water is further cooled before entering the drainage plumbing. We
recommend consulting your local authority to ensure your site remains compliant.

•Complete attached Installation Checklist to ensure machine is installed and running correctly,
and operator is familiar with operating procedures.

Installation Troubleshooting
Machine not starting or filling
•Ensure water supply to machine is turned on.
•Ensure power supply to machine is turned on.
•Check that the water inlet hose isn’t twisted or kinked.
Poor wash results
•Check that there are adequate pre-rinse processes in place.
•Ensure high quality non-foaming commercial dishwasher detergent has been connected at
the correct dosage for your site, water quality and application. If uncertain, consult a
chemical specialist.
•Ensure that the wash temperature is between 60°C and 65°C.
Chemical residue on items after the cycle
•Check water pressure, this is likely too low and below the minimum 200kPa required.
•Check that nothing is obstructing the wash & rinse arms.
•Check the rinse fluid dosage is not too high. If uncertain, please consult a chemical specialist.
Dishwasher is foaming
•Ensure high quality non-foaming commercial dishwasher detergent has been connected at
the correct dosage for your site and application. If uncertain, please consult a chemical
specialist.
•#NNQYYCUJYCVGTVQJGCVVQCVNGCUVĹ%RTKQTVQUVCTVKPIVJGHKTUVE[ENGCUUQOGEQOOGTEKCN
dishwasher chemical will foam at low temperatures.
•Low water pressure can result in above average detergent concentrations. As low water
pressure also impacts rinse results, we recommended this is solved by installing a rinse pump
rather than compensating by reducing chemical dosages.
Other equipment in the kitchen has needed filters or has scale
•Due to the high temperatures in dishwashers, scale will build up in the wash tank, on the arms
and in the rinse tank. The incoming water should be treated. If uncertain, please consult a
water specialist.
Other equipment in the kitchen has needed an RO water filter
•As with the Combi-Oven, high chloride levels will do irreversible damage to a number of the
components inside a commercial dishwasher. The incoming water should be appropriately
treated. If uncertain, please consult a water specialist.
Pawl drive not operating
•Clear the area around the limit switch on the roller table.
•Adjust the clutch tension of the Pawl Drive motor, the Pawl drive clutch tension can be
tightened by turning the 2 nuts at the bottom of the pawl drive shaft clockwise or loosened
by turning the 2 nuts anticlockwise.
(Note: the tension must be at a level where a person can grab the pawl drive with both hands
and stop the pawl drive motion).
Too much steam escaping the machine
•$[FGHCWNVVJGYCUJVJGTOQUVCVKUUGVVQĹ%TGFWEGVJKUVGORGTCVWTGĹ%KHTGSWKTGF
•Check the hot/cold water solenoids connections are connected to the correct water mains
outlet.
Grinding noise escaping from the machine
•Wash pump rotation must be checked after installation to ensure correct direction (excessive
noise and damage with incorrect direction)
Machine stops and refills during the commissioning stage
•Fit the curtains according to the Operator Care – curtain diagram (page 13).
•Ensure the Scrap Trays are fitted in the Wash and Rinse Zones.

•Part #: CDE120 RL Curtains
•Date: 28/08/2018
•Version: 1-A
Types Of Curtains
1. Long anti splash curtain 600 x 475 (Part number: 840 90011)
2. Medium anti splash curtain 600 x 230 (Part number: 840 90012)
3. Short anti splash curtain 600 x 150 (Part number: 840 90013)
The Purpose of Curtains:
•To keep the heat inside the zones of the machine
•To stop water splashing from one zone to another. This prevents wash and rinse water
mixing. If this happens the water quality will be reduced.
•Curtains must be placed in their correct positions to work properly. They must also be the
correct way around.
•Broken curtains need to be replaced promptly.
Weekly Cleaning
•Remove curtains from hooks
•Place each curtain into a dishrack and wash through the machine
