If you’ve ever owned or cared for a stairlift, you’ll know how invaluable it is for maintaining independence and mobility at home, but like any piece of equipment, stairlifts can sometimes encounter issues — often indicated by error or diagnostic codes. These codes may seem confusing at first, but they’re actually designed to help pinpoint what’s wrong, whether it’s something simple you can resolve yourself or a sign that professional servicing is needed. In this blog post, we’ll walk through the most common stairlift error and diagnostic codes, what they mean, and how to respond. Whether you’re here out of curiosity or trying to troubleshoot a real problem, this guide will give you a clearer understanding of what your stairlift is trying to tell you.
