why is my drawer dishwasher knocking during a wash?
a spoon or other utensil projecting through a drawer dishwasher rack can meet the turning spray arm and cause knocking. check the load before assuming that an internal motor has failed.
stop the wash normally, let the drawer cool and switch off before moving items. look underneath the rack for projecting utensils and check that the base rack or folding insert sits properly. use the exact model's rack instructions rather than forcing it into position.
the linked filter-and-spray-arm guide is relevant if accessible removable parts also need cleaning or refitting. it covers different filter-plate releases and leaves the rotor in place; the older DS605/DD605 arrangement is not a universal drawer layout.
if knocking continues with the spray path clear and parts properly seated, arrange service. do not run the drawer with required parts missing or swap rotors as a diagnostic test. leakage, excess retained water or sharp debris also means stop.
possible causes
- a utensil reaching into the spray-arm path
- a rack or insert sitting out of position
