How to Install Dishwasher Fine Filter 00441905 in a Bosch Dishwasher
Quick answer: Slide out the lower rack, twist the cylinder filter counterclockwise and lift it out, then lift the flat mesh from the sump floor. Clean the recess, drop in fine filter 00441905 so its cutout sits around the drain opening, reinsert the cylinder and twist clockwise until it locks.
The fine filter 00441905 is the flat mesh screen that lies in the floor of the sump at the bottom of many Bosch dishwashers, directly under the cylindrical microfilter. Its job is to catch food particles and grit before wash water reaches the circulation pump and the drain, so the pump stays clear and the drain path does not clog. When the mesh tears, warps or wears a hole, debris slips into the pump and you start seeing gritty film on glasses, longer cycles and gurgling drain noises.
Replacing it is one of the simplest jobs on a Bosch dishwasher: no wiring, no plumbing and usually no tools, because the filter set is designed to lift out for routine cleaning. This guide applies to models such as SHE43P02UC64, SHE55P06UC59 and SHU3305UC11 among the 645 models in our fitment list. Match your model number from the label on the door edge before ordering, since Bosch used several similar filter designs and a near match will not seat.

- Run or cancel the cycle so the dishwasher pumps out, leaving the sump nearly empty instead of full of dirty water.
- Let the tub cool if a cycle just finished; the heater and lower spray arm can still be hot enough to burn.
- Wear gloves if the old filter holds sharp fragments such as broken glass, bone chips or fruit pits.
- Keep the cylinder filter, mesh and spray arm away from small children while the parts are out of the machine.
Tools and Parts You Need
- Replacement fine filter 00441905
- Soft brush or old toothbrush for cleaning the sump
- Dish soap and warm water
- Microfiber towel or paper towels
- Flashlight to inspect the sump and pump inlet
- Small cup or sponge to remove standing water
Step-by-Step Installation
- Empty and open the tub Open the door fully and slide the lower rack all the way out of the dishwasher. Set it aside so you have a clear view of the tub floor and the filter housing in the center.
- Check the lower spray arm On most models the spray arm stays put. If it overhangs the filter housing and blocks your grip, lift it straight up off its hub and set it aside.
- Remove the cylinder filter Grip the cylindrical microfilter in the center of the sump, twist it counterclockwise about a quarter turn until the arrow reaches the unlocked mark, and lift it straight out.
- Lift out the old fine filter The flat mesh sits underneath. Lift it by its edge and pull it up out of the sump recess. Note how the cutout in the mesh lines up around the drain opening so you can orient the new one the same way.
- Clean the sump Scoop out standing water and wipe the sump floor. Use the brush to clear debris from the pump inlet and from the groove where the mesh rests so the new filter can lie perfectly flat.
- Seat the new fine filter Lower fine filter 00441905 into the recess so its cutout wraps around the drain opening and its lip sits flush with the tub floor. Press lightly around the edge to confirm it is level and does not rock.
- Lock the cylinder filter Insert the cylinder filter through the hole in the mesh, push it down and twist clockwise until it stops and the arrows align. It should feel firm and should not lift when you tug it.
- Reassemble and test Reinstall the spray arm if you removed it, slide the lower rack back in, and run a short rinse cycle. Listen for normal draining and open the door afterward to confirm the mesh stayed flat.
Fit Checks Before You Call the Job Done
- The mesh lies completely flat, with no edge sitting proud of the tub floor.
- The cutout in the mesh frames the drain opening without covering it.
- The cylinder filter passes through the mesh, seats fully and locks with a firm quarter twist.
- The lower spray arm spins freely by hand without rubbing on the filter assembly.
- The lower rack rolls in and out without catching on the filter housing.
Common Mistakes to Avoid
Forcing the cylinder filter If the cylinder will not twist in easily, the mesh is not seated. Lift it out, reseat the mesh and try again rather than pushing harder and cracking the plastic locking tabs.
Leaving grit in the recess Debris under the mesh edge keeps it from lying flat, and wash water then bypasses the filter straight into the pump. Clean the groove before installing.
Ordering by appearance Bosch sold several look-alike mesh filters. Match the part number against your model list or you may receive a filter that is a few millimeters off and never seats.
Running the machine without the mesh Even one cycle without the fine filter can push food scraps into the circulation pump and cause noises or a clogged drain later.
Troubleshooting After Installation
Dishes come out gritty after the swap Remove the filter set again and confirm the mesh is flat and the cylinder is locked. Clean the spray arm nozzles, which may hold debris that slipped past the damaged old filter.
Water pools in the sump at cycle end Pull the cylinder filter and check the drain opening for a plug of debris. Brush out the pump inlet, reseat both filters and run a rinse cycle.
Cylinder filter pops loose during the cycle The mesh is probably sitting slightly raised, so the cylinder cannot fully engage. Reseat both parts and twist the cylinder until the arrows line up.
Grinding or buzzing from the bottom of the tub Something hard passed the old filter and reached the pump. Remove the filter set and use a flashlight to look for glass or pits in the pump inlet.
Care Tips After the Repair
- Rinse the cylinder filter and mesh under warm water every one to two weeks, more often if you do not scrape plates.
- Scrub the mesh with a soft brush and dish soap; stiff wire brushes can tear the screen.
- Scrape large scraps off plates before loading so the filter does not clog between cleanings.

Frequently Asked Questions
Do I need to shut off power to replace the fine filter?
No wiring is involved, so you do not need to unplug the dishwasher. Just make sure the machine is not in the middle of a cycle and the tub has drained.
Can I clean the old filter instead of replacing it?
If the mesh is intact, cleaning is all it needs. Replace it when you see tears, holes, a warped frame or a lip that no longer sits flat in the recess.
Why does 00441905 fit so many models?
Bosch used the same sump filter layout across many series, which is why our data lists 645 compatible models including 63016304404 and SHI4306UC12. Still confirm your exact model number.
Does the fine filter include the cylinder filter?
No, 00441905 is the flat mesh only. If the cylinder microfilter is cracked or its lugs are broken, order it as a separate part.
