Aiman, The F24 error code indicates a water temperature sensor reading that is out of range on this model of washer. The first step to troubleshooting this code is to unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU).Check the wiring connections between the temperature sensor and the control board. To access the temperature sensor at the back of the tub, you will need to unplug the washer and remove the back panel.If you can give us the model number I could try to find the right diagram and manual for you. Hope this helps, good luck.
