You have a dishwasher full of dishes that you do not want to wash by hand. Suddenly, the dishwasher says to “check water.” Now, what? Do not panic when you see this message or indicator, because it is possible to learn how to do it, and to resolve the issue.

Let’s find out how to check water when you see an error code on your dishwasher. 

Bosch Dishwasher 

Bosch is the dishwasher brand that is most commonly associated with the possibility of saying to check water. There is likely an easily identifiable solution to this issue.

Bosch dishwashers have the capability of displaying a number of error codes. There is, of course, also the possibility of experiencing an issue although the error code does not show on the dishwasher. Fortunately, an issue that requires you to check water is one of the error codes that will normally display for you.

A Bosch dishwasher is often high quality, but they are prone to asking owners to check water.

What is Error Code E04, and how do you resolve it? The error code displays when there is a water flow sensor error. The error code typically appears because of a clogged inlet valve or because of a clogged or blocked hose. One other issue is that there could be a software error.  

First, check for a software glitch or error. Unplug the dishwasher. Leave it unplugged for approximately 15 minutes. Check for clogs or bends in the inlet hose during that time. 

Plug the dishwasher back in and run a full cycle. Did performing these steps eliminate the error code E04? Did the error code remain or come back after this step? It is time to perform additional steps if the error code is still there or if it comes back again.  

Homeowners that have hard water in their home may experience an issue with calcification occurring or a buildup of minerals that block sprinklers or contribute to other error codes appearing on their Bosch dishwasher. 

Troubleshooting Error Codes

  • Step 1: Check the sprinkler. Is the sprinkler dirty? Remove the sprinkler and hold it under running water. 
  • Step 2: Check the holes. They could be dirty. Use a toothpick to clean the holes in the sprinkler. 
  • Step 3: Make sure that it is rinsed thoroughly
  • Step 4: Make sure that the holes are completely cleaned before you put the sprinkler back in place. 
  • If an E04 error code appears again, there is a possibility that you will need to replace the flow sensor. 

Do you have an E07 error code displayed on your Bosch dishwasher? The hole through which the dishwasher gets water into its system from the hopper becomes clogged or closes when there is an E07 error code. 

Resolve this issue by following a few simple steps. First, drain the water from your Bosch dishwasher. Next, remove the pallets, and remove the filter. Remove any food particles or debris from the filter. Finally, rinse the filter and put it back into the dishwasher. 

Error code E15 is another check water code that you may see on your Bosch dishwasher. A common reason that you may see this code is that there is excess water accumulated in the bottom of the dishwasher. The safety switch triggers when the excess water is present, leading to the error code display.  

Do you feel confident enough to check the cause of this error code, and to resolve this issue without calling the Bosch helpline number?  

First, tilt the Bosch dishwasher at a 45-degree angle to the left, which resets the E15 error code. Next, you need to remove the excess water from the tray. Dry the tray thoroughly and put it back into its normal position. These steps may resolve the issue, or you may find that you will see the same error code again in the future.  

Seeing repeated E15 error code messages means that you need to find the source of the leak. If you continue seeing the E15 error code, this situation requires an advanced diagnosis and troubleshooting process.

Are you confident in your ability to remove parts to perform tasks such as checking the water tank and the water leakage sensor? Many homeowners choose to consult their Bosch manual for the helpline number, or they prefer to call a professional Bosch repair technician. 

There are other error codes that may be related to a check water message, or that are the result of other issues with your Bosch dishwasher. Check the reason for any error codes, and promptly take steps to resolve the issue. Make sure that you contact a qualified repair technician or call the Bosch helpline if you cannot determine the reason for the check water error message.

Samsung Dishwashers 

Samsung dishwashers have the capability of displaying more than 20 error codes. How do you know what to do when you see a check water error code displayed on your dishwasher?  

You will likely never see the majority of error codes that may appear on a Samsung dishwasher. Some codes may be exclusive to the particular model of dishwasher.

Samsung dishwashers have so many options on the control panel that first-time users could be a little confused.

What happens if you do see an error code related to a check water indicator? How do you do it? Let’s find out right now. 

First, it is important to note that some Samsung dishwashers do not display an actual error code. These particular Samsung dishwasher models display blinking lights instead of error codes.

Samsung explains that when you see blinking lights on the dishwasher, it typically requires only a slight correction to resolve the error. The company stresses the importance of resolving any error code promptly to avoid the possibility that the issue will eventually impair your dishwasher. 

One of several codes may appear on your Samsung dishwasher if your machine has a leak. Your dishwasher may display an error code 5C, 5E, 0C, or 0E. These error codes display when there is a drain and overflow issue. Some machines may blink lights on “Heavy” or “Auto.” 

Follow these steps to try and resolve the error code.

  • Step 1: Check the drain hose.
  • Step 2: Make sure that the dishwasher hose is in the proper position
  • Step 3: Make sure that there are no twists or bends in the hose.
  • Step 4: Straighten the hose to undo any twists or kinks. 
  • Step 5: Make sure that the check valve is not stuck in the “off” position.

Run water for at least 30 seconds. Make sure that you verify the sink drain. If you discover that this is not the issue, then the problem may be with the plumbing in your home, and not with your Samsung dishwasher. 

Do you see an error code LE or LC? These errors indicate that there is moisture detected where it does not belong in your Samsung dishwasher. You may not notice the excess moisture, so do not assume that it is not there just because you cannot see it. Let’s take a look at what to do if there is a visible leak after you see the error code. 

Is there a visible leak? If you see a leak, the first step is to turn the dishwasher off at the circuit breaker. Inspect the water supply hose for signs of moisture, loose connections, or damage. Signs of damage coming from the water supply hose indicate that you need to replace it. Once you purchase the replacement hose, follow the installation instructions, or call a qualified professional installer.

Another possible reason for the LE or LC error is an issue with the drain hose. Check it and tighten the connection if you discover it is not properly connected when you check for leaks.
