Question on a Kubota B2400 Loader Valve

[Dwarner]

I recently picked up a Kubota B2400 with a LA351 loader. My problem is when the loader valve is in the float position the 3 point stops working all the hydraulic fluid is sent back to the tank. With the loader valve in any other position the 3 point works correctly. The loader valve has ports marked IN and OUT for hydraulic fluid. A, B,C, D for the hydraulic cylinders and for power beyond the port is marked DFP which is an identification I have never seen before. Could this valve be missing an internal power beyond plug?
The id tag on the valve LM305B and under that is 1625AG

I have no idea on your problem but hopefully @TheOldHokie will be able to help you out when he is back. Others may be able to help you also

That sound like normal (yet not ideal) operation.
It's very common for loader valves to override normal operations under certain situations.

Thats not "normal". Float is typically

A,B->T
P->PB.

Thats certainly true on a LA525. Can you operate the bucket when the boom spool is in float?

I dont see a PB port in your pictures.
