What should I do if the stairlift restarts unexpectedly or fails to hold its charge despite attempts to reset?

If your stairlift restarts unexpectedly or will not hold its charge after a reset, stop using it and arrange a professional inspection. The fault may involve the batteries, charger, charging points, power supply, wiring, control system or a safety circuit, and repeated resets will not correct a component that is failing.

Before contacting us, carry out these safe checks:

• Move the stairlift to its designated charging position, usually at the top or bottom of the staircase, and leave it there.
• Check that the charger is switched on and that its plug has not been loosened or disconnected.
• Test the socket with another suitable appliance if you can do so safely. If the socket is not working, check the relevant household fuse box or ask a qualified electrician to investigate.
• Make sure the charging contacts on the stairlift and the charger are aligned and free from visible dust or obstruction. Do not scrape, bend or apply liquid to the contacts.
• Check whether the display, indicator light or spoken message shows a battery, charging, obstruction or safety fault.
• Ensure the seat, armrests, swivel seat, footrest and safety belt are fully in their normal travelling positions. A safety switch that is not engaged can prevent movement or cause the lift to stop.

If the stairlift has an approved user reset procedure, you can attempt it once after confirming that the lift is safely parked. Follow the instructions supplied with your specific model, as reset controls and sequences vary. Keep the staircase clear, remain seated only if the manufacturer’s instructions permit this, and do not repeatedly switch the lift on and off when it continues to restart.

Unexpected restarting is not normally explained by a simple low battery alone. It can occur when ageing batteries briefly lose voltage under load, when the charger is not maintaining the batteries, or when a loose connection, damaged cable, control-board fault or safety switch interrupts the electrical supply. A stairlift may appear to recover after a reset but fail again as soon as it carries a passenger or reaches a particular section of the rail. This is why an intermittent fault should not be treated as resolved merely because the lift works for a short period.

A stairlift that does not hold its charge may have batteries that have reached the end of their service life. It may also be left away from its charging point, have a failed charger or charging contact, or be affected by a power interruption. Reconditioned or replacement batteries must be the correct type and specification for the stairlift. Do not fit automotive batteries, alter the wiring or attempt to bypass the charger, as this can damage the equipment and create a safety risk.

Stop using the stairlift immediately if it restarts while travelling, moves erratically, produces a burning smell, becomes unusually hot, shows exposed or damaged wiring, or repeatedly stops between charging points. If it is stopped on the stairs, follow the emergency or breakdown guidance provided with the lift. Do not try to force the carriage, remove covers or climb around it while it is obstructing the staircase. If there is an immediate risk of injury, seek appropriate emergency assistance.

When you contact Independent Stairlifts, provide the stairlift model if known, the exact warning lights or sounds, whether the fault occurs during travel or while parked, how long the batteries remain charged, and what happened after the reset. This information helps our engineer assess whether the likely remedy is a battery or charger replacement, a connection repair, adjustment of a safety circuit or a more detailed electrical inspection.

Until the fault has been assessed, keep the stairlift switched off if the manufacturer’s instructions allow it, leave it at a charging point when safe to do so, and use an alternative method of accessing the stairs. A stairlift that repeatedly restarts or loses charge needs a proper diagnosis rather than continued resetting.
