How to Install Dishwasher Fine Filter 00357393 in a Thermador Dishwasher
Quick answer: Slide out the lower rack, lift off the lower spray arm, twist the cylinder filter counterclockwise and lift it out, remove the old flat filter, clean the sump, lay 00357393 flat in the tub floor, drop the cylinder in and turn it clockwise until the arrows align, then run a rinse cycle.
The fine filter 00357393 is the flat mesh screen that covers the sump opening in the floor of a Bosch-built Thermador dishwasher. It works together with the cylindrical micro filter that sits in its center: wash water drains through the mesh, food particles are trapped before they reach the pump, and the filtered water is recirculated through the spray arms. When the mesh tears, warps or clogs with grease that will not wash off, you get gritty glasses, food bits redeposited on plates, slow draining and sometimes a drain error on the display. Replacing it takes minutes and needs no tools.
This part is listed for Thermador models such as DWHD630GCP53, DWHD630GCM53 and DWHD630GPR53, and for Bosch dishwashers built on the same tub, including SHX68P05UC53, SHV68P03UC60 and SHE65P05UC53. The layout is the same across the family: a lower spray arm on a hub, a twist-lock cylinder filter under the hub, and the flat fine filter beneath both. The steps below cover removal, cleaning the sump while it is exposed, and seating the new filter so it lies flat and the cylinder locks properly, which is the detail most people get wrong.

- Let the dishwasher cool if it has just finished a cycle; the tub floor and the water in the sump can be hot.
- Cancel any cycle and wait until the pump stops before you reach into the sump.
- Broken glass often collects in the sump. Look with a flashlight before putting your fingers in.
- Do not pry the cylinder filter loose with a knife or metal tool; the plastic tabs snap easily.
Tools and Parts You Need
- Soft-bristle brush or old toothbrush
- Dish soap and warm water
- Microfiber towel
- Flashlight to inspect the sump
- Wooden toothpick to clear spray arm nozzles
- Rubber gloves, optional, since the sump can hold greasy water
Step-by-Step Installation
- Empty the bottom of the tub Open the door fully, slide out the lower rack and set it aside, along with any silverware basket, so you have a clear view of the tub floor.
- Lift off the lower spray arm Grip the spray arm near its center hub and pull straight up. On these tubs it lifts off its mount without unscrewing. Check the nozzles for stuck seeds or glass.
- Unlock the cylinder filter Twist the cylindrical filter in the middle of the tub floor counterclockwise about a quarter turn until the arrows line up with the unlock mark, then lift it straight out.
- Remove the old fine filter The flat filter now lifts free. Tilt one edge up to break the water seal and lift it clear, noting which way its shaped opening faced.
- Clean the sump Shine a flashlight into the sump and remove anything trapped there: glass shards, labels, fruit stickers or toothpicks. Wipe the flat ledge where the fine filter sits, since grit under the filter stops it from lying flat.
- Seat the new fine filter Lay 00357393 flat in the recess with its opening centered over the sump. Press gently around the edge until it sits fully down and does not rock. It must sit under the spray arm hub, not over it.
- Lock the cylinder filter Drop the cylinder down through the opening in the fine filter and rotate it clockwise until the arrows on the filter and tub floor align and it stops. A loose cylinder lets debris into the pump.
- Refit the spray arm and rinse Press the spray arm back onto its hub until it clicks and spins freely. Slide in the lower rack and run a short rinse cycle with no dishes to confirm normal spraying and complete draining.
Fit Checks Before You Call the Job Done
- Confirm the model number on the edge of the door appears in the list for 00357393, for example DWHD630GCP53 or SHX68P05UC53.
- Compare the outline of the new filter with the old one; the cutout for the cylinder and the outer edge should match exactly.
- With the filter seated, it should be flush with the tub floor and not rock when pressed at the corners.
- After locking the cylinder, try lifting it without twisting; it should stay put.
- The lower spray arm must spin freely by hand after reassembly; if it drags, the filter is not fully seated.
Common Mistakes to Avoid
Laying the fine filter on top of the hub The flat filter goes under the spray arm hub, not over it. Installed on top it never seals and the arm will not click on.
Turning the cylinder the wrong way Clockwise locks, counterclockwise unlocks. Twisting the wrong way while pushing down can crack the tabs. Watch the arrows.
Skipping the sump cleanout A new filter over a dirty sump clogs in days. Spend two extra minutes with a flashlight and a towel.
Running the dishwasher with the filter out One cycle without the fine filter can send debris into the pump and drain hose, a far bigger repair than a filter.
Troubleshooting After Installation
Dishwasher will not drain after the swap The cylinder filter is probably not locked, so a tilted filter partly blocks the pump inlet. Reseat both filters and check the drain hose for a kink.
Grit still on clean dishes Check that the fine filter is flat and the cylinder fully locked, then clear the spray arm nozzles and run an empty cleaning cycle.
Spray arm will not click back on The fine filter is sitting on the hub instead of under it. Pull the arm, lift the filter, and reseat it below the hub.
Care Tips After the Repair
- Rinse the fine and cylinder filters under warm water weekly if you wash heavily soiled pots, or every two weeks for light use.
- Run a monthly empty cycle with dishwasher cleaner or a cup of white vinegar to dissolve grease film on the mesh.
- Inspect the mesh for tears whenever you clean it and replace it at the first hole rather than waiting for a clog.

Frequently Asked Questions
Do I need any tools to replace 00357393?
No. The spray arm lifts off, the cylinder filter twists out by hand, and the fine filter lifts free. A brush and a flashlight are all you need.
Which Thermador dishwashers use this filter?
It is listed for DWHD630GCP53, DWHD630GCM53 and DWHD630GPR53 among others, plus Bosch models such as SHX68P05UC53, SHX68R52UC63 and SHE65P05UC53 that share the same tub. Check your model number on the door edge.
Should I replace the cylinder micro filter at the same time?
Only if it is cracked or its mesh is torn. Related parts listed with this filter, such as 00481957 and 00361113, may cover other filter components; verify fit before ordering.
How often does the fine filter need replacing?
With regular cleaning it lasts for years. Replace it when the mesh tears, the frame warps so it no longer lies flat, or grease film will not come off.
