Hi all I recently got a Kubota B3030 with a cab has a bucket, snowblower. 7' back blade and a brush hog attachments that came with it. Going over it getting things ready for winter. both front and rear wipers work just fine but the front and rear washer does not work. I unplugged the connector from the pump and there is no power when I depress either switch front or rear. Anyone have any suggestions? Thank you

Without looking at a wiring diagram and assuming this machine doesn't suffer from "creative wiring", it might just be a fuse or a bad switches. Two switches going bad at once is odd however. They may have gone out one at a time and never replaced before you bought the machine.
Suggest using a test light or multimeter and seeing if you have power at the switches. If you do, have power there, it would seem the switches are bad. But could also be wiring to the pumps being cut, corroded or something.
There also could be relays operated by the switches that failed.

1st would be to get a copy of the WSM and /or wiring diagram ! Hopefully it's SIMPLE wiring and NOTHING is 'computer controlled' !!!
Since both don't work, it sounds like either a blown fuse or an open ground. Unlikely BOTH switches and BOTH pumps have failed. There 'should' be a separate ground wire from cab to tractor not just using mounting bolts as the ground connection.
Curious.. does everything else electrical work in the cab ? If so , then probably not a ground issue,so check all the fuses. I'd think 2 pumps might be a 3,5,7 amp fuse, maybe a 10. Nothing higher . need to see the wiring diagram though.

I checked the fuses under the hood, all are good. Have a bunch so I changed them all out anyway, just to make sure they were "fresh" the original ones looked original and old. Seem the wipers and washer are on he same fuse. I will take the dash apart and check the switch and check the switch on the back glass. there is only one pump. Looks like it will "wash' both the front and back at the same time. I don't know how old the tractor is, it came with the house I bought. It came with a LA403 bucket loader, a Land Pride RCR1860 brush hog, a Land Pride FDR1660 finish mower, and a Kubota B2782 snowblower. I sold the finish mower and bought a King Cutter 7' back blade as I already have a 60" zero turn mower. My first tractor so I am learning.
You said: " there is only one pump. Looks like it will "wash' both the front and back at the same time. "
Strange there are two switches. Anxious to see what you find out.

It can have one pump and spray the front and rear independently…been like that for years in automotive world.

Yep… they reverse polarity the pump to make it happen. Hoses come off opposite sides of the impeller.

I also have a 7' King Cutter back blade........wanna buy another one?
THEN,...... I bought a 6' Everything Attachments, 6 Way Deluxe Scrape Blade.
What a difference!
Wanna buy another KK 7' back blade....cheap?
If it is an older tractor, then possibly the rubber parts in the washer system have hardened and are not working. A common problem in old cars.
Update but first thank you all I took the dash apart pulled the connecter plug off the switch and yes there is power there put it back on and the squirter pump works took it back off cleaned the spades with some emery paper and put it all back together and everything works as it should. Filled the reservoir with rain x pink and the switch for the front squirts front and rear the switch for the rear only controls the wiper. I guess Kubota figures if your going to clean the front you might as well clean the back too lol. Again thank you everyone for your input I love free repairs. Installed some LED lights. I am now ready for winter

Sweet! '
You have a B3030HSDCC-A B3030 cab cold winter version with the rear wiper,rear window defroster and 60 amp upgrade.
I just couldn't pay the extra $300 when we bought it new in 2007.
Great machine that will treat you well.
