Reviewed by Lukasz Zelezny for the Lehner Lifttechnik range. Lehner Lifttechnik is a platform-lift range installed in UK public buildings, schools, clinics and adapted homes. The fault-finding on this page is written for the building operator — the person in the office or on reception who takes the call when the lift stops working — and separates the safety-edge, gate-interlock and hold-to-run checks that a competent operator can make from the mechanical and hydraulic diagnoses that are engineer-only.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Lehner Lifttechnik fault on this page — full detail stays visible below either way.
Common Lehner Lifttechnik Faults
The lehner lifttechnik lift problems reported most often to UK service desks — expanded in the order owners typically encounter them.
Lehner Lifttechnik platform lift won't rise from the lower landing
Owner-safe checkThe Lehner Lifttechnik platform lift accepts a call but does not move upward.
A Lehner Lifttechnik platform lift that responds to a call but does not travel is almost always a safety-circuit interlock issue: a gate not fully closed on the platform or a landing, a magnetic reed switch out of alignment, or the hold-to-run button being released mid-call. Owners can visually confirm every gate on the Lehner Lifttechnik lift is fully latched, check that the platform's own gate is closed and reads as closed on the controller display, and confirm the operator is pressing the up arrow firmly and continuously — most UK platform lifts including many Lehner Lifttechnik models are hold-to-run in one or both directions and will stop the instant the button is released. Anything beyond those visual checks belongs with a competent Lehner Lifttechnik engineer.
Lehner Lifttechnik platform lift safety edge triggered
Engineer onlyThe Lehner Lifttechnik platform has stopped mid-descent and reports a safety-edge fault.
The safety edge along the underside of a Lehner Lifttechnik platform lift is a pressure-sensitive strip designed to stop the platform the instant anything is trapped as it descends. When it triggers with a visible obstruction — a mop bucket, a cable, a stray leaflet — remove the obstruction, then use the constant-pressure lower control if fitted to complete the trip. If the Lehner Lifttechnik safety edge triggers with nothing beneath the platform, the edge itself or its harness has failed and the platform must not be used until a Lehner Lifttechnik engineer has inspected it. The safety edge is one of the safety-critical components of any UK platform lift, and no operator work-around is appropriate.
Lehner Lifttechnik gate interlock will not clear
Owner-safe checkA landing gate on the Lehner Lifttechnik platform lift is reported as open even though it appears closed.
Half-height landing gates on a Lehner Lifttechnik platform lift use magnetic reed switches to prove closure to the controller. Dirt on the magnet face, a slightly bent gate frame following a knock, a loose reed cable, or an ageing switch will all report the gate as open. On a Lehner Lifttechnik lift the fault display usually names the specific landing, and owners can safely wipe the magnet face and the reed sensor with a soft cloth, close the gate again to make full contact, and try the call. If the same landing repeatedly reports open with the gate visibly closed, the interlock needs adjustment or replacement — a Lehner Lifttechnik engineer task rather than a building operator one.
Lehner Lifttechnik platform drifts down when parked
Engineer onlyYour hydraulic Lehner Lifttechnik platform lift descends slowly overnight from the upper landing.
On hydraulic Lehner Lifttechnik platform lifts a small amount of overnight drift — a few millimetres per hour — is normal ageing behaviour of the hydraulic seals. Anything visible over a working shift, particularly if the platform is more than a step below the upper landing when a user calls it in the morning, is a fault and needs an engineer. Do not attempt to top up the Lehner Lifttechnik hydraulic reservoir yourself; the fluid grade, the ram bleed sequence and the pressure setting on the Lehner Lifttechnik valve block are all specific and get set at commissioning. Continue to use the lift only if the drift is under a step; otherwise take it out of service until a competent engineer has inspected.
Lehner Lifttechnik hold-to-run button sticks or intermittent
Engineer onlyThe pendant on the Lehner Lifttechnik platform lift feels spongy or the platform stops mid-travel.
