Ensure the procedures and frequency recommended by the detergent supplier are followed,
also ensure that the correct products and equipment are used. In order to avoid damages to
the machine, do not exceed the recommended dosing and at the end of the procedures, rinse
thoroughly.
Hygienic care
A thorough cleaning of the machine is essential. For this operation the use of sanitizing
detergent/disinfectant is advisable. The use of such a product offers the following
advantages:
•
guarantee for perfect hygienic conditions, as it is composed of active detergents and
disinfectants.
•
maintenance of perfect hygienic conditions, also if the machine is not used.
After completion of above procedures the machine has to be rinsed by completing a short
washing cycle without load or by using the sanitizing cycle (optional).
Removal of lime scale encrustation’s
In case of hard water a periodic descaling should be carried out to ensure hygiene and proper
operation.
Optimum results
Traces of dirt or marks are the result of a possible deficiency in the wash operation. If this
problem occurs ensure that the wash nozzles are clean and that there is an adequate water
supply/pressure available. Also check the following points
•
wash nozzles are not blocked
•
water supply temperature (probe 1) is 50/55°C (excluding machines with heat recovery
unit or machines functioning with cold water feed)
•
prewash temperature (probe 2) is 40/45°C
•
wash temperatures (probes 3....6) is 55/60°C
•
rinse temperature (probe 7) is 80/85°C
•
detergent is used in the correct concentration
•
filters are clean
•
water is not too dirty
•
dishes are not stacked one upon or inside the other, as the water needs to circulate freely
and directly contact all surfaces.
Prolonged standstill of the machine
In case of a prolonged standstill lasting several weeks it is advisable, in order to avoid
unpleasant odours and the accumulation of dirt, to empty the machine, refill and run with
clean water.
If the standstill lasts for a very long time, it is recommendable to lubricate the stainless steel
surfaces with Vaseline oil.
