possible before washing. This also means that the water in the
machine does not need to be changed as often. Scrape better.
•Detergent and drying agent dosage: When using liquid detergent and desiccant, the same make and black should be
used. The dosing affects both detergent and drying results of
the items. The hardness level of the water affects the consumption of detergent.Contact the detergent supplier
•Temperatures: At incorrect temperatures the dishes will not
be clean. Contact a service technician if you need to change
the set values.
•Programme selection: Programme with too short a washing
time selected. Choose a programme with a longer washing
time.
•Cleaning the machine: Insufficient cleaning of the machine
affects the results of the washing. Ensure better cleaning of
the machine.
•Placing items in baskets: Incorrectly placed items can mean
that the washing water does not reach the items during washing and rinsing.
•Soaking: Items with hard dried food. Soak the dishes in water.
Do NOT use washing-up liquid.
4.2.5Stopping the machine during operation
If the machine needs to be stopped during operation for some reason, press but-
n (14) for an emergency stop.
to
Before the machine can be restarted, the emergency stop button (14) must be reset by turning it in the direction of the arrows. The alarm is reset by pressing button (7) and the doors open. The problem which caused the emergency stop must

4.2.6Changing the water
To achieve the best possible washing results, it is important that the water is
changed frequently.
NOTE: The water in the wash tank must be changed regularly, otherwise foam
will start to form and the washing results will deteriorate. If the filters are clogged
with foam or if foam comes out of the waste pipe, the water must be changed immediately.
The machine has an alarm which indicates when the water is dirty and must be
changed. The alarm is set off after a preset number of wash cycles. LED (4) flashes to indicate that the alarm has been activated. The alarm can be reset by pressing button (7). The machine can also be locked to prevent it from being used any
further when the water change alarm is triggered. The setting must be changed
by a service engineer in the machine's software.

4.3After use – cleaning
Numbers in brackets refer to the diagram in the chapter "The machine’s design".
HACCP is a preventive inspection system to ensure hygiene requirements are
met during the washing process and cleaning of the machine. As a result of its
design, the machine meets strict hygiene requirements. Regular, thorough cleaning is also important from a hygiene perspective. A machine that is properly
cleaned helps produce a good wash result, reduces the risk of dirt accumulating,
increases the service life of the machine and reduces the risk of emergency shutdown.
If the machine will not be used for a longer period, the power to the machine
should be turned off using the power switch, the water supply turned off and doors
should be left open.
See the WEB Tool manual for the HACCP.

caused by the use of pressure washers on the machine and any such use
may invalidate the warranty. There is a risk of splashing even if the floor is
hosed down.
WD-18CW Rev. 3,0 (201802)
Steel wool and pressure washers must not be used for cleaning.
4.3.6Periodic servicing
ng intervals between using the machine
Lo
If the machine is not being used for a long period, the machine should be disinfected with chlorine.
If the machine is not being used for a long period, cooking oil should be sprayed
into the pump housings. The oil will prevent rust from forming in the pump housing
and jamming the impeller. The cooking oil is sprayed into the pumps' inlet pipes.
(This should be done by an authorised engineer.)
