Today we received a call for a stairlift repair in Exeter. As we had a stairlift service to do first in Exmouth this worked out nicely. It was on an old Acorn Superglide 120 straight stairlift which was showing an ‘E’ error code. This was the Acorn fault code for a brake issue.
Acorn Brake Fault Code
From experience I knew this stairlift repair in Exeter was unlikely to be an issue with the brake assembly. For this reason the first thing I checked was the battery voltage. Sure enough they were reading over 13V and below 5Ah. I replaced the batteries and the code cleared.
Can Low Batteries Cause Circuit Faults?
What actually happened here was that the batteries didn’t have enough power to release the brake. As the brake is electro mechanical it requires power to release so that in its resting state it is on as a safety feature. As the brake couldn’t release, the stairlift processor thinks that there is a problem with it. This is the same with a lot of safety circuits on a stairlift.
Another Happy Customer
We only use high quality batteries so this stairlift shouldn’t need another set for 3-5 years. This South West stairlift repair in Exeter only took around 20 minutes to repair but the customer was dependent on it and was thrilled that we were able to carry out a stairlift repair so promptly.
