Reviewed by Lukasz Zelezny for the Stannah range. Stannah makes stairlifts installed across UK homes, and their faults mirror the wider market: charging-point beeps, interlocks on the swivel seat, obstruction sensors, and batteries at end of life. Each Stannah check here is written for owners to use safely, with a plain statement of when a service engineer should attend instead.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Stannah fault on this page — full detail stays visible below either way.
Common Stannah Faults
The stannah lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine Stannah maintenance rather than a call-out, and the rest are far quicker to fix when you can describe the symptom precisely to whoever handles your Stannah repair.
Stannah stairlift seat swivel not locked
Owner-safe checkThe Stannah chair will not travel because the seat isn't sensing as locked in the forward position.
Before you phone anyone about a Stannah repair, work through the description below.
Every UK stairlift, Stannah included, interlocks the seat swivel: the chair will not travel unless the seat is locked either facing forward for travel or rotated to the safe dismount angle for exit.
On manually swivelled Stannah chairs, press down firmly on the seat cushion and rotate it through the click. You should feel a positive lock.
On powered swivel Stannah models, the swivel motor runs for a couple of seconds and only reports the seat as locked once the motion is complete.
Pressing the joystick during the swivel cycle produces exactly this fault. If the chair still refuses to travel with the seat visibly forward, the swivel micro-switch beneath the seat needs adjustment or replacement.
This is a Stannah engineer task rather than an owner adjustment. Where the checks do not settle it, describe the symptom in your own words when you ask for Stannah repair.
A plain description helps far more than a guessed diagnosis.
Stannah stairlift battery not charging
Owner-safe checkThe Stannah stairlift beeps a low-battery warning even after being left on charge overnight.
This symptom accounts for a steady share of the Stannah repair enquiries we see each month. A Stannah stairlift that won't take charge is a two-step check.
First, confirm the transformer plugged into the wall socket is live: most Stannah chargers have a small LED that lights when mains is present. The socket itself must be switched on.
Second, confirm the chair is fully parked on a live charging strip — a few centimetres short of the park position and the chair will beep but not charge.
If both are correct and the Stannah chair still won't hold charge, the internal 24V battery pack (two 12V sealed cells) is nearing end of life. Typical UK service life is 3–5 years.
Batteries at end of life still take charge but discharge in one or two trips.
A short entry in the Stannah maintenance log now avoids any later doubt about whether the fault was reported before the next Stannah servicing visit.
Stannah stairlift is beeping continuously
Owner-safe checkThe Stannah chair emits a continuous or repeating beep when parked or when a call is attempted.
This is one of the most common reasons UK owners look up Stannah troubleshooting in the first place.
Continuous beeping on a parked Stannah stairlift almost always indicates charging fault: either the chair is not seated on the charging strip, the mains socket is off, or the batteries have reached end of life and the chair is warning you they won't hold another trip.
The beep pattern is diagnostic on most brands — a slow single beep is a low-charge warning, a rapid multi-beep sequence points to a specific component.
On a Stannah chair, count the beeps and pauses and note the pattern. Your owner pack or service desk can interpret the sequence. Do not silence the beep by disconnecting the batteries.
That removes the Stannah chair's ability to warn of a real safety condition. Whatever the outcome, note the date and the symptom in your Stannah maintenance record.
A clear history makes the next Stannah servicing visit quicker.
Stannah stairlift key switch is in the wrong position
Owner-safe checkThe Stannah chair is completely dead — no lights, no beep — and the key was moved.
Of every Stannah troubleshooting question sent to us. This symptom is among the most frequent. Every UK stairlift has a key isolator, usually on the arm of the chair.
Turning the key to the off position disables the Stannah chair entirely. This is useful with young children in the house but frustrating when a carer arrives and can't find the key.
If a Stannah stairlift shows no lights and makes no beep, the first thing to check is the key: turn it to the on position and try again.
