[Discussion]Finding correlations on a complex datasets with WEKA

I had been learning machine learn since last week so I am quite fairly new to the data mining/machine learning field. I downloaded WEKA yesterday and gone through two classes of WekaMOOC but still couldn't learn what I want.

Here is the thing. I have a dataset that contains lots of variables like temperature, waterflow, voltage and such.

The problem here is that the waterflow level decreased over time, everytime it dropped to 1.0 litre/minute, the machine stops. My job here is to find correlations on a complex datasets and find variables that is link to the waterflow level. I know a bit of R Studio but will be glad if anyone can tell me how to do it on WEKA.

This is just some random practice my professor gave me because I told him I want to learn more about machine learning. I hope you people can bring me insights of machine learning. Please enlighten me!
