•The dishwasher may only be used once the operating instructions have been
read and understood. Receive instruction in the operation and functioning
personally from the Winterhalter custommer service.
•Only operate the dishwasher in the manner described in this manual.
•In the event of danger or faults, switch the dishwasher off immediately.
•Do not open any machine casings or machine parts if tools are necessary to do
so.
•Work on the electrical equipment is only to be carried out by specilist
personnel.
First diconnect the dishwasher from the mains.
•The water in the dishwasher is not drinking water.
•In the event of faults which are not due to the customer’s water or electricity
supply, contact the Winterhalter customers service.
•In the event of faults with unknown causes, do not swith the dishwasher on a-
gain until the cause is known. If necessary, contact the Winterhalter customer
service.
•Only use detergent and rinse additive which are suitable for industrial dish-
washers. We recommend the products developed by Winterhalter Gastronom.
These are specially suited to Winterhalter Gastronom dishwashers. All quanti-
ties given refer to Winterhalter Gastronom products. Observe danger instruc-
tions printed on packaging.
•During daily cleaning, make sure that no rusting foreign bodies remain inside
the dishwasher. This can cause the interior to rust. The rust particles may
come from non-stainless items to be washed, cleaning aids, damaged wire
trays or baskets or from supply lines which have not been rust proofed.
•Leave the hood open until the next time you put the machine into operation, so
that the inside of the machine can dry out. This is important for long-lasting
protection against corrosion, even with high grade stainless steel.
•Protect the dishwasher against frost. Systems carrying water can be damaged
if they freeze.
•Do not use normal washing-up liquid. This leads to large amounts of foam
building up in the dishwasher.

After it is switched on, the dishwasher heats up the boiler. During this heating up phase, the tank is
filled in batches with water and simultaneously heated up. The temperature indicator lamp lights up
after filling of the tank is completed until the pre-set target temperature is reached. Then the indicator
lamp goes out. It lights up repeatedly during the heating phases of the tank.
Once the tank has been filled completely, a wash cycle is started automatically to signal readiness for
operation.
The dishwasher is fitted with an automatic hood start. When closing the hood, slight pressure has to
be applied to overcome the hood catch position. The pre-set programme starts as soon as the lid has
been closed.
The container for rinse additive is installed separately from the dishwasher. Dosage for the rinse addi-
tive is controlled automatically by the dishwasher.