Spares are always supplied on fitting for a Stannah chair. Keep at least two somewhere every household member knows about.
If the key is really lost, Stannah can supply a replacement identified by the number stamped on the barrel. Write down what you saw and when.
Regular Stannah servicing catches most of these early, and good Stannah maintenance notes shorten the engineer's diagnosis.
Stannah stairlift remote control not working
Owner-safe checkThe wall-mounted Stannah remote does not call the chair, but it works from the arm control.
Read this through before booking any Stannah repair. The answer is often simpler than it looks. Wall-mounted remotes on a Stannah stairlift work on either infra-red line-of-sight or short-range radio.
If a call from the remote does not respond, but the chair works fine from the arm-mounted control. The fault is almost always in the remote itself.
Start with the remote batteries — most Stannah remotes take a single 9V or two AAAs and a low remote battery will simply stop transmitting.
Beyond that, remotes for Stannah chairs are a swap-in fob, so a lost, damaged, or de-paired remote can be replaced without opening the chair. Never remove the arm covers to investigate a remote fault.
The Stannah chair is still fully usable from its own arm control while a replacement is sourced.
If it becomes a repeat event, treat it as a Stannah servicing question rather than a one-off Stannah repair; recurring symptoms usually trace back to a missed maintenance interval.
Stannah stairlift obstruction sensors triggered
Owner-safe checkThe Stannah chair reports an obstruction even when nothing visible is in the way.
Most people arriving at Stannah troubleshooting pages describe the problem in roughly these words. If a Stannah chair repeatedly reports obstruction with the stair-path clear, the sensors themselves are the suspect.
The bumper switches under the footplate and along the carriage of a Stannah stairlift use small mechanical actuators; when they age they can become spongy and trip on nothing more than the Stannah chair's own movement.
Wipe the underside of the footplate and the sides of the carriage.
Run the chair slowly through the point where it usually reports the obstruction, and note whether the fault repeats in exactly the same position.
That pattern is what tells the Stannah service engineer whether the fault is a rug still in the way, a sensor drifting out of tolerance, or a bent actuator arm.
Keep the Stannah maintenance paperwork with the lift. Whoever attends the Stannah repair will want to see when the last service was done.
Stannah repair
Most enquiries that reach us are described as a Stannah repair, but roughly a third turn out to be a reset, a battery on charge, or a door edge that is not quite closing. Work through the checks above first and write down exactly what the stairlift does — the noise, the light, the floor it stops at. That note is what turns a vague call-out into a first-visit fix.
Anything behind a cover or panel, in the pit or shaft, or involving doors, gates and interlocks is engineer-only work. Your part of a Stannah repair is to check and report: mains power on, isolator on, emergency stop out, nothing in the door threshold, and a written note of the fault code.
What Noise Is Your Stannah Stairlift Making?
Lifts talk. Not eloquently — but a grind, a beep or an ominous silence each means something. Press play, compare, and pick the closest match.
Example sounds are synthesized approximations to help you compare — not recordings of Stannah equipment.
Grinding — likely causes on a Stannah stairlift
✅ Owner-safe check- Debris (carpet fibres, pet hair, small toys) fouling the rack or pinion
- Lack of lubrication on the rail after years of service
- A worn pinion gear or rack tooth reaching end of life
A grinding noise on a Stannah stairlift almost always comes from the rack-and-pinion drive on the underside of the rail.
Owner scope stops at looking: with the chair parked and the key switch off, check the visible rail for anything caught in the teeth, and note where on the rail the noise happens.
Do not try to lubricate, adjust or clean the pinion yourself. If the sound is new, is getting louder, or the chair also judders, book a service.
Grinding that gets worse is how a rack failure begins.
What Light Is Your Stannah Stairlift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Stannah stairlift
✅ Owner-safe check- Chair parked off its charging strip — the charge indicator has flipped from green to red
- Battery at end of life and no longer accepting a full charge
- A latched fault the controller is holding until service
Solid red on a Stannah stairlift is the controller saying it will not move until an open safety input is closed or a latched fault is cleared.
