2. Safety instructions
2.1 General information
The machine is CE marked, which means that it complies with the requirements
of the EU machinery directive with regard to product safety. Product safety means
that the design of the machine will prevent personal injury or damage to property.
Modifying the equipment without the approval of the manufacturer will invalidate
the manufacturer’s product liability.
To further improve safety during installation, operation and servicing, the operator
and the personnel responsible for installing and servicing the machine should
read the safety instructions carefully.
WD-90 DUO Rev. 1 (201702)
Switch off the dishwasher immediately in the event of a fault or malfunction. The
machine must only be repaired by trained engineers. The regular checks described in the installation and user manual must be carried out in accordance with
the instructions. The machine must be serviced by personnel authorised for this
purpose by the manufacturer. Use original spare parts. Contact an authorised
service company to draw up a programme of preventative care and maintenance.
Hazardous situations may arise if the instructions above are not followed.
Before the machine enters service, ensure that the staff are given the necessary
training in handling and looking after the machine.
2.2 Transport
Handle the machine with care during unloading and transport; there is a risk of it
tipping over.
2.3 Installation
This symbol on a machine component warns of the presence of electrical voltage.
The component may only be disconnected by a qualified electrician. Make sure
the machine is non-live (turn off the power at the safety switch) before any work
is performed on the machine. The electronics in the machine is sensitive to electrostatic discharge (ESD), which is why a static electricity wristband must be used
when handling the electronics.
The dishwasher’s electrical cabinet is located within the cover plate on the righthand side of the dishwasher. The cover plate creates a seal against the electrical

2.5.5 Sounds
2.6 Cleaning
WD-90 DUO Rev. 1 (201702)
During washing using the potwash programmes with granules, the sound level
can become high (see
Sound levels table in chapter entitled Technical data in In-
stallation and User Manual). Hearing protection should therefore be used when
running potwash programmes with granules.
The temperature of the water in the tank is approximately 55–65°C, and the water
contains detergent. Be careful when draining and cleaning the tank. Use protective gloves.
Pressure washers must not be used for cleaning the machine. If water from a
pressure washer is directed at the electrical cabinet, it may penetrate the cabinet
and damage the electrical equipment, thereby impacting on safety.
To meet current regulations, electrical components of approved enclosure class
are used. No enclosure class is designed to withstand high pressure.
The machine exterior may not be washed down with a pressure washer, nor
should the machine be washed down using a hose pipe (applies mainly to connection points). Water may penetrate the electrical cabinet and control panel and
damage the equipment, thereby impacting on safety.
If floors are cleaned using high-pressure equipment, water may splash up under
the machine and damage the components. These have not been designed to
withstand being washed with water at high pressures. Never use a pressure
washer to clean the floor within one metre of the machine without the special protective covers that are available to prevent splashing. Problems with splashing
can also occur when using an ordinary hose pipe.
2.7 Repairing and servicing the dishwasher
Make sure the machine is non-live before opening the electrical cabinet. Turn off
the power at the mains switch. Avoid touching hot pipes and the booster heater.
2.7.1 Directions in the event that the machine does not work or breaks down
If the machine breaks down, e.g. a pipe breaks or the tank leaks, etc., turn off the
power at the safety switch. Call a service engineer.
If the machine has to be stopped while washing is in progress, e.g. because you
selected the wrong programme, something happened with the basket or the items
being washed when washing was under way, etc., press the dishwasher’s On/Off
button. If you need to open the hood, the dishwasher must be re-started (see
“Cancelling a wash program and stopping the machine” on page 41).

3.9 Recycling
Comply with local regulations governing recycling of packaging, protective plastic
laminates, granules, etc., and recycling when the machine is destroyed at the end
of its useful life.
The packaging consists of wood, corrugated cardboard and plastic and must be
recycled as these fractions or as combustible material.
Protective plastic laminates and granules are to be sorted as plastics or combustible material.
The machine is manufactured from stainless steel plate, but includes a certain
amount of brass. It also contains electronic components. These should be recycled in accordance with local regulations.
3.10 Technical documentation
It is important that the members of staff who are to use the machine read and understand the installation and user manual which comes with the dishwasher. Alternatively, the safety officer of the premises at which the machine is to be used
can train the staff in the safe use, handling and operation of the dishwasher. The
machine has to be handled correctly if it is to be used in a safe manner. Keep the
installation and user manual near the machine where it will be easily accessible
to users. If the installation and user manual is lost or destroyed, a new one must
be ordered from the dishwasher manufacturer or its local representative.

4.1.2 Before filling the dishwasher with water
Before filling the machine with water prior to the day’s work shift, or after a change
of water, a check should be performed to verify the following:
• The machine has been properly cleaned (See “Cleaning the inside of the
machine” on page 48.).
— The strainers have been cleaned.
— The wash arms are not dirty or clogged.
— The water tank has been rinsed out.
— The level sensors in the tank are not dirty.
• Water taps on the water pipe to the machine are open.
• Granules are only in that part of the tank intended for them.

