764570143 Genuine Dishwasher Lower Spray Arm, Bottom Wash Arm for Smeg Dishwashers DWAFI6D15PO DWAFI6D15T DWAU615DX3

Dishes on the bottom rack coming out dirty? 764570143 is the genuine Smeg lower spray arm, the rotating arm under the bottom basket that sprays water up through the load. It's listed for Smeg DWAFI6D15PO, DWAFI6D15T and DWAU615DX3 dishwashers. A cracked or warped arm loses pressure and spins poorly, so a new 764570143 can make a real difference to wash results.

How a worn lower spray arm affects your Smeg dishwasher

Water pumped from the sump is forced out through small jets along the arm, and the push from those jets is what makes it spin. If the arm is split, has a broken end, or its hub is worn, water escapes in the wrong places and the arm slows or stops. You'll notice food left on plates and pots in the lower rack, a gritty film on glasses, or a knocking sound as the arm catches. Blocked jets give similar results, so clean them first, then replace the arm if it's damaged.

Changing the lower spray arm

Turn the dishwasher off at the wall and slide out the bottom basket. Lower arms either lift straight off their hub or release by turning a retaining nut, so check how yours is held before applying force. Clear any debris from the hub and filter area, fit the new arm and spin it by hand to make sure it turns freely without touching the basket.

Questions about this part

Can I just clean my old spray arm instead?

If it's only blocked, yes. Rinse it, clear each jet with a toothpick and check it spins freely. If the arm is cracked, warped or wobbles on its hub, cleaning won't fix it, and replacing it with 764570143 is the better option.
