To avoid specks on the tank bottom, the detergent should be dissolved in warm water prior to its addition to the
wash tank or the machine should be put into operation immediately after its addition to the wash tank.
The machine is fitted with a detergent control device – control lamp number 12. This light will illuminate as soon
as the detergent concentration is unsatisfactory and, at his time, a further 55 grams of detergent should be
added.
-After the temperature control lamp extinguishes washing may be started.
3. Washing
-Load the dishes into the respective rack.
-Insert the rack into the machine and close the door.
-Release the programme cycle according to the degree of soil of the dishes by pressing the respective
programme button.
-With normally soiled dishes button “1”, programme runs for approx. 1 minute,
-with strongly soiled dishes button “2”, programme runs for approx. 2 minutes.
The main wash cycle, during which the dishes are intensively cleaned from the top and the bottom, is followed by
a 12 second rinse with hot fresh water mixed with rinse aid at a temperature of 85°C.
The selected programme button is lighting up during the cycle.
-After it is extinguished the rack may be taken out of the machine.
On account of the specific heat of the dishes and under the influence of the foamless rinse aid added to the
rinse water, the dishes dry shiny clear within a short time.

by pressing the manual wash button (9) only and the main wash cycle will now operate for as long as required.

products are particularly recommended. All indications about quantity and weight ot detergent, rinse aid and
defoaming agent refer to Winterhalter products.
Should the wash tank water become especially dirty, it is recommended that the machine be emptied and refilled
with clean fresh water.

a year). Then the jets and wash arms have to be cleaned, and if necessary the inside ot the machine should be
descaled and all performance parts have to be checked. As far as electrical components are made accessible,
these works may onIy be done by an expert. In this case please call a Winterhalter engineer.
