Equipment Maintenance & Care: The Complete Technical Guide

1. Machine Won’t Power On

90% fix rate with these checks: Test the outlet with another device (confirms power supply). Check the rear master power switch (many machines have a secondary switch on the back panel — easily overlooked). Check circuit breaker (aesthetic machines on a shared circuit with other high-draw equipment can trip breakers). Verify voltage converter wattage if applicable.

Still dead? Unplug for 60 seconds, then reconnect. Many machines have thermal protection circuits that trip if the unit overheated during the previous session. This reset resolves most “won’t power on” issues after the machine has been running heavily. If still unresponsive: contact support. Do NOT open the casing — high-voltage components inside are dangerous and opening voids your warranty.

2. Reduced Treatment Effectiveness

Cause #1 (90% of cases): Product buildup on treatment heads. Gel, cream, and skin oil residue create a barrier reducing energy delivery by 20–40%. Deep clean with enzymatic cleaner (not just alcohol wipes — they don’t break down protein-based residue). Cause #2: Wrong conductive gel type. Some machines require water-based gel, others glycerin-based. Incorrect gel reduces RF and ultrasound transmission by 30–50%. Check your manual. Cause #3: Settings accidentally reset (common after firmware updates or power interruptions). Verify against your documented treatment protocols.

3. Unusual Noises

Normal sounds: Steady humming from transformer/power supply (constant), clicking from relay switches during mode changes (intermittent), fan noise increasing during heavy use (thermal management working correctly). Abnormal sounds (stop immediately): Grinding or scraping (bearing failure), rattling (loose internal component), high-pitched whining (electrical issue), buzzing that changes pitch erratically (power regulation problem). These indicate internal mechanical or electrical issues requiring professional service.

4. Error Codes and Screen Messages

Document the EXACT code or message displayed. Check your user manual’s error code appendix — most common codes have simple solutions: handpiece not fully seated in its connector (remove and reconnect firmly), water reservoir empty or below minimum line, overheating protection engaged (allow 10-minute cooldown with the machine powered on). For codes not listed in your manual: photograph the screen and contact support with: the code, what treatment was being performed, and how long the machine had been running. Most error codes can be resolved remotely via video call.
