Reviewed by Lukasz Zelezny for the Dalby range. Dalby is found in passenger and goods installations across UK commercial and residential buildings. Treat this page as a briefing tool rather than a repair guide — commercial lifts are engineer-only equipment. What it does offer a facilities manager is precise language for the fault, the right Dalby warning message to quote, and a faster route to first fix.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Dalby fault on this page — full detail stays visible below either way.
Common Dalby Faults
The dalby lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine Dalby 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 Dalby repair.
Dalby lift shows Out of Service and won't accept calls
Engineer onlyThe Dalby commercial lift has fault-locked itself and the car display reads Out of Service.
Most people arriving at Dalby troubleshooting pages describe the problem in roughly these words. A Dalby 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 Dalby 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 Dalby 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 Dalby 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 Dalby servicing catches most of these early, and good Dalby maintenance notes shorten the engineer's diagnosis.
Dalby lift doors keep reopening and won't leave the floor
Engineer onlyThe Dalby car doors close, then reopen without any command and the lift does not depart.
Before you phone anyone about a Dalby repair, work through the description below. Repeating door-reopen cycles on a Dalby lift are a safety-edge or light-curtain fault.
The full-height infra-red curtain across the Dalby 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 Dalby 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 Dalby 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 Dalby servicing question rather than a one-off Dalby repair; recurring symptoms usually trace back to a missed maintenance interval.
Dalby lift stops slightly above or below the floor
Engineer onlyThe Dalby car floor comes to rest 10–40 mm above or below the landing sill.
This symptom accounts for a steady share of the Dalby repair enquiries we see each month.
Levelling errors on a Dalby 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 Dalby 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 Dalby fittings, the car sinking below the floor after a load steps out is a valve or seal issue. Building staff should not try any Dalby isolator reset.
The correct action is to sign the car out of service on the Dalby lift log and log the fault with the manufacturer's callout time in mind.
Keep the Dalby maintenance paperwork with the lift. Whoever attends the Dalby repair will want to see when the last service was done.
Dalby display shows a warning message
Engineer onlyA status message or warning indicator has appeared on the Dalby car operating panel display.
This is one of the most common reasons UK owners look up Dalby troubleshooting in the first place.
Any message on the Dalby 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 Dalby 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 Dalby 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 Dalby 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 Dalby servicing schedule, so check the date of your last Dalby maintenance visit while the paperwork is out.
Dalby lift alarm rings but the intercom is silent
Engineer onlyPassengers press the alarm on the Dalby car and get no voice response.
Of every Dalby troubleshooting question sent to us. This symptom is among the most frequent. Since 2018 every new commercial passenger lift in the UK, including Dalby 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 Dalby lift and nobody answers, the emergency line is either not configured, the SIM in the Dalby auto-dialler has expired, or the telecoms line into the machine room is down.
The auto-dialler unit on a Dalby 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 Dalby maintenance is always cheaper than reactive Dalby repair.
The log is what turns a vague complaint into a booked servicing job.
Dalby lift ride is rough or noisy
Engineer onlyThe Dalby car judders, vibrates or is markedly noisier than usual in travel.
Read this through before booking any Dalby repair. The answer is often simpler than it looks.
A Dalby 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 Dalby traction machine.
Building staff should not diagnose any of these.
The intent of noting the change is to raise it with the Dalby 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 Dalby 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 Dalby repair.
A plain description helps far more than a guessed diagnosis.
Dalby repair
A genuine Dalby 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 Dalby 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 Dalby 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 Dalby equipment.
Grinding — likely causes on a Dalby 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 Dalby 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 Dalby Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Dalby 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 Dalby lift holds a solid red light, it is telling you a safety circuit is broken or a fault has been stored.
Nine times in ten it is something in plain sight rather than a hidden electrical failure. 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
The safety chain marks the end of owner checks on a Dalby lift. Contact your service provider — or send the form below — if you spot:
- Repeated faulting only minutes after a reset.
- Burning smells, smoke, or visible cable or control damage.
- Water in the pit, machine space or inside the car.
- A car beyond its normal travel or not sitting level at the floor.
- Doors, gates or interlocks operating inconsistently.
- 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.
Dalby servicing
Dalby servicing intervals are set by the installer and by how hard the commercial elevator works: a domestic unit used a few times a day is not on the same schedule as one in constant use. If you have inherited the equipment with a property, ask the incoming provider for the last service sheet before agreeing a plan.
Keep every service sheet. A dated history of Dalby 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.

Dalby maintenance
Treat Dalby maintenance as a short weekly routine: confirm the commercial elevator responds normally from every landing, confirm the alarm is audible where somebody would hear it, and confirm the charge indicator behaves as it always has. Anything outside that pattern goes to your provider rather than into a toolbox.
Nothing in owner-level Dalby 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 Dalby lift covered by this page?
Dalby is a to confirm manufacturer active in To confirm. The ranges most often met in the UK are To confirm.
The fault-finding below is written around the behaviour those Dalby 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 Dalby reads "No established lift maker of this name found". This can change whose manual actually applies to your machine.
Where does a Dalby lift show its fault code?
On Dalby equipment the sign is described as: Unconfirmed. Codes are not standardised between makers, or even between board generations within Dalby, 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 Dalby controller or any panel to chase it.
Which Dalby problem comes up most often?
The fault this page opens with is "Dalby lift shows Out of Service and won't accept calls". The Dalby commercial lift has fault-locked itself and the car display reads Out of Service.
The next most reported Dalby symptom is "Dalby 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 Dalby source for fault information?
The authoritative reference for this brand is the To confirm. Dalby 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 Dalby document that covers your fitting.
Our own coverage of Dalby is currently rated "Index note", so treat this page as an orientation and the manufacturer's document as the authority.
Who is the dutyholder for a Dalby lift under LOLER?
For a Dalby 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 Dalby maintenance contractor usually coordinates the inspection. However, the duty does not transfer to them.
