If your dishwasher isnt draining, you will need to check the sinks drain for clogs and blockage caused by food, debris and waste, and that the drain hose connection to the sink is straight, not pinched shut, kinked, bent or damaged. Depending on your local regulation, the hose may be connected to the sink with an air gap, or have a high loop to prevent backflow and ensure proper drainage.

The Drain Pump Is Damaged

Just like dishwasher filters, a drain pump can easily be blocked by leftover food particles and built-up grease. This will prevent the water from being drained after a washing cycle. Any debris that may have found its way to the pump can usually be found near the impeller .

Foreign objects, such as broken glass, can also easily slip into the drain pump and prevent the pump from working. You should be able to hear the pump struggling if there is a problem here.

Checking the drain pump requires access to the bottom of the dishwasher. This means youll need to disconnect the inlet hose and remove the base plate.

Cause: The Drain Hose Is Clogged

If the dishwasher is not draining, a clogged drain hose is often responsible. If you are lucky, you will be able to clear the blockage with vinegar and baking soda. Otherwise, the drain hose will need to be disconnected, which can involve disassembling the dishwasher. If you need to disassemble the dishwasher, you will want to check the drain pump, and possibly the check valve while you have access to it.

The Presence Of Clogs And Kinks In The Drain Hose

Consider oil, fats, and grease when your dishwasher drainage slows down/ fails to drain. Identify more culprits affecting the garbage disposal in your dishwasher.

If everything else fails, replace the connecting hose. This hose connects the dishwasher machine to the disposal. Over time, the hose becomes clogged and kinked, which slows down the drainage.

Replacement is the only option if the drainage is painfully slow or non-existent.

Instructions

  • Next, remove the casing and the diverter, a plastic cap that covers the air gap.
  • Remove any food particles. You may need tweezers or needle-nose pliers.
  • Use a small tube or pipe brush and warm, soapy water to clean the inside thoroughly.
  • If there are clogs deep in the air gap, you may want to feed a slim drain snake through the air gap until you see it appear in the garbage disposal area. That way, you know the entire pipe is clear.
  • Reassemble the air gap, restore the power, and run the garbage disposal.
  • Next, run a wash cycle without dishes to see if the problem is still present. If you still have water pooling in the bottom of your dishwasher, try another solution.

    Why Use A Dishwasher Anyhow I Can Wash Dishes By Hand

    If your dishwasher breaks down, its easy to forgo costly dishwasher repair and simply hand wash and dry dishes. But heres the rub: Washing dishes by hand consumes 4-5 times more water than dishwashers and that adds up on your utility bill.

    Of course, there was a time when dishwashers used a lot more water. But now, the Department of Energy regulates the amount of water modern dishwashers can use. So, if your dishwasher was manufactured after 2013, five gallons of water is its limit. On the other hand, the US Geological Survey estimates that it takes anywhere from 9 to 27 gallons of water to hand-wash a load of dishes.
