Mine makes suds in the washer w/out soap. First noticed suds coming from drainpipe yesterday. Started expirementing. 2 clean hand towels suds like a bubble bath. Plain water has suds, not as much with a few towels but suds. Did all the things posted. Vinegar. Several loads with nothing, wasting gallons of hot water. Ran hot water in every sink and tub in the house. Got up this am, washed the two hand towels that have been washed 10 times at least SUDS at the end of wash cycle, no soap of any kind. Every things is new. Remod laundry room 4 months ago. Plummer replaced everything. Appliance Co hooked everything up. All new. Everything was fine until yesterday. I'd like to say our pipe that comes thru the roof (squirrels) but it drains fine except a large load. We had foaming at the down pipe entrance. That said. The suds are made in the washer, plain water, new commercial speed queen top load. Top of the line. Lived here 20 years no issues. Eve put water in a blender to see if we had water issues.
I've done everything mentioned.
