Tip & How-To about Dishwashers

HOW TO TROUBLESHOOT A DISHWASHER THAT WON'T DRAIN

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.

Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Drain Solenoid Kit If the dishwasher won't drain, the drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced. The drain valve is not repairable Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

HOW DO I DRAIN WATER FROM MY SMEG DISHWASHER


There is a screen filter at the bottom of most dish washers, if the screen gets dirty it probly won't drain properly. Check the screen and clean if neccesary. If not that, then pump may be getting weak.

dishwasher won't drain properly. Dishes aren't properly cleaned


Hi



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...

drainage problem


Regardless of the brand dishwasher, they all have the same fundamental plumbing. so.. you need to check a few basic things first..

1. Have you cleaned the drain filter or screen?
2. Is the drain hose kinked or restricting water flow?
3. Is your dishwasher pump blocked internally or the hose entering or exiting it ?
4. Is the house drain ( meaning : where that hose drains water into) restricting water flow? ( back pressure or clogged?

Any one of these conditions will manifest itself as an undrained dishwasher.. Hope this gives you some things to check and you get your problem resolved...
Good Luck
