Product review (4 stars): They have to be changed on a pretty much yearly basis
the only part to fix this notorious whirlpool problem the plastic white drive wears down quickly, making whirlpool a household word synonymous with "never buy whirlpool". They have to be changed on a pretty much yearly basis. Learn to do it yourself, takes about 5 screws out on the basin area. No need to pull the washer out. Should take less than an hour. Plenty of U tube videos. symptoms, everything seems to work as it should, but the dishes don't get clean and water doesn't reach top rack. If it gets clogged enough, water won't reach the bottem ones either. the white plastic drive on it grinds down from a pointy 4 teeth, to a shorter flatter 4 teeth that don't reach out far enough to reach the black gear on the motor.
