Claim:
A dishwasher for reducing squealing as a result of pivoting a door with respect to a body of a dishwasher, the dishwasher comprising: a door pivotably attached to a body via a hinge assembly comprising a hinge bracket coupled to the door, and a counterbalance assembly coupled between the body and the hinge bracket for facilitating pivoting of the door, wherein the counterbalance assembly comprises: a biasing member coupled to the body; a flexible element serially engaged with the biasing member and having a coupling member serially engaged therewith opposite the biasing member; a non-metallic bushing fixed to the hinge bracket and configured to engage the coupling member such that the non-metallic bushing is disposed therebetween, wherein the non-metallic bushing is independent of the coupling member such that the coupling member is configured to pivot with respect to the hinge bracket and the non-metallic bushing as the door pivots and the non-metallic bushing is configured to reduce squealing between the coupling member and the hinge bracket; and a guide member coupled to the body and including a fixed arcuate member defining a first guide track, and a pulley rotatable about an axis and defining a second guide track, wherein the flexible element is at least partially wrapped about each of the fixed arcuate member and the pulley so as to serially engage the first and second guide tracks.
