Fully Jarvis E-codes — Controller error family

What this error means

The Jarvis uses the same JieCang control family as UPLIFT, so its E-codes and recovery are near-identical: communication, overload, and position-mismatch errors.

Symptoms

• E-number on handset
• Uneven legs or no movement

Try this first (safe DIY steps)

1. Unplug 60 seconds, replug, wait 30 seconds
2. Hold Down until the desk bottoms out, rises slightly, and stops
3. Reseat leg cables at the control box

Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.

When to call a technician
