Dishwasher Repair That Gets Dishes Clean Again in Falls Church, VA
A dishwasher that leaves standing water, cloudy dishes, or a puddle on the kitchen floor is telling you something specific failed, not that it's time to replace the whole unit. We repair built-in dishwashers across Falls Church, from drain pumps and spray arms to door latches and leaks.

A dishwasher actively leaking onto a wood or laminate floor can cause water damage quickly — shut off the water supply and see our emergency appliance repair page for same-day priority dispatch. Kitchens with an under-sink garbage disposal sharing the same drain line sometimes have a disposal clog masquerading as a dishwasher drainage problem, which our garbage disposal repair page covers.
Why Dishwashers Stop Draining or Cleaning Properly
A dishwasher relies on a drain pump to push wastewater out through a hose that typically ties into the kitchen sink's drain line or garbage disposal, often looping up under the counter to prevent backflow. When food particles, glass shards, or labels from jars work past the filter and into the pump, they jam the impeller or lodge in the check valve, leaving water trapped at the bottom of the tub after every cycle. The same debris path affects the spray arms, whose small jets are sized precisely to build water pressure; even partial clogging drops that pressure enough that dishes on one rack come out visibly dirtier than the other.
Leaks at the door almost always trace back to the gasket, a rubber seal that runs around the door frame and compresses each time the door latches. Years of heat cycling make this rubber stiffen and crack, and it eventually stops sealing evenly against the tub. A float switch that sticks in the down position can also let the machine keep filling with water well past the point it should stop, overflowing at the weakest point in the seal, which is usually the door.
When You Don't Need a Repair Visit
- Cloudy glasses and plates are often hard water mineral etching rather than a mechanical failure — try a rinse aid refill and a citric acid cleaning cycle before assuming a part broke.
- A small amount of water sitting around the drain area at the very bottom of the tub is normal on many models and not necessarily a sign of a clogged pump.
- If dishes aren't getting clean, check that they aren't blocking the spray arm's rotation before assuming the arm itself failed.
How We Diagnose and Repair Dishwashers
-
Describe the Symptom
Call (571) 761-5477 with the issue — drainage, cleaning, leaking, or won't start — and the brand if you have it.
-
On-Site Diagnosis
The technician checks the drain pump, hose, and check valve, inspects the door gasket and latch switch, and tests spray arm rotation and pressure.
-
Repair
Pumps, gaskets, spray arms, and latch switches are typically stocked and replaced the same visit.
-
Full Cycle Test
We run a complete wash cycle to confirm proper draining, cleaning, and sealing, and check underneath and around the door for any residual leak.
What to Check Yourself First
- Clean the filter basket at the bottom of the tub, which traps food debris and needs regular rinsing.
- Check that the garbage disposal knockout plug was removed if the dishwasher was recently installed alongside a new disposal.
- Make sure the rinse aid dispenser isn't empty, which affects both drying and spotting.
- Confirm the door latches fully and clicks shut before pressing start.
- Run the kitchen sink's hot water briefly before starting a cycle so the dishwasher fills with hot water from the first fill.
Dishwasher Repair FAQs
Why does standing water collect at the bottom of my dishwasher?
A small amount of water sitting around the drain after a cycle can be normal on some models, but a deep pool usually means the drain pump, check valve, or drain hose is blocked or has failed. Food debris and glass fragments are common culprits lodged in the pump impeller.
Why do my dishes come out with a cloudy, filmy residue?
Cloudy residue is frequently hard water mineral buildup rather than a mechanical fault, especially in Northern Virginia's harder municipal water. A rinse aid dispenser that has run dry or a worn dispenser seal can also leave spots that look like a washing failure.
Why does my dishwasher leak from underneath the door?
A leak at the door is typically caused by a worn or torn door gasket that no longer seals evenly, overfilling from a stuck float switch, or too much regular dish soap creating oversudsing that pushes past the seal during the wash cycle.
Why won't my dishwasher start when I press the button?
A dishwasher that won't start can be as simple as the door latch not engaging fully, which most models require before the control board will run a cycle, or it can point to a tripped breaker, a blown thermal fuse, or a failed control board.
Why does one spray arm seem to do nothing during the cycle?
Spray arms have small jets that clog with mineral deposits and food particles over time, and a cracked or disconnected arm can also spin freely without actually distributing water. Removing and soaking the arm often restores flow, but a cracked arm needs replacement.
Is it normal for a dishwasher to smell bad even when it's running fine?
A persistent odor usually comes from trapped food debris in the filter basket at the bottom of the tub, or from a partially clogged drain line that lets standing water go stagnant between uses. Both are worth checking before assuming a part has failed.
