What does it cost to hire out "Clean the dishwasher filter"?

A fair national range is $100–$180; local labor costs move that number up or down by county.

How often should this be done?

Quarterly, typically January, April, July, and October. Local frost dates can shift the timing.

What should I ask before hiring someone for this?

Worth asking: Was it the filter, the drain pump, or the drain line — and can you show me the part that was actually clogged? While you're in there, is the spray arm spinning free and are its holes clear? Is the air gap or high loop on the drain hose set up right, or is sink water backing in?

How do I know I'm being upsold on this job?

Watch for: A drain-pump replacement quote when nobody's shown you a filter — a matted filter causes most 'won't drain' and 'doesn't clean' calls, and it's a twist-out part. A 'dishwasher tune-up plan' subscription. The tune-up is this card, four times a year, free. Replacement pitch for a machine under 8 years old over a drainage complaint. Dishwashers die of pumps and boards, not dirty filters.

Clean the dishwasher filter

Quarterly · typically January, April, July, and October

Why it matters

Older dishwashers had hard food grinders. Nearly every machine built since about 2010 traded the grinder for a quiet manual filter — a cylinder-and-screen assembly in the floor of the tub that catches everything that comes off your plates. The manual never got read, so the filter never gets cleaned, and a year of grease and food film later the symptoms show up: cloudy glasses, grit on "clean" dishes, a swampy smell when you open the door, water pooling in the bottom.

None of that is a broken dishwasher. It's a full filter.

What skipping it costs

$150–$700

Most dishwashers since about 2010 have a manual filter that nobody told the owner about. It mats over with grease and food film, the machine 'stops cleaning,' and a $150 service call — or a $700 'it's not worth fixing' replacement — stands in for a ten-minute rinse at the sink.

Two ways to get it done

Do it yourself

~10 min · difficulty 1 of 5

You'll need: Old toothbrush or soft brush, Dish soap, Warm water.

Pull the bottom rack. Look at the floor of the tub — you're looking for a round, twist-out cylinder (often with a flat mesh plate around it).
Twist it counterclockwise and lift it out. Brace yourself the first time; a never-cleaned filter is a memorable object.
Rinse under hot water and scrub with the toothbrush and a drop of dish soap until the mesh is see-through again. No dishwasher-safe shortcut here — the sink is the way.
While it's out, spin the lower spray arm and check its holes for stuck seeds and paper bits — clear them with a toothpick.
Seat the filter and twist it clockwise until it locks. A loose filter lets debris into the pump, which is how a $0 chore becomes a real repair.
Smell still there after a clean filter? Run the hottest cycle empty with a bowl of white vinegar upright on the top rack. That's the whole "machine cleaner" aisle in one move.

Hire it out

$100–$180National fair range — local labor moves this number.

There's no version of this worth a standalone service call — but if a tech is already out for a real drainage problem, the visit runs $100–$180 and the filter should be the FIRST thing they pull, in front of you, before any talk of pumps. A pro who skips the filter and opens with a parts quote has told you what kind of visit this is.

Rinse-aid, since it comes up on every service call: it's not a scam — it genuinely fixes water spots and helps drying — but it's a $4 bottle, not the $15 branded one, and it has nothing to do with drainage or smell. Filter first, always.

Ask the tech

Was it the filter, the drain pump, or the drain line — and can you show me the part that was actually clogged?
While you're in there, is the spray arm spinning free and are its holes clear?
Is the air gap or high loop on the drain hose set up right, or is sink water backing in?
