Problem: Cold water inlet error – issue with cold water supply

How to Fix 4c Error

This is an error with the cold water supply. First, ensure the cold water faucet connected to the washer is turned on fully.
Check the cold water inlet hose for any kinks or twists that could block water flow.
Turn off the water, disconnect the hose from the back of the washer, and check the small filter screen inside the inlet port for debris. Clean it if necessary.
If the above steps don’t work, the cold water inlet valve has failed. Unplug the washer, replace the valve assembly, and reconnect the hoses and wiring.