The granules are filled in that part of the tank that is located under the filter
nearest the front of the dishwasher, see diagram. If all cover plates and
filters are sitting in place, the granules should automatically end up in the
right part of the tank.
• There is detergent and drying agent in the relevant dispensers.
• The level pipe (1) is clean and has been correctly fitted, i.e. the rubber
sleeve (3) on the level pipe achieves a good seal with the bottom of the
tank, and the foam separator (2) is clean and not jammed in position.
• Cover plates and strainers are correctly fitted.
• The dividing wall in the tank has been cleaned.

4.1.3 Before washing with a potwash program
When washing with a potwash program, you should remember the following:
• Make sure as much food residue as possible is removed from the items to
be washed before putting them in the machine (this will help reduce the
number of times the washing water in the machine will need changing).
• Make sure nothing projects from the washing basket which might catch the
walls of the dishwasher and prevent the basket from rotating.
• Check that the correct wash program has been selected.
4.1.4 Before washing with a normal wash program
To obtain the best wash result when washing with a normal wash program, you
should remember the following:
• Make sure as much food residue as possible is removed from the items to
be washed before putting them in the machine (this will help reduce the
number of times the washing water in the machine will need changing).
• Do not allow food residues to dry on the items to be washed using the
normal wash program. If, for instance, the items to be washed have to
stand overnight without being washed, as much of the food residue as
possible must be removed and the items left to soak. Use a soaking agent
and follow the supplier’s instructions.
• Check that the correct wash program has been selected.
4.1.5 Positioning of items in baskets
Potwash
Potwash items are positioned in the baskets supplied. The dirty side (the inside)
of the items to be washed must face away from the centre of the basket. Items
must be positioned so that water will not collect in them, e.g. canteens, pots and
pans, etc., positioned on the bottom of the basket must be turned to face bottom
up.
Gastronorm containers
Gastronorm containers in sizes GN1/1, GN1/2, GN1/3, GN2/3 and GN2/8 can be
washed in the basket without any problem. For other sizes, special accessories
may be needed. Contact your dealer.

4.2 Washing
4.2.1 Filling with water
Before washing can be started, the dishwasher tank must be filled with water and
the detergent mixed. The points below must be followed when the dishwasher
has no water in it.
When filling the machine with water, you should not have any items in the machine. Water which is hotter than for normal washing is flushed into the washing
compartment when the machine is being filled. This can result in food residue getting burnt onto any items in the machine, giving a poorer wash result.
This is what you should do:
1. Carry out the recommended checks
before washing commences, see “Before filling the dishwasher with water”
on page 30.
Start the machine

4.3 After use
4.3.1 Care and maintenance
To obtain a good wash result when washing and to get the best possible benefit
from the dishwasher, it needs to be looked after and maintained at given intervals.
Much of the care and maintenance can be performed by the dishwashing room
staff, while other maintenance will require trained service personnel to perform
the work.
The table below shows the recommended intervals for various maintenance activities. The recommended intervals below should be seen as the minimum
amount of maintenance under normal use of the dishwasher. Maintenance may
be performed more frequently, depending on how often and how much you wash,
and the type of items you wash, etc. It is important to have an eye to the conditions
which actually obtain on-site.

Using the dishwasher
Scraping – It is important that as much food residue as possible is scraped off
the items before putting them in the machine. Proper scraping will mean the water
in the washer tank will not need changing as often.
Detergent and drying agent dosage – The dosage of the detergent and drying
agent will affect the wash result. If too high or too low a dosage is suspected, the
detergent supplier should be contacted. There is the option of fitting a sensor in
the tank to measure detergent concentration in the water. Using this, detergent
can be added automatically to achieve the right dosage. Contact your detergent
supplier!
Water change – The water in the tank should be changed at least once a day dur-
ing normal use of the dishwasher. In certain cases, e.g. if many or highly soiled
items are washed, it may be necessary to change it more often.
Water turnover – If water turnover in the machine is not good enough, this can
lead to problems such as starch spots on glass and on the undersides of plates.
Contact the service company for help in dealing with the problem.
Temperature – If the temperature during washing and the final rinse is too low,
the items in the wash will not emerge clean. If you suspect this is the case, contact
the service company.
If normal wash items are rinsed (pre-rinsed) before being put in the dishwasher,
the temperature of the water must not be too high (<40
a risk that proteins and starch will burn onto the items, and you will end up
with a poor wash result.
WD-90 DUO Rev. 1 (201702)
°C). Otherwise there is
Program selection – The time taken by the wash and final rinse, as well as the
volume of water used for the final rinse are all important for the wash result. If the
items are not cleaned, you should try selecting a program with a longer wash cycle, see “Technical data” on page 63. The volume of water used for the final rinse
of the washed items can be adjusted by a service engineer – contact the service
company.
Water hardness – If the water used for washing is hard (>10°dH), a higher con-
centration of detergent may be needed to ensure the washed items emerge
clean. Contact your detergent supplier.
Cleaning, rinse pipes – Cleaning of the machine is important for achieving a
good wash result. See “Care and maintenance” on page 42 for recommendations
as to how often cleaning should be performed. In certain cases it may be necessary to clean more frequently than recommended.
Stacking of items – The positioning of items in the basket is critical for how the
washing water will manage to rinse them during washing. This in turn will determine the wash result, see “Positioning of items in baskets” on page 32.
Soaking – (does not apply to potwash programs with granules, where soaking
should not be used) – In certain cases the items need to be soaked before
washing, if they are to emerge fully clean. In such cases the items are soaked e.g.
overnight in water with a soaking agent. Follow the instructions of the detergent
supplier.
Ordinary washing-up liquid must
causes foam to form and produces poor wash results.
NOT be used in the machine or for soaking. It

