Fagor Dishwasher Error F4

What is the situation with the problem of error code F4 affecting your Fagor dishwasher?

Hello hello! If you have the error code F4 on your Fagor dishwasher, it's because you have an overflow alert on your appliance. But you don't have much to worry about, the truth is that if you have the right tools and spare parts, this problem can be very easy to solve. Let's see!

The F4 error code indicates that there is a water overflow problem in the dishwasher, meaning that the water level inside the appliance is too high and can cause a leak or malfunction. This can be due to several reasons, but one of the most common is that the sensors, switches, or floats that detect the water level are defective and do not send the correct signal to the electronic board. In that case, you may need to replace them with new ones.

To fully understand what may be happening with your dishwasher and why this error code F4 has appeared, you need to know the possible causes:

• Excessive detergent: Using too much detergent can generate excessive foam, which can cause an overflow and trigger the F4 error code.
• Clogged or damaged filter: The drain pump filter may be clogged with food residue or dirt, preventing proper water drainage. It may also be damaged because bones with sharp points or fish bones could tear the filter and damage it.
• Clogged or damaged drain hose: The drain hose may be blocked by an object or have some damage that hinders water evacuation.
• Failure in the drain pump: If the drain pump does not work correctly, the water cannot be properly evacuated from the dishwasher.
• Failure in the water level sensor: A failure in this sensor can cause the dishwasher to not detect the proper water level and continue to fill up, resulting in an overflow and an F4 error code.
• Failure in the float switch: The float switch, also known as a pressure switch, is responsible for detecting the water level and sending a signal to the dishwasher to stop filling. If this switch fails, the dishwasher could continue to fill up and overflow.
• Issues with the internal wiring of the dishwasher: A failure in the wiring that connects the different components of the dishwasher can affect the operation of the drain pump or the water level sensor.

These would be all the probable causes for which the error code F4 can appear in our Fagor dishwashers. But let's now see how we can fix this problem.

How can the error code F4 be solved in Fagor dishwashers?

To fix the F4 error code on your Fagor dishwasher and be able to continue using it normally, you need to follow these steps we outline below:

1. Turn off and unplug the dishwasher to reset its sensors: This can be a simple and effective solution for many problems that arise in Fagor dishwashers. To do this, simply turn off the dishwasher from the power button and then unplug it from the electrical outlet. Now, please wait a few minutes and reconnect and turn it back on to check if the F4 error code has disappeared. This procedure resets the sensors and can eliminate occasional errors caused by a power supply failure.
2. Use less soap or appropriate detergent for your dishwasher: You may be using too much soap or detergent, causing excessive foam in your dishwasher and causing an overflow or triggering the sensors to detect an overflow.
3. Check the dishwasher filter and clean it if it is dirty or clogged: The filter is a part that retains food residues and other impurities that may enter or leave the dishwasher. If it is very dirty or clogged, it can prevent water from circulating correctly and cause an overflow. To clean it, carefully remove it and wash it with water, soap, a little vinegar, and a soft-bristle brush. Replace it back and make sure it fits properly. If you notice that the filter is broken or very deteriorated, then it would be best in this case to replace it with a new one that is compatible with your dishwasher model.
4. Check the drain pump of your Fagor dishwasher: If the filter has been affected or damaged, it is likely that the pump may also have been affected. That is why we recommend checking the drain pump of your dishwasher and making sure it is not blocked by food residue. Clean the pump, perform preventive maintenance on it, and make sure it is working properly.
5. Check the drain hose and make sure it is not bent, crushed, or clogged: The drain hose is responsible for evacuating dirty water from the dishwasher to your house's general drainage. If this hose is bent, crushed, or stuck, it can prevent water from flowing out properly and cause an overflow. To properly check it, you have to disconnect the dishwasher and carefully remove the hose. Check for any foreign objects or dirt that may obstruct it and remove them completely. Reconnect the hose and make sure it is not bent or crushed against the wall or the dishwasher itself.
6. Check the dishwasher leveler and adjust it if necessary: Some dishwasher models have this part. The leveler is a part that keeps the dishwasher level and stable. If it is unbalanced, it can cause water to accumulate on one side of the dishwasher and cause an overflow. To adjust it, use a bubble level and check if the dishwasher is level both horizontally and vertically. If it is not, turn the dishwasher's feet until it is.
7. Check the water level sensors and the switches or floats that control the water buoy: There is a level or buoy that when the dishwasher is filling with water, this component is responsible for activating a switch or sensor that stops the water. It is common for this switch to become damaged over time and not send the signal correctly. The good news is that this replacement is not very expensive and can be easily replaced.
8. Check the internal wiring of your Fagor dishwasher: It would not hurt to check all the internal wiring of your dishwasher. This is because rodents tend to eat the cables to sharpen their teeth or to exhaust your patience. We recommend checking this wiring and verifying that there are no cut, torn, bitten, or burned cables. If you find cables in poor condition, it would be best to repair them and check if the connections are good and free of sulfate.
9. If the problem persists, please review all the above-mentioned and follow the steps to the letter: It is possible that you have missed some detail or have not correctly performed one of the steps we have mentioned. We recommend that you read everything again but this time paying more attention to detail and repeat the steps carefully. It is important to check each of the steps we have indicated above to rule out any problems that may cause this error in your dishwasher.
10. Call a Fagor technical service and request a home visit for a more thorough review: If you have already tried all the above solutions and the F4 error code continues to appear, you can contact the official Fagor technical service and request a home visit. A professional and qualified technician can diagnose the problem accurately and fix your dishwasher safely.

In summary, the F4 error code indicates that there may be a water overflow problem in your Fagor dishwasher. This problem can be caused by various reasons, such as defective sensors, dirty filter, clogged drain hose, unbalanced leveler, internal wiring eaten by rodents, and/or a failing sensor. To fix it, you can follow the steps we have explained above and in detail. Good luck and happy washing!
