My dishwasher does not clean the dishes even though it completed the full cycle

SOURCE: Dishes not clean

If your dishwasher is cleaning poorly, check these:

Water-inlet valve
Internal filters
Drain valve
Spray arms
Water temperature
Detergent cup
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

I put a bottle of CLR in the dishwasher and I did a wash without any dishes. Repeat if needed.

There is a screen on the drain area of the bottom of the dishwasher that needs to be cleaned. It has a plastic mesh screen on it - you can't miss it. Second get an old toothbrush and clean out the little jets on the washing arms that spin around. You will notice these holes are clogged up with calcium deposits etc. Those things done you will have a new dishwasher again. You need to do this every 6 months or so. Also use a rinse conditioner for a while to assure the jets are clean. Good Luck

Heat that is retained in the dishes is largely responsible for drying in this dishwasher. Since plastics do not retain heat very well, they will not dry as well as glasses, ceramics or metal dishes. Rinse aid must be used so that the final rinse water will sheen off of the dishes to accommodate this drying process. The heater element at the bottom of the tub is used to add heat during the drying cycle to aid in this process as well. This model of dishwasher does not have any forced air circulation system. Here are some tips that may help you resolve your drying problem:

• Make sure that you are using rinse aid. Failure to properly use rinse aid can prevent proper drying. Adjust the amount that is dispensed if necessary. Also, check to make sure that rinse aid level decreases over time indicating that it is being dispensed properly.
• The NORMAL WASH and POT & PANS cycles heat the final rinse water up to 140 degrees F. Use these cycles to help the drying process.
• Do not choose the air dry option. This option cuts off the heater element during the drying process. NOTE: The heater element is not turned on during the first 6 minutes of the drying portion of the cycle.
• Do not overload the dishwasher. Load the dishes to allow for proper water drainage.
