When a clothes washer is very slow filling on “cold wash” or “cold rinse”, the cold water filter is usually partially blocked. Removing the filter can allow debris to go into the water valve, possibly causing flooding. This method cleans the filter by back-flushing and prevents unwanted particles from entering the valve.
Turn the cold water off to the inlet hose.
Turn the machine on for two seconds, then off (use "cold wash")
Remove cold inlet hose from faucet.
Place end of hose into clean bucket.
Locate small hose connected to fill valve.
Clamp this small hose to prevent water from entering washer.
Turn washing machine on and observe particles washing into the bucket.
