Aquarius model dwf31. Why doesn't it clean items in top rack?

it would be improbable that you put too tall an item on the top rack every time you wash, but it is also impossible to check without a see thru tub. Just make sure there are no tall items and maybe lower the top rack.
Some dishwashers have the top arm on the bottom of the rack and use a connection in the back when the rack is pushed in. If yours does make sure it isn't deformed and not making properly.

A couple of scenarios could cause this problem but the simplest might be the way the dishwasher is loaded. The upper spray arm rotates when water is pumped through the vertical supply tube and into the arm. Make sure that you are not loading the lower rack with items that interfere with the rotation of the upper arm rotor. It might also be a good idea to verify that the feed tube that goes to the spray arm is securely connected to the vertical supply tube.

Good Afternoon Stephanie,

I understand the spray arm is not raising all the way in your Frigidaire dishwasher, model# FDB750RCC. I also see that the dishes on the top rack are not getting clean due to this. The spray arms are stationary where they are attached to, other than turning due to water pressure. Please try the following solutions:

• Choose another cycle for longer washing time.
• Check rack loading section for proper loading-avoid nesting items.
• Home water pressure may be too low- should be 20 to 120 pounds per square inch (psi).
• Check incoming water temperature. It should be at least 120 degrees F.
• Select HI-TEMP WASH option.
• Check water hardness. For extremely hard water, it may be necessary to install a water softener.
• Use fresh detergent.
• Check to make sure funnel in top rack is not blocked.
• Make sure items are not blocking the spray arms, preventing them from rotating.


I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

Hi

If the top rack of the dishwasher doesn't get clean, check your appliance to see if you can fix the problem.
First check the spray Arms to make sure the holes in the spray arms are free and clear of debris. Your dishwasher should have several spray arms, including one at the bottom of the tub, one under the top rack, and possibly a third spray arm on the top of the tub. Sometimes food and mineral deposits can block holes in the spray arms, preventing water from spraying effectively. If this occurs, warm some white vinegar and pour it into a spray bottle. Spray the holes with the vinegar and dislodge debris with a toothpick or large safety pin.

Then check to see if your dishwasher has clogged filters. Filters generally cover the drain valve area to catch debris as the water drains from the dishwasher. Many dishwashers have maintenance-free filters, but your dishwasher may have filters that need cleaning. Read your owner's manual before you perform any filter maintenance to avoid damaging your dishwasher.

Check your water temperature to make sure it's hot enough. Water that is under 120 degrees Fahrenheit may not be hot enough to clean dishes effectively. Turn your kitchen hot water tap on and wait until the water warms up completely. Fill a cup and measure the water temperature with a kitchen thermometer. If the water is less than 120 degrees Fahrenheit, turn your water heater up to 120 degrees.

Load the top rack properly. Place cups and bowls upside down in the rack and don't nest dishes because this can prevent water from reaching dishes. Don't overload the top rack. Instead, position each item so the dirty areas of the dishes will receive full contact with water spraying up from the main spray arm located beneath the top rack. Prevent items from hanging below the top rack, which could prevent the spray arm from rotating.

your top spray arm is blocked and not rotating,remove it from top basket and thoroughly clean it paying particular attention to the holes right at the ends these are angled to drive the arms round if they block up the arms will not rotate.

Please post the model number of your dishwasher here.

I am not familiar with the HorPoint Aquarius dishwasher, but if it is a newer, water conserving, energy saving model, it ~might~ have a check valve that switches/alternates the water from the lower to the upper rack (Other manufactures do this, including LG.)

I know you think I am nuts, but your problem ~may~ not be the wash arm. It really sounds like your heating element is not working, which then does not get the detergent powder up to the high temp it needs to activate the cleaning ability.

Also, buy a box of name brand detergent powder and use it rather that an ultra-cheap box. It really does make a difference with dishwasher detergent.

Good Luck!

Please post back here with what you find, OK?

Lift off the rotating arm,and soak it in lime away, or crc. It's probaly has lime deposits,keeping the pressure down

Almost all of the problems mentioned above will be solved by having the owner buy a name brand detergent powder (like Electrosol or Cascade) and using a little less than you think you should.
For those who continue to have problems with poor cleaning, you need to remove the lower spray arm (pull straight up firmly, then out) and then remove the 9 screws that hold the filter in. Using a flashlight, inspect everywhere in the sump area (be careful of broken glass!) Remove all debris and especially look for something blocking the white check valve that is driven by the Vario motor to control the alternation between the upper sprayer arms and the lower arm. Reasemble and test.
If inside dishwasher is a mess with white mineral deposits, recommend you place a bowl filled with white vinegar on the rack of your empty DW. Start a quick cycle with no detergent added.
Check out how clean it is when you are done!
If you have problems after this, please post back what you are seeing.
Good Luck!

open machine when running and check both spray arms rotating - you will get a bit of water out. if spray arms not rotating, usual cause is debris in the arms. the spray arms only rotate by water jetting from angled jets at the end of the arms. take them out and make sure all debris removed

MY DISHWASHER TASTES OF SALT AFTER EVERY WASH .I HAVE RINSED IT THREW AND IT STILL THE SAME
