I just moved into a new apartment and the diswasher, who seemed recent, does not clean well. residues get stuck onto the dishes.
I removed the white filter at the bottom but nothing majorely dirty was stuck. Is the problem a poor caused by poor drainage and if so, how do I fix this?

Re: Rinse cycle not rinsing well
The drain hose and recirculation hoses can be responsible for leaks. The drain hose can cause the dishwasher to fail to drain properly. The recirculation hose can be responsible for problems with poor rinsing of dishes.
To access the drain hose remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel.
The drain hose connects to the pump and runs to the sink drain (or to the air gap on top of the sink). The pump has a second hose that recirculates the water back into the dishwasher. The drain hose is roughly 1 1/2 inches in diameter. While inspecting the drain hose, check the recirculation hose as well.
When checking for leaks, feel the hoses where they connect to the pump, for wetness and check the ground right under the connections. If they are wet, it may be a loose or improperly mounted clamp, a damaged pump housing or a leak in the hose itself.
When checking for blockages, disconnect the drain hose from the pump, pinch the wire clamp with pliers and slide it up the hose. Place a shallow pan beneath the pump to catch any spillage. Remove the hose from the pump; wiggling the hose may help to loosen it.
Check the hose and nipple to the pump for any debris. The only way to be certain the drain hose is completely clear is to disconnect it from the sink and run water through (such as spraying a garden hose through it at full pressure). Disconnect the recirculation hose and check it in the same way.
Reconnect the hoses and replace the clamps. Replace the lower panel and restore electricity to the dishwasher.

The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers and make sure that there is nothing obstructing the outlet pipe and the pump. If possible back flush through the outlet pipe and try draining the machine again before using it again.
dishwashers have a rinse aid
dispenser. If your dishwasher has this dispenser, fill it up
periodically and it will release the appropriate amount of rinse aid
automatically at the right time during the wash cycle. This will help
your dishes rinse more cleanly.
Rinse aid in solid form
Some older dishwashers or basic models do not have an
automatic rinse aid dispenser. In this case, you can buy rinse aid in
solid form that attaches to your dishwasher rack. Solid rinse aid can be
hard to find in stores because it is not commonly used, but it can be
Vinegar or lemon juice
Appliance repairmen will tell you that one of the common
problems they see with dishwashers is the buildup of excess detergent.
If there is too much detergent in your dishwasher, your dishes will not
rinse cleanly, no matter how good the dishwasher is or how much rinse
aid you use. To clean the excess detergent that has built up inside your
dishwasher, put 3 tablespoons of vinegar or lemon juice (concentrate is
fine) in the empty dishwasher and run the dishwasher through a complete
cycle with no dishes. Do this twice, for two complete cycles of the
empty dishwasher with only vinegar or lemon juice added. The acid in the
vinegar or lemon juice will break up the detergent that has built up in
your dishwasher's interior.
After you have cleaned the detergent
buildup from the inside of your dishwasher, follow the steps below to
keep the buildup from happening again and to help your dishes rinse
cleanly and prevent residue from accumulating on the dishes.
Gel dishwasher detergent
Switch to a liquid or gel dishwasher detergent. Any brand will do.
Fill one compartment half full
Dishwashers will effectively clean dishes with much less
detergent than manufacturers often recommend. The bleach in the
detergent, combined with the extremely hot water used in the dishwasher
wash cycle, will clean and sanitize your dishes completely, even in
small amounts, and using less detergent helps prevent buildup and
residue from accumulating on your clean dishes.
Fill only one
detergent compartment(the one that snaps closed) half full with gel
detergent. Snap the opening closed and run your dishwasher as you
normally would. Your dishes will come out sparkling clean with no
buildup or residue, plus you'll save money by using less detergent!
It would be real helpful to have you provide the manufacterer and model number to get more specific with solution.
-Have you changes dishwasher soap powder recently? Buy a box of Electrosol or Cascade and see what happens. The ultracheep versions actually have caused cleaning problems, especilly in water-conserving dishwashers.
-Under the lower rack is the sump area with a filter that can be removed, usaully by removing several screws. Pull that filter, rinse is as best you can. Inspect under where the filter was and remove all debris. Watch out for broken glass that is found in most well used diswashers, it is hard to see and sharp! Reasemble the filter.
-If problems continue and if this diswasher is several years old, plan on getting the wash pump motor replaced (or replace the diswasher with a name brand, Energy Star model.) Good Luck!
Please update me with what you found. OK?
I have an older dishwasher also and recently my wife alsocomplained about it not cleaning right... so me being the man I am tried invain to clean the things... Bought new spray arms online and installed them inminutes...now the thing works like new... However I have also found that if theheating element goes bad then that also can mess things up bad... So I wouldbuy new spray arms, and also check out the heating element to make sure it isworking... Here is a tip that will help you with the online buying...
Dishwasher Spray Arms not Spinning
it is likely a control module issue. I will take mine apart this weekend to verify what others have said: solder joint on circuitboard burns out from possible overheating, and DW doesnt go into rinse cycle. Try rinse and hold cycle to see if it stops on its own. mine does, but the other cycles which require the rinse to go to 156 degrees do not; the continue to run until I cancel and drain.
Open the door and check it with a level. If the dishwasher isn't perfectly level, turn its feet (behind cover at floor) until it is level. If the jet bars can be removed, take them off and rinse them out. Make sure they're engaging with the pump outlet properly. There may be a plastic bushing that the main wash arms rotate on. If this is worn, replace it. It will make a world of difference. Finally, make sure you're using enough detergent. I suggest the cheap powdered type. It seems to have the best cleaning ability. Finally, make sure the rinse aid dispenser is set to dispense enough.
I am having the same issue as described above. I think it is either the timer, thermostat (temp assure), or thermostat (temp boost) that needs replacing. The dial gets stucks in both the wash temp boost cycle and rinse temp boost cycle. However, I don't have a picture of the temp assure or boost part.
Does anyone know how to fix this? Thanks.
