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.
A. FOOD OR STARCHY REMAINS LEFT ON CROCKERY
May be detected by running the tip of a finger over the surface of a dish or by wiping with iodine.
This gives a blue/black colour to even the smallest trace of starch. Dried on starch or food soil
should be washed off manually before placing items back into the dishwasher.
1. Food remains not removed prior to washing
Ensure that surplus food is removed and that heavily encrusted or burnt on remains are
pre-soaked.
Ensure that Pre-Wash Programme is used if soiled dishes are being stored in the machine prior
to washing.
2. Spray arm nozzle blockage
Check spray arm and check that the strainer is seated down correctly.
3. Deposits on cups and glasses
Deposits of a sandy like substance etc., in cups and glasses in the upper section of the basket
which looks like resin are generally caused by the spray arm not functioning properly.
Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water
pressure.
Low water quantity in machine.
4. Poor arrangement of load or overloading
Ensure that loading allows sufficient force of water to reach all dishes.
In certain cases it may be necessary to leave some spaces empty to ensure good results.
5. Blocked filter or kinked drain hose
Ensure that these items are satisfactory otherwise excess food soil will be present in the machine.
6. Low wash temperature
Check that correct programme is being used and that the thermostat is operating at the correct
temperature.
7. Insufficient detergent
Food soil may not be completely loosened and will not be kept in suspension in the water.
If in doubt, too much detergent does no harm, but too little in the long run does.
If dishes are heavily soiled add extra detergent. Remember - too little detergent causes foaming.
