How to Resolve Problem
a) One of the dishes / cutlery / utensils has fallen through the basket and
jammed the spray arm, remove the obstruction.
b) Filter plate, drain filter, or drain filter access panel is not installed correctly
and is causing the spray arm to jam.
Advise customer of correct loading.
Advise customer about reduced water temperatures (up to 20º C / 70°F lower)
wash times when using Fast and Eco cycles.
Fill the main-wash detergent cup to the top & for best results also fill the
pre-wash detergent cup. Run on normal or heavy cycles not Eco.
Confirm that the customer is using rinse aid. The rinse agent may need to be
turned up to a higher setting (4 or 5 lights) and for optimum dry performance
run the DishDrawer on normal or heavy cycles not Eco.
Check that the rinse aid dispenser is dispensing correctly in diagnostics.
Once this film forms on the dishes it cannot be removed by normal running
solution such as white vinegar and water.
To prevent the build up recurring the customer will need to fill both the
main-wash & pre-wash detergent cups to the top with a powder detergent and
we would recommend running on normal cycles. On models with a water
softener, modify the setting.
In problem areas with very hard water the customer may need to use a
detergent additive designed for use in hard water areas or fit a water softener
to the incoming water supply or purchase a Water Softener model.
