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

Error Code Explained

What Does the Samsung 4E Error Code Mean?

Root Causes

Common Causes of the Samsung 4E Error Code

• 1
  Water Supply Valve Turned Off

  The hot and/or cold water supply valves behind the washer have been partially or fully closed — commonly after maintenance or moving. Check both valves are fully open (turned counter-clockwise as far as possible).
• 2
  Kinked Inlet Hose

  One or both inlet hoses (hot/cold) have become kinked where they connect to the back of the machine or at the wall. Even partial kinking reduces flow below the required threshold.
• 3
  Clogged Inlet Screen Filters

  Where the hoses connect to the back of the washer, small mesh screens prevent debris from entering the inlet valve. These screens can clog with mineral sediment, rust, or debris, severely restricting flow.
• 4
  Low Water Pressure

  Samsung washers require a minimum of 14.5 PSI water pressure. In homes with low municipal pressure, or during high-demand periods, pressure may drop below this threshold and trigger 4E.
• 5
  Failed Water Inlet Valve

  The solenoid inlet valve (typically dual-solenoid for hot and cold) can fail with a burned solenoid coil, preventing it from opening. This requires valve replacement.

Step-by-Step Guide

How to Troubleshoot the 4E Error Code

1. 1
   Check the supply valves

   Turn both the hot and cold water supply valves (behind the washer) fully counter-clockwise. Many 4E errors are resolved by simply opening a valve that was closed during a previous service call or move.
2. 2
   Straighten the inlet hoses

   Pull the washer away from the wall slightly and inspect both inlet hoses. Straighten any kinks. The hoses should have a smooth arc from the wall to the machine without tight bends.
3. 3
   Clean the inlet screen filters

   Turn off the water supply and disconnect one hose at the back of the machine. Look inside the connection port — you will see a small mesh screen. Use needle-nose pliers to carefully pull the screen out. Rinse under running water and reinstall. Repeat for the other port.
4. 4
   Check water pressure

   Turn on a nearby cold water tap fully. If the flow seems low, your household pressure may be the issue. Try running the washer when the pressure is highest (early morning, before peak usage hours).

FAQ

Frequently Asked Questions — Samsung 4E

• What is the difference between Samsung 4E and 4C?
  4E and 4C are the same fault. Samsung updated their display format in newer models — 4E appears on older machines, 4C on recent ones. The diagnosis and repair are identical.
• My Samsung washer shows 4E only on hot water cycles — what does that mean?
  If 4E only appears on hot wash cycles, only the hot water supply is restricted. Check that the hot water valve is open and that the hot water inlet screen is not clogged.
• Can cold weather cause Samsung washer 4E?
  Yes — in very cold weather, water supply pipes can freeze, cutting water supply to the washer. If 4E appears suddenly in winter, check whether other water fixtures in the house are also flowing normally.
