Stair lift fault codes, wiring & service programming for engineers. Offline.
Read full description
PerliStairs is a stairlift fault code guide for engineers: every stair lift error code, the wiring, the test points and the service-mode programming for four stairlift models, bundled inside the app so it opens in a stairwell with no signal.
It is written for the person who services the lift. A second, deliberately plain mode for the person who owns one helps you describe what yours is doing to the engineer you are about to ring. That mode does not diagnose anything and is not a substitute for an engineer — it says so before it says anything else.
WHICH LIFTS
- Handicare / Minivator MS125
- Bespoke Infinity
- Access BDD Flow2A
- Access BDD Flow X
PerliStairs is an independent field guide. Handicare, Minivator, Bespoke and Access BDD are their owners' trademarks; none of them is affiliated with this app or endorses it.
FOR THE STAIRLIFT ENGINEER
- A quick-reference card for each lift — the screen the app opens on.
- Search every code and every procedure across all four lifts at once.
- Fault-code tables with a plain-English line for every code.
- Connector pin-outs, test voltages and fuses as tables.
- Service-mode programming step by step, with the traps called out.
- A parts index: tap a component named in the text to see where it sits on the lift.
- Guided assessment: which lift, what it is doing, then narrow it down. Every outcome cites the manufacturer source it came from.
- It is not a copy of any manual. For full pages, drawings and photographs, use the manufacturer's own documentation.
FOR SOMEONE WHOSE STAIRLIFT HAS STOPPED
- Pick what the lift is doing from a list written in ordinary words.
- Read the code off the display two ways: photograph it and let the phone read it, or tap the character that matches yours on a drawn seven-segment display.
- Owner-safe checks only — the charge point, the armrests, the emergency stop, the mains switch. Nothing in this mode asks anyone to open a cover, touch anything electrical or move the lift by hand.
- Put it together as a short report — the code, the checks you made, a photo or a video — and send it to your engineer from the share sheet.
- If the lift is behaving unexpectedly, the app's answer is to stop using it and call your engineer.
READING THE CODE OFF A PHOTO
The recogniser runs on the phone and the photo is never sent anywhere. It only offers codes that exist on the lift you picked, and labels them "most likely", "likely" or "possible" — words, not a percentage, because it is a suggestion to check against the table, not an answer.
WHAT IT COSTS
PerliStairs is free, with Google AdMob ads: a banner at the foot of each main screen, and occasionally a full-screen ad after you finish and send a fault report. No ad on a model page, the assessment, a diagram or mid-report. A one-time "Remove ads" purchase turns them off; no subscription. Consent is asked where the law requires it.
WITH NO SIGNAL
The whole guide ships inside the app — the code tables, the procedures and the owner's checks. Everything except Ask works with the phone in flight mode.
ASK
Ask is the one screen that needs a connection. Type a question in ordinary words and an AI assistant answers it from the bundled guide. Your question, and the slice of the guide it is answered from, are sent to our server. Apart from the ads and signing in, nothing else in the app talks to a server.
PRIVACY
- You sign in with your Google account, once, with a connection. Your email address is used for sign-in only, and there is no password to create.
- Your photos, your videos and your notes stay on the phone until you choose to share them yourself.
- Optional usage counts are off unless you turn them on. They never include what you searched for, what you asked, or any photo.
- No location, no contacts, no microphone. The app does not ask for camera access: taking a photo hands you to the phone's own camera app.
