E01 indicates abnormal water supply in Sharp ES-FW70EW, ES-FW85SG, and ES-FW105SG from Singapore. In this family, it does not refer to the door.
Page 32 of the official ES-FW manual verifies the association. Confirm the full model reference before applying a table with a different meaning for E01.
Go through the water inlet
Check that the shutoff valve is open and that there is no interruption in the supply. See whether the hose is bent or pinched behind the machine. Having water at another faucet does not guarantee sufficient flow at the washing machine connection.
The manual for this family includes cleaning the inlet filter. Before servicing it, disconnect power and shut off the water; follow the indicated removal, cleaning, and reassembly steps and check the connections when the supply is restored. Do not permanently remove the screen or open the solenoid valve.
The pressure figures apply to the specific unit and should not be copied to other Sharp models. If E01 returns with the external supply and filter checked, request a fill-system diagnosis.
When reporting the alarm, include ES-FW and the rest of the model reference so that a door table from another platform is not consulted.
