Poor washing on the top rack of a Westinghouse dishwasher

The upper spray arm sits under the top basket and spins as water is pumped through it, washing the cups, glasses and bowls above. If a nozzle blocks with food, seeds or limescale, or the arm cracks or warps, water pressure leaks away and the arm turns slowly or stops. You will see food left on top rack items, a greasy film on glasses, or water spraying sideways instead of up. Clean the nozzles first with a toothpick and rinse the arm under the tap. If it is still cracked, bent or won't spin freely, replace it.

Fitting the upper spray arm

Turn the dishwasher off at the wall. Pull the top basket out and look at how the arm is held, usually by a nut, clip or bayonet fitting on its hub. Remove it carefully without forcing the plastic, and check the water feed it connects to is clear. Fit the new arm, spin it by hand to make sure it clears the basket and the items above, and run a test load.

Questions about this part

Is this the same arm as the lower one?

No. Upper and lower spray arms are different shapes and fit different mountings. This listing is the upper arm only, part 4055762159, so check it is the top arm you need before ordering.
