Samsung Dishwasher: error code

Professional Repair Guide

What is this symptom?

If your Samsung dishwasher displays an error code, it indicates a self-diagnosed fault such as water supply issues, leaks, drainage problems, or sensor failures. These alphanumeric codes vary by model and require careful interpretation to determine the underlying problem, which can range from simple clogs to motor malfunctions.

Urgency: Medium

Important Tips for Samsung Models

  • Error codes like 4C/4E indicate water supply issues; 5C/5E indicate drainage issues; LC/LE indicate leak detection. Codes like 1E/IE can relate to low water level or clogged filters. 3C series codes often point to pump/motor errors. These interpretations come from Samsung support and community repair documentation.

Possible Causes

Water supply error (not enough water or no water detected)

How to Identify: Error codes like 4C or 4E on display; dishwasher fails to fill with water or begins cycle with no water intake detected. Ensure water valve is open and hose not kinked.

Part: Water inlet system (valve, hose, pressure sensor)

Leak detection triggered

How to Identify: Codes like LC/LE appear, often alongside water in the base pan or visible moisture leaks around machine.

Part: Leak sensor, door gasket, water supply connections

Clogged or dirty filter causing circulation/non‑fill problems

How to Identify: Low water level codes such as 1E/IE along with poor fill or standing water after cycles.

Part: Fine filter assembly at bottom of dishwasher

Pump or motor malfunction

How to Identify: Codes like 3C and variants (3C1, 3C2, etc. often mean the wash pump motor is not operating within expected parameters.

Part: Wash pump/motor assembly and associated inverter PCB
