While Cove dishwashers provide superior cleaning power and reliability,  it can fall victim to the same draining problems as other brands. Why is there standing water in my dishwasher? A clogged filter blocks water from exiting, leaving puddles inside the tub. Troubleshoot a Cove dishwasher not draining with these likely causes.

5 Reasons For a Cove Dishwasher Not Draining

As alarming and frustrating as a Cove dishwasher not draining may be, it can usually be resolved with some cleaning and maintenance. The first step is to remove any standing water left inside the dishwasher tub. To manually drain a dishwasher, scoop out as much water as possible before absorbing the rest with a sponge or towel.

Cove Dishwasher Filter is Clogged

A dishwasher’s filter screens out larger food particles and debris during draining to prevent them from clogging the drain pump or hose. However, without regular cleanings, the filter itself can become clogged and dishwasher water won’t drain through the filter, leaving puddles behind. Cleaning the filter at least once a month can prevent blockages. 

Dishwasher water won't drain

Clean Cove dishwasher filter with these simple steps:

  • Remove the bottom rack and spray arm.
  • Rotate the filter counterclockwise and lift straight up to remove.
  • Rinse the filter in warm, soapy water. Scrub stubborn stains with a soft brush, avoiding any abrasive materials. An old toothbrush is a perfect texture and size.
  • Replace the filter by pushing it down firmly while rotating it clockwise until secure.
  • Reinstall the bottom spray arm and rack.

Clogged or Kinked Drain Hose

A Cove dishwasher drain hose transports dirty dishwasher water to the sink or disposal drain. This light plastic hose is found under the sink, where stored items often push it against the wall, causing kinks that prevent draining. When you notice water not draining from dishwasher, inspect the hose for kinks, gently straightening them if possible. A damaged drain hose must be replaced.

Drain hose clogs from large food particles or debris can also prevent water from draining. If you suspect a clog, disconnect the hose from the drain or disposal and carefully remove any visible blockages. The hose may need to be disconnected from the dishwasher if the clog isn’t initially reachable.

Garbage Disposal or Air Gap Needs Clearing

Sometimes, draining problems aren’t due to a dishwasher clog but a blockage in your garbage disposal or air gap. If you have either of these two features, they share a common drain with your dishwasher. When they become clogged with debris, it can block the shared drain, causing water to remain inside the dishwasher tub.

If you have a disposal, running it before starting the dishwasher can help clear the drain of any debris. For those kitchens with an air gap, regularly remove the cap and scoop away accumulated food or grime with a paper towel.

Blocked Dishwasher Drain Pump

The drain pump expels dirty water out of the dishwasher and into the drain hose. If it becomes blocked with debris, its impellers may break or be unable to rotate, preventing the pump from expelling water. Sometimes, blockages can be dissolved by pouring a mixture of baking soda and vinegar down the dishwasher drain. Allow the mixture to sit for 10 minutes before flushing the drain with hot water.

If you still notice your Cove dishwasher not draining, the pump’s impellers should be inspected. Consult your user manual to determine how to access the pump on your model dishwasher. If the impellers are broken, the pump may require professional replacement.

Cove Dishwasher Pressure Sensor is Clogged

If you still find your Cove dishwasher not draining after assessing for the above blockages, it’s possible that the pressure sensor is clogged. This component regulates how much water enters the dishwasher from your home supply. Once an adequate amount of water is reached, the pressure sensor signals the internal control board to shut the water inlet valve.

The pressure sensor is located in a small tube that connects to the dishwasher’s water heater. If the sensor is covered with debris it may not operate correctly. This can cause the dishwasher to overfill and not drain sufficiently. Given its location within the dishwasher, a professional service can best assess, clean, or replace the pressure sensor.
