Reviewed by Lukasz Zelezny for the Aritco range. Aritco is a home-lift range installed in UK dwellings under the Machinery Directive. This page covers the fault symptoms owners see most often and — importantly — separates the checks that are safe for the household to make from the diagnoses that must be referred to a competent lift engineer. Every Aritco fault below is written to be readable by a non-technical owner and to hand the engineer a clean brief when a call-out is unavoidable.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Aritco fault on this page — full detail stays visible below either way.
Common Aritco Faults
The aritco lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine Aritco 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 Aritco repair.
Aritco home lift won't move when called
Owner-safe checkThe car lights up but nothing happens when a floor is selected on your Aritco home lift.
This is one of the most common reasons UK owners look up Aritco troubleshooting in the first place.
When an Aritco home lift refuses to move on call the safety circuit is almost always the reason. Every UK home lift, Aritco included.
Will not accept a call until every door and gate is fully closed. No emergency stop button is pressed on the car or the landings. The key switch is in the running position.
Owners can safely walk each landing door and confirm it is latched, twist any pressed red stop buttons gently clockwise until they release, and turn the key isolator through off and back on.
If the Aritco lift still refuses to move after those checks, the fault is inside the controller or the drive and the correct next step is to log the warning shown, describe the symptom, and refer to a lift engineer for reset.
Whatever the outcome, note the date and the symptom in your Aritco maintenance record. A clear history makes the next Aritco servicing visit quicker.
Aritco home lift stuck between floors
Engineer onlyThe Aritco home lift has stopped mid-travel and is not responding to calls or in-car controls.
Of every Aritco troubleshooting question sent to us. This symptom is among the most frequent.
An Aritco home lift stopped between floors is almost always the safety chain having opened during travel — an interlock lifted, a door sensor triggered, or an overload switch activated.
The single most important rule is do not force any door open. If someone is inside the Aritco car, use the alarm bell or the intercom, call the service line printed inside the car.
If anyone in the car has a medical need call 999.
The manual hand-lowering procedure on some Aritco lifts is a controlled release documented in the owner pack but is intended to be walked through by the manufacturer's helpline, not tried from memory.
Waiting for an engineer is always safe; forcing anything is not. Write down what you saw and when.
Regular Aritco servicing catches most of these early, and good Aritco maintenance notes shorten the engineer's diagnosis.
Aritco home lift door or sensor fault
Owner-safe checkYour Aritco lift is showing a door open warning when the doors look closed.
Read this through before booking any Aritco repair. The answer is often simpler than it looks.
Home lift doors are safety-critical: any door that the Aritco controller does not read as closed will lock the whole lift out.
The commonest causes are a magnetic reed sensor knocked slightly out of alignment on a landing door, a light-curtain lens on the car opening obscured by dust or a sticker, and a mechanical latch that has slowly drifted out of adjustment.
Owners of an Aritco home lift can safely wipe the sensor face and the door threshold, remove any obstruction, and cycle the door slowly to see if the fault clears.
If the display names a specific door, note which floor and which side — that saves a service engineer at least half a hour of on-site diagnosis when they arrive.
If it becomes a repeat event, treat it as an Aritco servicing question rather than a one-off Aritco repair; recurring symptoms usually trace back to a missed maintenance interval.
Aritco home lift shows a warning light
Owner-safe checkA warning indicator on your Aritco home lift is lit or flashing.
Most people arriving at Aritco troubleshooting pages describe the problem in roughly these words. Every UK home lift brand uses a different indicator scheme for faults and Aritco is no exception.
The important owner discipline is the same regardless of brand: note the light colour and pattern. The time, whether the lift was in use or parked.
— if you have one — write it in your lift owner log before doing anything else.
A single controlled reset is usually appropriate on an Aritco home lift and is described in the owner pack. Repeated resets of the same warning are not.
If the same warning returns within days of a reset it points to a component drifting toward failure, and the Aritco service engineer needs the sequence of dates to diagnose the underlying cause rather than the surface symptom.
Keep the Aritco maintenance paperwork with the lift. Whoever attends the Aritco repair will want to see when the last service was done.
Emergency stop engaged on the Aritco home lift
Owner-safe checkThe Aritco lift is completely dead and the red stop button is depressed.
Before you phone anyone about an Aritco repair, work through the description below.
If an Aritco home lift stops responding entirely, the two things to check before anything else are the emergency stop button and the key isolator. The red emergency stop is a twist-release button.
Usually mounted on the car and sometimes also on the top of the Aritco carriage — designed to be pressed if there is a passenger emergency.
To release, twist gently clockwise (or in the direction showed by the arrow on the button) until the button pops back out.
The key isolator is either on the car or a landing; turn to the "run" position. If clearing either restored the Aritco lift, log it.
Repeated accidental knocks on the stop button may mean it needs relocating out of the natural line of use.
Faults in this family are largely prevented by keeping to the Aritco servicing schedule, so check the date of your last Aritco maintenance visit while the paperwork is out.
Aritco home lift travel is slow or juddery
Owner-safe checkYour Aritco lift moves but not as smoothly or quickly as it used to.
