Why does the Kruskal's Swirl gelato base give error code PZ-4042 during freezing?
I'm trying to replicate the "Kruskal's Swirl" puzzle‑themed ice cream from the 2022 Gelato Lab series. The recipe calls for a 7.2% guar‑gum suspension (batch #GS-07) and a rapid‑freeze cycle using the IceMaster 3500 (firmware v3.1.4).
When I start the cycle the machine displays error code PZ‑4042 and halts. I've double‑checked the following:
- Guar‑gum concentration: measured at 7.18% (refractometer X‑200)
- Salt brine temperature: -8 °C (consistent across cycles)
- Whisk speed: 1,200 rpm (per spec)
- Batch volume: 2.5 L (within 250 ml tolerance)
What triggers PZ‑4042? Is it a stability issue with the polymer mesh, or could the 0.3 mm honeycomb seed crystals be too large for the current churning profile? Any insight or a known firmware tweak would be appreciated.
