Severity: Low (Comfort) | Likely Result: Interior lights flicker or go dark.
What it means: The 24V or 110V lighting supply is drawing too much current (usually >2A).
Common Causes:
Troubleshooting: This won’t stop the car, but passengers will panic. Replace with Schindler-approved LED kits. schindler 5500 error codes top

Severity: High | Likely Result: Car runs but floor buttons and indicators are dead.
What it means: The main control lost contact with the Landing Operating Panel (hall call station).
Common Causes:
Troubleshooting: A single wet hall button can bring down the entire serial loop. Disconnect floor stations one by one to find the short.
Severity: Critical | Likely Result: Car locks up, heavy braking.
What it means: The drive inverter has detected a current draw exceeding the safety threshold. This is consistently the top error code for the 5500 model. Severity: Low (Comfort) | Likely Result: Interior lights
Common Causes:
Troubleshooting: Check mechanical brakes first. Then, measure resistance across motor windings (U-V, V-W, W-U). Finally, inspect the encoder feedback.
