Troubleshooting Your Cove Dishwasher Not Cleaning Dishes

In this Article


If your trusty Cove dishwasher has decided to take an unexpected vacation and your dishes aren’t coming out as clean as they used to, don’t fret. We’re here to help. We’ll delve into the common causes for your Cove dishwasher not cleaning dishes and provide some handy DIY solutions.

Why Is My Cove Dishwasher Not Cleaning Dishes?

We’ll explore several issues that could lead to your Cove dishwasher not doing its cleaning job well. For each issue, we’ll provide steps to help you fix or prevent your Cove dishwasher not cleaning dishes.

Insufficient Water Supply

A dishwasher that’s not filling up with enough water can lead to poorly cleaned dishes. The usual suspects are a stuck float switch or a malfunctioning water inlet valve.

  • Check the float switch for debris and clean as needed.
  • If the float switch is damaged, replace it.
  • If the water inlet valve is faulty, you’ll need to install a new one.
  • Also, make sure the water is turned on at the source and the hoses aren’t clogged or leaking.

Clogged or Dirty Spray Arm

Why is my dishwasher not cleaning my dishes all the way? Spray arms blocked with food particles or mineral buildup can prevent water from reaching your dishes, resulting in them not being properly cleaned.

  • Remove the spray arms and soak them in warm, soapy water.
  • Use a soft brush or toothpick to clean out the spray holes.
  • If they are damaged, consider replacing them.

Dirty or Clogged Filter

If your Cove dishwasher’s filter is clogged, it might not be able to effectively trap food particles, leading to less-than-clean dishes and your dishwasher not draining properly. How do I clean the filter on my Cove dishwasher?

  • Inspect and remove the filter, usually found at the bottom of your dishwasher.
  • Rinse it under running water and gently scrub it with a soft brush.
  • Replace it if you spot any damage.

Incorrect Dishwasher Settings

Using the wrong settings for the type of dishes you’re washing can also lead to your Cove dishwasher leaving dishes dirty.

  • Always ensure you’re using the right wash cycle for your load. Heavily soiled dishes may need a more intensive wash cycle, while lightly soiled dishes can use a normal or eco cycle.
  • Use the heat-dry or sanitize options for a thorough clean. These settings increase the temperature, which can help to better clean and dry your dishes.
  • Don’t forget to use a rinse aid. This helps to prevent spots and enhances drying.
  • Always consult your dishwasher’s user manual for specifics on each setting and how to best utilize them for different types of dishes and loads.

Detergent Issues

If your detergent dispenser is faulty, the soap might not be properly released into your dishwasher, leading to ineffective cleaning. Also, if you’re using a cheaper detergent, it can sometimes leave residue on dishes.

  • Check if the dispenser is jammed by dishes or silverware, and re-arrange your dishes if needed.
  • If the dispenser mechanism is broken, it will need to be fixed.
  • Make sure you’re buying quality dishwasher detergent and not cheap powder options.

Overloading the Dishwasher

Overloading can block the spray arms and water flow in your Cove dishwasher, leading to improperly cleaned dishes.

  • Ensure to leave enough space between items for water and detergent to circulate.
  • Resist the temptation to overload your dishwasher for the sake of cleaner dishes.

Water Isn’t Hot Enough

If your dishwasher isn’t heating up enough, it might not be able to effectively clean your dishes.

  • Check the heating element and replace it if faulty.
  • Also, ensure your home’s water heater settings are at least 120°F.
