Dishwasher not cleaning the bottom rack

The lower spray arm spins under the bottom rack, driven by water forced through it by the wash pump. Jets along the arm blast water up through the dishes. If the jets block with food or scale, the arm cracks, or the hub wears so it wobbles or stops spinning, the bottom rack comes out dirty or gritty. You may also hear knocking as a loose arm hits the rack. Clean the jets and filters first, then replace the arm if it is cracked, warped or won't turn freely.

Changing the lower spray arm

Turn the dishwasher off and pull out the bottom rack. Most lower arms lift straight off their hub or release by undoing a centre nut or cap, so check how yours is held before pulling hard. Clean the hub and filters while the arm is off. Fit the new arm, turn it by hand to confirm it spins freely without touching the rack, then run a rinse.

Questions about this part

How do I clean blocked spray arm jets?

Take the arm off and rinse it under a tap, then clear each jet with a toothpick. Shake out any loose debris from inside. If jets keep blocking, the filter may be damaged or not seated properly. Replace the arm if it is cracked or warped.
