The F6 error code on a stairlift, often seen on models like the Acorn 180 Curved Stairlift, signifies an Over Limit Error. This indicates that the stairlift has moved beyond its designated operational boundary and has automatically shut down as a safety measure.
Understanding the F6 Error
When your stairlift displays an F6 code, it means the unit has gone past its normal limit on the track. Stairlifts are equipped with sensors and limit switches that define their safe travel path. If the lift exceeds these predefined stopping points—for example, by moving too far at either the top or bottom of the stairs—the F6 error is triggered. This automatic shutdown is a critical safety feature designed to prevent the lift from derailing, damaging itself, or creating a hazardous situation.
Troubleshooting the F6 Code
Resolving an F6 error primarily involves repositioning the stairlift. Here’s the most common solution:
- Hand-Winding the Lift: The most effective way to clear an F6 error is to manually move the stairlift carriage away from the end of the track. Many stairlift models include a manual winding mechanism (often operated with a specific tool or crank). Carefully engage this mechanism and wind the lift carriage a short distance back along the rail, moving it away from the point where it overran its limit. This action can reset the internal sensors and allow the lift to resume normal operation.
Important Notes for Troubleshooting:
- Always refer to your specific stairlift model's user manual for detailed instructions on how to hand-wind the unit and interpret error codes.
- If the F6 error persists after attempting to hand-wind the lift, or if it occurs frequently, it may indicate a deeper underlying issue with the lift's limit switches, control board, or motor. In such cases, it is highly recommended to contact a certified stairlift technician for a professional diagnosis and repair.
