NOT 

CHARGING 

(4 BEEPS)

The stairlift is not properly parked 

on a charging station. The stairlift

WARNING 

(6 BEEPS)

The sensors of the stairlift 

encountered a problem 

while driving. Please go to 

Troubleshooting at the next page 

to attempt to clear the problem. 

Contact your certified UP dealer if 

this does not solve the problem. 

NOTE: The sound of the audible warning device is the 

same for warnings and errors. Some errors can only be 

cleared by a certified UP Stairlift dealer.

TROUBLESHOOTING

The stairlift has multiple sensors which check the 

condition of the stairlift. In case of a mechanical 

or electronic failure, the stairlift will go into safe 

position to prevent possible damage to the stairlift 

or injury.

LEVEL SENSOR WARNING AND ERROR
The stairlift has multiple sensors which detects 

the angle of the stairlift. When driving on a bend, 

leaning to one side could trigger the sensors which 

stops the stairlift from moving. 
Solution
Release the joystick and be sure to sit straight on the 

chair. Wait a few seconds and attempt to drive again.

OBSTRUCTION SENSORS

The stairlift is fitted with multiple obstruction 

sensors, which, upon collision, prevent the stairlift 

from moving any further. It could be that one of 

the obstruction sensors is triggered and stops the 

stairlift from moving.
Solution
Try to see if one of the obstruction sensors of the 

stairlift has been triggered (white covers).

POWER SUPPLY
The stairlift has two 12 volt batteries which could 

be low after too many consecutive rides. When 

the batteries are low, the stairlift may be able to 

drive for a short amount of time and stop after 

the power is gone. The stairlift is programmed to 

drive downstairs and may not be able to drive up 

anymore. 
Solution
Try to drive back to the charging station when 

driving down.

If the stairlift does not have enough power to drive 

anymore, please contact a certified UP Stairlift 

dealer. 

Never switch off the stairlift while the stairlift is 
driving. This could lead to the stairlift getting stuck 

or damaged.
