Washer-dryer emits loud humming but does not fill with water at the start of cycle

Safety first: Unplug the appliance and close the water tap before removing hoses.

Step-by-step checks:

• 1. Clean inlet filters: Remove the inlet hose and clean the mesh filters in the valve.
• 2. Check water pressure: Confirm strong flow from the tap.
• 3. Test valve: If the valve hums but no water flows despite good pressure and clean filters, the internal plunger may be stuck or the coil weak. Replace the water inlet valve.
