For example, Program P07 is a dentin firing with vacuum, while Program P08 has a wider temperature range (403 °C up to 1200 °C).

| Error Code | Meaning (per manual) | Solution | | :--- | :--- | :--- | | | Thermocouple short circuit or broken wire. | Replace thermocouple (Part # 582926AN). Check wiring harness. | | E3 | Vacuum not reaching required level (-0.95 bar). | Check hose connections, oil level, and vacuum pump diaphragm. | | E5 | Temperature deviation exceeds ±10°C for more than 2 minutes. | Run calibration program. If persistent, replace heating elements. | | Door Error | Safety interlock failure. | Clean door seal. Adjust door latch tension per manual diagram. |

The thermocouple reading may be unstable. Contact a certified technician to recalibrate or replace the platinum sensor.

Over time, moisture, oxides, and ceramic binders contaminate the muffle. Run a de-contamination or "bake-out" cycle weekly. Elevate the furnace temperature to 1050∘C1050 raised to the composed with power C
