Does water drains out properly ?

SOURCE: GE Profile Dishwasher Not Cleaning

I removed the outer metal door cover by removing most of the phillips roundhead screws. The two screws closest to the latch should not be removed (they hold plastic pieces that help hold the outer door cover in place during reassembly), and the two flathead screws on the side of the door near the hinge should not be removed yet (they attach the pump). The door cover also has two small hex bolts on the bottom - these should be removed, too (or at least loosened). I removed them.

The outer door cover has two flat flexible wire bundles (for the buttons) that attach to the door using "quick-connect" push-pull connectors. One has a small tab which must be slightly depressed. Gently but firmly pull these out. Set the door cover aside.

I removed the pump by (one) gently but firmly removing the short (2" or so) gray rubber tube from the bottom of the detergent reservoir (NOTE: any detergent remaining in the reservoir will immediately drain on the floor at this time -- I let it drain most of the detergent into a cup, but then I taped a tapered wood screw into the opening to serve as a plug); (two) removing the 90 degree rubber fitting that attaches to the door; (three) disconnecting the motor wire electrical quick-connect; and (four) removing the two flathead screws that attach the pump to the door.

My (rotary peristaltic) pump has a black flexible tube that was clogged with solidified detergent. I verified the pump worked by first connecting the pump to power from the wall outlet. I used an old extension cord, cut the ends, crimped some small connectors that did not fit well to the pump connector, then taped the whole thing to help prevent a shock (I did not feel comfortable with this, but I did it anyway. Use caution. If I have to do it again, I would have used a pipe cleaner or wire instead of operating the pump as described below.). The pump motor is rated 110 volts ac., and the pump was operating fine. I think I got lucky (the pump spun the correct direction). It may be that if I reversed the wires, the pump might have operated backwards.

I then held the pump inlet hose under hot water in the sink for about 10-15 minutes, occasionally squeezing the hose, until the thick detergent had dissolved. During this time, the pump was pumping the water out the outlet.

I put everything back together, and the dishwasher cleans again.

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.

if the dishwasher has not been used for a few weeks, the water in the sump that goes into the pump will evaporate causing the pump to freeze up. usually you can turn the fins inside the motor to free it up. make sure the dishwasher is not on when you do this.
