1118952108 Genuine Lower Satellite Spray Arm 459.2mm for Electrolux Dishwashers, Bottom Spray Arm, Use with Support 1118940020

1118952108 is Electrolux's genuine lower spray arm in the satellite style, measuring 459.2mm long. A satellite arm carries a second, smaller arm that spins at the end of the main arm, giving the bottom rack wider and more varied spray coverage than a single straight arm. The lower spray arm support it sits on is a separate part, 1118940020. Check the length and the number on your old arm before ordering.

Dishes dirty on the bottom rack? Check the lower spray arm

The lower arm spins on water pressure from the wash pump, and its nozzles spray up through the bottom rack. If the arm cracks, warps or its nozzles clog with food or glass, pressure leaks away and the arm turns slowly or stops. The satellite section can also seize, leaving parts of the rack poorly cleaned. Dishes coming out gritty or with food still stuck on the bottom rack, a rattling or clunking noise, or an arm that wobbles on its mount are all signs to check it. Clear the nozzles first, and replace the arm if it's damaged or still won't spin freely.

Fitting the lower spray arm

Turn the dishwasher off and take out the bottom basket. Lift or unclip the old arm from its support. Check the support for wear or cracks, and replace it with 1118940020 if needed. Seat the new arm, then spin it by hand to make sure it turns freely and clears the filter and the bottom of the rack.

Questions about this part

Do I need the support 1118940020 as well?

Only if your existing support is cracked, worn or loose. The arm sits on the support, so a damaged one can make even a new arm wobble or stop turning. Replacing both at once saves a second job if the support is near the end of its life.
