The disclosure provides a flushing process for removing polymer fouling from a reactor including a gas distributor proximal to the bottom thereof and an internal condenser proximal to the top thereof, the method including, for a first flushing time period, injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the internal condenser to induce an upward movement of flushing solvent, the withdrawn flushing solvent containing a first polymer content. After the first flushing time period is complete, for a second flushing time period, the process includes injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the gas distributor to induce a downward movement of flushing solvent, the withdrawn flushing solvent containing a second polymer content.
