- Confirm power supply and PCB are outputting stable, correct voltages across all essential circuits to ensure reliable operation
- Inspect the display for any dim, flickering, or dead pixels, replacing any compromised sections to maintain full clarity and accurate readouts
- Verify that all buttons, knobs, and switches are functioning properly, providing precise and responsive control across all settings
- Conduct a thorough inspection of the water reservoir for any holes, rust, or other structural damage that may impact its integrity
- Fill the reservoir with water, checking closely for any external or internal leaks that could affect performance
- Examine the lid for any signs of wear or damage, replacing hinges and handles if necessary to ensure a secure and proper seal
- Inspect for any internal leaks originating from the water reservoir, confirming the unit’s internal plumbing integrity
- Conduct a comprehensive inspection of internal wiring for any breakages, tears, or wear; replace any underperforming or damaged components to maintain safe operation
- Examine internal insulation for signs of burns, breaks, or deterioration, replacing as needed to ensure thermal efficiency and safety
- Confirm that all feet are intact and that the bath sits level and balanced on a flat surface to prevent movement or instability
- Calibrate both temperature accuracy and uniformity using a NIST-traceable temperature probe, verifying compliance with specification standards
- Perform a detailed cosmetic inspection to confirm that all external surfaces and finishes meet aesthetic and quality standards
