What Does the 800140 Code on Cove Dishwasher Mean?
Oh, your Cove dishwasher has finally tossed the error code 800140? Great; you are not alone. The little blinking light of error staring at you from your dishwasher appears daunting. Still, all that is trying to tell you that something is amiss, merely an SOS your appliance is trying to send your way.
We’re here to break it down for you-what it means, what can cause it, and more importantly, how you can fix it without sweating. Spoiler alert: some of the solutions are easier than you think!
What is an 800140 Error Code?
Error code 800140 on a Cove dishwasher commonly means that the drain is the problem. What does that mean? Your dishwasher basically has some issues removing water from inside the appliance.
That could be from blockage issues in the draining system, defective pumps, or even installation gone wrong. The issue is very common, though frustrating, the fix is sometimes easier than one may imagine.
Here’s what could possibly fire this code up: Clogged drain filter: The filter gets blocked with waste, food particles, or grease, which stops the water from flowing correctly.
Kinked or clogged drain hose: A bent or plugged drain hose will prevent water from draining out of your appliance.
Pump malfunction: The failure to operate the drain pump properly will prevent the water from draining as expected.
Poor installation: Sometimes poor installation, such as installing the drain hose too high, can be a source of drainage problems.
Now that we’ve narrowed down the usual suspects, it’s time to roll up your sleeves and get to the fixes.

How to Fix Cove Dishwasher Code 800140
Before calling in the reinforcements, aka a tech visit, try these easy troubleshooting steps. You might be surprised at how fast you can get your dishwasher back in action!
1. Check the Drain Filter
First, check the drain filter. Cove dishwashers have a filter that catches the bits of leftover food. Over time, this will block.
Here’s how to clean it: Open your dishwasher and locate the filter-it is usually located at the bottom. Twist and pull it out. Rinse well under warm water. Use a soft brush if needed to scrub off stubborn bits. Put the filter back in its spot.
2. Check the Drain Hose
Have a look at the drain hose of the dishwasher, the tube that carries the water out. Is it bent, kinked, or clogged?
Here’s what to do: Unplug the hose and check if something blocks it or whether it is clogged; in that case, rinse it. Make sure the hose is positioned correctly-no sharp bends or loops. Double-check the hose isn’t too high. If it is, this may lead to some draining problems-usually, no more than 18 inches above the floor.
3. Check the Drain Pump
If your issue wasn’t sorted out after cleaning the filter and the hose, then it’s time to look at the drain pump for trouble. Here is a simple test: Run a rinse cycle. Listen to it. Does the pump seem to be making weird noises? If the pump makes some struggling sounds or none at all, then it may need to be repaired or replaced. This is now the right time to seek the services of a professional.
4. Installation Problems
If you have just installed your dishwasher, then you should make sure everything was properly installed. Go through the manual again to ensure that none of the installation steps were missed or done incorrectly.
5. Reset the Dishwasher
Sometimes, a simple reset can clear the error code and get your dishwasher running again. Try this: Turn off the dishwasher, unplug it, and wait for about 10 minutes. Plug it back in and restart the machine. If the code reappears after resetting, it’s likely there’s a deeper issue requiring professional help.
When to Call a Professional
If all the above steps have been tried and the error code 800140 keeps staring at you, then there’s no reason to panic. This could only mean that a mechanical part like the drain pump has gone bad and needs replacement or repair. Contacting Cove customer support or a qualified technician is your best bet at this stage.
Pro Tip:
Have your dishwasher model number and date of purchase always ready when contacting support. It’ll make the process smooth and fast.
How to Avoid Drain Issues in the Future

Check the drain hose every few months to make sure it’s free of kinks or blockages. Schedule regular maintenance checks to keep all things in good condition.
