We present a search for the decay X⁡(3872) → π+⁢π-⁢π0 in the (772 ±11) ×106 Y⁡(4⁢S)→B⁢$$\overline{B}$$ data sample collected at the Belle detector, where the X⁡(3872) is produced in B± → K±X⁢⁡(3872) and B0→K$$^{0}_{S}$$X(3872) decays. We do not observe a signal, and set 90% credible upper limits for two different models of the decay processes: if the decay products are distributed uniformly in phase space, $$\mathscr{B}$$⁡(X⁡(3872) → π+⁢π-⁢π0)<1.3%, and if M⁡(π+⁢π-) is concentrated near the mass of the D0⁢$$\overline{D}$$0 pair in the process X⁡(3872) → D0⁢$$\overline{D}$$*0 + c.c. → D0⁢$$\overline{D}$$0 ⁢π0 → π+⁢π-π0, $$\mathscr{B}$$⁡⁡(X⁡(3872) → π+⁢π-⁢π0)<1.2×10-3.
