Bottom rack dishes coming out dirty?

Water pumped up from the sump drives the lower spray arm round, and its jets do the heavy cleaning on the bottom basket. When an arm cracks, the pressure escapes through the split instead of the nozzles, so it turns slowly or not at all. Blocked jets, a worn hub or a warped arm that drags on the filter give the same result, leaving food on the lower plates, gritty residue and spots. A cracked arm may also knock as it catches tall items.

Changing the spray arm

Turn the dishwasher off and pull out the lower basket. Most lower arms lift straight off their hub or are held by a clip or screw cap, so check how yours is fixed before pulling. Clean the hub and filter area while the arm is off. Fit the new arm, spin it by hand to check it turns freely and clears the basket, then run a rinse.

Questions about this part

Can I clean the old arm instead?

If it's only blocked, yes. Rinse it and clear each jet with a toothpick. If the arm is cracked, warped or wobbles on its hub, cleaning won't fix it and a new arm is the answer.
