Safety Warnings

Ensure the dishwasher is turned off and disconnected from power before performing maintenance.
Be cautious of sharp food debris or broken glass that may have collected in the filter area.

Dish brush — Nylon bristle

Sponge — Non-abrasive

Dish soap — Mild liquid(Small amount)

Warm water — Tap water(As needed)

Clear out all dishes and the bottom rack of the dishwasher to gain full access to the tub floor.

Tip: Check for any large food scraps left behind in the tub first.

Locate the filter assembly at the bottom of the dishwasher tub, typically located underneath the lower rack.

Tip: The filter is usually a cylindrical plastic component.

Twist the filter locking mechanism counter-clockwise to unlock it from the dishwasher housing.

Tip: If it feels stuck, apply gentle pressure; do not force it to avoid breaking the plastic tabs.

Lift the filter assembly straight up and out of the dishwasher tub.

Tip: Have a sink or bowl ready to catch any trapped water.

Rinse the filter under warm running water to remove loose debris and food particles.

Tip: Use a sprayer for more effective removal of stuck-on grime.

Apply a small amount of mild dish soap to the filter and scrub gently with a nylon brush or sponge.

Tip: Focus on the mesh screen where grease and fine particles accumulate.

Rinse the filter thoroughly with warm water until all soap suds and debris are gone.

Tip: Ensure no soap residue remains, as this can cause excessive foaming in the machine.

Wipe out the filter housing area inside the dishwasher tub with a damp sponge to remove any remaining sediment.

Tip: Check the sump area for any stray seeds or glass fragments.

Reinsert the filter into the housing and twist it clockwise until it locks firmly into place.

Tip: A loose filter can allow debris to enter the pump, potentially causing a malfunction.

Run a short rinse cycle to ensure the filter is seated correctly and to clear any remaining debris from the system.

Tip: Perform this maintenance monthly for optimal machine performance.

Always clean the filter if you notice a smell of old food or if water is not draining properly.
Avoid using abrasive steel wool on the filter mesh to prevent tearing the screen.
