Error code EF10 on an AEG washing machine typically indicates a problem with water filling. Follow these steps to fix this issue:
1. Check if the water supply is turned on. If it's not, turn it on and check if the error persists.
2. Inspect the inlet hose for any kinks or obstructions that might be blocking the water flow. If you find any, straighten the hose or remove the blockage.
3. Clean the inlet filters. They might be clogged with debris and reducing water flow. You can usually find the filters at the end of the inlet hose.
4. If the problem persists after checking and correcting these issues, it might be a problem with the water inlet valve or the pressure sensor. In this case, it is recommended to contact a professional for further assistance.
