Customer Questions and Answers for Washer Drain Pump Assembly by Whirlpool

Mr. Hunt, You could have something ( needle,pin, paper clip) in the pump or a worn out thrust bearing assembly. Those are the two most common "noise " issues with that style unit. You would want to slide the unit away from the wall, remove the front panel, " Insert a flat bladed tool(putty knife) between the top panel and front panel approximately 4 inches in from the front corners, press in on the blade and lift up on the front corners, to disengage the spring clips. Once to top is up and braced, remove the two 5/16 in. screws holding the front panel to the cabinet cross brace, tilt the top of the front panel out until the alignment pins are cleared, the lift up on the front panel to remove. Raise and block up the front of the washer, and remove the belt, turn the pump drive pulley and feel for a smooth even rotation of the pulley shaft assembly. if there's a "ratchetting " or clicking feel when you turn it, theres something in the pump . If the pump is operational, remove the plastic cap off the center of the transmission pulley, remove the "C" clip and remove the cam and pulley assemblt from the shaft and check for distorted or damaged parts. Thanks and Good Luck.
