Troubleshoot error code "F7" in Fagor Dishwasher

How to fix F7 error in Fagor Dishwasher

Error: Temperature failure.
Description: The dishwasher displays error code F7.
Causes: The causes can vary, such as problems with the heating resistance, the resistance sensor, the NTC probe, electrical connections, wiring, or a burnt component on the electronic board.
Solution: Remove the side panels of the dishwasher and follow the steps below:

Step 1: Remove side panels of the dishwasher

To access the components that may be causing the F7 error, you need to remove the side panels of the dishwasher. The first thing you need to do is to disconnect the dishwasher from the electrical outlet to avoid accidents. Then, remove the screws that hold the side panels and carefully remove them.

Step 2: Locate heating resistance

Once you have access to the internal components of the dishwasher, locate the heating resistance. This resistance is responsible for heating the water used to wash the dishes and utensils. In some dishwasher models, the resistance may be located at the bottom, while in others, it may be at the back.

Step 3: Check sensor or switch on the same resistance

Once you have located the heating resistance, check if there is any sensor or switch connected to it. If there is, check if it is working correctly or if it is damaged. In some cases, it may be necessary to replace this sensor or switch to solve the problem of the F7 error code.

Step 4: Verify NTC probe

The NTC probe is a sensor used to measure the temperature of the water in the dishwasher. If this probe is damaged or not functioning correctly, it may be the cause of the F7 error code. Verify that the NTC probe is connected correctly, and there is no damage to the cables.

Step 5: Check arrival of voltages, connections, and wiring

If, after checking the heating resistance, the sensor or switch connected to it, and the NTC probe, the problem persists, it is essential to check the arrival of voltages to the different components, as well as the connections and wiring. If there is any loose cable or defective connection, it may be causing the temperature failure.

Step 6: Check electronic board on the front panel of the dishwasher

Finally, if after verifying all the above components, the problem persists, it is possible that the electronic board on the front panel of the dishwasher has a burnt component. To check this, it is necessary to remove the front panel and visually inspect the electronic components on the board. If you find any burnt or damaged component, it will be necessary to replace the entire electronic board.

It is important to note that some of these steps may require specific technical knowledge, so if you are unsure how to carry out any of them, it is recommended that you seek help from a specialized technician.

The F7 error code in a Fagor dishwasher indicates a temperature failure, which can be caused by problems with the heating resistance, the sensor or switch connected to it, the NTC probe, electrical connections, wiring, or a burnt component on the electronic board. To solve this problem, it is necessary to remove the side panels of the dishwasher and carry out a series of steps that include verifying the different components mentioned above. If the problem persists after following these steps, it is recommended to seek help from a specialized technician to avoid possible damage or accidents.
