Diagnosis
Slow fill points to low water pressure or clogged inlet screens. This model uses pressure sensors to determine water level, so any restriction messes with it.
How to Fix It
Turn off the water supply valves at the wall. Disconnect the fill hoses from the back of the washer. Check the small mesh screens inside the water valve inlets on the machine—clean them with a toothbrush or rinse under water. Reconnect hoses, turn water back on slowly, and test.
If That Didn't Work
Your home's water pressure might be too low (should be at least 20 psi). Or, the water inlet valve could be sticking and need replacement.
Heads Up
Always use the supplied hoses or certified replacements. Kinked or old hoses can restrict flow and cause fill problems.
