Top shelf wont wash - Dishwashers

Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!

Check the center wash arm assembly. If the center wash arm isn't getting water, all of the dishes in the upper rack will come out dirty. Check to be sure the center wash arm assembly is mating properly with the water supply nozzle in the back of the dishwasher. Also check to be sure the little holes in the center wash arm aren't clogged or blocked. * Run empty cycle using vinegar and baking soda lime scale problem will resolve.

under the top shelf or in the top of the machine is the water rotor. remove this and ensure none of the holes are blocked, also ensure your macine is not running on 1/2 half load as this may only activate the bottom. it should be set to full load to use both. if rotor bloackage is the problem use somthing to clear it. and also check the bottom one. also remove and clean the inner filter as debris may have got past it and getting pumped to your rotors.

I hope this was useful

Make sure the center loading is not obstructing the water jet to the top shelf. Top shelf is only for glasses and saucers , use Jet-Dry .Pre rinse and clean bottom pan strainer from dirt debris.

You may have debris in the sprayer arm jets. It is usually simple to remove the sprayer arms. Then rinse them well using the sink sprayer for forceful water power. I have sometimes had to use a tweezer to remove bits of plastic, paper, bone, or food particles. Once you've remove the debris, rinse well forcing water through to dislodge any other debris. Once you've reattached the sprayer arms, you should have cleaner dishes. Also, some brands of dishwashers have a pipe that runs up the inside back wall and connects to a pipe that runs under the top shelf. Water flowing through this pipe under the top shelf propels the sprayer arms. If the connection at the back is not flush with the "propel" pipe there won't be enough water pressure to turn the sprayer arm. Check to see if your dishwasher has this type of set up.
I hope this works. If it does, please let Fixya know by rating my solution.
Good luck!

Many reasons...here's the most common:
1. the two latches on either side of your real shelf (Above the trunk (Boot) space. Unlatch and re-latch them firmly.
2. Make sure the rear shelf id down firmly Sometimes those switches don't engage.
3. (This one got me) If you had a dead battery or had battery disconnected for any reason, cycle all the windows up and down a couple of times then try the top.

cheap trick...take a glass and put it on the top rack...right side up run dishwasher for about 4 mins is the glass full with water,no ok than check your drain hose the water is sphion out during wash,,lift it the height of unit..keep me posted

possibly low water pressure...

racks might be in backwards if it's an older model with wheels on shelf system... rubber bumpers should face out...

could be a blockage in the upper sprayer arm... or the upper arm had come off and was remounted in a position that doesn't line up with the jet of water from below...

could be bad loading technique... sounds simple enough but you should never put large bowls or pots that lay horizontally on the lower rack because it really screws up the cleaning effectiveness. Large items should always go on the top rack or be washed by hand if they don't fit on the top rack.

Check your trunks storage shelf. It needs to be down for the top to let back. I had the same prob. then to find out it was only the shelf. Hope it works for you

After some experience with our own fdw60 with the same problem, we now put all pots and pans on the top rack. Putting them on the bottm appears to stop the clean water rinse reaching the top rack. All washes since have been ok.
