The E-24 error on your Samsung Washer means the machine has detected a problem with the drain pump circuit or the door lock switch, depending on your model. Samsung Washer DE Error Code: Causes and Fixes covers a related door issue, but E-24 usually points to a pump or wiring fault that needs checking before you run another cycle.

Error code E-24
Meaning Drain pump circuit fault or door lock switch malfunction
Severity Medium — washer will not complete a cycle until resolved
Time to fix 15–45 minutes
Tools needed Multimeter, screwdriver, towel or shallow tray

What the E-24 error means

E-24 appears on Samsung washer displays when the control board doesn’t receive the expected signal from the drain pump or, on some models, the door lock assembly. This usually happens mid-cycle, often right before or during the spin phase. It’s a safety-related code, so the machine stops rather than risk draining incorrectly or spinning with an unlocked door.

Common causes

  • Drain pump wiring is loose, corroded, or disconnected
  • Drain pump motor has failed or is jammed with debris
  • Door lock switch is faulty or misaligned
  • Control board connector pins are damaged or dirty
  • A blockage in the drain hose is causing pump strain
  • Water residue has caused a short in the pump connector

How to fix the E-24 error

  1. Power cycle the washer: Unplug it for 2 minutes, then plug it back in and restart the cycle to see if the code clears.
  2. Check the drain hose and filter: Remove any lint, debris, or coins that could be blocking water flow and straining the pump.
  3. Inspect the drain pump wiring: Open the access panel, locate the pump, and check the connector for looseness, corrosion, or moisture damage.
  4. Test the pump with a multimeter: Check for continuity across the pump terminals; a reading of zero or infinite resistance means the pump needs replacing.
  5. Examine the door lock switch: Make sure it engages fully and the door closes flush; a misaligned latch can trigger a false E-24 reading.
  6. Replace faulty parts: If the pump or door lock switch tests bad, replace it with a genuine Samsung part rather than attempting a repair.

FAQ

Can I still use my washer if it shows E-24?
No, the cycle won’t finish safely until the fault is cleared, so it’s best to stop and troubleshoot before continuing.

Is E-24 the same as a door lock error?
Not always — on some Samsung models E-24 is pump-related, while door issues are more commonly flagged separately, as explained in Samsung Washer LE Error Code: Causes and Fixes.

Do I need a technician to fix this?
If wiring checks and hose clearing don’t work, a technician is recommended, especially if the pump motor needs replacing.
