Tip & How-To about Dishwashers
There are a few things to check out if your dishwasher will not drain or won't drain properly. It all depends on which draining system your washer has. Some dishwashers have a pump assembly. This assembly contains a pump, drain impeller, and a wash impeller. Anyone of these parts can get build-up in them or debris and cause them to not function correctly. There is a chance that they just may need cleaned. If you clean it and it still doesn't work, replace the parts. The wash impeller sends water to the arm and the drain impeller sends water to the drain port. Sometimes, there is a belt on the dishwasher that controls the pump assembly. If your dishwasher has a drive belt, inspect it to see if the belt is loose or worn. If it is, change out the belt.
The motor on your dishwasher can also cause issues with draining. To properly test the motor, you will need a voltage meter of some type. You will then need to test the current. The timer on your dishwasher can cause draining problems as well. You can also test the timer to see if it is working correctly too.
The drain hose on your dishwasher can get clogged over a period of time and leave you with standing water. You need to take it off and clean it out. Some hoses are connected to a main drain or a disposer of some type. Make sure the hose is cleared so water can run through it freely. Some dishwashers have a drain valve that opens to release water. This valve is controlled by the solenoid. Your timer effects the valve opening. If your timer is defective, the valve will not open. If your timer is good and you know it is for sure, the valve and solenoid may need replaced. Remember, all dishwashers are built differently and may contain more/less of the parts mentioned. Be sure to check all parts because multiple parts can be defective. Some parts can cause other parts to not work correctly as mentioned above. Make sure you consider that.
It is very important to remember to unplug the dishwasher before you work on it. Be sure to test and inspect each part before you decide to change it. Whether is it unpluging the washer, removing the fuse, or killing the breaker, make sure it is done. It is dangerous to work on anything electrical.

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound. If it seems as a low water pressure then check the fill valve.
Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. Check the drain hose for any visible clogging, remove if present. If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you'll need to clean the drain filter and drain pump.

The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes.
Hope this helps...
