Acorn 180 Curved
With the Acorn 180 Curved Stairlift, there’s no longer any need to compromise your independence and struggle with the stairs in your home. You can be proud to join the thousands of people all over the world who enjoy independent living at home, thanks to the Acorn 180.
The Acorn 180 has a built-in soft start and stop facility, and you can be sure that your stairlift
is always ready for use thanks to the integral rechargeable battery pack, even in
the event of a mains power failure.
The Acorn 180 fits practically any curved staircase, and its slim, attractive rail fits to your stairs, so there’s no damage to your home. It has been designed to include a wide variety of comfort and safety features, to provide you with many years
of safe and reliable enjoyment of your stairlift. To ensure your lift is simple and effortless to operate, the Acorn 180 has also been designed with ease of use and comfort in mind.
The unique self-levelling transport system
moves the stairlift along the low profile rail and automatically adjusts the speed and level of the seat when moving round corners. The stairlift’s electronic programming ensures optimum performance at all times, providing a comfortable ride
When not in use, the Acorn 180 can be folded away; its slim profile and unique inside parking ability ensures that the staircase is not obstructed, allowing other members of the household to use the stairs as normal.

Acorn Stairlifts Fault Codes
Acorn 180 (Previously Acorn 80) Fault Codes (Curved Stairlift) 2013 Onwards
Prior to Acorn Stairlifts buying Bison, they had their own range of codes which are listed below. These older lifts are known to be problematic and a lot of the time the issue may require a board replacement as the older boards were only good for 5 or 6 reprogrammes.
| Code | Description (Scroll Right To Read More) |
|---|---|
| A1 | Not On Charge Point – This code means the stairlift is normal, however isn’t charging. Ensure lift is on charge point and power supply switched on. |
| A2 | Lift Moving Up – The lift is travelling in the upwards direction by means of it’s toggle switch. |
| A3 | Lift Moving Down – The lift is travelling in the down direction by means of it’s toggle switch. |
| A4 | Lift Moving Up – The lift is travelling in the upwards direction by means of it’s remote controls. |
| A5 | Lift Moving Down – The lift is travelling in the down direction by means of it’s remote controls. |
| A9 | Hinge Operating – The lift is waiting on the hinge to operate. |
| C1 | Battery Charging – The batteries are charging with the higher number meaning a fuller state of charge. |
| C2 | Charger Volts Too Low – Voltage is too low from the charge point, possibly wiring issue or faulty charger. |
| C3 | Charger Volts Too High– Voltage is too high from the charge point, possibly a faulty charger. |
| C4 | Batteries Charged – The lift is on a charge point and the batteries have fully charged. |
| C5 | No Battery – The charger is connected but no batteries have been detected. |
| E1 | Footrest Downside Activated – Check to see there’s no obstructions on either side of the footrest. |
| E2 | Footrest Upside Activated – Check to see there’s no obstructions on either side of the footrest. |
| E3 | Footrest Underplate Activated – Check to see there’s no obstructions underneath the footrest. |
| E4 | Carriage Downside Activated – Check to see there’s no obstructions on either side of the carriage / drive unit. |
| E5 | Carriage Upside Activated – Check to see there’s no obstructions on either side of the carriage / drive unit. |
| E6 | Seat Turned – The seat is in it’s turned position, turn the seat back to normal for lift to work. |
| E7 | Battery Low – Drive the stairlift down to the lower charge point to recharge batteries. |
| E8 | Heat Sink Over Temperature – High temperature detected on main PCB board, power down for a period to cool down, if no success replace PCB. |
| E9 | Encoder Fault – There’s a fault with the drive or levelling encoder. Check encoder is working and replace if no success. |
| F1 | Relay Fault – Turn the lift off and on again, if this doesn’t work then the main PCB board may need replacing. |
| F2 | Brake Fault – Most likely due to low batteries, let lift charge and if not resolved contact engineer as brake may be faulty. |
| F3 | Motor Over Current – Either the lift is being used past it’s weight limit or the motor is faulty. |
| F4 | Tilt Motor Fault – Tilt motor demand too high, check for obstructions on both sides of lift. |
| F5 | Battery Flat – Drive the lift down to it’s charge point and leave to charge for 1-2 hours, may show an E7 code which will clear itself when recharged. |
| F6 | Final Limit Overrun – The stairlift has gone past it’s intended stop, handwind the stairlift away from the stop a few inches to reset. |
| F7 | Overspeed Governor Fault – The OSG has tripped in the stairlift. Service engineer required to reset this due to the complexities involved. |
| F8 | Tilt Limit Switch – The lift has gone beyond it’s expected angle, possible that the rail has sunken to a negative degree of angle. |
| F9 | OSG Pulse Not Present – The lift isn’t detecting OSG rotation when travelling, clean the front face of the rail and failing that replace the OSG. |
| H1 | Safety Switch Shorting Or Multiple Fault – There’s either a safety switch grounding with the chassis or there’s multiple faults on the safety loop. |
| H2 | Levelling System Over Reacting – There’s a fault with the drive or levelling encoder, contact us if the issue persists for a free quote. |
| H3 | Hinge Communication Fault – Check there’s still power switched on from the mains. |
| H4 | Secondary Processor Fault U2 – Switch off the lift and back on again, if unresolved contact us for a repair. |
| H5 | Memory Store Not Responding – Switch off the lift and back on again, if unresolved replace PCB or contact us for a repair. |
| H6 | Hinge End Limits Not Found – Check for obstructions with the powered hinge to ensure it can move up or down freely. |
| H7 | Over-tilt Fault – The stairlift has over tilted possibly due to a faulty encoder. If unresolved contact us for a repair. |
| H8 | Voltage Supply Limits Reached – Switch off the lift and back on again, if unresolved contact us for a repair. |
| H9 | Accelerometer Fault – Switch off the lift and back on again, if unresolved contact us for a repair. |
| J1 | Level Difference – Due to the level position changing, the lift needs to be reset by driving the lift to the top charge point. |
| J2 | Drive Position Difference – Due to the drive position changing, the lift needs to be reset by driving the lift to the top charge point. |
| J3 | Self Levelling Safety Mode – Drive the lift to the top charge point to clear this code. |
| J4 | Program Out Of Range – Possible encoder fault or reprogram needed. If unresolved contact us for a repair. |
| J5 | Program Fault – The program is not stored or may be corrupted. |
| J6 | Program Position Overrun – Drive the stairlift to the top charge point to reset. |
| J8 | Hinge Activation Point To Close – The lift is set within 80mm of the parking charge point, move the lift further away on programming. |
| U1 | Set Hand Mode (Program Mode) |
| U2 | Left Hand Mode Selected (Program Mode) |
