We’re going to dive into the most common causes of a Cove dishwasher not cleaning dishes properly and how to fix or prevent this problem. By the end, you’ll have sparkling clean dishes after every cycle!
Why Is My Cove Dishwasher Not Cleaning Well?
Whether your clean dishes are coming out with white spots or bits of stuck-on food, we can help. Watch out for these known causes of poor dishwasher cleaning performance.
1. Overcrowded Dishwasher
One common cause of a Cove dishwasher not cleaning dishes is simply trying to fit too many dishes into the machine. Although it might feel like a game of Tetris, it’s essential to avoid overcrowding your dishwasher. If the water can’t reach all the surfaces, those pesky bits of food will stubbornly cling to your plates and silverware.
To prevent this, ensure you’re loading your dishes properly, giving them enough space for water to circulate. Check your Cove dishwasher manual for specific loading instructions, and don’t forget to remove any large food particles before loading.

2. Water Supply Problems
Another common reason for a Cove dishwasher not cleaning dishes is water supply problems. Without enough water, your machine won’t be able to clean your dishes efficiently.
First, check if the water supply valve is fully open. If it’s not, give it a twist, and you might just solve your problem. Next, inspect the water inlet valve and hoses for any signs of damage, kinks, or clogs. Replace them if needed, or call in a professional like Blue Sky Appliance Service to lend a hand.
3. Dishwasher Detergent and Dispenser Issues
A Cove dishwasher not cleaning dishes could also be due to detergent or dispenser issues. Make sure you’re using a high-quality detergent specifically designed for dishwashers. Also, check the detergent dispenser for any clogs or damage, as this could prevent the detergent from being released during the wash cycle.
If you’re experiencing a Cove dishwasher leaving white residue, it might be due to hard water. Using a rinse aid or water softener can help alleviate this issue.

4. Dishwasher Requires Cleaning
“How do you clean the filter on a Cove dishwasher?” you ask? Well, sometimes a Cove dishwasher not cleaning dishes is simply because the machine itself needs a good scrub. Over time, the dishwasher’s filter, spray arms, and other components can accumulate food particles, grease, and soap residue.
Start by cleaning the filter. Remove it from the dishwasher and rinse it under warm water. Use a soft brush to remove any debris. Check your Cove dishwasher manual for instructions on cleaning the spray arms and other components. Finally, run an empty cycle with a dishwasher cleaner to give the whole machine a thorough cleanse.
We hope these tips help you troubleshoot your Cove dishwasher not cleaning dishes issue. By addressing loading, water supply, detergent, and cleanliness issues, you’ll have your dishwasher working efficiently in no time.
