The 4E error (also shown as 4C or 1E on some models) on Samsung washers indicates a water inlet issue, typically meaning the machine isn’t detecting enough water filling the drum within the expected time. This is a common, often DIY-fixable problem caused by supply disruptions or blockages.
Verify Water Supply Basics
Ensure both hot and cold water faucets are fully turned on and provide strong flow—test by disconnecting hoses and running water into a bucket. Straighten any kinked inlet hoses at the back and confirm secure connections to prevent leaks or restrictions. Low household pressure (below 20 psi) triggers this; contact your utility if needed.
Unplug the washer for 5-10 minutes to reset, then restart a cycle. This clears temporary glitches in 20-30% of cases.
Clean Inlet Filters and Screens
Debris is the top culprit. Turn off water supply, disconnect hoses from washer back (have a towel ready for drips). At the valve inlets, pull out mesh screens with pliers or fingers; rinse under tap or brush gently until clean—no soap needed. Reattach firmly, turn water on slowly to check for leaks, then test fill.
Repeat at faucet ends if screens are there. Clean every 3-6 months preventively.
Check Hoses for Blockages
Inspect hoses for internal clogs: detach, pour water through (or use a wire to probe gently), and shake out sediment. In cold weather, thaw frozen lines with a hairdryer. Replace cracked hoses (under $20 at hardware stores).
For front-loaders, confirm hot/cold hoses aren’t swapped—cold to left/blue inlet, hot to right/red.
Test Water Inlet Valve
If basics fail, the solenoid valve (rear, top-right) may be faulty. With power off, hoses detached, and multimeter (optional), check for 1000-2000 ohms resistance across coils. Listen for clicking during fill attempt—if silent, replace valve (model-specific, $30-100; YouTube guides help). Rarely, pressure switch hoses inside need unclogging via top panel.
Quick Diagnostic Steps
| Issue | Check | Fix Summary |
|---|---|---|
| Faucets/Hoses | Flow, kinks | Open fully, straighten/replace |
| Screens | Debris buildup | Rinse/pull out, clean twice yearly |
| Pressure | Bucket test | Call plumber if weak |
| Valve | Clicking/ohms | Test or replace solenoid |
| Reset | Power cycle | Unplug 5+ mins, retry |
Run an empty Rinse+Spin after fixes. If persistent on both hot/cold, suspect wiring or board—seek Samsung service with model number. Regular maintenance avoids 90% recurrences.
