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.
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.
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.
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.
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.
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.
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 installations, the car sinking below the floor after a load steps out is a valve or seal issue. Building staff should not attempt 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 response time in mind.
Dalby display shows a warning message
Engineer onlyA status message or warning indicator has appeared on the Dalby car operating panel display.
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 indicate a component drifting toward failure and should be treated as urgent.
Dalby lift alarm rings but the intercom is silent
Engineer onlyPassengers press the alarm on the Dalby car and get no voice response.
Since 2018 every new commercial passenger lift in the UK, including Dalby installations, has been required 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 requires a monthly test call — this is a building-owner compliance requirement 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.
Dalby lift ride is rough or noisy
Engineer onlyThe Dalby car judders, vibrates or is markedly noisier than usual in travel.
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.
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, and how long the sound has been present. Do not enter the shaft, the pit or the machine room, and do not attempt 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
A steady red indicator on a Dalby passenger lift is a fault the controller is deliberately advertising. Building-management duty is to note exactly what the display shows — colour, position, any number or letter — quote it verbatim to the service company, and put the landing out of use with a barrier until an engineer resets it. Do not enter the machine room, do not turn Fireman's or Independent service on or off in an attempt to clear the code, and do not cycle the mains isolator. Any red indicator on a commercial lift is engineer scope from first sight.
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 Dalby 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.
- 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.

Frequently Asked Questions
Who is responsible for a Dalby lift under LOLER?
The dutyholder — usually the building owner or their appointed managing agent — is responsible for arranging a six-monthly thorough examination by a competent person on any Dalby passenger or goods lift, keeping the reports, and acting on any defects. The Dalby service contractor typically arranges the LOLER inspection as part of the maintenance schedule.
How quickly should a Dalby call-out be answered?
Most UK Dalby maintenance contracts commit to a four-hour response for out-of-service calls in normal hours and a one-hour response for passenger entrapments. Check your specific Dalby contract — response times are the single biggest lever on tenant experience.
Can building maintenance staff enter the Dalby machine room?
Only competent lift engineers may work in a Dalby machine room. Building staff may enter to read the log, retrieve keys, or accompany an engineer, but any physical work on Dalby equipment is engineer-only.
The Dalby lift keeps going out of service in the same way. What should we ask the contractor?
Ask for the fault log from the Dalby controller for the last 30 days, ask which specific Dalby fault flag has been raised each time, and ask what the root cause is — not just what was reset. Repeated resets without a root-cause fix indicate a component nearing end of life.
