A dirty dishwasher filter can leave food debris, odors, and poor cleaning results. If your dishwasher has a manual filter, clean it when the machine is cool and remove it according to the manufacturer’s instructions.
Find the correct filter
It is often below the lower spray arm, but designs vary. Check the manual before twisting or forcing parts that may not be user-removable.
Remove debris and rinse
Empty trapped food and rinse the filter. Use a soft brush on greasy residue without damaging the mesh.
Clean the accessible filter well
Remove debris from the accessible filter well without pushing objects toward the pump. Avoid sharp tools near seals or impellers.
Lock it back in place before running
A poorly seated filter can allow debris to circulate or interfere with washing. Confirm it is locked in place according to the manufacturer’s markings. If the filter fills with debris again very quickly, review loading habits. Dishes that block spray arms or large amounts of solid food can increase what reaches the filter and reduce cleaning performance.