This symptom accounts for a steady share of the Aritco repair enquiries we see each month.
Slow or juddery travel on an Aritco home lift points to a mechanical wear issue rather than a safety-circuit lockout. Can be planned rather than treated as an emergency.
On ball-screw Aritco models, insufficient lubrication of the screw column or a worn drive nut slowly reduces travel speed and adds a mechanical grind you can hear from outside the car.
On hydraulic Aritco home lifts, low oil, air trapped in the ram, or a partly-clogged flow-control valve produces a similar hesitation.
Continue to use the Aritco lift while a service visit is booked, but do book it. Extended running on a partially-failed drive puts unnecessary stress on the motor.
The brake and the safety gear and turns a service into a repair. Add it to the log. Planned Aritco maintenance is always cheaper than reactive Aritco repair.
The log is what turns a vague complaint into a booked servicing job.
Aritco repair
Most enquiries that reach us are described as a Aritco 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 home lift 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 Aritco 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 Aritco Lift 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 Aritco equipment.
Grinding — likely causes on a Aritco lift
⚠️ Engineer only- Screw-drive nut or ball-screw at the end of its service life
- Guide-shoe wear against the rail
- Debris in the shaft that has worked its way onto a running surface
Grinding from an Aritco home lift means metal is meeting metal where it should not. Do not keep using it.
Bring the car to a landing, take the key switch out, and email your service company today with exactly where in the travel you can hear the noise.
Quiet at rest, loud on the way up, only near the top and so on. Screw-driven, hydraulic and traction Aritco lifts each fail this way for different reasons.
So the engineer will need that timing details to arrive with the right parts. Never look inside the shaft or under the car.
What Light Is Your Aritco Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Aritco lift
✅ Owner-safe check- Emergency-stop button pressed and not released on the car or a landing
- Landing door interlock reporting open — magnet reed bent or dirty
- A latched fault the controller is holding until manually cleared by service
On an Aritco home lift, a constant red light is a stop signal: something in the safety chain is open, or a fault has been recorded and latched.
Nine times in ten it is something in plain sight rather than a hidden electrical failure.
Take two minutes and walk every landing door and the car gate, close each one until you hear the latch. Make sure no emergency stop is still pressed (a quarter-turn clockwise releases them).
If those checks fix it, use the lift as normal.
If not, treat it as an engineer job: keep the supply on, stop cycling the controls, and email the exact light behaviour to your service provider.
On Aritco home lifts, the status symbol shows red for a serious fault. Treat it as an engineer call rather than a routine reset (per Aritco's own paperwork).
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
Stop at the safety-critical boundary. Your Aritco engineer takes it from there. Call them, or use the form below, if you notice:
- A fault that reoccurs within a couple of minutes of resetting.
- Burning smells, smoke, or damaged-looking cabling and controls.
- Water getting into the pit, the machine room or the car.
- The car travelling beyond its usual limits or stopping off-level.
- Doors, gates or interlocks that only sometimes work correctly.
Aritco servicing
Regular Aritco servicing is the cheapest fault prevention available. A visit typically covers the drive and safety circuits, battery condition, charge points, limit and door detection, and a test of the alarm — the same items that generate most emergency calls when they drift out of tolerance.
Keep every service sheet. A dated history of Aritco 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.

Aritco maintenance
The owner's share of Aritco maintenance is observation. Listen for new sounds, watch for a landing stop that is drifting out of level, and note anything that has changed since last week. Reporting a small change early is what keeps it from becoming a call-out.
Nothing in owner-level Aritco 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 Aritco home lift covered by this page?
Aritco is a platform / home lift manufacturer active in Sweden (global). The ranges most often met in the UK are HomeLift, HomeLift Access, 4000/6000/7000.
The fault-finding below is written around the behaviour those Aritco 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 Aritco reads "Gartec is the UK distributor". This can change whose manual actually applies to your machine.
Where does an Aritco home lift show its fault code?
On Aritco equipment the sign is described as: U1 error memory 1–18 via Err lamp + lights; SmartLift symbols.
Codes are not standardised between makers, or even between board generations within Aritco, 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 Aritco controller or any panel to chase it.
Which Aritco problem comes up most often?
The fault this page opens with is "Aritco home lift won't move when called". The car lights up but nothing happens when a floor is selected on your Aritco home lift.
The next most reported Aritco symptom is "Aritco home lift stuck between floors". 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 householder to force a door, move a stalled car, remove a panel or enter a pit or shaft.
Is there an official Aritco source for fault information?
The authoritative reference for this brand is the Control System Manual 7000 400. Aritco 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 Aritco document that covers your fitting. Our own coverage of Aritco is currently rated "Partial.
System + symbols", so treat this page as an orientation and the manufacturer's document as the authority.
Can I reset an Aritco home lift myself?
Only using a control the Aritco manual describes for the householder. Usually a key-switch cycle at the landing.
If the Aritco lift still refuses the call after that, it is telling you it is not safe to run. The next step is an engineer, not a second try.
Never open a panel to reach an internal reset, and never try to move the car or open a door by hand.