4.3.3 Changing the water
Take care to scrape off food residues from the items before putting them in the
dishwasher. If residues are properly scraped off, the water will not need changing
as often, saving time, money and the environment.
The water in the washer tank should be changed daily. More frequent changes of
water are needed if:
• Significant amounts of foam build up in the machine; e.g. if you can see
foam coming out of the waste pipe, or the strainer in the machine’s tank is
covered with foam. If this occurs, the water should be changed
immediately.
• A lot of items are washed at certain periods of the day. Schedule water
changes so that a good wash result is achieved over the entire work shift.
Change the water, for instance, after periods when a lot of items have been
washed.
• On checking the wash result you discover any of the problems mentioned
in the chapter “Check the wash result” on page 44 above.

4.3.4 Cleaning the inside of the machine
The machine should be cleaned at least once a day when in normal operation.
Once a week, more thorough cleaning of the machine should be carried out,
where the rinse pipes and granules are also properly cleaned and a check performed on the amount of granules.
Make sure you adhere to the following when cleaning the machine:
• Do NOT use steel wool as this can cause rust to form on the machine.
• Pressure washers can damage the machine and must NOT be used for
cleaning purposes. Never use a pressure washer to clean the floor within
one metre of the machine without the protective covers that are available
to prevent splashing. The supplier cannot be held liable for any faults
caused by the use of pressure washers on the machine and any such use
will invalidate the warranty.
This is what you should do:
1. Open the hood – press the button for operating the hood (the button at the
very bottom of the panel).
2. Remove the rotating table from the machine. Get hold of the spokes in the
rotating table, towards the hub, and pull it straight up towards you. Where

WD-90 DUO Rev. 1 (201702)
4.3.7 Checking the amount and cleaning the granules
For normal operation, the granules should be cleaned and their amount checked
at least once a week.
Collection of granules
1. Open the machine hood. Press the button at the very bottom of the panel.
2. Remove the rotating table by getting hold of the spokes, towards the hub,
and pull it straight up towards you.
3. Replace the strainer next to the granule collection basket and the cover
plate with a hole for the basket.
4. Run the granule collection program
5. Once the granule collection program has completed its cycle and the hood
has opened, remove the basket from the machine.

7. Once this is done, pour the granules back into the machine, into that part
of the tank which is nearest the front of the machine.
53
Using the dishwasher
25-4-03-004_1
Cleaning
1. Pour the granules into a bucket.
2. Place the bucket in a sink.
3. Rinse the granules with water. Stir the granules round at the same time.
4. Remove any food residues and detritus.
Checking the granules
Once a week you should check there are enough granules in the machine.
The amount of granules is checked by:
— measuring them with a litre measure or similar (for granule volume, see
— the amount of granules is checked when the granules are in the granule
WD-90 DUO Rev. 1 (201702)
“Technical data” on page 63), or
collection basket. There is a measuring stick in the basket that indicates the
height the granule level should reach.If the granules reach this level, the
amount is correct.
Add fresh granules as needed!
4.3.8 Changing the granules
The granules should be changed once or twice a year. It may be a good idea to
do this during longer scheduled periods without use, such as e.g. holiday periods
or similar.
Collect the old granules in the machine as instructed in “Checking the amount and
cleaning the granules” on page 53.
Different makes of granules differ in both size and weight. The machine is
designed to use Wexiödisk original granules, and these should be used when
filling with new granules. The amount to be added to the machine is indicated
under “Technical data” on page 63.
Recycling the granules
Used granules can be recycled either as hard plastics or combustible materials.
