HELP - engine symbol with kW and downward arrow inside accompanied by STOP

[missydel]

Hi, really need some help diagnosing this problem. I have a 2021 New Holland PowerStar 75. The STOP symbol is on along with the engine symbol that has the letters kW and a downward arrow in the middle. I can not find anywhere what this means or how to fix it / get the symbols to go away. The symbol came on out of nowhere and the tractor has been running completely fine ever since. I did notice that the coolant reservoir tank was empty and added some coolant to it, the radiator was practically full and I topped that off as well but that did not fix the problem. I also noticed that the tube connecting the two doesn't have any fluid in it so I thought I might have to bleed some air but I also can't figure out where the bleed screws are or how to do this (if this is the problem, I have no idea) - please help asap, we just had a fire and need to sell the tractor to keep us afloat but want to fix this problem before selling it in order to get the max price. Thanks in advance! Attached is a photo of the dash.

I assume that means "power down". Either voluntarily or it will handle it for you. You should have codes somewhere.

I had a couple of NH tractors up until about 3 years ago and got rid of both. I think the STOP is indicating low oil pressure, but like a lot of the warning lights it could also mean something else. In any case, a STOP light usually means something critical. On the KW light, I think that's going to be tied to the reduced power mode. Sorry I'm not more certain but that's what I got and I gave the manuals to the new owners when I sold them. Your manual should have something on it or, as @workinonit said, you should have some codes set. Retrieving the codes may require someone with the diagnostic equipment to do so.

yes I believe it means the engine is reducing power for some reason, but I also can't figure out how to find the codes

I did not get a manual from the previous owner & I can not find that specific symbol anywhere in any online manuals. I'm now trying to figure out how to view the code in the setup menu on the led screen. If you or anyone else knows how to do this I greatly appreciate any and all help.

I don't think you can view the codes from the menu. You're going to need some diagnostic equipment to read/reset the codes. There may be some aftermarket tools for it, but not that I'm aware. If you do find something the chances are it's going to be cost prohibitive for a one-time use. I think you're going to need to take it to a dealer or maybe check around for some independent mechanics that work on New Holland. I'm fortunate that I have a couple of independent mechanics locally that have the diagnostic tools and usually are a lot cheaper than a dealer but there doesn't seem to be a lot of those guys around. Maybe someone else here has a better suggestion.

The Workmaster 75 service manual has a section on how to run diagnostics. If the PowerStars have anything like it for diagnostics you will need the manual. It is not something that is easily done.

If you really want to you can access all codes and diagnostics, just be prepared;
New Holland Agriculture Self Repair | MyCNHi Store

Often you can find PDF copies of the service manuals for a reasonable price. I have had decent luck 4 out 5 have been good.

Back to the used tractor and no manual fiasco. I would NEVER buy ANY used tractor without at least the owners manuals and record of maintenance. In my book, no manual or service notations mean a no sale and I've been there and did that in the past I might add.

Not sure why owners like to hoard manuals, manuals that they have no use for anyway.

I remembered I had made an account & registered the tractor online with new holland so I have access to the manual & maintenance history there. Still don't know what the error code means & now I have another problem of not being able to access the settings menu on the screen. I tried the directions in the attached photo as well as the directions on all the other pages in order to try to gain access to the settings menu and nothing works.
