Step-by-Step Fix

1

Check water supply valves

Locate the water supply valves behind your washing machine. Make sure both hot and cold valves are fully open — turn them counter-clockwise until they stop.

2

Inspect inlet hoses

Check both inlet hoses for any kinks, bends, or damage. Straighten any kinked hoses and ensure they have a smooth path from the wall to the machine.

3

Clean inlet filter screens

Turn off the water supply and disconnect the hoses. You'll find small mesh filter screens inside the hose connections. Remove them carefully and rinse under running water to clear any debris.

⚠️

Make sure to turn off water supply before disconnecting hoses to avoid flooding.
