Understanding Stairlift Error Codes on Acorn Stairlifts

A stairlift displaying an error code

When a stairlift stops working, it can cause stress and disruption—especially when it's a vital part of your daily mobility. Fortunately, most Acorn stairlifts are equipped with a diagnostic display that shows a stairlift error code, helping to identify the issue quickly.

Below is a complete guide to Acorn stairlift error codes, what each one means, and when it’s best to call a professional technician like BAW Stairlifts. For safety reasons, we’ve only provided self-help guidance where appropriate—technical faults should always be handled by a qualified engineer. Simply click on the "CALL TECHNICIAN" to be directed to our contact page where we can assist you if your stairlift is displaying a code that requires an qualified engineer.

When to Act — and When to Call

Some codes—like A1, E1–E4, and E5—can be resolved by the user by removing obstructions or repositioning the seat. Others, especially those in the F, H, J, P, U, and L ranges, involve technical diagnostics and should only be handled by a trained stairlift engineer.

At BAW Stairlifts, we’re committed to safe, prompt service to keep your stairlift running smoothly.
