Reviewed by Lukasz Zelezny for the TK Elevator range. TK Elevator supplies commercial passenger and goods lifts to UK buildings from small offices to hospitals. This page speaks to the facilities manager and to no one with a toolbox, because commercial lifts are engineer-only equipment.

Quick Diagnosis
Answer up to three questions. We'll point you at the most likely TK Elevator fault on this page — full detail stays visible below either way.
Common TK Elevator Faults
The tk elevator lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine TK Elevator 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 TK Elevator repair.
TK Elevator lift shows Out of Service and won't accept calls
Engineer onlyThe TK Elevator commercial lift has fault-locked itself and the car display reads Out of Service.
Of every TK Elevator troubleshooting question sent to us. This symptom is among the most frequent.
A TK Elevator 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 TK Elevator 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 TK Elevator 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 TK Elevator lift. That clears the controller's own fault log and makes the underlying cause materially harder to trace on the first engineer visit.
Write down what you saw and when. Regular TK Elevator servicing catches most of these early, and good TK Elevator maintenance notes shorten the engineer's diagnosis.
TK Elevator lift doors keep reopening and won't leave the floor
Engineer onlyThe TK Elevator car doors close, then reopen without any command and the lift does not depart.
Read this through before booking any TK Elevator repair. The answer is often simpler than it looks. Repeating door-reopen cycles on a TK Elevator lift are a safety-edge or light-curtain fault.
The full-height infra-red curtain across the TK Elevator 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 TK Elevator 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 TK Elevator 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.
If it becomes a repeat event, treat it as a TK Elevator servicing question rather than a one-off TK Elevator repair; recurring symptoms usually trace back to a missed maintenance interval.
TK Elevator lift stops slightly above or below the floor
Engineer onlyThe TK Elevator car floor comes to rest 10–40 mm above or below the landing sill.
Most people arriving at TK Elevator troubleshooting pages describe the problem in roughly these words.
Levelling errors on a TK Elevator 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 TK Elevator 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 TK Elevator fittings. The car sinking below the floor after a load steps out is a valve or seal issue. Building staff should not try any TK Elevator isolator reset.
The correct action is to sign the car out of service on the TK Elevator lift log and log the fault with the manufacturer's callout time in mind.
Keep the TK Elevator maintenance paperwork with the lift. Whoever attends the TK Elevator repair will want to see when the last service was done.
TK Elevator display shows a warning message
Engineer onlyA status message or warning indicator has appeared on the TK Elevator car operating panel display.
Before you phone anyone about a TK Elevator repair, work through the description below.
Any message on the TK Elevator 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 TK Elevator 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 TK Elevator 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 TK Elevator warning within a short window show a component drifting toward failure and should be treated as urgent.
Faults in this family are largely prevented by keeping to the TK Elevator servicing schedule, so check the date of your last TK Elevator maintenance visit while the paperwork is out.
TK Elevator lift alarm rings but the intercom is silent
Engineer onlyPassengers press the alarm on the TK Elevator car and get no voice response.
This symptom accounts for a steady share of the TK Elevator repair enquiries we see each month. Since 2018 every new commercial passenger lift in the UK, including TK Elevator 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 TK Elevator lift and nobody answers, the emergency line is either not configured, the SIM in the TK Elevator auto-dialler has expired, or the telecoms line into the machine room is down.
The auto-dialler unit on a TK Elevator 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. Add it to the log. Planned TK Elevator maintenance is always cheaper than reactive TK Elevator repair.
The log is what turns a vague complaint into a booked servicing job.
TK Elevator lift ride is rough or noisy
Engineer onlyThe TK Elevator car judders, vibrates or is markedly noisier than usual in travel.
This is one of the most common reasons UK owners look up TK Elevator troubleshooting in the first place.
A TK Elevator 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 TK Elevator traction machine.
Building staff should not diagnose any of these.
The intent of noting the change is to raise it with the TK Elevator 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 TK Elevator lift is engineer-only and off-limits to building staff.
Where the checks do not settle it, describe the symptom in your own words when you ask for TK Elevator repair. A plain description helps far more than a guessed diagnosis.
TK Elevator repair
Most enquiries that reach us are described as a TK Elevator 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 commercial elevator 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 TK Elevator 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 TK Elevator 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 TK Elevator equipment.
Grinding — likely causes on a TK Elevator 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 TK Elevator 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 TK Elevator Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a TK Elevator 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
Solid red on a TK Elevator lift is the controller saying it will not move until an open safety input is closed or a latched fault is cleared.
Most of the time the cause is mundane rather than mechanical. Before anything else, 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. If the red clears, the lift is safe to use once it responds normally again.
If it does not, stop pressing the call button, leave the power on, and email your service company with the exact indicator state.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
These are hand-over points, not fix-it points. Call whoever maintains your TK Elevator lift, or use the form below, if you see:
- Repeat faults within minutes of resetting.
- Burning smell, smoke, or visible damage to cables or controls.
- Water in the pit, machine space or car.
- A car outside its normal travel range or not level at the landing.
- Doors, gates or interlocks showing intermittent behaviour.
- 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.
TK Elevator servicing
Regular TK Elevator 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 TK Elevator 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.

TK Elevator maintenance
The owner's share of TK Elevator 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 TK Elevator 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 TK Elevator lift covered by this page?
TK Elevator is a commercial manufacturer active in Germany (global). The ranges most often met in the UK are TAC controllers (NA), evolution/synergy, EOX.
The fault-finding below is written around the behaviour those TK Elevator 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 TK Elevator reads "Restricted service docs".
This can change whose manual actually applies to your machine.
Where does a TK Elevator lift show its fault code?
On TK Elevator equipment the sign is described as: Controller fault log + MAX platform.
Codes are not standardised between makers, or even between board generations within TK Elevator, 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 TK Elevator controller or any panel to chase it.
Which TK Elevator problem comes up most often?
The fault this page opens with is "TK Elevator lift shows Out of Service and won't accept calls". The TK Elevator commercial lift has fault-locked itself and the car display reads Out of Service.
The next most reported TK Elevator symptom is "TK Elevator 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 TK Elevator source for fault information?
The authoritative reference for this brand is the TKE service org. TK Elevator 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 TK Elevator document that covers your fitting.
Our own coverage of TK Elevator 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 TK Elevator lift under LOLER?
For a TK Elevator 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 TK Elevator maintenance contractor usually coordinates the inspection. However, the duty does not transfer to them.
