How to Install Dishwasher Circulation Pump Mesh Filter ADQ32598202 in a LG Dishwasher

Quick answer: Pull the lower rack, lift off the lower spray arm and twist out the cylindrical filter. Lift the old mesh filter out of the sump recess, clean the recess, then drop ADQ32598202 in with its tabs in the slots so it sits flat. Refit the cylinder filter and spray arm and run a rinse.

The circulation pump mesh filter ADQ32598202 is the flat mesh screen that sits in the sump at the bottom of the tub in your LG dishwasher, directly under the lower spray arm. It is the last barrier between the wash water and the circulation pump impeller, catching food scraps and glass fragments that get past the cylinder filter. When the mesh tears, warps or clogs beyond cleaning, debris reaches the pump, the wash pressure drops and dishes come out gritty. LG lists this filter for models such as LSDF995ST, LSD795ST4, LDF6920WW and LDS4821BB.

This is an easy job that takes about ten minutes and needs no tools. The filter lifts out once the spray arm and cylinder filter are removed, and the new one drops into the same recess. The only things to get right are cleaning the recess so the mesh sits flat, and locking the cylinder filter back in place afterward so the seal is complete.

⚠️ Safety First
  • Let the dishwasher cool before reaching into the sump; water left in it can be very hot.
  • Wear gloves, as glass shards often collect exactly where this filter sits.
  • Do not run the dishwasher with the mesh filter out; debris will go straight into the pump.
  • Keep small filter parts away from children.

Tools and Parts You Need

  • Flashlight to see into the sump recess
  • Soft brush for the recess and the cylinder filter
  • Towel to soak up water in the sump
  • Work gloves in case there is broken glass in the sump
  • Mild dish soap or vinegar for scale on the filter seat

Step-by-Step Installation

  1. Empty and cool the dishwasher Remove dishes and wait until the tub is cool. Open the door fully.
  2. Remove the lower rack and spray arm Roll the lower rack out and set it aside. Lift the lower spray arm off its hub, turning its collar first if your model has one.
  3. Twist out the cylinder filter Turn the cylindrical filter in the centre of the sump in the unlock direction marked on it and lift it out. Rinse it under the tap and set it aside.
  4. Lift out the old mesh filter The flat mesh filter is now exposed in the sump recess. Lift it out by its edge or tab. Note which way its tabs face.
  5. Clean the recess Remove any debris from the sump opening and brush scale off the ledge the mesh sits on. Check the pump inlet for anything that got past the old filter.
  6. Seat ADQ32598202 Drop the new mesh filter into the recess with its tabs in the slots and the mesh facing the same way as the old one. Press it gently so it sits flat all around with no edge lifted.
  7. Refit the cylinder filter and arm Set the cylinder filter into the centre of the mesh and turn it to the lock position until it stops. Snap or lock the spray arm back onto its hub and spin it by hand.
  8. Refit the rack and test Roll the lower rack in, close the door and run a short rinse cycle. Listen for normal pump sound and check that water drains fully at the end.

Fit Checks Before You Call the Job Done

  • Mesh filter sits flat in the recess with no lifted edge
  • Tabs are seated in their slots and the filter does not shift when pushed
  • Cylinder filter turns to the locked position and stops firmly
  • Spray arm spins freely over the reinstalled filter
  • Rinse cycle runs with normal pump sound and full drain

Common Mistakes to Avoid

Leaving debris under the mesh A seed or shard under the filter lifts one edge and lets debris bypass it. Clean the recess before the new filter goes in.

Not locking the cylinder filter An unlocked cylinder filter lets water bypass both filters and the pump takes in grit. Turn it until it stops.

Forcing the mesh in the wrong way The tabs only fit one way. If it will not sit flat, lift it and turn it rather than pressing harder.

Reusing a torn mesh A small tear is enough to let glass into the pump. Replace the mesh rather than trimming or patching it.

Troubleshooting After Installation

Gritty dishes after the new filter Check that the cylinder filter is locked and the mesh is flat. Clean the spray arm nozzles, which may be holding debris from before the swap.

Loud pump or grinding sound Something reached the impeller before the filter was replaced. Remove the filters and check the pump inlet for glass or hard debris.

Water left in the sump after the cycle This is a drain issue, not the mesh. Check the drain hose and the drain pump area for a blockage.

Filter will not sit flat Debris or scale is under it. Remove it, clean the ledge and reseat with the tabs in the slots.

Care Tips After the Repair

  • Rinse the cylinder filter and check the mesh every couple of weeks.
  • Scrape plates before loading so the mesh does not clog quickly.
  • Clean up broken glass from the sump immediately so it cannot tear the mesh.
