This machine comes up on the U. S. Sears site as a Dryer, so the model number will not cross reference correctly.

I think it is a front load machine made by Whirlpool, and flying blindly here I can only say to try replacing the water pressure switch as some of the Whirlpool front loaders use that switch as a control for the suds problem.

Diagnosing your problem is a difficult process, at least for me thanks to the Whirlpool folks.

Good luck.
