The $K_S \to 3 \pi^0$ decay is a pure CP violating process which, assumingCPT invariance, allows one to investigate direct CP violation. This decay hasnot been observed so far, and the best upper limit on the branching ratio$BR(K_S to 3\pi^0) < 1.2 \cdot 10^{-7}$ is two orders of magnitude larger thanpredictions based on the Standard Model: $BR(K_S \to 3\pi^0) \sim 2 \cdot10^{-9}$. In this article we present the search for the $K_S \to 3\pi^0$ decayperformed with the KLOE detector operating at the DAFNE {\Phi}-factory at theFrascati Laboratory. We describe the analysis techniques used in the backgroundrejection and signal events selection as well as the evaluation of almost fivetimes lower upper limit on the $K_S \to 3\pi^0$ branching ratio. We discussshortly also the perspectives for a new measurement using the KLOE-2 apparatusequipped with a new inner tracker and the calorimeters at low theta angle.
