We got a portable ultra wash kenmoore dishwasher from craiglist, we cannot get the water to come out of the sprayer, any ideas how to get it going?

Did it come with the Kenmore specific faucet adapter?

If it didn't, you should be able to order one from Sears.

Its actually pretty easy unscrew sides or flip up and find water inlet will have to hoses (portable) coming out with 4 screws take out screws then pull oarange-ish colored inside out and clean screen and then take needle and clean out all holes put back together then you are done
