Dishes in upper tray coming out "not so clean".
Disconnected Upper Arm mechanism and Lower Wash Arm mechanism and checked all the tubes to make sure they are free of any debris and they are. Ran dishwasher with a Thermocouple Probe attached inside and the temperature measured 140° F during the "Normal Wash Cycle" so I was good there, and the water pressure measured 60 psig. Ran again and the same result, the dishes on the bottom tray seem to come out clean but the top tray still has a dirty dish result. I positioned the the Top Tray spray agitator and while the dishwasher was running I would open the door and see if it moved. If I did this real fast the agitator or spray arm would not move, but, when I let the dishwasher run for maybe 10 to 15 seconds and opened the door it would show that it did in fact move so I figured it needed a brief period for the water to get up to this device.
Appreciate any suggestions!
Hi
Thanks for using
FixYa. First of all please check the Water temperature by using a thermometer
inside the dishwasher to measure the water temp. It should be as close to 125
degree F to 140 degree F as possible. Now try using the temperature boost feature
if your dishwasher is equipped with this cycle feature and check if this will
help your wash ability issues.
Now check the
Powder soap by making sure that you store your soap in a dry environment and it
is not stale and clumping together. Possibly try a different detergent like a
liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is
not overloaded.
To check the
proper filling dishwasher will fill with water up to and around the heating
element. If water is more below the heating element, you may have low water
pressure or a problem with the fill valve. Try & listen if it sounds like
it is spraying the water around with enough pressure.
For low water
pressure, try to clean the screen at the entrance of the fill valve, sometimes
the fill valve can fail and not allow the proper water into the dishwasher and
may need to be replaced. And, check the spray arm and pump cover for
splits or leaks. Also make sure that the water is draining and is
not accumulated in the dishwasher, if it is in dishwasher then check
for clogged drain hoses and drain pump.
Low water fills
are a very common trouble maker with today's dishwasher.
Please do rate this solution and
revert for further assistance.
