I’ve added an attachment of the printout for your viewing pleasure.

Looking at those codes... You really should look at the first and last occurrences, in addition to the total count. Some of them could be really old, some could have occurred multiple times within a short burst (meaning it was really just a single event). As for the water in fuel, if the truck sat for a while condensation could have built up in the tank and/or the water separator. Change filter, maybe try a fuel treatment and watch to see if it occurs again.

Those aftertreatment codes however, mainly the regen too frequent and the high ash load. Could be your DOC/DPF is old and worn out and not working as it should. Maybe drop the cans, get them cleaned and flow tested. If the problem persists (it could take a few weeks to reoccur after the cleaning) then either the cans are shot and need replacement or you are burning too much oil and that's why you have some much ash building up in the DPF. Either way, your problem will probably continue to get worse until you start getting to the shutdown stage. That's exactly the situation I went through.

How long have you had the truck? What's you oil and coolant consumption like? Did you, or whoever hooked up insite, look at the Aftertreament History? That would tell a lot about the DPF health. That code for regening too frequently, that's not a good sign.

Also, I see that's a cm2250. Have you, or do you have proof that someone else, rebuilt the head or replaced the fuel pump? If you don't know about it, go to the main page of this site and do a search for "cm2250 fuel pump". At 600,000mi it's well past due.
