Quick Answer: Why Isn't Your Dishwasher Cleaning Properly?
If your dishwasher leaves dishes dirty, won't drain, or has standing water, common causes include a clogged spray arm, failed drain pump, broken wash motor, or malfunctioning control board. Most dishwasher repairs in Woodbridge VA take 1-2 hours and cost $100-$300.
| Problem | Likely Cause | Typical Cost |
|---|---|---|
| Not cleaning dishes | Clogged spray arm, wash motor, or water inlet | $100-$250 |
| Won't drain | Drain pump, check valve, or clogged hose | $120-$280 |
| Leaking | Door gasket, pump seal, or spray arm | $100-$250 |
| Won't start | Door latch, control board, or thermal fuse | $80-$300 |
| Not drying dishes | Heating element, vent, or rinse aid dispenser | $80-$200 |

Hard water is the silent killer of dishwashers in Northern Virginia. Manassas, Gainesville, and parts of Bristow have some of the hardest municipal water in the D.C. metro area, measuring 10-15 grains per gallon. That mineral content clogs spray arms, coats heating elements, and gums up the wash motor impeller. We see dishwashers in those areas fail 2-3 years earlier than identical models in Fairfax or Alexandria where the water is softer. When we repair a dishwasher in a hard-water area, we always descale the interior components and recommend a monthly citric acid rinse cycle to extend the life of the machine.
Common Dishwasher Repair Problems We Fix
Dishwasher Not Cleaning
Dishes coming out with food residue, spots, or film usually points to clogged spray arms, a worn wash pump, insufficient water temperature, or a failing detergent dispenser. We inspect the entire wash system and restore cleaning performance.
Dishwasher Won't Drain
Standing water at the bottom of the tub after a cycle means the drain pump, check valve, or drain hose is blocked or failing. We also check whether the garbage disposal knockout plug was removed during installation - a surprisingly common oversight.
Dishwasher Leaking
Water on the floor near your dishwasher can come from the door gasket, a cracked tub, loose hose clamps, a worn pump seal, or the door latch not sealing properly. We trace the leak source and fix it to prevent kitchen floor damage.
Dishwasher Won't Start
A dishwasher that does nothing when you press start may have a blown thermal fuse, a faulty door latch switch, a tripped float switch, or a control board failure. We systematically test each component to find the root cause.
Dishes Not Drying
If dishes are clean but soaking wet after the drying cycle, the heating element, vent assembly, or rinse aid dispenser may be the issue. On models with condensation drying, a final hot rinse temperature problem can also prevent proper drying.

Frequently Asked Questions
Bosch dishwashers commonly fail to drain due to a clogged fine mesh filter at the bottom of the tub, a stuck check valve in the drain pump, or a blocked drain hose. The first thing to check is the filter - it should be cleaned monthly.
Most dishwasher repairs run $100 to $300. Simple fixes like spray arm or gasket replacement are under $150. Drain pump and control board repairs are higher. We always quote before starting work.
If the dishwasher is under 7-8 years old and the repair is under $250, repair is usually the better value. Dishwashers have a shorter lifespan than other appliances (8-12 years), so age is a bigger factor in the repair vs. replace decision.
