Frequently Asked Questions
How do I know my heating element needs replacement?
Common signs: the steam generator runs but produces little or no steam, the boiler overheats or trips the thermal cutoff, or you see a significant drop in steam output. A licensed technician can test element resistance with a multimeter to confirm failure.
Can I replace the element myself?
Element replacement involves disconnecting line-voltage wiring (typically 208–240V) and draining the boiler. This work must be performed by a licensed electrician. DIY installation on line-voltage equipment may void the warranty and is against code in most jurisdictions.
Do I need to match the original wattage exactly?
Yes. The replacement element must match the original wattage and voltage rating. Using a different element can overheat the boiler, trip breakers, or cause permanent damage. Check the generator's data plate or original manual for the correct spec.
