What the Pb error code actually means

The Pb code means your Samsung washer lost power while it was running a cycle, usually because of a brief outage, a tripped breaker, or a loose plug. The washer detected the interruption and paused to let you know. In most cases, pressing the Start/Pause button after power is restored will get the cycle going again.

Questions people ask about Pb

What does Pb mean on a Samsung washer?
Pb on a Samsung washer means electric service was lost while the machine was running a cycle. The washer detected a power interruption and stopped to alert you. It is not a mechanical failure code but a notification that the incoming power supply was disrupted. Pressing the Start/Pause button after power is restored will typically allow the cycle to resume.
How do I fix the Pb error on my Samsung washer?
Start by checking your home's circuit breaker panel for any tripped breakers and reset them if needed. Verify the washer's outlet is functioning properly and that the power cord is fully seated. If power is stable and the error still recurs, have an electrician inspect the outlet and circuit wiring. Persistent errors after confirmed stable power may require inspection of the washer's control board.
How much does it cost to repair a Samsung washer showing the Pb error?
If the cause is a tripped breaker or loose outlet, the repair may cost nothing or only the cost of an electrician visit, typically in the range of $75 to $150. If the wall outlet needs replacement, parts and labor usually fall between $50 and $200. A control board replacement, if required, is a more involved repair that can range from $150 to $400 or more depending on labor rates and part availability.
Will resetting the washer clear the Pb error code?
Yes, in most cases pressing the Start/Pause button will clear the Pb code and restart the cycle once power has been restored. If the code keeps reappearing, the underlying power supply issue needs to be addressed first. Simply resetting without fixing an unstable outlet or tripped breaker will result in repeated errors.
Is the Pb error on a Samsung washer a safety concern?
The Pb error itself is not a hazard, but it does mean the washer stopped unexpectedly with laundry and possibly water inside the drum. You should confirm that power has fully returned before restarting. If the error is caused by a faulty outlet or wiring problem, addressing that promptly is important to avoid electrical hazards unrelated to the washer itself.
