3 Product description
The UC series dishwashing machines are designed to be used to wash various dishes. The service
technician authorised by Winterhalter does not program the machine's control unit for use of the dishwashing
machine as a “special machine” for a specific application until it is installed. Alternatively, the dishwashing
machine is supplied ready-programmed for a specific application, but can be reprogrammed at any time.
Programming determines whether the machine can be used either as:
a dishwashing machine (if mostly dishes are to be washed), or as
a glasswashing machine (if mostly glasses are to be washed), or as
a bistro dishwashing machine (if dishes and glasses are to be washed), or as
a cutlery rinsing machine (if only cutlery is to be washed).
If the application changes, the service technician authorised by Winterhalter reprograms the control unit and
thus adapts it to your requirements.
The UC series dishwashing machines are available in the following sizes:
Machine type Width [mm] Depth [mm] Height
1
[mm]
UC-S 460 603 725-760
UC-M 600 603 725-760

Special equipment
Cool (only for glass washing machines)
The washing power of the constantly hot tank water ensures hygienic results. At the end of the wash cycle,
the rinse with cold fresh water ensures the glasses are cooled.
The special benefit: the rinse temperature can be increased at any time. You can always at all times whether
you require cold glasses or wish to optimise drying with a hot rinse.
IMPORTANT: The first wash cycles after activation of the function are performed with hot or warm rinse
water.
Requirement: Machine connection to cold water.
effect (only for glass and dish washing machines)
You use this process to wash at reduced tank and boiler temperatures. Winterhalter detergent and rinse aid
are specially designed for this process and are required for washing at these temperatures.
With the tank and boiler temperatures reduced, you can save energy, which also enables you to reduce your
operating costs. At the same time, the air quality in the room climate is improved in the long-term since less
vapour escapes from the machine when the machine door is opened. The function can be deactivated at any
time.
IMPORTANT: The first wash cycles after activation of the function are performed with hot or warm rinse
water.
Energy
The construction above the machine includes a fan motor and a heat exchanger. After rinsing, the fan motor
draws the moist, warm vapours out of the washing area through the heat exchanger. The cold fresh water
which flows through the heat exchanger for rinsing during the following washing programme condenses the
vapours and is pre-heated. This reduces the energy required to heat the fresh water to the required rinse
temperature. At the same time, the air quality in the kitchen is improved in the long-term since less vapour
(i.e. exhaust) escapes the machine when the machine door is opened.
Requirement: Machine connection to cold water.

Before working with the machine
6
Train the operating personnel in how to use the machine, and inform them of the information in the safety
notes. Repeat the training at regular intervals in order to prevent accidents.
Only use your fingers to operate the touchscreen; not sharp objects.
Have the machine connected by qualified technicians in accordance with the locally applicable
regulations (water, waste water, electrics).
Do not open the machine door whilst it is washing. There is a risk that hot washing solution could be
sprayed out. Cancel the washing programme beforehand (10.2.5).
In case of danger and/or defects, switch off the machine immediately. Switch off the local mains separator
(main switch). Only then is the machine without power.
Contact the Winterhalter Customer Service in case of defects that are not caused due to the local water
or the current supply line. In case of defects resulting from an unknown cause, switch off the machine,
and switch it on again only when the defect has been rectified.
4.5 Daily cleaning and care
Follow the instructions for maintenance and care given in these operating instructions (11).
Wear protective clothing and protective gloves before touching any parts which are covered with
detergent solution (filters, wash fields etc.).
Do not spray off the machine and the immediate vicinity (walls, floors) with a water hose, steam cleaner
or pressure washer.
In order to prevent water from entering into the machine uncontrolledly, make sure that the machine's
plinth is not flooded when cleaning the floor.
Use a brush or a cloth - and not a pressure washer - for cleaning the interior of the machine.
Do not use any scouring powder or abrasive cleaning agents.
When performing daily cleaning, make sure that no foreign objects which may rust have been left in the
interior of the machine. These objects can even cause “stainless steel” material to rust. Rust particles
may originate from non-stainless steel dishes, cleaning aids, damaged wire racks or water pipes with no
corrosion protection.
Clean the outside of the machine using a suitable stainless steel cleaner and a soft cloth. We recommend
Winterhalter Gastronom stainless steel cleaner and stainless steel polish.

