why are dishes still dirty after my dishwasher finishes?
food left on dishes can result from a blocked filter, obstructed spray arm or nested items that keep wash water out. start with loading and permitted removable-part cleaning rather than assuming a pump has failed.
after the cycle finishes, switch off and let the tub cool. separate touching dishes and utensils, check that baskets travel fully in and gently check spray-arm clearance. use a programme suitable for the load.
the linked filter-cleaning guide covers releasing, rinsing and securely locking the complete filter. watch for broken glass and do not operate the dishwasher with filters missing. the separate loading-and-spray-arm guide explains how to rinse an arm only where the model permits removal; attachments vary.
if washing remains poor after correct loading and cleaning, arrange assessment. a cracked spray arm, damaged rack support or sharp debris you cannot handle safely needs help. these checks do not establish which internal component requires replacement.
possible causes
- food blocking the filter
- a spray arm or its holes being obstructed
- dishes nested together or a cycle unsuitable for the load
