Washer Will Sometimes Not Drain Whirlpool Washing Machine

Chosen Solution

I have a WTW8900BCO washer that sometimes will not drain. Each time I will pull the drain pump and reinstall and it works fine for a few days before not draining again. The drain hoses are clear. The unit is 4 years old. What do you think?

have you tried changing the belt ? if it is stretched you’re most likely to get this problem.
