What F69 (Sous Vide Is Not Heating Properly) Means
F69 indicates the sous vide zone is not heating properly, per LG's range Help Library article, which documents this scheme across its Electric Range, Radiant Cooktop, and Gas Range tabs together - like F62, this has food-safety implications because sous vide cooking depends on sustained accurate temperature.
Common Causes of F69 (Sous Vide Is Not Heating Properly)
- Sous vide heating element fault
- Sous vide sensor fault
- Control board fault affecting the sous vide zone
🔧 One Safe Check You Can Try
Turn the circuit breaker for the range off, wait 30 seconds, and turn it back on; treat any food that was cooking sous vide when this code appeared the same way as with F62 - don't trust it stayed at a safe temperature.
⚠ Why You Shouldn't Go Further Than That
- As with F62, if you're unsure whether food maintained a safe temperature throughout an interrupted sous vide cook, the safer choice is to discard it rather than finish cooking and serve it.
- Don't attempt further sous vide cooks on this zone until a technician has confirmed the heating fault is resolved, given the food-safety stakes of an unreliable sustained-temperature cooking method.
