Reviewed by Lukasz Zelezny for the KONE range. In UK offices, retail, hospitality, healthcare and residential buildings, KONE passenger and goods lifts are engineer-maintained. This page accepts that and works around it, giving a facilities manager the vocabulary to describe a KONE fault well, the right warning message to quote, and a realistic route to a quicker first fix.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely KONE fault on this page — full detail stays visible below either way.
Common KONE Faults
The kone lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine KONE 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 KONE repair.
KONE lift shows Out of Service and won't accept calls
Engineer onlyThe KONE commercial lift has fault-locked itself and the car display reads Out of Service.
This is one of the most common reasons UK owners look up KONE troubleshooting in the first place.
A KONE commercial lift showing Out of Service has fault-locked from the controller — an issue the drive. Brake, door or safety circuit has flagged and refuses to clear without engineer authority.
Facilities staff should note the exact wording on the KONE display.
The time of day, whether the car is stopped at a floor and level with the sill, and any noise or vibration that preceded the fault.
All of that goes to the KONE service desk on first call; nothing on a fault-locked lift is appropriate for building staff to touch. Do not reset the mains isolator to the KONE lift.
That clears the controller's own fault log and makes the underlying cause materially harder to trace on the first engineer visit.
Faults in this family are largely prevented by keeping to the KONE servicing schedule, so check the date of your last KONE maintenance visit while the paperwork is out.
KONE lift doors keep reopening and won't leave the floor
Engineer onlyThe KONE car doors close, then reopen without any command and the lift does not depart.
Of every KONE troubleshooting question sent to us. This symptom is among the most frequent. Repeating door-reopen cycles on a KONE lift are a safety-edge or light-curtain fault.
The full-height infra-red curtain across the KONE car opening detects anything from a shopping trolley left in the doorway to a strip of dust on the vertical lens.
Facilities staff can safely wipe the vertical rails of the KONE door opening with a soft cloth, remove any obvious obstruction from the sill, and see if the doors seat cleanly.
If they still reopen, log a call to the KONE service line. Do not force the doors closed and do not hold the door-close button.
The reopening behaviour is the safety-edge doing its job and defeating it is not appropriate. Add it to the log. Planned KONE maintenance is always cheaper than reactive KONE repair.
The log is what turns a vague complaint into a booked servicing job.
KONE lift stops slightly above or below the floor
Engineer onlyThe KONE car floor comes to rest 10–40 mm above or below the landing sill.
Read this through before booking any KONE repair. The answer is often simpler than it looks.
Levelling errors on a KONE lift are a trip hazard and must be reported the same day, ideally with the car out of service until an engineer attends.
On modern KONE traction lifts the drive re-levels the car automatically once passengers step in or out; when the re-level begins to drift or fails, it points to encoder feedback loss, brake wear, or drive gain adjustment.
On older hydraulic KONE fittings, the car sinking below the floor after a load steps out is a valve or seal issue. Building staff should not try any KONE isolator reset.
The correct action is to sign the car out of service on the KONE lift log and log the fault with the manufacturer's callout time in mind.
Where the checks do not settle it, describe the symptom in your own words when you ask for KONE repair. A plain description helps far more than a guessed diagnosis.
KONE display shows a warning message
Engineer onlyA status message or warning indicator has appeared on the KONE car operating panel display.
Most people arriving at KONE troubleshooting pages describe the problem in roughly these words.
Any message on the KONE car display beyond the floor indicator and direction arrows is a controller status intended to be read and logged.
The useful discipline for building staff is the same regardless of brand: photograph the display, note the time, note whether the KONE lift kept running or stopped, and pass all three to the service desk on the first call.
Do not clear the message by cycling the KONE mains isolator. That erases the controller's own log and materially delays the engineer's diagnosis on the next visit.
Repeated instances of the same KONE warning within a short window show a component drifting toward failure and should be treated as urgent.
A short entry in the KONE maintenance log now avoids any later doubt about whether the fault was reported before the next KONE servicing visit.
KONE lift alarm rings but the intercom is silent
Engineer onlyPassengers press the alarm on the KONE car and get no voice response.
Before you phone anyone about a KONE repair, work through the description below. Since 2018 every new commercial passenger lift in the UK, including KONE fittings.
Has been needed to have two-way voice communication from the car to a 24/7 monitored line.
When the alarm rings on a KONE lift and nobody answers, the emergency line is either not configured, the SIM in the KONE auto-dialler has expired, or the telecoms line into the machine room is down.
The auto-dialler unit on a KONE lift lives in the machine room and needs a monthly test call.
This is a building-owner compliance need and one of the most common items to fail a LOLER report.
Log the fault as urgent; a car with a non-working intercom must not be left in service. Whatever the outcome, note the date and the symptom in your KONE maintenance record.
A clear history makes the next KONE servicing visit quicker.
KONE lift ride is rough or noisy
Engineer onlyThe KONE car judders, vibrates or is markedly noisier than usual in travel.
This symptom accounts for a steady share of the KONE repair enquiries we see each month.
