1. Intended purpose
The Winterhalter Gastronom dishwashers GS 14, GS 14E, GS 15 and GS 15E are designed for
cleaning all types of kitchenware used in catering establishments. They may only be used for this
purpose, and in accordance with the operating instructions.
Any other usage or modification of the machine's design without our written consent will exempt us from
all guarantee and product liability obligations.
2. Installation and initial start-up
The machine must be installed and connected to the on-site supply and waste pipes in accordance
with the "Installation instructions for Winterhalter Gastronom glass and dish washing machines".
The initial start-up (or so-called ”running-in” phase) and the briefing of the machine operator must be
performed by Winterhalter service technicians in accordance with the "Start-up regulations for
Winterhalter Gastronom dish and utensil washing machines". For this purpose, you should contact
the Winterhalter representative responsible for your factory once the machine has been correctly

5. Before the wash
5.1 Preparing the machine for operation
To do this, proceed as follows:
A) Open the on-site shut-off valve of the water
supply pipe.
B) Turn on the on-site main switch.
At the same time, test the on-site residual-
current operated circuit-breaker for your own
safety by pressing the test button.
C) Openthe door. Pull the rack out of the
machine.
D) Insert the standpipe into the wash tank by
twisting it gently until it fits tightly.
E) Check to make sure the surface strainers are
correctly positioned in the tank.
F) Check to make sure all wash arms are in
place.
G) Slide the rack into the machine.
Close the door.
H) Press the power switch (1) (lights up when
pressed).
The tank is now filled automatically.
As soon as the necessary water level is reached
in the tank, the machine is heated to operating
temperature.
The white indicator lamp (2) lights up until the
operating temperature is reached and then goes
out again.
The heating time depends on the temperature of
the incoming water.
I) Check the filling level in the rinse aid
container through the slit in the front panel and
top it up if necessary.
Make sure the rinse aid container never
becomes completely empty.
Additional rinse aid is metered automatically.
We recommend the use of our Winterhalter
Gastronom rinse aid product.
5.2 Detergent pre-dosing
Add an initial dose of approx. 50g detergent
(powder) to the heated tank water.
If using other detergents, follow the dosing
directions printed on the packet.
Remember that more detergent is needed the
dirtier the dishes or the harder the water.
To ensure that the detergent mixes in thoroughly
and does not settle on the floor of the tank, you
should switch on the machine briefly after adding
the initial dose.
Press pushbutton (3).

NOTE
The measuring cup supplied with our detergent
containers holds approx. 200g of powder. One
heaped dessertspoonful of powder is equivalent to
approx. 20g. To avoid staining the tank floor, it is
advisable to dissolve the detergent in hot water
before adding it or to pour it onto the plastic
surface strainers.
NOTE
Only use detergent and rinse aid products
which are suitable for commercial dishwashers.
Observe the safety information printed on the
packaging.
We recommend the use of our Winterhalter
Gastronom detergent.
NOTE
If the machine is equipped with an automatic
detergent dosing device (optional extra), there is
no need to add detergent manually.
See the corresponding instruction manual on how
to use this device.
6. Topping up the regenerating salt
(GS 14E, GS 15E)
In models GS 14E and GS 15E with built-in water
softeners (SoftMatik), the "REG" indicator (7)
lights up when the salt level in the container is low.
In this case, fill the salt container with special
regenerating salt for water softeners.
The salt container must only be filled
with regenerating salt! Any other
chemicals, e.g. detergent or rinse aid,
will inevitably result in damage to the machine.
The salt should be added in fine-grain form (max.
5-7 mm grain size): salt tablets are not suitable.
We recommend the use of our Winterhalter
SoftMatik regenerating salt.
Procedure:
•Unscrew the cap of the salt container.
•Fill the container with one bag (500g) of
Winterhalter Softmatik regerating salt
using the supplied funnel.
•Remove salt remnants from the screw thread
and sealing surface of the salt container.
•Screw the cap of the salt container back on
again and tighten it by hand.
•Activate Programme 1 by pressing key (3).
7. Wash cycle
Arrange the soiled kitchenware correctly in the
rack, then push the rack into the machine and
close the door.
Select the right programme for the relevant degree
of soiling and press the button to start.
For lightly soiled items, you should select the
”Programme 1” button (3). Programme duration:
GS 14 approx. 150s = 24 racks/h
GS 14E approx. 150s = 24 racks/h
GS 15 approx. 75s = 48 racks/h
GS 15E approx. 120s = 30 racks/h
For heavily soiled items, select the ”Programme 2"
button (4). Programme duration:
GS 14 approx. 300s = 12 racks/h
GS 14E approx. 300s = 12 racks/h
GS 15 approx. 150s = 24 racks/h
GS 15E approx. 180s = 20 racks/h
Sequence of operations
•Circulation of detergent solution: intensive
cleaning from above and below.
•Freshwater rinse with water heated to 85°C
(containing rinse aid).

