Customers Complaint Coffee/Tea Stains left in Cups

Cause of problem

(1)

How to resolve the problem

Not enough detergent 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 effectiveness of the detergent.

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.

Cause of problem (2)

How to resolve the problem

The product is being over loaded which is preventing water reaching the cups on the upper cup racks.

Advise customer of correct loading.

Customers Complaint Dishes have blotchy marks on them that look like water stain

marks not food

Cause of problem

How to resolve the problem

Not enough rinse aid being used. The water is not soft enough during the final rinse and therefore hard water droplets containing impurities are drying on the dishes instead of running off during the dry cycle.

Confirm that the customer is using rinse aid.

The rinse aid 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.

Customers Complaint Glasses & Cutlery have a Cloudy White film on them and/or Plates

have a White Chalky film on them

Cause of problem

How to resolve the problem

Hard water & not enough detergent being used. Minerals from the water are building up on the dishes or the Water Softener is not set to the correct Water Hardness Level or is faulty.

Once this film forms on the dishes it cannot be removed by normal running in the dishwasher. The dishes will need to be cleaned by soaking them in an acidic solution such as white vinegar and water.

Where a Water Softener is not fitted;

To prevent the build up re-occurring the customer will need to fill both the main-wash

&pre-wash detergent cups to the top with a power detergent and we would recommend running on normal cycles.

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.

Where a Water Softener is fitted;

Set the Water Softener for the correct local Water Supply hardness. Check that the Water Softener is functioning correctly in Diagnostics;
