Common questions

What do appliance error codes mean?

An error or fault code is your appliance telling you which system it thinks has a problem — a drain error, a fill error, a heat error, a sensor fault, and so on. It narrows down the cause, but the code is a starting point, not the whole diagnosis. This page lists what the common codes mean by brand.

How do I clear an appliance error code?

Many codes clear once the underlying issue is fixed — clean the filter, open the valve, clear the vent. For a one-time glitch, cutting power for a minute (unplug, or flip the breaker) often resets it. If the code comes right back, it's pointing at a real problem — find your code above for what to check.

Do the same codes mean the same thing on every brand?

No — a code like "F2" or "OE" means different things on different brands, and even different things across model years within a brand. Always match the code to your specific brand and appliance, which is how this reference is organized.

Can you fix my appliance if it's showing an error code?

Yes — we're a real technician-led shop, and error codes are our daily work. Start a $50 Quick Check with your code and a short video, and a real tech gives you an honest answer on what it is and what it costs. We serve Middle Tennessee and the Baton Rouge area in-home, plus nationwide video diagnostics.
