Stannah 600 Fault Codes

Code 1: Charging or battery fault

Charging Issue

Safe check: Check that the normal wall power switch and stairlift master power switch are switched on and confirm there has not been a household power cut.

When support is appropriate: If normal power is available and the charging fault remains, contact Stannah service support.

Code 2: No fault found / normal operating mode

Normal Status

Safe check: The code itself does not indicate a fault. If the stairlift still does not operate, contact Stannah support.

When support is appropriate: This is a normal status code. Contact support only if the stairlift is not behaving normally.

Code 3: Obstruction detected around the footrest or carriage

Check Required

Safe check: Check for an obvious obstruction around the footrest, carriage and travel path. Remove only loose objects that can be safely reached.

When support is appropriate: If no obstruction is visible or the code remains, contact Stannah support.

Code 4: Power key or on/off switch issue

Check Required

Safe check: Check that the power key is correctly inserted and in its normal operating position and that the normal on/off switch is switched on.

When support is appropriate: If the code remains, contact Stannah support.

Check Required

Safe check: Check that the seat and arms are correctly positioned for normal travel according to the user manual.

When support is appropriate: If the code remains, contact Stannah support.

Code 6: Immobiliser seatbelt not correctly fastened

Check Required

This applies where the optional immobiliser seatbelt is fitted.

Safe check: Check that the seatbelt is correctly fastened and fully clicked into place.

When support is appropriate: If the safe check does not clear the code, contact the manufacturer's support service or a competent stairlift engineer.

Code 7: Seat is not in its travelling position

Safe first checks to try

Make sure the lift is parked on its charging points and charging.
Check the isolator or key switch is on.
Ensure the seat is in position with the footrest down.
Clear the staircase and rail of anything that could trigger the safety sensors.

Our common stairlift problems guide explains these in more detail.
