LX3310, 85 hours. The Water in Fuel light (with alarm) came on. I immediately stopped and (not real sure what the alarm was), checked all fluids, saw no water in the separator but drained it anyway, and started the tractor up. Alarm was cleared but came back on after about 15 minutes of use. Now will not clear... completely drained the cup (did not remove it), and refilled. Started, and the alarm came in within seconds. Any suggestions? Dealer is no help... 50 miles away and service department doesn't answer the phone or return messages or emails.

I searched and could not find where the sensor was located... thought maybe loose wire?

Looking in the brochure the sensor should be on the filter housing.
I found the brochure to be less than helpful... I could find no sensor on the fuel filter or water separator. I am planning on changing the fuel filter and removing/cleaning the entire water separator.

Thanks for the input, though! Now I know where to focus my search tomorrow...

Just looked on Messicks website parts diagram and couldn’t find anything for the water in fuel sensor. There should be someone here with an LX3310 that can chime in. Just give it time for them to respond

Does it mention anything in the owners manual? Did you buy it new?
Bought it new. Owner's manual is not in my immediate possession (I moved...it's hiding in a box somewhere) but I downloaded one from Kubota and can find nothing helpful. However, everything I have read seems to point to a minor amount of water stuck on the sensor, so tomorrow I plan on disassembling and cleaning all visible components, changing the fuel filter, loading up with new fuel and a water treatment additive and idle it for a while and see what happens...

Try https://kubotabooks.com/ to see if they have your shop manual. The site is safe. Lots of us have used it.

If they don't have your manual, try Kubota directly. It won't be cheap, but it will be right.

To my knowledge shop manual is not available for (pirated) download. I bought mine from Messicks.

There is lots of info about water sensor in Operators Manual, which is available for free from Kubota online.

next stop is WSM:
WSM- TRACTOR LX2610, LX2610SU, LX3310 AP

After completely disassembling the fuel system (lines, separator, filter) and cleaning them all with clean kerosene and blowing them out with compressed air and adding a diesel fuel conditioner and new fuel, the light went out after about ten minutes of running under a load. Worked all day without a recurrence. My neighbor thinks I may have had a bubble of water stuck to the sensor. No way of knowing for sure, but hopefully the problem has been solved. Thanks to all for the input!

I would like to have a model that has an alarm on it, so I don't have to keep checking it for water. My BX22 went 20 years without problems, and I only changed the filter once when it clogged after 500 +- hours. Twenty years ago it was a lot easier to get under the tractor than it is today, so a better filter that will alert me to a problem is now higher on my list of needed items. My tractor is now mostly relegated to snow removal duties, and winter is the worse time to have a tractor requiring service.

No, never did. No wires going into or near the cup or the fuel filter. I know its there somewhere... But after seven hours of heavy use, the alarm has not returned, so I guess I got it fixed!
Here is the location of the water in the fuel sensor.

It mystifies me that many folks will not go to the trouble or expense to get a shop manual (cost $100 to $250 for paper copy from dealer) cheaper if you buy electronic copy from Kubota website. The owner's manuals are free there. The cost of making a mistake on the common rail systems is high, 10 k or worse. The paper copies are huge, copyrighted, and if you use them once or twice a year over 10 years or more, only cost you $10 or 25 per year to have the nice figures like whitetiger posts at your fingertips.

No offense to the OP in this thread, it is a common thing on the forum. Someone will spend 30k or more for a new tractor and only want free manuals.

For what the machines cost, Kubota could well afford to include one with every purchase. When I purchased my Vermeer wood chipper, the selling dealer gave me the workshop manual on a thumb drive. When I asked if a paper copy was available, the salesman handed the thumb drive to someone to print it out in color. It took almost 3/4 of an hour to print it on their high-speed color printer and was more than a ream of paper. Unlike Kubota, Vermeer sells factory direct to the customer, and the service is the best that you could ever want. The manual is clear, concise, and loaded with detailed pictures.

I think one rationale for not including a paper copy of the shop manual unless and until it is ordered, is that they are revised occasionally. The pages are dated. A lot of people never look at the owner's manual, much less 3 or 4 hundred pages of technical stuff. It would be wasted money to give them a shop manual.
