Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Stiltz fault on this page — full detail stays visible below either way.
Common Stiltz Faults
The stiltz lift problems reported most often to UK service desks — expanded in the order owners typically encounter them.
Stiltz home lift won't move when called
Owner-safe checkThe car lights up but nothing happens when a floor is selected on your Stiltz home lift.
When a Stiltz home lift refuses to move on call the safety circuit is almost always the reason. Every UK home lift, Stiltz 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, and 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 Stiltz 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.
Stiltz home lift stuck between floors
Engineer onlyThe Stiltz home lift has stopped mid-travel and is not responding to calls or in-car controls.
A Stiltz 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 Stiltz car, use the alarm bell or the intercom, call the service line printed inside the car, and if anyone in the car has a medical need call 999. The manual hand-lowering procedure on some Stiltz lifts is a controlled release documented in the owner pack but is intended to be walked through by the manufacturer's helpline, not attempted from memory. Waiting for an engineer is always safe; forcing anything is not.
Stiltz home lift door or sensor fault
Owner-safe checkYour Stiltz lift is showing a door open warning when the doors look closed.
Home lift doors are safety-critical: any door that the Stiltz 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 a Stiltz 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 an hour of on-site diagnosis when they arrive.
Stiltz home lift shows a warning light
Owner-safe checkA warning indicator on your Stiltz home lift is lit or flashing.
Every UK home lift brand uses a different indicator scheme for faults and Stiltz 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, and — if you have one — write it in your lift owner log before doing anything else. A single controlled reset is usually appropriate on a Stiltz 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 Stiltz service engineer needs the sequence of dates to diagnose the underlying cause rather than the surface symptom.
Emergency stop engaged on the Stiltz home lift
Owner-safe checkThe Stiltz lift is completely dead and the red stop button is depressed.
If a Stiltz 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 Stiltz carriage — designed to be pressed in the event of a passenger emergency. To release, twist gently clockwise (or in the direction indicated 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 Stiltz lift, log it — repeated accidental knocks on the stop button may mean it needs relocating out of the natural line of use.
Stiltz home lift travel is slow or juddery
Owner-safe checkYour Stiltz lift moves but not as smoothly or quickly as it used to.
Slow or juddery travel on a Stiltz home lift points to a mechanical wear issue rather than a safety-circuit lockout, and can be scheduled rather than treated as an emergency. On ball-screw Stiltz 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 Stiltz home lifts, low oil, air trapped in the ram, or a partly-clogged flow-control valve produces a similar hesitation. Continue to use the Stiltz 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.
What Noise Is Your Stiltz 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 Stiltz equipment.
Grinding — likely causes on a Stiltz 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 a Stiltz 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 Stiltz lifts each fail this way for different reasons, so the engineer will need that timing information to arrive with the right parts. Never look inside the shaft or under the car.
What Light Is Your Stiltz Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Stiltz 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
A steady red indicator on a Stiltz home lift means a safety input is open or a fault has been latched. Walk every landing door and the car gate and close each one deliberately, listening for the latch. Check every emergency stop — a quarter-turn clockwise releases them. If the red clears with those two checks, the lift is safe to use once it starts responding again. If it does not clear, do not keep re-trying the call button; leave the lift powered 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
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 Stiltz 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
How do I reset a Stiltz home lift after a fault?
Most Stiltz home lifts have a controlled reset built in: turn the key switch off, wait 30 seconds, and turn it back on, then re-select the floor. Do not open any panel to reach an internal reset button on the Stiltz controller — that is an engineer task and voids the safety certification of the reset.
Is my Stiltz home lift covered by LOLER?
A privately-owned Stiltz home lift used only by the household is normally outside LOLER but is still covered by the Machinery Directive and the Stiltz service schedule. Any Stiltz lift used in a home business or workplace context falls under LOLER and needs six-monthly thorough examinations.
How often should a Stiltz home lift be serviced?
Stiltz specifies two service visits per year on most UK residential installations. Skipping Stiltz services is the single most common cause of the door-interlock and battery faults listed on this page.
Can I still use a Stiltz home lift when it is showing a warning light?
Only if the Stiltz manual explicitly lists that light as a warning rather than a lockout. In practice, if the Stiltz lift refuses to accept a call it is telling you it is not safe to operate. Do not defeat interlocks or bridge switches to force operation.
Who do I email if my Stiltz home lift is out of contract?
Use the contact form on this Stiltz page — describe the model and what the display shows, and a UK specialist replies with the safe checks first and, if needed, a brand-matched engineer referral.
