Hello ddux97 - Here are a few simple troubleshooting tips
that may help you resolve this issue:
·
Do you have hard water? Hard water is the primary
reason to cause soap residue. Water hardness can be determined by the local water supply
company, water treatment company or via a water hardness test kit, which can be
found at local part distributors or hardware stores. Some kind of water
softening is recommended, in areas where the water hardness is 12 grains or higher.
For very hard water a home water softening system would be recommended.
·
Will the upper spray arm rotate freely? If it
does not, then there isn't enough
water being pumped to the spray arm or the full flow of water is not making it
to the upper spray arm. Remove or replace the spray arm assemblies since
it is possibly damaged.
·
Confirm that the drain hose is strapped up
properly under the sink to prevent the water from siphoning out during the
cycle.
·
Dishwashers require the water inside the unit tank to be 120F to
perform properly. Best way to ensure this happens is to run the sink faucet
until the water comes out hot before the dishwasher is turned on. This will
ensure that hot, 120F water goes directly into the dishwasher when it starts
to fill. When checking dishwashing detergent boxes and with detergent
manufacturers, the compounds in the detergent need water temperatures to be
between 125F - 140F to dissolve in the dishwasher. The water pressure
should be 20-120 psi (pounds per square inch). If it is too low, I recommend
reaching out to a plumber to further assist you.
·
Rinse aid dispenser should be checked and filled about once a month
depending on the number of washes you do in a month since this will cause
cloudy dishes and soap residue.
If these basic troubleshooting tips prove ineffective, then
at this point, I would recommend having a service technician to diagnose the
problem before investing in unnecessary parts.