Hold-to-run buttons on a Lehner Lifttechnik platform lift see a very high number of press cycles in public settings — schools, clinics, community buildings — and eventually wear out. If a button on the Lehner Lifttechnik pendant feels spongy, sticks pressed in, or the platform stops randomly mid-travel and restarts when you release-and-repress, the button assembly is reaching end of life. This is a like-for-like part on most Lehner Lifttechnik models but is not a building-operator fit item: the wiring must be continuity-tested and the replacement must maintain the specific Lehner Lifttechnik switching characteristics for safety. Log the fault, describe the pattern, and refer to a Lehner Lifttechnik engineer.
Lehner Lifttechnik platform lift has lost power entirely
Owner-safe checkThe Lehner Lifttechnik platform lift has gone dark and the isolator switch has tripped.
A Lehner Lifttechnik platform lift that has gone completely dead has usually tripped its supply RCD or the local isolator. Building operators can safely check whether the isolator to the Lehner Lifttechnik lift is off and whether the supply RCD in the distribution board has tripped, resetting a tripped RCD once. If the RCD trips again immediately, do not keep resetting: a repeat trip is telling you an insulation fault is present on the Lehner Lifttechnik lift and needs a competent engineer to fault-find. Never remove any cover on the Lehner Lifttechnik controller or the pit; the fault-finding on a tripped supply always happens with the lift isolated at source.
What Noise Is Your Lehner Lifttechnik 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.

Grinding — likely causes on a Lehner Lifttechnik lift
⚠️ Engineer only- Screw-drive nut worn and needing replacement
- Guide shoes worn against the rail
- Debris in the pit that has migrated onto the platform track
Grinding on a Lehner Lifttechnik platform lift is a stop-using-it symptom. Bring the platform to the lower landing, turn the key switch off, and put the lift out of service until an engineer has been. Note the exact travel position where the grinding is loudest — bottom, top, mid-travel — and whether it happens going up, going down or both. Screw-driven Lehner Lifttechnik platform lifts and hydraulic platform lifts fail this way for very different reasons, so that detail changes what the engineer brings. Do not remove any covers on the drive or motor housing.
What Light Is Your Lehner Lifttechnik Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Lehner Lifttechnik lift
✅ Owner-safe check- Emergency-stop button pressed on a landing or the platform
- Gate interlock reporting open on one landing
- Latched fault — commonly a safety-edge trip that needs a controller reset
A steady red indicator on a Lehner Lifttechnik platform lift means a safety input is open or has latched a fault. Walk both landing gates and close each one firmly against the frame. Check every emergency stop — a quarter-turn clockwise releases them. Look under the platform edge for anything caught in the safety edge. If the red clears with those three checks, the platform is usable again. If it does not clear, the fault is latched and only an engineer can safely reset it — put the lift out of use to passengers and email your service company today.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
Owner checks stop where safety-critical systems begin. Call your service provider — or use the form below — if you see any of the following on your Lehner Lifttechnik lift:
- The same fault returns within minutes of a reset.
- Burning smell, smoke, or visible damage to cables or controls.
- Water ingress in the pit, machine room or car.
- The car has travelled outside its normal range or landing level.
- Doors, gates or interlocks show intermittent behaviour.

Frequently Asked Questions
Does a Lehner Lifttechnik platform lift need LOLER inspections?
Yes — a Lehner Lifttechnik platform lift in a workplace, school, clinic, office or public building is lifting equipment used at work and needs a six-monthly thorough examination under LOLER, plus a routine Lehner Lifttechnik service under the manufacturer's schedule.
Why does the Lehner Lifttechnik platform lift only work when I hold the button down?
That is the design. Under Building Regulations Approved Document M, most low-rise platform lifts including Lehner Lifttechnik are hold-to-run in one or both directions. Releasing the button stops the platform — that is the safety intent, not a fault.
Can a facilities manager reset a Lehner Lifttechnik platform lift?
Only the controlled resets built into the Lehner Lifttechnik operator interface — usually a key-switch cycle or a documented reset button. Never remove panels to reach the Lehner Lifttechnik controller; that voids the machine's compliance and puts users at risk.
Who is responsible for a Lehner Lifttechnik platform lift in a rented commercial building?
Usually the freeholder or their managing agent for the Lehner Lifttechnik lift itself, and the occupier for daily use, keys and a lift log. Check the lease. Either way, the Lehner Lifttechnik service contract details must be visible to whoever calls when the lift goes out of service.
