Using the MX4700/LA844 for some work and all at once the bucket quits going up or down -- like it's stuck. It tilts forward/back normally.
Checked the fluid, and all the hoses. Don't see anything abnormal.
Any suggestions for troubleshooting?

Pull the cover off the top of the control valve and check the linkage to see if the spool valve is moving.
If the loader arms are down, disconnect the quick connects and reconnect them.

Check the position of any remote valves and the 3pt control. If they are not in neutral they will block the loader valve.

Swap the up-down hoses with the tilt-dump hoses and re-evaluate. Does it change and now you know if in the loader or the joystick. Does it seem like it is deadheading in either direction? Just be careful and possibly lock the bucket up or slowly loose a line to get the bucket on the ground. Sounds like a pioneer coupling has failed/loosened in my experience.

Thanks everyone. I took all four quick disconnects off and put back on. Had to remove some Fittings to relieve pressure. reconnected Everything and now it works. Really don’t know why.
