Problems you may notice
• Washer stops mid-cycle and displays F4 error code
• No water entering the washing drum
• Water fills very slowly during wash cycle
• Error code appears during initial fill phase
• Cycle halts and cannot resume automatically
• Water may partially fill then stop
• Error message repeats on subsequent wash attempts
Possible Causes
• Water supply valves turned off or partially closed
• Kinked or pinched inlet hoses restricting water flow
• Inlet hose screens clogged with sediment or mineral deposits
• Low water pressure from home supply line
• Faulty water inlet valve not opening properly
• Damaged or disconnected inlet hose connections
• Water supply issue specific to your home's plumbing
• Inlet valve solenoid malfunction
• Washer door or lid not fully closed, triggering safety lockout
Precautionary measures
• Verify both hot and cold water supply valves behind the washer are fully open (turn counterclockwise)
• Check that the washer door or lid is completely closed and latched securely
• Inspect both inlet hoses for kinks, pinches, or bends that restrict water flow
• Look at the inlet hose connection points to ensure they are tight and not leaking
• Disconnect inlet hoses and check the screens inside the hose connectors for debris or sediment buildup; rinse screens if needed
• Test water pressure at your home's other faucets to confirm adequate supply
• Ensure you are using the correct amount of detergent as excessive suds can affect water detection
• Check that the washing load is balanced and not overstuffed
• Verify your home's circuit breaker is in the ON position for the washer outlet
• Perform a complete reset: turn off the circuit breaker for 60 seconds, then turn it back on and attempt a new wash cycle
• If the F4 error persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose potential inlet valve issues or internal sensor problems
