What SS (Pantry / Water Tank Sensor) Means
SS indicates a shortened or open sensor, per LG's error-code list and digital reference, which requires professional inspection either way. The two LG documents describe the sensor slightly differently - the main error-code list calls it the pantry sensor, while the digital-and-analog reference describes SS as a water tank temperature sensor - so this entry hedges which component it is rather than guessing; the exact part depends on the model.
Common Causes of SS (Pantry / Water Tank Sensor)
- Pantry compartment or water tank temperature sensor has failed (component varies by model)
- Sensor wiring has come loose
🔧 One Safe Check You Can Try
There's no owner-level fix LG documents for SS; a single power-cycle is worth trying, but if the code returns the specific sensor needs technician diagnosis to identify.
⚠ Why You Shouldn't Go Further Than That
- Because LG's own two documents don't agree on which sensor SS refers to, a technician needs to check your specific model rather than guessing which part to replace.
- Both the possible sensors sit inside compartment liners, not somewhere accessible without partial disassembly.
