Your appliance is showing a code.
Here is what the manufacturer says it means.
61 codes across 4 brand-and-appliance guides. Every page restates one manufacturer's own support documentation: the meaning, the checks in the order the manufacturer lists them, the parts involved, and the exact point where the manufacturer says to stop and request service. Sources are named and dated on every page.
How to use a code page
- Match the brand first. Codes are not shared: IE is a water inlet error on LG and a system error on Samsung. Reading the wrong brand's page is worse than useless.
- Work the checks in order. They run cheapest and most likely first — hoses and filters before parts.
- Respect the stop line. Where the manufacturer says service, the page stops too. No invented repair steps, nothing involving gas, refrigerant or mains wiring.