Fold lower body panels back
On filling make sure that no detergent gets into the storage container
for the rinse aid, and vice versa.
6.5 Venting the dosing device
The dosing device has to be vented if air has entered into the dosing tube due to the storage tanks not being
refilled quickly enough.
For an integrated dosing device proceed as described in chapter 12.1.
For an external dosing device refer to the equipment documentation.

Integrated water softener (optional)
9
7 Integrated water softener (optional)
Softening the tap water prevents the build-up of limescale in the machine and on the dishes. In order for the
integrated water softener to function properly, the salt container must be filled with regeneration salt.
7.1 How do you recognise whether a water softener or partial demineraliser is
installed in your DeMatik Pi-240?
In the machine there is a reservoir for either regenerating salt or DeMatik Pi-240
regeneration agent.
In machines with a water softener installed: grey
In machines with a DeMatik Pi-240 partial demineraliser: orange
7.2 Entering the water hardness
When the machine is installed, the service technician authorised by Winterhalter measures the water
hardness and enters the respective value.
7.3 Lack of salt display
A display on the screen (15.1) indicates when an empty salt container needs to be refilled.
The display disappears after topping up the salt container as soon as approx. 3 wash cycles
have been complete and some of the salt added has dissolved.
7.4 Adding regeneration salt
Caution
Only add regeneration salt to the salt container.
This salt should be fine-grained (max. 0.4-7 mm grain size). Salt tablets are not suitable.
Do not add any chemicals, e.g. detergent or rinse aid. These will inevitably cause damage to
the water softener.
Caution
After filling start a wash cycle.
After filling, immediately start a washing programme in order to rinse off any salt residue.
Otherwise there is a risk of rusting in the filling area.

Re-install the bottom rotating
wash field.
Check whether the wash field
rotates easily.
8 Inbuilt Partial Demineraliser DeMatik Pi-240 (optional)
The partial demineralisation of the water supply reduces the carbonate hardness of the water. This protects
the machine components from calcification. Delicate articles such as glasses or cutlery are nearly free from
spots after washing and drying
8.1 How do you recognise whether a water softener or partial demineraliser is
installed in your DeMatik Pi-240?
In the machine there is a reservoir for either regenerating salt or DeMatik Pi-240
regeneration agent.
In machines with a water softener installed: grey
In machines with a DeMatik Pi-240 partial demineraliser: orange
8.2 What does the first commissioning look like?
Caution
Have the first commissioning carried out by a service technician authorised by
Winterhalter.
The service technician fills the reservoir with regeneration agents DeMatik PI-240 Reg ST and
DeMatik PI-240 Reg. In addition, the service technician measures the carbonate hardness of
the tap water and saves the value in the machine electronics
8.3 When must regeneration agent be refilled?
2 flashing pictograms indicate that a
full bottle of regeneration agent
DeMatik PI-240 Reg must be refilled.
In addition, a red LED underneath the
Winterhalter logo flashes and a
continuous tone can be heard.
Refill the regeneration agent when
both pictograms are flashing.
Always refill with a whole bottle of
regeneration agent. If too little or too
much is refilled, error message ERR
47 is displayed.
The blinking pictogram, flashing LED
and continuous tone only disappear
when the regeneration agent has
been refilled and the machine
electronics have been unlocked (see
Chapter 8.5).
The continuous tone disappears
temporarily if any button is touched
on the screen or by starting a wash
cycle. After the next wash cycle, the
tone will however be heard again.
INFO: If the continuous tone is
considered to be annoying, it can be
suppressed by a service technician
(P961 = 3).
If not refilled with regeneration agent,
rinsing is still possible but only with
non-treated water. Spots will be
visible on the articles.
