Mod m.d.c.5100aww ser28126829ax I had a repairman come out. He said the "sprayers" are plugged. I'm on a fixed income. With my bills I can't afford to get it fixed. Trying to fix it myself. I have the bottom sprayer unsnapped & can't get it back on. Thank you Don

Most dishwashers dispense the detergent via gravity and the sprayer arms spraying against the soap dispenser once the little door flips open during the wash cycle. Since it sounds like the soap door is opening I would look at the sprayer arms and make sure they are free of food particles or other debris that might be keeping them from rotating and spraying properly. Here are some instructions for performing this check.

Remove the lower dishrack from the unit. Reach into your dishwasher and spin the lower spray arm. Take note of whether or not the arm moves freely or if its movement is restricted. It should not be restricted in its path of motion. Now gently pull up on an end of the spray arm. The spray arm should be free to wobble up and down. Unscrew the arm retaining knob (some of these are left hand threads) and take the arm out for inspection and carefully examine the spray arm seams. If they have split or are damaged, the dishes may not receive the amount of water pressure required to fully clean the dishes or to rotate the arm properly. What’s more, if water is in fact spraying out of the spray arm from its seams, it is possible that it can cause your dishwasher to leak. Make sure there is no debris in any of the holes.

If your dishwasher has a spray tower, pull up on it as far as it will go and then let it fall back down. Again, this movement should not be restricted. It should be a fluid and smooth motion. Also, unscrew the spray tower and examine it for any debris or foreign objects. Remove any that you find.
Gain access to the upper spray arm by removing the upper dishrack. Perform the same tests for the upper spray arm as you just did for the lower spray arm. Keep in mind that the upper spray arm may not wobble as much as the lower spray arm.
On a final note, some dishwasher models have a water tube that meets up with the upper spray arm once the upper dishrack is pushed back. It is a good idea to check to make sure this tube is aligning properly with the upper spray arm and that this has not split or is damaged in any other way.

    "Make sure the detergent dispenser and/or spray arms are not blocked ..."
    ...with dishes or utensils so that water and detergent can circulate properly.

    Check filter screen often and keep it clean. This prevents redeposit
    of food soil on dishes and also maintains efficient operation of the
    machine.

    Use the proper amount of detergent for best results. Too little will
    not clean properly, too much will leave spots. Always use automatic
    dishwasher detergents. Add detergent to dispenser just before using.

    Store the detergent in a cool, dry place to prevent caking.

Samsung Dishwasher error light "heavy" or leakage error


I had the same problem, SAMSUNG did not want to tell me how to fix so I jumped in with research I found that after you remove the power supply, i.e. plug, 1) you need to remove the dishwasher and turn it upside down. 2) There is a white sensor tray; 12x12 approx. on the bottom held in with two screws, remove the screws and use a flat head screwdrider to undo the clips holding the tray in place. 3) Dry the tray and sensor tips with a towel and replace the tray. Bammmm, you have just fixed the LE(leaking error) code error.

The top sprayer is not spraying any water and the middle sprayer has water except it does not have enough pressure of water to spin around the sprayers. What do I need to do to fix the problem


All sprayed water comes from the pump located at the lower deck. Remove all parts from the lower spray assembly (note position and orientation of each part) down to the deck. There should be a large filter screen at the bottom that commonly becomes plugged with food and hard water deposits. Soak the screen in a mixture of hot water, white vinegar, and dish detergent for an hour or two until the deposits come free. Check around the pump area and the deck openings for any debris plugging. Reassemble in reverse order, but check all three spray arms for spray hole plugging or split seams. Hope this helps!

The dishes on the top are not getting clean what can be the trouble? Tea stains and grit are left in cups and glasses.


I had the same problem and fixed it by disassembling the lower spray arm and return filter, and cleaning all the junk out.
Most dishwashers have 'risers' that bring the water up to the top sprayer or arm located under the top rack. If the recirculating pump is plugged even a little there won't be enough volume or pressure to get the water up there.
Test this by putting a dry muffin pan in the top rack, flat, and running the dishwasher for a bit. If there is no water on the top (or the bottom) either the top sprayer or the sprayer arm underneath the top rack is not getting enough volume.
To fix this you need to clean out the screen and filter, where the water returns to be recirculated. If you don't have any confidence to remove the parts and clean it out yourself, get an appliance repair person to do the job.

Kenmore Elite Dishwasher - leaks from Overfill Protection Float


I had the same problem, but mine leaked every time. I have a kenmore ultra wash dishwasher no. 665.15762. I took the bottom rotating sprayer off and found that the plastic piece under the sprayer had a few loose screws and the rubber gasket, under that piece, had blown out at the corner facing the overfill protection float. I took out all the screws and re-mounted the gasket in place and put all the screws back and tightened them. It solved the problem. I hope that this helps others.
