What Does Error 4E Mean?

The Samsung Dishwasher error 4E indicates a water supply issue, where the appliance is unable to fill with water due to a closed, frozen, or clogged water supply valve. This error typically triggers a flashing display and can halt the dishwasher mid-cycle as it fails to receive sufficient water.

Common Symptoms:

  • Dishwasher displays ‘4E’ and may not start or will stop mid‑cycle due to lack of water supply.
  • No water filling in the dishwasher tub within the expected time.

Possible Causes

  • Water supply valve is closed, frozen, or clogged (high)
  • Water supply hose frozen, bent, or blocked (high)
  • Control board or internal electronic issue preventing water supply detection (medium)

How to Fix Error 4E

DIY Fix Check and ensure water supply and hose condition

  1. Verify the dishwasher’s water supply valve is fully open.
  2. Inspect the water supply hose for kinks, bends, or blockages and straighten if necessary.
  3. If the hose is frozen, warm it gently to restore flow (avoid burns).
  4. Check the inlet filter at the valve connection and clean away foreign material.

Technician Only Service internal components if basic checks fail

  1. Test and, if necessary, replace the water inlet valve if it is defective or clogged internally.
  2. Inspect the control board and electrical connections associated with the water supply detection circuit.
  3. Test water pressure at the dishwasher connection to confirm adequate supply (typically >20 PSI / ~1.4 bar).

Parts needed: Water inlet valve, Control board, Water supply hose

🛑 When to Call a Pro:
  • After basic water supply and hose/filter checks, if the 4E code persists.
  • If water pressure is confirmed adequate but the dishwasher still does not fill.
  • If internal diagnostics suggest an electronic control issue.