A KONE passenger lift developing a rougher ride than normal is a mechanical wear indicator: brake pads glazing, guide-shoe roller wear, rope wear, or bearing noise on the KONE traction machine.
Building staff should not diagnose any of these.
The intent of noting the change is to raise it with the KONE service contractor at the next planned visit rather than waiting for the ride to degrade to a fault-lock.
Describing the change ("noise now audible from floor 4 upward". "vibration on down travel only") is more useful than a generic complaint.
All mechanical work on the KONE lift is engineer-only and off-limits to building staff. Write down what you saw and when.
Regular KONE servicing catches most of these early, and good KONE maintenance notes shorten the engineer's diagnosis.
KONE repair
A genuine KONE repair starts with an accurate description of the fault, not with a part number. Record the error shown on the display or keypad, when it appears, and whether the commercial elevator behaves differently on the way up than on the way down. Engineers quote far more accurately from that detail, and you avoid paying for a diagnostic visit that only repeats what you already know.
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 KONE 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.
On a commercial installation, repair also has a paper trail. Log the fault with building management the same day, keep the reference, and make sure the report reaches the company holding the maintenance contract rather than a general facilities inbox.
What Noise Is Your KONE 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 KONE equipment.
Grinding — likely causes on a KONE lift
⚠️ Engineer only- Traction sheave or brake pad wear on a geared or gearless machine
- Guide-shoe wear against the rail
- Roller-guide bearing failure
Grinding from a KONE passenger lift is never a building-manager job.
Put the lift on Fireman's or Independent service if you can, or place a barrier at the landing, and open a priority ticket with your service company today.
Note the floor at which the noise is worst. Whether it is loudest on the up-run or the down-run. How long the sound has been present.
Do not enter the shaft, the pit or the machine room. Do not try to move the lift by hand. Building maintenance duty here is limited to reporting, barriering and logging.
What Light Is Your KONE Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a KONE lift
⚠️ Engineer only- Fault-latched shutdown on the controller
- Fireman's or Independent service engaged and locking the car out
- Door-fault indicator held until service reset
When a KONE lift holds a solid red light, it is telling you a safety circuit is broken or a fault has been stored.
The common causes here are the boring ones, which is good news. Do the visible checks in order. Watch the car and landing doors close cleanly.
Check nothing is holding a door edge. Confirm no car-stop or emergency switch has been left operated. A red that clears after those checks is fine to use once travel returns to normal.
A red that stays is latched. Leave the lift powered, stop retrying, and report the exact light state to your service provider.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
Do not keep resetting past these signs. Call whoever services your KONE lift — or use the form below — if you observe:
- The same fault coming back a few minutes after a reset.
- Burning smells, smoke, or damage to cabling or control gear.
- Water ingress in the pit, machine room or car.
- A car beyond its normal travel range or away from the landing.
- Intermittent behaviour from doors, gates or interlocks.
- Any mechanical fault on a commercial elevator — DIY scope is limited to checking mains power, noting what the display shows, and reporting to building management.
If this lift is in a workplace or managed building, see our LOLER thorough examination guide for the statutory inspection duties that sit alongside repair.
KONE servicing
Regular KONE 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 KONE 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.
Servicing is not the same as a statutory thorough examination. In a workplace or managed building the two run alongside each other — see our LOLER thorough examination guide for how the duties differ.

KONE maintenance
The owner's share of KONE 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 KONE 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.
In a managed building, maintenance records and fault reports should sit in the same log. When you report a defect, record who you told, when, and what they said — that log is what proves the equipment was kept in a safe condition.
Frequently Asked Questions
Is my own KONE lift covered by this page?
KONE is a commercial manufacturer active in Finland. The ranges most often met in the UK are MonoSpace, EcoSpace etc.
The fault-finding below is written around the behaviour those KONE 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 KONE reads "Restricted service docs".
This can change whose manual actually applies to your machine.
Where does a KONE lift show its fault code?
On KONE equipment the sign is described as: LCE 4-digit fault codes. Codes are not standardised between makers, or even between board generations within KONE, 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 KONE controller or any panel to chase it.
Which KONE problem comes up most often?
The fault this page opens with is "KONE lift shows Out of Service and won't accept calls". The KONE commercial lift has fault-locked itself and the car display reads Out of Service.
The next most reported KONE symptom is "KONE lift doors keep reopening and won't leave the floor".
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 building manager to force a door, move a stalled car, remove a panel or enter a pit or shaft.
Is there an official KONE source for fault information?
The authoritative reference for this brand is the KONE service org. KONE 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 KONE document that covers your fitting.
Our own coverage of KONE is currently rated "System-level", so treat this page as an orientation and the manufacturer's document as the authority.
Who is the dutyholder for a KONE lift under LOLER?
For a KONE passenger or goods lift in a workplace, the dutyholder is normally the building owner or their appointed managing agent: they arrange thorough examination by a competent person, keep the reports, and act on defects.
Your KONE maintenance contractor usually coordinates the inspection. However, the duty does not transfer to them.
