All troubleshooting →- Symptom
Food isn't fully dry — especially on the center trays
Why center-tray food comes out cool, flexible, or dark in the middle — and the checks that fix it, in the order to try them.
- Symptom
Candy is chewy, melted, or didn't puff
Chewy centers, melted puddles, or candy that never puffed — each failure has a distinct cause: spacing, settings, or a candy that fundamentally won't work.
- Symptom
Rehydrated food is tough, mushy, or tastes flat
Rehydration failures trace back to three places: how the food was dried, how it's being rehydrated, and what that food can ever be again. Sorting them out — with the food-safety rule that applies.