89000825
10/98 sch Winterhalter Gastronom GmbH Postfach 1152
D-88070 Meckenbeuren 5
•The indicator lamp in the selected pushbutton
remains alight throughout the programme
sequence.
•Once the lamp is extinguished, the door can be
opened and the rack can be pulled out of the
machine to allow removal of the washed items.
•Do not remove the rack too early, as this will
interrupt important stages of the programme.
•Reload the rack and continue washing as
described above.
•Make sure the door remains closed when the
machine is not in operation in order to avoid an
unnecessary waste of energy.
The washed items will dry clean and shiny within a
short time due to their own heat and the effect of
the rinse aid added to the rinse water. There is
therefore no need to wipe them with a tea-towel.
Topping up the detergent
The concentration of detergent in the detergent
solution decreases steadily during the washing
process (due to the freshwater rinse).
You should therefore add a further 60g of detergent
powder after approx. 10 wash cycles.
After adding the detergent, start programme 1
immediately to make sure it mixes in thoroughly.
Heavily soiled items...
...can be washed intensively (max. 15
minutes).
For this purpose, press pushbutton (5).
This button lights up during operation. To end the
wash cycle, press pushbutton (5) again. Then
activate Programme 1 by pressing button 3.
NOTE
If the maximum time of 15 minutes is exceeded,
the machine switches to fault mode (see
"Operating faults").
Routine checks
•Check the rinse aid level in the container.
•Check to make sure the washed itemsare
clean.
•Check that the temperature indicator lamp
(2) goes out each time. This means that the
setpoint temperatureshave been reached.
•Check the strainers inside the machine for
dirt and clean them if necessary.
8. After the wash
A) Open the door and take the rack out of the
machine.
B) Remove the standpipe.
This will drain the tank.
C) Close the door after draining the tank.
D) Clean the inside of the drained tank by
pressing the pushbutton "Clean tank" (6)
briefly (approx. 10s).
E) Open the door, sweep the remaining dirt
residue onto the surface strainers and remove
these from the machine.

9. Care and maintenance
Carry out the following maintenance jobs at regular intervals:
A) Check operation of machine.
B) Remove and clean wash arms and nozzles, then remount them correctly.
C) Clean residues from inside of machine.
D) Clean fine-mesh strainer in dirt trap downstream of the on-site water supply.
E) Clean electrode of conductivity-sensitive dosing unit if installed.
F) Descale if necessary as follows (not applicable to GS 14E and GS15E):
•Drain machine.
•Stop detergent supply.
•Refill machine.
•Add decalcifier solution according to manufacturer's directions.
NOTE Observe the safety instructions printed on the packaging.
•Operate the machine: activate the continuous circulation function for approx. 10 minutes by
pressing switch (5) and releasing it again after 10 minutes.
•Drain the machine.
NOTE Under no circumstances should the decalcifier solution be left
in the machine for several hours.
•Start up the detergent supply again.
•Refill the machine.
•Run the machine for a further 10 minutes or so.
•Drain the machine or use the water for the current wash.
During the daily cleaning routine, make sure that no rusty foreign bodies are left on the floor and walls of
the tank, as these can cause even "stainless” steel to rust. Such rust particles may originate from non-
stainless kitchenware, cleaning aids or non rust-proofed supply pipes.
Besides the daily cleaning and regular maintenance routines, the machine should undergo thorough
servicing by a specialist at least twice a year.
We recommend that you have this done by a Winterhalter service technician.
Use suitable cleaning agents and preservatives to treat the outside of the machine. We recommend
Winterhalter Gastronom stainless steel cleaner for this purpose.

11. Optional extras
11.1 Variable rinse temperature
Function of the variable rinse temperature facility
The selector switch ”Rinse temperature” (A) is used to switch between a high and low rinse temperature.
Important:
The high rinse temperature is set at the factory to 85°C and the low rinse temperature to 65°C.
•Press switch (A) once to select the high rinse temperature (indicator lamp in switch lights up).
If you use the high rinse temperature together with the recommended rinse aid, you are guaranteed
optimal drying results. We recommend the high rinse temperature for washing crockery.
•By pressing switch (A) a second time, you can switch to the low rinse temperature (indicator lamp in
switch goes out).
The lower rinse temperature must always be preselected for washing glasses, as a high temperature
can cause glass corrosion (clouding).
12. Special notes
Should the detergent solution become heavily soiled after a day's intensive washing, you should drain it
off, clean the inside of the tank and then refill the tank.
In this case you will need to add an initial dose of detergent again as described in section 5.2.
Please only use detergent and rinse aid products which are suitable for commercial dishwashers. We
recommend our own products for this purpose, as they have been specially developed for our machines.
All weights and measures specified in this manual for detergent and rinse aid refer to Winterhalter
products.
The machine must be protected from freezing conditions in order to avoid damage to water conducting
systems.
These operating instructions are an integral part of the machine!
In the event of a resale of the dishwasher, the operating instructions must be passed on to the
new owner/operator together with the machine.
