Amazone UX3200 special low pressure

[Jim t]

I have the above but it’s putting on 23% less than what is on the screen , it has clean filters and no top hat filters. The pressure goes down to 1.2 bar when spraying. I can increase the pressure when it’s in manual but when I go back to auto the pressure/ rate decrease. Any suggestions please?

We have the exact same sprayer
Had this problem before and it turned out to be O rings in the main distribution chest, quick cheap and easy to sort

We have a uf1801 and had the same problem, as wold-topper said we changed the little o rings on the valve chest and sorted the problem.

As suggested it is those O ring seals which are allowing the chemical to return to tank. Mine has just had the same fault fixed.
