Page 16: General Dishwashing Information
Indesit Company GENERAL DISHWASHING INFORMATION NOTE: - Many faults occur over along period of washing incorrectly. Correcting faults may not immediately cure a problem, e.g. several washes may be necessary to give better results. POOR WASH RESULTS A variety of factors influence wash results and some of the more common are listed below.
Page 17 Indesit Company B. WHITE COATING ON DISHES AND INSIDE THE MACHINE 1. White coating or scale Detergent not only loosens the remains of food but, together with the calcium salts in the water, forms water-soluble compounds which prevent the appearance of the white calcium coating or scale.
Page 18 Indesit Company E. POOR DRYING 1. Correct amount of Rinse Aid The purpose of rinse aid when added to the water of a final rinse is to allow the water to run off the dishes as a complete film so that no water-run marks or calcium are left. To enable this to happen it is essential that the correct amount of rinse aid is dispensed.
Page 19 Indesit Company 2. Nickel Silver (German Silver) is an alloy of copper, nickel and zinc, and when subjected to heat in dishwashing solutions the metal acquires a yellow colour. Maintaining this alloy in attractive condition requires frequent polishing and it should not be washed in a dishwasher.
