Samsung Washer 4E Error Code: Water Supply Fault (Top Load)
Quick Answer
4E and 4C are the same fault on different form factors. 4E fires on top-load models when fill pressure is not detected within 60 seconds.
In my fifteen years of fixing Samsungs, I usually see this code after a homeowner moves the machine or during the first cold snap of winter. It's essentially the washer saying it's thirsty but nothing's coming through the straw. While it often points to a failed inlet valve, I always check for kinked hoses or frozen pipes first before I start pulling the back panel off.

What Does the 4E Code Mean?
Think of the 4E code as a timeout. Your washer opens the internal valves and waits for the pressure sensor to tell it the tub's filling. If that signal doesn't arrive within a minute, the logic board shuts everything down to prevent the pump from running dry or the solenoids from overheating. It's a protective measure, not just a random error.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Inlet valve screens clogged with mineral deposits40%
Supply valves not fully open24%
Kinked or pinched fill hoses22%
Inlet valve solenoid failed14%
Symptoms You May Notice
Machine starts the cycle, you hear a click from the valve, but the drum stays completely dry for about a minute before 4E shows up and everything stops.
The error fires within the first 60 seconds of any wash cycle, doesn't matter what setting you pick.
Clothes come out totally dry after a 'completed' wash, or just faintly damp from humidity that was already in the fabric.
You can hear the solenoid clicking but there's zero sound of water actually rushing in.
Can you reset a Samsung washer to clear the 4E code?
Once you've addressed the cause, power the washer off at the panel and unplug it from the wall for a full 60 seconds. Then plug it back in and kick off a Rinse and Spin cycle. That forces a fresh fill request and gives the sensor a chance to confirm water's actually moving. If 4E comes right back, the underlying problem isn't fixed yet. Don't just keep resetting and hoping, you'll end up running the pump dry.
Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Replacement Parts
If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.
What's the difference between 4E and 4C on Samsung washers?
Same fault, different display depending on the model generation. 4E shows up on older top-loaders and some front-loaders, 4C is Samsung's newer format for the exact same water supply error. In the field the repair is identical, you're checking supply valves, screens, and inlet valve solenoids either way. The part numbers can differ between top-load and front-load models though, so make sure you've got the right valve for your specific unit before you order anything.
Can low water pressure cause 4E without any blockage?
Absolutely, and I see this more than you'd think. Older homes with galvanized pipes, apartments with shared supply lines, or anyone running the dishwasher and a shower at the same time can drop pressure low enough to trigger this. Samsung's fill sensor is pretty unforgiving below about 15 psi. If your screens are clean and the valve tests good on the multimeter, grab a cheap water pressure gauge from the hardware store and check what's actually coming out of that laundry faucet. Under 20 psi and you might need a plumber to look at your main pressure regulator.
How much does it cost to fix a Samsung 4E error?
Depends entirely on the cause. Kinked hose or half-closed valve? Free. Cleaning the inlet screens? Also free. A new inlet valve assembly runs about $35-60 for OEM. If you're calling a tech out, add $80-150 in labor on top of that. I replaced three of these valves last Tuesday alone, so it's a very common and very fixable repair. Most people who are reasonably handy can do it in under an hour.
Can I run my Samsung washer with the 4E code showing?
No, and don't try. The machine already stopped itself to protect the motor and pump. If you somehow force a cycle with no water, you'll burn out the pump within a few minutes and turn a $50 fix into a $200+ repair. Just find the cause, fix it, and reset. It won't take long.
How do I tell if it's the screens or the valve itself that's the problem?
Pull the screens first. They're free to clean and take about 5 minutes. If the screens look totally clean, barely any buildup, move on to testing the valve solenoids with a multimeter. A bad solenoid reads open circuit, OL on the display, or way outside the 600-1000 ohm range. Good screens plus bad solenoid equals valve replacement. Good screens plus good solenoid means look at your water pressure or trace the wiring back toward the control board.
Does Samsung warranty cover the 4E error repair?
The inlet valve is a mechanical wear part, so Samsung's standard 1-year limited warranty covers it if the machine's still new. After that you're on your own. Some extended warranty programs through big-box retailers do cover water supply component failures though, so it's worth a call if your machine's under 3-4 years old and you bought a plan. If not, just fix it yourself. The valve's not expensive and the repair's pretty straightforward even if you've never done appliance work before.
