How to Clean Your Dishwasher Filter (5-Minute Guide)
The filter is the most neglected part of your dishwasher — and the cause of most "not cleaning" and "not draining" complaints. Cleaning it takes 5 minutes and requires zero tools. Here's how, for every major brand. Want A One Dishwasher Repair WA to handle the full tune-up instead? (253) 549-3002 — annual maintenance across Washington.

2. Find the filter. It's the cylindrical assembly in the center (or rear corner on some GE/Hotpoint models) of the tub floor. On Bosch: twist the center cylinder counterclockwise. On Whirlpool/Maytag/KitchenAid: lift the lower spray arm slightly, then twist the filter counterclockwise. On Samsung/LG: twist the round filter cap.
3. Lift it out. Most assemblies come out in 1–3 pieces: coarse filter, fine filter, sometimes a microfilter. Note the order for reassembly (phone photo helps).
4. Scrub it. Hot water + dish soap + an old toothbrush or soft brush. Get into the mesh. If there's greasy buildup that won't budge, soak 10 minutes in hot water with 1 cup of white vinegar.
5. Clean the sump area. With the filter out, wipe the sump basin underneath with a damp cloth — remove any glass shards (carefully!) or food chunks sitting there.
6. Reinstall in reverse order. Make sure it locks/twists fully into place. A loose filter lets debris straight into the pump — the exact thing you're preventing.
7. Run a test. Empty quick cycle. Done.
How Often?
Monthly. Every month, no exceptions — more often if you don't scrape plates well or have a big household. Set a phone reminder. This single habit prevents more service calls than anything else you can do.
While You're Down There
- Check the spray arms — spin them; clear clogged holes with a toothpick
- Wipe the door gasket — the folds collect black gunk
- Look at the heating element — heavy white scale means it's time for a descale cycle
When Filter Cleaning Isn't Enough
If dishes are still dirty or water still stands after a clean filter, the problem is downstream: clogged spray arms, a weak wash pump, or a failing drain pump. That's a tech job — same-day across Washington: (253) 549-3002. Or book our annual tune-up and never think about the filter again.

Dishwasher Filter FAQs
Where is the dishwasher filter located?
Tub floor, center or rear — a twist-out cylindrical assembly under the bottom rack. All major brands put it there.
Can I put the filter in the dishwasher to clean it?
Funny, but no — hand-wash it. The dishwasher can't clean its own filter effectively.
My filter is damaged/torn — can it be replaced?
Yes, filters are inexpensive parts. Running with a torn filter destroys pumps, so replace it promptly — we stock them.
A dirty filter is behind most dishes not getting clean and dishwasher not draining complaints — start here before anything else.
