The 22E error on your Samsung Washer means the main control board has lost communication with a sub-component, usually the display panel or a sensor circuit. This same code also shows up on Samsung freezers and refrigerators as a communication fault between boards. A power reset often clears it, but repeated errors point to a wiring or board issue.

Error code 22E
Meaning Communication error between the main PCB and a sub-board or sensor
Severity Medium — the appliance may stop mid-cycle or refuse to start until fixed
Time to fix 10–40 minutes
Tools needed Screwdriver, multimeter (optional, for wiring checks)

What the 22E error means

Samsung appliances use a network of small circuit boards that talk to each other to run sensors, displays, and motors. The 22E code appears when the main control board sends a signal and doesn’t get the expected reply back from a connected part, such as the sub PCB or a wiring harness link. It’s a communication fault rather than a specific part failure, so the actual cause can vary from a loose connector to a damaged board.

On washers this usually interrupts a wash cycle and locks the display. On freezers and fridges, the same fault logic can trigger the code if a sensor or display board drops offline.

Common causes

  • Loose or corroded wiring connector between the main board and sub board
  • Temporary power surge or brownout that disrupted board communication
  • Faulty main control board (PCB) that has stopped sending or reading signals correctly
  • Faulty sub-control board or display panel
  • Damaged wiring harness from pinching, moisture, or rodent damage
  • A failed firmware update or software glitch on newer Wi-Fi connected models

How to fix the 22E error

  1. Power cycle the appliance — Unplug it (or switch off at the breaker) for 2–3 minutes, then plug it back in. This clears many temporary communication glitches.
  2. Check the door/lid is fully closed — On washers, an unlatched door can trigger board communication errors. Make sure it clicks shut properly before restarting.
  3. Inspect visible wiring connectors — Unplug the unit, remove the back or control panel cover, and check that connectors between the main board and sub board are firmly seated and free of corrosion.
  4. Test with a multimeter — If comfortable doing so, check continuity on the wiring harness between boards. A broken wire will show no continuity and needs replacing.
  5. Inspect or replace the sub PCB — If wiring checks out, the sub-control board itself may have failed and typically needs professional replacement.
  6. Replace the main control board — If the error persists after all other checks, the main PCB is the most likely cause and should be replaced by a qualified technician.

FAQ

Can I keep using my Samsung washer with a 22E error showing?
It’s best not to. The error usually stops the cycle from completing, and repeated attempts can put extra strain on the control boards.

Does a power reset always fix the 22E code?
Not always, but it resolves the issue in many cases where it was caused by a temporary glitch rather than a hardware fault. If it returns quickly, the cause is likely a wiring or board problem.

Is 22E the same as other Samsung communication errors like SE, TE, or DE?
They’re related in that all are communication or sensor faults, but each points to a different part of the system. If you’re troubleshooting a Samsung appliance, it’s worth also checking guides such as the Samsung Washer SE Error Code: Causes and Fixes, Samsung Washer TE Error Code: Causes and Fixes, Samsung Washer DE Error Code: Causes and Fixes, and Samsung Washer LE Error Code: Causes and Fixes for comparison.
