Dishwasher
The self-cleaning food grinder disappeared from most dishwashers years ago â modern units rely on you pulling out a filter basket and rinsing it by hand, and skipping that is the real reason "clean" dishes start coming out gritty or smelling off.

Answer a few quick questions and get a personalized diagnosis from the HomeShape Repair Coach.
Select your type
The vast majority of residential dishwashers â installed under the counter next to the sink, sharing water supply and drain connections with it. Nearly all current models use a manual filter instead of the old built-in food grinder, which is exactly why filter cleaning became a real homeowner task instead of a set-and-forget appliance.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Remove and rinse the filter Twist and lift out per the manual, rinse under warm water | Every 3â6 months, more with heavy use or no pre-rinsing | 1 ¡ Beginner | 10â15 min | A clogged filter recirculates food particles onto "clean" dishes and can cause draining issues or odors |
Wipe down the door gasket Clean along the rubber seal where food debris collects | Monthly | 1 ¡ Beginner | 5 min | Food debris and mold can build up along the seal, causing odors and, eventually, a leak |
Check spray arm holes for clogs Clear any blocked holes with a toothpick or small brush | Every 3â6 months | 1 ¡ Beginner | 10 min | Clogged spray arm holes create uneven water pressure and leave dishes poorly cleaned in specific spots |
Run an empty cleaning cycle Use a dishwasher cleaner or a bowl of vinegar on the top rack | Monthly | 1 ¡ Beginner | 5 min active, plus a full cycle | Mineral buildup and grease film inside the tub and hoses reduces cleaning performance and can cause odors |
Check the drain air gap or high-loop Confirm the drain path isn't restricted | Annually, or if draining seems slow | 2 ¡ Confident | 15â20 min | A clogged air gap or improperly routed drain hose can let dirty water siphon back into the dishwasher |
Use rinse aid consistently Keep the reservoir filled | Ongoing, refill as needed | 1 ¡ Beginner | 2 min | Without rinse aid, water sheets and dries as spots, and over years can etch glassware permanently |
Check the water inlet screen if fill time seems slow Inspect and clear the small screen where the water line connects | As needed | 2 ¡ Confident | 15â20 min | A clogged inlet screen restricts water flow, extending cycle times or causing fill errors |
Troubleshooting
Symptom
Likely cause
Action
Who
Dishes come out with food debris or grit
A dirty filter recirculating particles
Remove and thoroughly rinse the filter
DIY ok
Standing water in the tub after a cycle
A clogged filter, drain hose, or air gap
Clean the filter first, then check the air gap and drain hose for clogs
DIY ok
Persistent musty or foul odor
Food debris trapped in the filter, gasket, or spray arms
Clean all three; a monthly cleaner cycle helps prevent recurrence
DIY ok
Glassware looks cloudy or etched
Hard water mineral deposits, or permanent etching from years without rinse aid
Try a vinegar rinse for cloudiness; true etching from years of neglect can't be reversed
DIY ok
Dishwasher won't drain at all
A clogged drain hose or air gap, or a disposal knockout plug never removed on a new installation
Check for a garbage disposal knockout plug if this is a new install; otherwise clear the drain path

Recommended tools & materials
Single or double dish drawers that pull out like a regular kitchen drawer instead of opening downward. Each drawer typically runs as its own independent unit, which means a double-drawer model effectively has two separate systems to maintain rather than one.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Remove and rinse each drawer's filter Service each drawer separately | Every 3â6 months, per drawer | 1 ¡ Beginner | 10â15 min per drawer | Each drawer clogs independently, so cleaning only one on a double-drawer unit leaves the other silently degrading |
Wipe down each drawer's door gasket Clean the seal on both drawers, not just one | Monthly | 1 ¡ Beginner | 5 min per drawer | Same seal-degradation and odor risk as any dishwasher, doubled across two drawers |
Check that both drawers close and latch fully Confirm a solid seal on each | Every 6 months | 1 ¡ Beginner | 5 min | A drawer that doesn't seal completely leaks water onto the surrounding cabinetry |
Run a cleaning cycle in each drawer Treat each drawer as its own appliance | Monthly, per drawer | 1 ¡ Beginner | 5 min active, plus a full cycle | Mineral and grease buildup affects each drawer's own tub and spray mechanism independently |
Check shared drain/water connections Inspect the connections both drawers rely on | Annually | 2 ¡ Confident | 15â20 min | A shared supply or drain line issue can affect both drawers even though the wash chambers themselves are independent |
Troubleshooting
Symptom
Likely cause
Action
Who
One drawer cleans well and the other doesn't
The drawers are independent systems, so a clog or filter issue in one doesn't affect the other
Clean that specific drawer's filter and spray arm
DIY ok
A drawer doesn't fully latch or seals poorly
A worn latch mechanism or gasket
Inspect and replace the latch or gasket for that drawer
DIY ok
Water pools between the drawer and the cabinet
A failed seal on that specific drawer
Address that drawer's gasket promptly to avoid cabinet water damage

Recommended tools & materials
Connects temporarily to the kitchen faucet instead of being plumbed in permanently â common in rentals, small kitchens, or as a supplement to a full-size unit. The hookup itself, not just the wash mechanism, is the part that needs the most regular attention.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Inspect the faucet adapter and hose Check the connection before each use | Before connecting, each use | 1 ¡ Beginner | 2 min | A worn or improperly seated adapter is the most common cause of a leak at the sink connection |
Remove and rinse the filter Same filter-cleaning routine as any dishwasher | Every 3â6 months | 1 ¡ Beginner | 10â15 min | Same clogging and re-soiling risk as any dishwasher |
Store the fill/drain hoses properly Coil without kinking between uses | After each use, if not left connected | 1 ¡ Beginner | 5 min | Kinked or crimped hoses stored carelessly can crack or fail at the next connection |
Wipe down the door gasket Same seal-cleaning routine as a built-in unit | Monthly | 1 ¡ Beginner | 5 min | Same seal and odor risk as a built-in unit |
Check caster wheels and leveling Confirm the unit sits stable and level | Every few months | 1 ¡ Beginner | 5 min | A wobbly or unlevel unit can affect drainage and wash performance |
Run a cleaning cycle Same deep-clean routine as any dishwasher | Monthly | 1 ¡ Beginner | 5 min active, plus a full cycle | Same mineral and grease buildup risk as any dishwasher |

Water leaks at the faucet connection during a cycle
A worn or improperly seated faucet adapter
Replace the adapter or its washer, and confirm it's fully seated before each use

Unit won't connect to a newer faucet
An aerator or faucet style incompatible with the adapter
Check for a compatible adapter kit for that faucet style

Poor wash performance despite a clean filter
Insufficient water pressure or flow from the temporary connection
Confirm the faucet is fully open and the hose isn't kinked
