What this guide covers

Error codes: rS

This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Continue this exact diagnostic

Safe troubleshooting sequence

This reviewed path begins with a direct owner-safe action or status check rather than a branching question. Follow the step below, then use the interactive diagnostic if the condition persists.

  1. Turn the appliance off and disconnect power for about 60 secondsUse the breaker when the plug is not safely accessible.
  2. Restore power and retry the original function onceDo not repeatedly clear a returning code.

A persistent return points to an internal condition that needs qualified diagnosis.

Evidence strength: Strong

When professional diagnosis is the safer next step

A persistent return points to an internal condition that needs qualified diagnosis.

Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.

Repair or replace?

A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
