miele dishwasher error f13

What could this error code mean in Miele dishwashers?

Hello hello! When it comes to keeping our homes running smoothly, every appliance plays an important role. And Miele dishwashers are no exception to this contention, as they are known for their efficiency and durability; obviously, they are not the exception to the rule. However, as with any technology, problems can arise, and at Errors Codes Ultimate, we are here to help you discover what may be happening with your dishwasher.

One of the most common errors in these appliances is the error code f13, which indicates a water inlet failure in your dishwasher. An error that can undoubtedly be frustrating, but with the right knowledge, it is possible to solve it without too many complications.

This fault is a warning sign that indicates that something is not right with the water supply of your dishwasher. But to be able to solve it satisfactorily, you first need to know the causes that can cause it:

  • A closed shut-off valve: If the valve supplying water to the dishwasher is not fully open, the water flow will be insufficient.
  • Low water pressure: Water pressure lower than necessary, that is, less than 0.5 bar, can prevent the dishwasher from functioning correctly.
  • A clogged filter: A dirty filter can restrict the flow of water, preventing the dishwasher from filling properly.
  • A clogged or broken hose: If the water inlet hose is not in good condition or is clogged with dirt or sediment from the water itself, then the fault will occur in the dishwasher.
  • A fault in the water inlet valve: This valve may be clogged by the same sediments that come with the water, so it is necessary to perform maintenance on it or it already requires replacement.
  • A fault in the water level sensor: This sensor may be very dirty and in need of maintenance, causing a false positive error that prevents normal use of the dishwasher.
  • A fault in the electronic PCB: Finally, the electronic board of your dishwasher could also present faults in very rare and specific cases, but it could happen.

All these causes are related to faults in the water inlet of your dishwasher, but now let's see the solutions so you can fix this problem.

How could I find the definitive solution to the F13 error in Miele dishwashers?

We have prepared for you a list of possible solutions so you can fix this fault in your Miele dishwasher. Don't skip any of the steps we're about to outline for you:

  1. Turn off and disconnect the dishwasher from the power supply to rule out possible temporary errors: Before doing anything else with your dishwasher, it's best to start with the easiest and simplest step, which is to restart the appliance. To do this, you need to turn off the dishwasher completely and disconnect it from the power supply for about 15 minutes. This may help rule out temporary errors or false positives, as this procedure completely resets the system, including the dishwasher's sensors. Once the time has elapsed, reconnect the dishwasher and proceed with turning it on to check if the error has disappeared. If the problem persists, then please proceed with the following steps we will indicate below.
  2. Check the water shut-off valve that supplies your Miele dishwasher: Make sure the shut-off valve is fully open to allow adequate water flow to your dishwasher. Sometimes, a valve that is not fully open can interfere with the water pressure reaching the dishwasher, causing it to not function properly. Verify that you have the water supply active and check that the other faucets in your home are supplied with water correctly.
  3. Check the water pressure reaching your Miele dishwasher: Verify that the water pressure and/or flow rate are adequate for the operation of your Miele dishwasher. To check this, consult the manufacturer's manual; however, we can tell you in advance that if the water pressure is less than 0.5 bar, then the dishwasher has a problem with the water flow and will not be able to function correctly. If necessary, adjust the water pressure and check with a pressure gauge that it is adequate.
  4. Clean the filter of your Miele dishwasher and make sure it is in good condition: Locate the water inlet filter of your dishwasher and remove it for preventive maintenance. Clean it thoroughly with a soft-bristled brush, warm water, and a little vinegar to disinfect it. Do not use a brush with very hard bristles as you could damage the filter mesh. If you notice that the filter is broken, then replace it with a new one that is compatible with your Miele dishwasher model.
  5. Check the hoses of your Miele dishwasher, especially the water inlet hose: Ensure that this hose is not bent or crushed against the wall, the dishwasher itself, or the floor. Make sure the hose is in good condition to supply water to your dishwasher. If you notice any pronounced bends or a breakage in it, then you will have to make the necessary repairs to ensure adequate water flow to your dishwasher.
  6. Check the water inlet valve of your Miele dishwasher: It often happens that this valve gets clogged with the same sediments or minerals that come with the water supply, so you have to remove it from the dishwasher and clean it thoroughly with warm water and a little vinegar. Make sure to clean the hole where the water enters and exits the valve well. If you think the water inlet valve is not working properly, replace it with a new one that is compatible with your Miele dishwasher model.
  7. Check the water level sensor of your Miele dishwasher: If the sensor is not in good condition, it may send false positive errors to the electronic card, causing an error to appear on the screen of your dishwasher. Therefore, it would be convenient to perform preventive maintenance on this water sensor and check that it is in good working condition. If you notice that the sensor is not working properly, then replace it with a new one that is compatible with your dishwasher.
  8. Check the electronic PCB board of your Miele dishwasher: As a last resort, it could happen that a voltage mismatch or a short circuit could negatively affect the electronic PCB board of your dishwasher. So, as a last resort, proceed to visually inspect the board of your dishwasher. Look for signs of burns, flashes, burnt resistors, bulging or exploded capacitors, etc. If you have knowledge in electronics and have a multimeter, then you can check this board in a much deeper way.
  9. Carefully review all the previous steps and repeat them if necessary: Go over everything again and make sure you have followed all the steps we have outlined for you. Do not skip any of the steps mentioned in this guide and follow them all to the letter to ensure optimal repair of your dishwasher. If the problem persists, then it is time to leave the problem in the hands of Miele dishwasher experts.
  10. Contact Miele's technical support for a thorough and exhaustive inspection of your dishwasher: If none of the above solutions resolve the issue with your dishwasher, please contact Miele's technical support. Explain the problem with your dishwasher in detail, as they are experts in the field and will make a home visit to resolve this fault in record time.

In summary, the error code f13 is related to problems in the water inlet of your Miele dishwasher. But there's no need to panic, as the causes can be easily addressed. What could cause this fault are: a closed shut-off valve, hoses in poor condition, a clogged filter or valve, inadequate water pressure, a malfunctioning water level sensor, or a problematic electronic board. This fault is fixable, and to fix it, you just have to follow all the steps we have outlined in this little guide of tips.
