Older dishwashers often had a grinder that chopped up food and sent it down the drain. Many newer Frigidaire dishwashers use a manual-clean filter instead, which runs quieter and uses less energy but depends on the owner to rinse it. When that step gets skipped, cleaning performance slides gradually enough that people blame detergent or the machine.
How Often
A reasonable starting point is once a month for an average household. Clean it more often if you rarely scrape plates, run the dishwasher daily, or notice odors. Your owner's manual gives the interval for your specific model.
Cleaning the Filter
- Let the dishwasher cool after the last cycle, and switch it off.
- Remove the lower rack.
- Twist and lift out the filter assembly as the manual shows. Most designs have a cylindrical fine filter and a flat mesh plate.
- Rinse under warm water and scrub gently with a soft brush. Avoid wire brushes or scouring pads that can tear the mesh.
- Wipe out any debris in the sump opening with a damp cloth.
- Reinstall until the filter locks in place. An unlocked filter lets debris reach the pump.
Checking the Spray Arms
Spin each spray arm by hand; it should turn freely. Look into the small spray holes for seeds, bits of paper or hard-water scale. If your manual shows the arms as removable, take them off and clear holes with a wooden toothpick, then rinse and reinstall. Do not force an arm that is not designed to come off.
Deal With Hard Water
White film on glassware and a chalky tub suggest hard water. Use rinse aid consistently and consider a dishwasher cleaner product following its label. Avoid mixing cleaning products.
If the dishwasher still leaves food on dishes after the filter and spray arms are clean, the wash pump or water heating may be the issue. Our dishwasher repair technicians can check it.
