It’s important to note that because wax is much more viscous than water, it traps heat differently. This can sometimes trigger the common E3 sensors errors if the heat isn't dissipating quickly enough from the base.

• Monitor Your Set Temperature: Since most wax melts around 165°F, there is usually no need to set the unit much higher than that. Keeping the set temperature closer to your target melting point prevents the base from over-firing.
• Use the Lower-Wattage Element Only: We recommend using only the smaller heating element (500W for the 35L model or 1000W for the 65L). Engaging both elements simultaneously can cause the temperature at the base to rise too rapidly for the wax to absorb, leading to an overheat error.
• Increase Stirring Frequency: Heat tends to build up at the bottom because wax doesn't circulate as naturally as thinner liquids. Stirring frequently helps redistribute that heat and prevents "hot spots" near the sensors.
• Try a Smaller Batch Size: A full tank of wax acts as a heavy insulator for the heating elements. If you are experiencing errors, try reducing the volume of wax in the unit. Less mass allows the heat to dissipate more effectively into the liquid.
• Continuous Supervision: Never leave the machine unattended while it is turned on or in operation.
• Material Safety: Never use the unit to heat flammable materials.
• Capacity Limits: When melting wax, do not fill the unit more than halfway. Because wax is denser and more insulating than water, filling it to the top can cause the heating elements at the base to overheat.

Cooling Precautions: Be mindful of leaving wax to cool completely inside the unit. As wax solidifies, it can create a powerful vacuum seal (acting like a "tight lid"), which can cause pressure issues or damage the components when the machine is turned back on.
