The information below is diagnostic and indicative. Repairs, calibrations and clearing of fault codes are carried out by a qualified service technician, according to the manual for the specific serial number of the machine. A machine with an active fault code must not be used until the cause has been removed.
Genie S-60 technical data useful for service
Weight and dimensions decide how the machine is transported to a workshop, while the tyres, battery and drive decide which parts are needed. When you report a service job, please also give the serial number from the rating plate.

Most common Genie S-60 faults
Boom will not raise or extend
- Likely cause
- Discharged battery, an active fault code, basket overload or a fault of the boom angle or length sensor.
- Diagnosis / how to fix it
- Check the power supply, read the fault code and verify the load in the basket.
Machine will not drive, or drives only at creep speed
- Likely cause
- Joystick out of range or not centred, an open footswitch, or the drive limitation that is active while the boom is raised.
- Diagnosis / how to fix it
- Centre the joystick, check the footswitch and lower the boom to the stowed (transport) position.
Tilt alarm
- Likely cause
- Working on a slope, or a damaged or uncalibrated tilt sensor.
- Diagnosis / how to fix it
- Level the machine; calibration or replacement of the sensor at a service centre.
Basket overload (overload / load sense)
- Likely cause
- Capacity exceeded or a basket load sensor out of calibration.
- Diagnosis / how to fix it
- Reduce the load; calibration of the weighing system at a service centre.
Boom sagging or descending slowly
- Likely cause
- Worn cylinder seals, a holding valve fault or air in the system; moisture can make valves stick.
- Diagnosis / how to fix it
- Inspect the cylinders, valves and hydraulic oil; repair at a service centre.
Loss of CAN communication between modules
- Likely cause
- Chafed bus cable, corroded connectors or a damaged module (basket, chassis, power module).
- Diagnosis / how to fix it
- Check the bus and the connectors and read the fault code with a service analyser.
Combustion engine: will not start, stalls, overheats
- Likely cause
- Glow plugs or relay, throttle position sensor (TPS), temperature and oil pressure sensors, fuel system.
- Diagnosis / how to fix it
- Read the engine codes and check the sensors and wiring.
Basket will not come down
- Likely cause
- No power to the lowering valves or an electrical fault.
- Diagnosis / how to fix it
- Use the emergency lowering (the valve on the chassis), then have the electrics diagnosed at a service centre.
Genie S-60 error codes: 21 codes explained
Genie uses the on-board GSDS diagnostic system (Genie SmartLink). Codes are divided into DTC (a detected device or circuit fault) and OIC (an unusual operating condition, e.g. overload). On scissor lifts, DTCs are marked with a letter for the system type and a number; on boom lifts (Z and S series) there is also a two-digit flash code (red LED = source, yellow LED = type).
Below you see the code and the original manufacturer's message. Open a code for the likely cause, what you can check yourself and when to call service.
