4055790499 Genuine Lower Spray Arm for Electrolux Dishwashers KEE27200IW, Bottom Wash Arm

Part 4055790499 is the genuine lower spray arm from the Electrolux dishwasher range, listed for model KEE27200IW. It sits under the bottom basket and spins on the water pressure from the wash pump, spraying up through the lower rack. If dishes on the bottom are coming out dirty, or the arm is cracked or won't spin, this is the part to replace.

Dirty dishes on the bottom rack? Check the lower spray arm

Water from the wash pump is forced into the lower spray arm and out through small jets along its blades. The force of that water spins the arm so the spray sweeps the whole bottom rack. If a jet blocks with food, glass or seeds, or the arm cracks, warps or loses its bearing, the spin slows or stops. Typical signs are dishes left with food stuck on them, gritty residue on glassware, a knocking sound as the arm catches on an item, or an arm that wobbles on its hub.

Swapping the lower spray arm

Turn the dishwasher off at the wall and pull out the bottom basket. Depending on the model, the arm either lifts straight off its hub or is held by a nut or clip in the centre, so note how yours comes off. Fit the new arm, spin it by hand to make sure nothing catches, and run a short cycle to check it turns.
