I hope this helps you :-)!

press and hold the lock button down for 3 seconds and it should unlock. if it does't then the electronic control is malfunctioning.

have you ever tried unplug it and wait 20 secs and then plug it in again? I hope it works, God bless

F28 is a communication error which usually means there is a connection that has come loose.Check the wires on the control board.

Hi.

Error LR means Locked Rotor.

Either the motor is faulty, there is a wiring problem, or the control assembly is faulty.

Try tripping the circuit breaker to reset the machine, if code comes back a technician must have a look at the motor.

If you mean a jet aircraft, that is normal. Front loaders achieve amazing spin rates.

u cant it means locked rotor u need a new motor

buy a quality front loader
