Understanding the Problem
On Samsung dryers the rE (sometimes shown as RE or rE) code is a control/communication error that tells you the machine’s electronics aren’t agreeing or a component that reports to the main control is out of expected range. That can mean a failed main control board, a bad user interface (touchpad/display), a faulty door switch or motor feedback, wiring/connectors that are loose or shorted, or an intermittent power issue. Because rE is a generic electronic/communication fault, diagnosing it requires a step‑by‑step approach: verifying power/reset, checking connectors and wiring harnesses, confirming that buttons and the door switch behave correctly, and isolating whether the error follows the user interface (touchpad) or the main control board. Replacing electronics is commonly required only after these verifications because a loose connector or stuck button is an inexpensive fix compared with a PCB replacement.
Common Symptoms
Dryer displays rE (or RE) on the control panel; dryer may not start or will stop shortly after starting; control panel unresponsive or buttons act intermittently; intermittent operation or random shutdowns.
Common Causes
- Faulty main control board (electronic control PCB)
- Defective user interface / touchpad / display (control panel)
- Loose, damaged, or corroded wiring/connectors between control boards
- Stuck or faulty door switch or start button causing communication errors
- Power surges or intermittent supply problems damaging electronics

Helpful Repair Tip
Start by power‑cycling the dryer (unplug 5 minutes). If the rE persists, inspect/ reseat the connectors between the front control (display/touchpad) and the main control board; test the door switch and any visible wiring for continuity or damage before ordering a PCB.
Frequently Asked Questions
Can I clear the rE code and get the dryer running again?
Sometimes. Start with a full power reset (unplug 5–10 minutes) — this clears transient errors. If the code returns, check and reseat the control connectors and inspect the control panel buttons and door switch for stuck or damaged parts. If the error persists after those checks, the problem is likely a failed PCB or interface and will require replacement or professional diagnosis.
How much will it cost to fix an rE error?
Costs vary widely depending on the failed component. Replacing a simple part like a door switch or harness can be under $100 (parts+DIY labor). Replacing the main control board or user interface typically costs more — parts can range from about $120 to $400+ and professional labor adds $100–$250 depending on region. Always confirm the failed part with basic troubleshooting before buying electronics.
