Rocket thrust washing machine drain hose
It is hard to actually answer your question without actually asking more questions (see comments section of original question). But despite that you may want to look into installing a drain hose restraint that helps to keep the hose from jetting its way out of the drain drop pipe. This is often a wire assembly that attaches to the hose and the drain pipe. Some ties a short piece of chain is included.

The restraint device can correct for extra high jet strength coming out of the hose but it will not be able to correct for any possible restriction in the down pipe.
