I have a k2 machine 30,000 hours having intermittent flow inlet error. I checked all the possible causes and basically replaced almost all hydraulic components, I'll say the hydraulic system is new. I'm at lost , the error keeps popping out. I noticed after letting it ran and get the system warmed up , the error will go away and passes test but when you run it the following day it error will show again.

Would you mind listing all components you have replaced in the hydraulics? Did you perform a back to back before and after new install of the parts? A back to back will be the best thing to do at this time to further determine hydraulics or electronics.
Check the boards in the cage & check dist board for burns. Once the parts you replaced or checked are listed, that will help us direct you better. I don't want to give you the general check rundowns b/c I'm sure you've been through it too.

Thanks for responding. I replaced all the valves ( 29,41,30,39,24,25,26) , balance chamber assy with valves , float swtich, dearation and flow pump with heads. cfs 9 and 10, air separator assy. rebuilt inlet water regulator . rebuilts loading and flow pressure regulators. How do you perform back to back ? sorry my first time hearing it.

The float switch is not lowering the way it should, or else the machine senses it that way. Usually this is caused by a problem with the deaeration pump/motor or an obstruction downstream, but you have replaced almost everything.
I suppose it could be something electrical, and as the machine warms up, the error goes away.
In a back to back, you hook up the machines in such a way that the electronics of one controls the hydraulics of the other. You want to see if the problem follows the card cage or the hydraulics. It can get confusing. Guest2day has a point. I am out of ideas.

Thanks Dave, My focus was on the hydraulic side and then got frustrated with all the parts and the countless hours I spent replacing them so I let the machine untouched for now. I try doing the back to back and go from there.

in the tips and tricks section of this forum is a flow error work sheet. Follow that to find the issue.

Thanks for listing what you did as well. Fingers crossed the back to back narrows it down to one of the two.
Double check that your valves are connected to the appropriate spot on the dist board and vice-versa on each valve is connected correctly. Make sure valve #24 & 26 connectors aren't swapped with eacother. If I remember correctly valve 26's wiring pins are soldered differently from all the rest of the valve connections.
If you do end up determining that it's the hydraulics.. go back to checking the BC assembly. Eventhough it's new, check all valves, open them up to check for rusting and make sure there are no obstructions in the valve housing. I've come across very small pieces of broken plastic/debris inside those valve housings. Also, I see you rebuilt the loading valve- if you use diasafe filters it needs to be the strong spring.

Not common but I've seen a diasafe filter cause this. And please ensure your pump heads aren't installed backwards. Input should be lower than the output.

be advised when 25k hours is reached the y and t connectors can flake off and cause an obstruction they should be replaced at 25k hours

I've had an issue similar to this, it turned out the deaeration orifice was intermittently getting blocked by some debris.

Mine was caused by the Balancing Chamber, crack in the diaphragm.

also check your act/sensor cables

Back when we had some high hour Ks, we had a few hydro blocks start breaking down inside. We replaced it, problem went away.
