washing items and utensils from the catering industry and related trades (butcher shops, bakeries). Any
change in design or use of the utensil washer carried out without the written permission of Winterhalter
Gastronom GmbH leads to the guarantee and product liability becoming null and void. If damage is
caused to the utensil washer due to failure to observe the instructions given in this manual, no claims
under guarantee can be made to Winterhalter Gastronom GmbH.
Installation and commissioning
Installation of the utensil washer and connection to the customer’s water inlet, waste water drainage and
electricity connections are to be carried out in accordance with national and local criteria by qualified en-
gineers in accordance with the “Installation instructions for Winterhalter Gastronom utensil washer“.
Main fuses and main switch to be provided by customer.
After proper connection to the customer’s water and electricity connections, contact the Winterhalter
works representative for your area.
Commissioning (so-called washing in) and instruction in operating the utensil washer is to be carried out
by the Winterhalter customer service. For this purpose, use the „Commissioning regulation for Winterhal-
ter Gastronom dishwashers GS 502/GS 515/GS 640/GS 650/GS 660“.

•The utensil washer only may be used after the operating instructions have been
read and understood. Ensure that the operator has received instruction in the op-
eration and functions from a Winterhalter customer service representative.
•Only operate the utensil washer in the manner described in these operating in-
structions.
•In the event of danger or faults, switch the dishwasher off immediately. Switch off
customer’s main switch. Only then is the utensil washer safe.
•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 specialist personnel.
First disconnect the utensil washer from the mains.
•The water in the utensil washer is not drinking water. Do not use it to prepare food
or drink it.
•In the event of faults which are not due to the customer’s water or electricity sup-
ply, contact the Winterhalter customer service department.
•In the event of a fault of which the cause is unknown, do not switch the utensil
washer on again until the cause has been established. If necessary, contact the
Winterhalter customer service department.
•Only use detergent and rinse additive which are suitable for industrial utensil
washers.
We recommend the products developed by Winterhalter Gastronom. These are
specially developed to suit Winterhalter Gastronom utensil washers. All quantities
given refer to Winterhalter Gastronom products. Observe danger instructions
printed on packaging.
•During daily cleaning, make sure that no rusting foreign bodies remain inside the
utensil washer. This can cause the interior to rust. The rust particles may come
from washed non-stainless items, cleaning aids, damaged wire baskets or from
supply lines which have not been rust proofed.
•Leave the door 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 utensil washer 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 utensil washer.

•Check the customer’s required FI-residual current operated device for faults regu-
larly according to the regulations by pressing the test button.
•In addition to daily cleaning, we recommend that you have the utensil washer
serviced at least twice a year by a Winterhalter customer service engineer.

After the machine is switched on, the boiler and tank are filled and heated up to operating temperature.
The programme button (6) is lit red during the heating up phase.
As soon as the pre-set target temperatures (tank: approx. 60°C, boiler : approx. 85°C) have been
reached, the machine is ready for operation. The programme button (6) is now lit green.
The machine is operated with fully automatic programmes consisting of the program steps
washing, dripping off and rinsing.
The rinse additive is dosed by a built-in dosing device. With GS 660, the container for the rinse additive
can be stored inside of the machine. With the other machines it is stored separately.
Detergent must be added by hand (in the form of powder) or by means of a built-in or external dosing
pump (in the case of liquid detergent), depending on the equipment of the machine. With GS 660 the
container for the detergent can be stored inside of the machine. With the other machines, it is stored
separately.
:DVKLQJThe circulating pump conveys the wash water out of the tank via the wash arms and nozzles
onto the wash items. The wash arms move thereby side to side, thus guaranteeing powerful and efficient
cleaning of the wash items. During circulation the wash water is continuously circulated through a filtering
system and the patented Mediamat Cyclo (floating particle separator).
'ULSSLQJRII There is a short pause after washing to allow the wash water to drip off the washing items.
5LQVLQJ During the last programme step, the cleaned items are rinsed with fresh, hot water to remove
residual water and to warm up the wash items for optimum drying outside of the machine. In addition, the
rinse water refreshes the wash water.

If changing to a different GHWHUJHQWW\SH (even one by the same manufacturer), the suction and pressure
hoses must be rinsed with fresh water before connecting the new detergent container.
Otherwise, the mixing of different types of detergent will cause crystallisation, which may result in a
breakdown of the dosing pump.
Failure to observe this rule will lead to the loss of guarantee and product liability claims vis-à-vis Winter-
halter Gastronom GmbH.

•Remove the suction stick from the empty detergent container and place it in a container filled with
fresh water.
•Trigger several wash programmes until fresh water is visibly pumped into the machine over the dos-
age pump. The suction and pressure hoses are rinsed thereby.
•Insert the suction stick in the new detergent container. Operate the machine as usual.

Before the washing items are loaded into the machine, they should be scraped clean of the largest lefto-
vers and scraps: pour off leftover gravy, soak dried on leftovers. Do not use steel sponges to do this, be-
cause the machine could be contaminated with rust thereby.
Wash items such as buckets, pots, cauldrons, ham roasting dishes etc. must be
placed into the utensil rack with the opening facing downwards.
The empty intermediate spaces can be filled with small utensils such as ladles etc.
The wash items should however not be laid on top of each other because spray
shadows may be created and thus possibly affect the washing result.
When washing baking sheets, put these into the insert with forward slant. Ensure
that the soiled sides face downwards.
Use the plastic small parts basket to wash cutlery and other small parts. After it is
filled it is mounted on the utensil basket. Sort knives and other sharp objects into
the upright cutlery basket with the handles facing upward. Long, sharp utensils
must be laid in the wash basket or be washed by hand.
Light parts made of e.g. plastic can easily slip or turn over during washing. Put a
plastic basket on these light parts if necessary.
