I have a Hitachi zaxis 75us-5a. The tilt bucket has started riding all the way up one way and the pump not disengaging, it then goes all the way up the other way and doesn’t disengage and just repeats this. The buttons on the joystick have become very stiff. This is still happening even after taking off tilt bucket and shutting off taps where hoses attach. Any advice would be muchly appreciated Cheers
Welcome to HEF wagsnz . Sounds like you have a messed up joystick handle or wiring. You could unplug the wiring at the handle disconnect or at the solenoid valve to prove it.
