Samsung Washer 4E Error — Water Supply Fix

What Does This Error Mean?

Samsung washer 4E error means the machine cannot fill with water. Check that the water tap is fully open, inspect the inlet hoses for kinks, and clean the mesh filters on the inlet valve.

Affected Models

Samsung Front Load Washer
Samsung Top Load Washer
Samsung AddWash Washer
Samsung EcoBubble Washer
Samsung QuickDrive Washer

Common Causes

Water tap not fully open or turned off
Kinked or crushed inlet hose
Blocked mesh filter on the inlet valve
Low water pressure from household supply
Faulty water inlet valve solenoid

How to Fix It

Check the water tap.

Locate the cold water tap behind the machine. Turn it fully counter-clockwise to open. A partially open tap causes low flow that triggers 4E.
Check the inlet hose for kinks.

Pull the machine slightly away from the wall and inspect the inlet hose. Straighten any bends or kinks. Also check the hose has not been crushed against the wall.
Clean the mesh filters.

Turn off the tap and unscrew the inlet hose from the back of the machine. Inside the connection port there is a small mesh filter. Remove it with pliers, rinse under running water, and refit. These filters block gradually over years of use.
Check household water pressure.

Samsung washers require a minimum water pressure of 0.5 bar. If other taps in the house also have weak flow, the household supply pressure may be too low — contact your water supplier.

When to Call a Professional

If the tap is open, hoses are straight, and mesh filters are clean but 4E persists, the water inlet valve solenoid has failed and needs replacement.
