Samsung Washer Error Code 4E — What It Means & How to Fix It

What Does This Error Mean?

The 4E error means your Samsung washer is not getting enough water. The machine tried to fill but didn't detect enough water coming in. This is usually caused by a water supply problem — not a broken washer.

Affected Models

WF45R6100AW
WF50R8500AV
WF45T6000AW
WF42H5000AW
Most Samsung front-load and top-load washers

Common Causes

Water supply faucets behind the washer are turned off or not fully open
Kinked or bent water inlet hoses
Clogged inlet hose filter screens
Faulty water inlet valve inside the washer
Low household water pressure

How to Fix It

Check that both hot and cold water faucets behind the washer are fully open.

These are the knobs or lever handles on the wall where the hoses connect.
Inspect the water inlet hoses for kinks or bends.

Straighten any kinks. Replace hoses that are severely bent or damaged.
Clean the inlet hose filter screens.

Turn off the water. Unscrew the hoses from the back of the washer. Pull out the small mesh screens with pliers and rinse them clean.
Press the Start/Pause button to restart the wash cycle.
If the error returns, the water inlet valve may need replacement.

This is an internal part — a technician should handle it.

When to Call a Professional

If you've checked the hoses and faucets and the error won't go away, the water inlet valve may be faulty. A technician can test and replace it. Expect repair costs of $120–$250 including parts and labor.

Frequently Asked Questions

What does 4E mean on a Samsung washer?

It means the washer is not receiving enough water. The machine cannot fill properly. It's almost always a water supply issue, not a broken washer.

Can I fix the 4E error myself?

Yes, most of the time. Check that the water faucets are on and the hoses aren't kinked. Cleaning the filter screens usually solves it. You only need a technician if the inlet valve is faulty.

Why does my Samsung washer show 4E in winter?

In very cold weather, the water supply lines can partially freeze. This reduces water flow to the washer. Make sure your laundry area stays above freezing. You can also run warm water at a nearby sink before starting the washer.
