Samsung Washing Machine Error Codes Explained: The Ultimate 2026 Repair Guide
Samsung error codes look scary, but in 2026, most of these issues can be resolved at home without spending a penny on a technician. Whether you have a classic front-load or the latest AI-powered Bespoke washer, these codes are the machine's way of telling you exactly what’s wrong.
As an appliance repair specialist with over a decade of experience, I’ve decoded thousands of these signals. This guide provides the most comprehensive breakdown of every Samsung error code, updated with 2026 tech insights, safety protocols, and cost-effective fixes.

Essential Tools for DIY Repair
Before we dive into the code, ensure you have these tools ready. Using the right tool prevents damage to your expensive appliance.
- Phillips & Flathead Screwdrivers: For removing the back panel and top cover.
- Multimeter: Essential for checking 2026 digital sensors and motor continuity.
- Small Soft Brush: For cleaning delicate inlet mesh filters.
- Bucket and Towels: Samsung washers hold up to 2 liters of emergency water in the drain pump area.
- Pliers: To tighten or loosen hose clamps safely.
1. 4C / 4E: Water Supply Failure
Symptoms: The cycle starts, you hear a hum, but no water enters the drum. After 10 minutes, the 4C code appears.
How to Fix:
- Safety First: Unplug the machine.
- Check Taps: Ensure both hot and cold taps are fully turned on.
- Inspect Hoses: Look for kinks. Modern 2026 No-Burst hoses can sometimes collapse internally.
- Clean Inlet Filters: Unscrew the hoses from the back of the washer. Use a brush to clean the small mesh filters.
Expert Tip: If you have high water pressure but the code remains, your water inlet valve solenoid may have burnt out.
2. 5C / 5E / nd: Drainage Blockage
Symptoms: The washer stops before the spin cycle, and the drum is full of soapy water.
How to Fix:
- Locate the small door at the bottom front of your washer.
- Place a towel down and use the emergency drain tube to empty the water into a bowl.
- Unscrew the large debris filter and remove coins, hairpins, or lint.
- Check the drain hose height; it should not be higher than 90 cm from the floor.
Cost vs. Replace: Cleaning is free. If the pump is making a grinding noise, a replacement costs roughly $50–$80.
A faulty pump or a kinked hose is the most common reason for a [Samsung drain issue], and it’s usually something you can fix yourself without a pro.
3. DC / dE / UE: The Balance Headache
Symptoms: The machine tries to spin, shakes violently, and resets the timer back to 9 or 11 minutes.
How to Fix:
- Redistribute: Open the door and break up balls of heavy towels or jeans.
- Leveling: Use a spirit level tool. Adjust the feet of the washer so it doesn't rock when pushed.
- Vibration Reduction: In 2026, we recommend using anti-vibration pads if your washer is on a wooden floor.
Expert Tip: If the UE code appears even when empty, your suspension rods (shocks) are likely worn out and need replacing.
4. 3C / 3E / 3CP: Motor Drive Error
Symptoms: The display shows the code, and the drum won't rotate at all, even though you hear the relay click.
How to Fix:
- Hard Reset: Unplug the washer for 30 minutes to let the motor capacitor discharge.
- Check for Obstructions: Try rotating the drum by hand. If it’s jammed, a garment might be stuck between the tub and drum.
- Wiring Check: If you are comfortable, open the back panel and check if the wire harness to the motor is loose.
Expert Tip: 3C errors are often caused by the Hall sensor. It’s a $20 part that saves you from buying a $200 motor.
5. tC / tE / tC1: Temperature Sensor Issues
Symptoms: The washer stops mid-cycle, usually during a Sanitize or Hot wash.
How to Fix:
- Check the wiring to the thermistor (located near the heater).
- Use a multimeter to check resistance. At room temperature, it should read approximately 10k-12k ohms.
2026 Update: Newer AI models may trigger this if the ambient room temperature is below freezing (common in garage installs).
6. OC / OE / 1C: Overflow & Level Sensor
Symptoms: The washer keeps filling with water until it reaches the glass, or it falsely thinks it is overflowing.
How to Fix:
- Detergent Check: If you see suds, it’s a false overflow. The bubbles trip the sensor.
- Pressure Tube: Check the thin plastic tube connected to the water level sensor. If it’s pinched or clogged with gunk, the sensor won't work.
- Sensor Replacement: If the tube is clear, the pressure switch (sensor) is likely faulty ($25–$40).
7. LE / LC / LE1: The Leakage Warning
Symptoms: The washer stops and leaks. The sensor at the base detects moisture.
How to Fix:
- Inspect the Boot: Look for tears in the large rubber door seal.
- Filter Check: Ensure the bottom debris filter is screwed in perfectly straight.
- Detergent Overdose: Using too much soap causes oversuds, which leak out of the back air vent, tripping the LE sensor.
Expert Tip: Tilt the machine slightly back to let the base pan dry. Often, the error clears once the sensor is dry.
8. Sud / 5Ud: The Soap Suds Lockdown
Symptoms: The machine pauses and displays Sud. It refuses to drain or spin.
How to Fix:
- Wait: Do not add more water. The machine is in Suds Suction mode. It will wait for bubbles to dissolve.
- Clean Out: Once the cycle ends, run a Tub Clean or a hot cycle with no detergent.
The Fix: Switch to HE (High Efficiency) detergent only. In 2026, even natural detergents must be HE-rated for Samsung AI washers.
Excessive 'scrud' buildup is a major cause of sensor errors. Instead of expensive tablets, use an [Affresh alternative] like soda crystals to keep your drum residue-free.
How to Perform a Hard Reset (The 2026 Method)
Modern Samsung washers are essentially computers. When the software glitches, a hard reset is your best friend:
- Disconnect the power cord from the outlet.
- Hold the Start/Pause button for 10 seconds.
- Wait exactly 15 minutes (this clears the memory on the PCB).
- Plug it back in and start a quick wash with no clothes.
Using Samsung SmartThings & Diagnostic Mode
In 2026, you shouldn't guess. Use the Samsung SmartThings App:
- Open the app and select your washer.
- Go to HomeCare Wizard.
- It will show you exactly which part is failing.
- Manual Diagnostic: On many models, holding "Temp" and "Spin" while pressing Power enters the test mode, allowing you to test the pump and motor individually.
Preventing Future Errors: The 30-Day Rule
To extend your washer's life by up to 30%, follow this maintenance schedule:
- Every 30 Days: Run the Self Clean or Tub Clean cycle with a dedicated cleaner tablet.
- Every 2 Weeks: Rinse the bottom debris filter.
- Every 6 Months: Check the rubber hoses for "bubbles" or cracks. Replace them every 5 years regardless of their appearance.
Frequently Asked Questions (FAQ)
Q: Can I ignore a 4C error and keep restarting?
A: No. Repeatedly restarting can burn out the water inlet valve solenoid or damage the main control board.
Q: Why does my Samsung washer show "DC" even with a small load?
A: Small loads are actually harder to balance than full loads. One heavy item (like a single hoodie) will clump to one side. Add a few towels to balance it out.
Q: Is it worth fixing a 3C motor error?
A: If your machine is under 10 years old, yes. Samsung Motors often has a 10-20 year warranty. Check your manual before paying a technician.
