Check to see if you have any switches on your dishwasher that could by pass a rinse cycle. Use a hotter temparture when washing, Check your water level,check your filters on your inlet hose top and bottom. When it gets to a rinse cycle you should hear it drain out and bring in fresh water. you could change to a liquid detergent. Dont over load your dishwasher. make sure you are using rinse aid and try adjusting it up one setting. Shiney glasses means your rinse add is working. NZL

You might have something bouncing around in the wash pump inlet in front of the "chopper". Remove the lower arm and upper arm supply tube. Remove the screws then remove the screen, accumulator and inlet protector. You should see debris in front of the screen. 0ca22aa.jpg

SOURCE: Soap dispenser

To remove the Outer Door, open the door and remove the
six T-20 Torx screws located three on each side of the Inner
Stainless Door, Fig. 7-1.
Return the door back to its upright position, and bring the
bottom of the Door Panel out toward you, then slide the top of
the panel down and out from under the Facia Panel, Fig. 7-2.
As the Outer Door is being removed, the left or right Door
Guards may shift or fall out of place, Fig. 7-3.
To reposition them, slide them back in over the hinge, Fig. 7-4,
lining up the door guard square tab with the hinge lever
square notch.
Please note: Door Guards must be in place before
reinstalling the Door Panel. Door Guards are
not used on SHI or SHV models.
Once the Outer Door has been removed the following components become visible.
1. Dispenser Assembly
2. Condensation Tube
3. Upper Wiring Harness
4. Door Guards
5. Door Seal
6. Bituminious Insulation
7. Cloth Fiber Insulation
Also note the Toe Kick, item 8, and the Toe Kick Mounting Screws, item 9.
The Dispenser Assembly operates via a PTC
Actuator (wax motor), item 1.
When voltage is applied to the Actuator it
advances a Combination Lever, item 2.
The Combination Lever allows the Soap Door to open,
and later in the cycle dispenses the Rinse Agent.
To remove the Actuator, first disconnect the
Wiring Connector. Then, using a small
screwdriver, release the locking tab….
…and bring the Actuator out from the Dispenser.
Please note: The Combination Lever cannot be
replaced individually, but only as
part of a new Dispenser Assembly.

SOURCE: Dishes not being rinsed thoroughly in our GE Nautilis Dishwasher

If your dishwasher is cleaning poorly, check these:
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it. 

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it. 

Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

Tools required: 

Adjustable wrench

Multi-Screwdriver 

Pliers 

Step 1. Disconnect the dishwasher from its power source. 

Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful. 

CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair. 

Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here. 

Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home. 

Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s). 

The inlet valve is usually near the front of the dishwasher. Attached to the valve you’ll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher. 

Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel. 

CAUTION: Water supply line may be hot. 

Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.

Step 6. Remove the screws holding the valve to the dishwasher frame. 

Step 7. Label the wires to the valve so you’ll be sure to reattach them correctly. 

Step 8. Remove the wires from the valve. 

Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve. 

Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly. 

Step 11. Install the new valve in the reverse order of the removal instructions. 

Note: The water supply line is under high pressure. Be sure to tighten the fittings properly. 

Step 12. Turn on the water to the machine, and check for and correct any leaks. 

Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test. 

Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle. 

Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

  • Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.


  • Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.


If your filter is clogged, it may be causing the cleaning problem. 

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary. 

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps. 

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

Is it possible to get RINSE ONLY cycle?


Unlikely. People don't buy dishwashers to do half the job themselves. If you are washing them you may as well rinse them and stand them in the rack.

There may be a light soil cycle.

Make model manual

Or check the manufacturer website under support.

Film on dishes post cycle is caused by 2 things.... Poor water flow during the wash / rinse cycle.... i.e clogged sump inlets or restricted drains. Clean the drain hose first. Start at the cink connection and clean EVERY connection and in-line componenet from the port hole at the sink connection all the way back to the drain hise connection port at the dishwasher.

If you still have dirty dishes post cycle after drain cleaning... then remove the lower wash arm support and clean the accumulator / sump area thoroughly. See this link: (items 1 and 4) http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140844&diagram_id=28222738#d28222738

Test again.

If the problem persists you will have to gain access to the pump impeller. Inspect the impeller, and pump housing for damage. UNDER the dishwasher. Item 22 of the above link.

This should get your diswasher performing properly again.

I used this model number as a reference: GU2400XTPB1

Thanks for choosing FixYa,

Either:

  1. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller. Disassemble and clean pump if necessary.
  2. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.

After wash cycle and rinsed cycle there were suds


Make certain you do not use dish soap when rinsing the dishes. Make sure you only use DISHWASHER soap when running the DW.
In fact,there is no need to rinse dishes. Remove visible scraps and put them in the DW. If it is a quality DW it will clean your dishes. Do not crowd the dishes in the DW. Most JennAir DW's are quality. Make sure the top rack can get washing action from the bottom spray arm. No pots or other water stopping utensils on the bottom rack.

After washing cycle dishes do have not been rinsed


Not Rincing properly normally referrs to a few things to check. 1)remove both rotors and clean holes properly. Once dishes have been stacked make sure the rotors can turn freely. Try now. Suggest you clean the sieve on the incomming water pipe.(at the valve.)

Lost manual, wheres rince aid comp


forget the built in rinse aid, it only works for a couple minutes during the whole wash cycle. go out and buy the rinse/aid or jet/dry package that hangs on the racks and works during the whole cycle. of course use only cascade powder soap and sparingly.

Whirlpool gold builtin dishwasher


Do not recommend premeasured tablets, usually too much soap. If pre-rinsing dishes use only 1 or two teaspoons of soap in the main wash cup..do not put soap in the prewash cup. Excess soap can cause oversudsing and make the soil sensor think the dishes are real dirty initiating additional wash cycles. Use rinse-aid for better drying performance
