We have had quite a few complaints like yours, ( especially with new MayTag washers) where the washer pump is too powerful for a 1 1/2" trap and stand pipe. What size is yours?
I have a solution that I've never had a complaint on and one that I had to use on my washer. You close off the stand pipe the washer connects to with a compression fitting,(see image) or I caulked the hose in with rags and sealed it with duct tape. This makes a water tight connection between the washer and the stand piipe. Nothing can leak out or overflow and the force from the pump will send the discharge out into the main drain. While there is some back pressure involved there will not be enough to damage the washer pump. Outside of oversizing the washer trap and standpipe this is about the only solution that I know that works. Good luck, Tom

I kind of have a problem with sealing a stand pipe.
My story.

Many years ago, bought a new washer (from Sears). New washer kept going out of balance. Two or three times each spin cycle. Called for service. After second service call failed to correct the problem I called again, got someone in management and threatened to sit it in the middle of their showroom floor. Third repairman came out (with I think, instructions to fix washer, what ever it took). I helped. We tried everything. Tried several new snubbers. Nothing worked. The drain hose just reached the stand pipe and I had duct taped it in to make sure wouldn't just pop out. We were having trouble getting behind washer to see what was happening so repairman ran out to truck and got an extension. When we put extension on and remove duct tape, the washer began working just fine.
It seems sealing the drain causes a syphon action which pulled ALL the water out of the washer. A small amount of water is supposed to remain in tub so that clothes can move around at the start of the spin cycle to balance themselves out.
A couple of years ago doing handy man repairs for client. She complained of washer frequently going out of balance. I looked at washer, found drain hose duct taped just like I had done. Remove duct tape. No more complaints of washer going out of balance.
