Spray arms direct water onto dishes; debris and scale can obstruct the jets. Bosch advises checking the arms, rinsing them and securely refitting them. Detachment methods vary by model, so never force any component.

Your try-it-at-home checklist

0 / 6 done

Stop the cycle, let the interior cool and remove the lower rack; locate the model's instructions.
Gently check that the spray arms can rotate without hitting tall dishes or baskets; inspect the small jets for debris and scale.
Only detach arms if the manual permits it. Some upper arms unscrew while lower arms lift out; do not force unfamiliar fittings.
Rinse removed arms under lukewarm running water. If the maker permits, gently clear openings with a wooden toothpick and rinse again.
Refit each arm as instructed, check that it rotates freely by hand and replace the racks.
Try a normal wash. If unusual noise, leakage or poor rotation persists, stop using the appliance and seek service; do not open pumps or electrical parts.
