Answer to continue safely
Is it safe to keep using?
Maybe. If the cause is simply closed valves or clogged screens, the washer is safe once the supply issue is resolved. However, if the inlet valve has failed partially, running the machine could result in overheating (no cold water) or inadequate rinsing.
Can I reset the code?
Yes. Fix the water supply issue, then press Start/Pause or power cycle the washer. The 4E code will clear once the machine detects adequate water flow during the next fill attempt.
When to stop immediately?
Stop if you notice: Water is leaking from the fill hose connections or valves, You hear the inlet valve buzzing but no water enters the tub.
Symptoms You May Notice
Washer does not fill with water
The machine starts a cycle but the drum remains dry or only partially fills, and the cycle stalls.
4E or 4E1 displayed on panel
The control panel shows the water supply error code, halting the wash cycle.
Cycle takes unusually long to start
The washer attempts to fill for an extended period before eventually timing out and displaying the error.
Only cold or only hot water fills
One inlet valve works while the other is blocked, causing the washer to fill with the wrong temperature water.
Possible Causes
Closed or restricted water valves
The hot or cold supply valves behind the washer are not fully open, or mineral deposits inside the valve body restrict water flow below the minimum required by the washer.
DIY PossibleClogged inlet filter screens
The small mesh screens at the washer end of each fill hose trap sediment and mineral scale over time, progressively reducing water flow until the fill sensor cannot detect adequate water.
DIY PossibleFailed water inlet valve
The dual solenoid inlet valve inside the washer electrically opens to allow water in. One or both solenoid coils can burn out, preventing water from reaching the tub even with full supply pressure.
Requires ProfessionalSafe Checks You Can Do
-
1
Check supply valves
Locate the hot and cold water valves behind or beside the washer. Turn both fully counter-clockwise to ensure maximum flow. Run a nearby faucet to verify household water pressure is normal.
If you recently had plumbing work done, air in the lines can temporarily reduce flow.

2
Clean inlet filter screens
Turn off both water valves. Disconnect the fill hoses from the back of the washer. You will see small mesh screens inside the hose fittings — carefully remove them with needle-nose pliers, rinse under running water, and reinstall.
Have a towel ready — some water will drain from the hoses when disconnected.
Tools required -
3
Run a test cycle
Reconnect the hoses, fully open both valves, and start a quick wash cycle. Watch through the door (front-loader) or listen for water entering (top-loader) within the first 2 minutes.
If water enters slowly but eventually fills, the issue is low pressure rather than a failed valve.
When to Call a Professional
Contact a qualified technician if:
- Both supply valves are fully open and screens are clean but water still does not enter
- The inlet valve hums or buzzes without allowing water through
- Water pressure at the washer hose connections is below 20 psi when tested with a gauge
