All Samsung Dishwasher Error Codes: Full List and Meanings

Quick Answer

This page lists every documented Samsung dishwasher error code in one place. Samsung uses two-character codes.

Samsung dishwasher error codes: LC (leak/base pan moisture), OC (overfill), 4C (no water supply), SC/5C/SE (drain fault), OE (overflow), LE (motor locked), 9E (water level sensor), PC (pressure sensor), 3C (motor communication). LC is the most searched code and is frequently a false positive from condensation. Most codes clear with Start/Cancel held 3 seconds after the cause is fixed.

What Does the ERROR-CODES Code Mean?

This page lists every documented Samsung dishwasher error code in one place. Samsung uses two-character codes. Some faults like drain errors have three names across model generations: SC (current), 5C (mid-generation), and SE (early). All three mean the same thing.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Base pan moisture or condensation (LC)40%
Drain filter or pump mesh blocked (SC/5C/SE)24%
Water supply valve closed or inlet screens clogged (4C)14%
Motor, sensor, or board failure (LE/3C/9E/PC)12%
Float switch stuck or inlet valve stuck open (OC/OE)10%

Symptoms You May Notice

  • Two-character code visible on display
  • Machine stops mid-cycle
  • Machine refuses to start
  • All lights flashing (no numeric display models)

Can you reset a Samsung dishwasher to clear the ERROR-CODES code?

Hold Start/Cancel for 3 seconds to clear most error codes after the cause is fixed. LC requires draining the base pan by tilting the unit 45 degrees for 20 minutes.

1

Identify the code on the display

Identify the code on the display. Match it to the table: LC (leak sensor), OC or OE (overfill), 4C (no water), SC/5C/SE (drain fault), LE (motor locked), 9E or PC (sensor fault), 3C (motor communication).

2

Perform a soft reset

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

How many error codes does a Samsung dishwasher have?
Samsung dishwashers have approximately 11 documented error codes: LC, OC, OE, 4C, SC, 5C, SE, LE, 9E, PC, and 3C. SC, 5C, and SE are the same fault across different model generations.
What does it mean when a Samsung dishwasher shows an error code and won't start?
The machine detected a fault and is preventing operation as a safety measure. Identify the code, follow the specific repair guide, fix the underlying cause, then hold Start/Cancel for 3 seconds to clear the code.
Can Samsung dishwasher error codes appear randomly without a real fault?
Yes. LC is the most common false-positive code, triggered by condensation rather than a real leak. 4C can also appear when water pressure is temporarily low. If a code appears once and does not return after a reset, it was likely a transient event.
