my loader will only move up regardless of using the up or down position. What is the problem?

have you checked all the connections? IE on the control value quick disconnects?
any kinked hoses?
how many hours?

I have checked connections, kinks, etc. Pressure builds up on lower right line,[female] not in the control valve. I have bled it off several times with the same results. I even bled the line and lowered the bucket and no matter which control I use [up or down] the bucket will rise.

have you tried to swap the those hoses with the bucket control hoses?

If it works then-- It is likely to be a control valve problem..

Have you moved any hoses on the loader valve? You may have the hoses mixed up.

my problem was the quick connect above the line that was loading up. It was not allowing the fluid to complete its flow.
