I have a 10-year-old Whirlpool Cabrio washer Model # WTW7600XW0. When I wash a load it goes through most of the cycle but then it stops, displays "Sd", and starts beeping. I looked in the manual and it says "Sd" means Excessive Suds. I can't see any suds in the tub and the clothes I wrang out did not feel soapy. The clothes were sopping wet, but it seemed as though the tub had drained, but failed to spin.
I used the proper amount of HE detergent. I ran it through a "Quick Rinse and Spin" with the same results.
Any ideas as to what could cause this?
