Common Commercial Elevators Problems

The commercial elevators faults UK owners search for most often — triage guidance in plain English, with links through to the specific brand pages and matching symptom guides.

Commercial lift shows out of service and won't accept calls

A commercial elevator that reads "out of service" on the car or landing display has fault-locked itself — the controller has detected an issue it will not clear without an engineer reset. Owners of an Otis, KONE or Schindler unit should note the exact wording, the time of day, whether the car is at a floor and level, and call the service line. Do not attempt to reset the mains or open the machine room — a fault-locked commercial lift is telling you something safety-critical has tripped.

Doors keep reopening and the lift won't leave the floor

Door reopening cycles are a light-curtain, safety-edge or door operator fault. On Mitsubishi Electric, Hitachi and Toshiba Elevator passenger cars the light curtain runs the full car opening height and any dust, sticker or shopping trolley in the beam will make the doors bounce open. Wipe the vertical rails of the door opening, remove any obvious obstruction, and if the fault persists log a call. Do not force the doors closed — the safety edge is the primary passenger protection.

Lift stops slightly above or below the floor

Levelling errors — the car floor coming to rest 10–40mm above or below the landing sill — are a trip hazard and must be reported the same day. On modern TK Elevator and Orona installations the drive re-levels automatically after loading; when levelling degrades it points to the encoder, the drive or brake wear. On older Otis and KONE hydraulic lifts, sinking below the floor after a load steps out is a valve or seal issue.

Alarm bell rings and the intercom is silent

Since 2018 every new commercial passenger lift in the UK has been required to have a two-way voice communication from the car to a 24/7 monitored line. When passengers press the alarm and no voice answers, the emergency line is either not configured, the SIM has expired, or the telecoms line into the machine room is down. On Doppler, Canny Elevator and Broad Group installations the auto-dialler unit lives in the machine room; a monthly test call is a compliance requirement, and building owners are responsible for keeping the line paid.

Safe to Check Yourself vs Engineer-Only

If your lift sits in a workplace or managed building, see our LOLER thorough examination guide for the 6- and 12-month statutory inspection rules that sit alongside repair.

Frequently Asked Questions

Who is responsible for a commercial 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, keeping the reports and acting on any defects. The service contractor typically arranges the LOLER inspection as part of the maintenance schedule.

How quickly should a commercial lift call-out be answered?

Most UK commercial lift 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 contract — response times are the single biggest lever on tenant experience.

Can building maintenance staff enter the lift machine room?

Only competent lift engineers may work in a lift machine room. Building staff may enter to read the log, retrieve keys or accompany an engineer, but any physical work on lift equipment is engineer-only.

The lift keeps going out of service in the same way. What should we ask the contractor?

Ask for the fault log from the controller for the last 30 days, ask which specific 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.
