Why Your Dishwasher Isn’t Draining & How Maintenance Can Help

Ever wondered why the water in your dishwasher refuses to drain, leaving you with a sink full of murky water and a pile of dirty dishes? Picture this: you press the start button, eager to have squeaky clean plates, only to be met with a pool of stagnant water. Frustrating, right?

Common Causes of Water Not Draining in Dishwasher

Wondering why the water is not draining in your dishwasher? Here are some common reasons why this may be happening:

  • Clogs: Food particles or debris blocking the drain hose or filter can prevent proper drainage.
  • Faulty Drain Pump: A malfunctioning drain pump may be unable to remove standing water from the dishwasher tub.
  • Clogged Garbage Disposal: If the dishwasher drain hose is connected to the garbage disposal, a clog in the disposal can affect drainage.
  • Air Gap Issues: An air gap prevents backflow but may become clogged, causing water to back up into the dishwasher.
  • Faulty Check Valve: A check valve prevents water from re-entering the dishwasher after draining, but if it’s defective, drainage problems can occur.

  • Check the Garbage Disposal Connection: Ensure the connection between the dishwasher and the garbage disposal is clear.
  • Run a Rinse Cycle: To test if the blockage is cleared, run a rinse cycle and check if the water drains properly.
