Common Dishwashing Problems - Ecomiser SU-01 Manual

As with any new machine, it sometimes takes using it a few times to learn to operate it properly. If you
are having minor performance problems with your dishwasher, read this section before calling for
service. It may save you time and unnecessary expense.
POOR WASHING PERFORMANCE
- The dishes may not be loaded properly. Make sure that soiled surfaces are facing downward or
toward the center of the dishwasher. Also, make sure that the bowls, pots, etc., are not stacked so
closely that water can't reach the soiled surfaces.
- Make sure you are using the appropriate program settings for the dirtiness of the dishware.
- An item may be obstructing the rotation of the impeller. With the rack loaded and in place, manually
turn impellers to ensure free movement.
- Dishwasher detergent should be fresh and stored tightly closed in a cool, dry place. Old or caked
detergent will not dissolve properly.
- Dishwasher detergent may be inferior. Try a different brand.
- If you have hard water in your area, try adding more detergent and increasing the amount of rinse
aid dispensed. Water hardness must be controlled to 4-6 grains for best results.
- Check that the impeller jets are not clogged.
POOR DRYING PERFORMANCE
- Make sure the rinse aid is enough.
- Do not overload the dishes and be careful to avoid nesting.
- Load items with concave bottoms tilted so as much water as possible will run off.
- Dishes washed in higher water temperatures will dry faster.
- Certain plastics may need to be towel dried. Always check the manufacturer's suggested care
instructions before washing plastic in your dishwasher. Even dishwasher-safe items should be
loaded in the rack, away from the heating element.
- Check the amount of rinse aid is proper that it is fresh.
WASHING ITEMS
Ecomiser has no control over what is put in dishwasher once installed in a user's place. You are
solely responsible for what you wash in your Ecomiser SU-01 / SU-02 models dishwasher. Most
common dishware items can be safely washed in an automatic commercial dishwasher. If you have
any doubts about a particular item, check with the manufacturer to see if it is dishwasher safe.
- Some high-acid foods can discolor plastic. You should rinse these items.
- When you load the dishware, be sure dishware is securely in place and will not fall over or strike
against each other during the wash.
- Load glasses between the tines, not straddling them.
- Move the rack in and out slowly to avoid slamming the dishware together.
- Make sure not to load dishware so high that the upper impeller could strike them.
- Do not overload the dishwasher.
STAINS AND DISCOLORATIONS
Stains or discoloration on dishware could be caused by a number of things:
- Too much iron or manganese in the water can cause yellow or brown marks on your dishware. You
should consider installing a water filtering system.
- Coffee and tea stains usually have to be removed by hand washing. Be sure to rinse these items
thoroughly before putting them in the machine so there is no bleach residue on the dishware.
