E2

Water Supply Error

Severity

High

If your Samsung Washing Machine is displaying the error code E2, the control board has detected a fault identified as "Water Supply Error". Understanding the root cause helps you avoid an unnecessary service call.

Owner's Summary

Your washer cannot get water in. Think of it like a garden hose with the tap turned off — something is blocking the water from reaching the machine. This is not an emergency, but the washer will not run until fixed.

Symptoms

Washer stops mid-cycle, door locked, water not filling, error E2 on display

Common Causes

Water supply hoses kinked or closed
Inlet valve filter screens clogged with sediment
Faulty water inlet valve
Low household water pressure

How to Fix

1 Check that both hot and cold water supply valves are fully open
2 Inspect inlet hoses for kinks or blockages
3 Remove and clean the inlet valve mesh screens
4 Test water pressure at the tap (should be 20-116 PSI)
5 Replace the water inlet valve if cleaning does not fix it

Tools You'll Need

Pliers Soft Brush Towels / Bucket Flashlight

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

The ECU monitors flow through the inlet valve solenoid. When the water level sensor fails to detect a rising drum level within the programmed time window, the control board triggers E2 and cuts power to the door latch relay to prevent flooding.

Is It Safe to Keep Using?

Safe to leave the appliance off. Do not force a cycle — continued attempts without water can overheat the motor. Address within a few days.

Technician's Pro Tip

Before ordering a new inlet valve, always clean the mesh screens first — 60% of E2 errors are caused by sediment buildup, not a failed valve. Takes 10 minutes and costs nothing.