In practice the trigger is usually something ordinary that the person using the lift can see.
Take two minutes and park the chair fully on its charging point, swivel the seat back until the lock clicks, and clear anything resting on the footplate or against the armrests.
Should the light go out and normal travel return, no further action is needed. Should it stay on, the fault needs an engineer.
Leave the power on and send your service company a note of the indicator state.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
Safety-critical systems on your Stannah lift are engineer-only. Call your provider, or use the form below, when you notice:
- The same fault reappearing within minutes of a reset.
- Burning smells, smoke, or visible damage to cables or control panels.
- Water in the pit, machine room or car.
- The car running outside its normal range or stopping off-level.
- Doors, gates or interlocks that work only some of the time.
Stannah servicing
Stannah servicing intervals are set by the installer and by how hard the stairlift works: a domestic unit used a few times a day is not on the same schedule as one in constant use. If you have inherited the equipment with a property, ask the incoming provider for the last service sheet before agreeing a plan.
Keep every service sheet. A dated history of Stannah servicing tells the next engineer which parts have already been changed, supports any warranty claim, and is the first thing a buyer's surveyor asks for when the property changes hands.

Stannah maintenance
Day-to-day Stannah maintenance is mostly housekeeping, and all of it is safe from outside the equipment: keep charge points and landings clear, keep the stairlift on power rather than isolating it between uses, and keep the door threshold free of grit, rugs and packaging.
Nothing in owner-level Stannah maintenance involves removing covers, entering the pit or shaft, or adjusting doors, gates or interlocks. If a check cannot be done from the landing with the equipment behaving normally, it belongs to a qualified engineer.
Frequently Asked Questions
Is my own Stannah stairlift covered by this page?
Stannah is a stairlift / microlift manufacturer active in UK (global). The ranges most often met in the UK are 600/260 Siena, Starla, Sofia, Sadler; Microlifts.
The fault-finding below is written around the behaviour those Stannah ranges share rather than around one model number.
So start here and then confirm your exact model from the rating plate before you quote anything to an engineer. One thing worth knowing: the reference note for Stannah reads "Family-owned.
US arm via Stannah Stairlifts Inc". This can change whose manual actually applies to your machine.
Where does a Stannah stairlift show its fault code?
On Stannah equipment the sign is described as: User display codes 1–9 + ECU LED fault groups.
Codes are not standardised between makers, or even between board generations within Stannah, so photograph exactly what you see.
The characters, the lamp colour, the flash pattern — and report that with the model from the plate. Read the sign; do not open the Stannah controller or any panel to chase it.
Which Stannah problem comes up most often?
The fault this page opens with is "Stannah stairlift seat swivel not locked". The Stannah chair will not travel. Because the seat isn't sensing as locked in the forward position.
The next most reported Stannah symptom is "Stannah stairlift battery not charging". Work through the safe checks listed against each one, note what you observe, and pass that to a competent lift engineer.
All on this page stops at check-and-report: nothing here asks the user or their family to force a door, move a stalled car, remove a panel or enter a pit or shaft.
Is there an official Stannah source for fault information?
The authoritative reference for this brand is the Stannah 600 product support + install manual. Stannah publishes to its own channels and to registered trade accounts rather than openly.
So if you have no account, ask your maintenance contractor to supply the Stannah document that covers your fitting.
Our own coverage of Stannah is currently rated "Full user-level + engineer structure", so treat this page as an orientation and the manufacturer's document as the authority.
Will a Stannah stairlift work in a power cut?
Stannah stairlifts of this type run from an onboard battery pack. So the chair normally completes journeys during an outage and simply stops charging until the mains returns.
If your Stannah chair will not run on battery at all, that points at the batteries or the charging circuit rather than the outage. The checks on this page separate the two.
