Abstract: A search for the $K^{+} \to \pi^{0}\pi^{0}\pi^{0}e^+\nu$ decay is performed by the OKA collaboration. The search is based on $3.65 \times 10^9$ $K^+$ decays. No signal is observed. The upper limit set is BR$(K^{+} \to \pi^{0}\pi^{0}\pi^{0}e^+\nu) < 5.4\times 10^{-8} ~ 90\,\%$ CL, 65 times lower than the one currently listed by PDG.
