Customers Complaint - coee/tea stains left in cups
Cause of problem (1). Not enough detergent is being used. To remove these stains requires a
stronger concentration of detergent in the water.
More detergent is also required in hard water areas, as minerals in the
hard water reduce the eectiveness of the detergent. There are also
detergents available with a built in water softening agent which will
work up to moderate hardness levels.
How to resolve the
problem.
Fill the main-wash detergent cup to the top and for best results also ll
the pre-wash detergent cup. Run on normal or heavy cycles, not Eco.
Use a detergent with a water softening agent.
Cause of problem (2). The product is being over loaded, which is preventing water reaching
the cups on the upper cup racks.
How to resolve the
problem
Advise the customer of correct loading.
