Dishwasher Not Cleaning Well — Repair Cost
Grit on glasses, food still on plates, detergent pod half-dissolved in the door. Before blaming the machine: most cleaning complaints trace to a dirty filter, blocked spray arms, cold water, or loading — all free to fix.
National averages for independent repair companies. Service-call/diagnostic fees ($75–$150) are usually applied toward the repair. Costs vary by brand, model, and city.
What causes it — and what each fix costs
Filter overdue for cleaning
Modern dishwashers have no grinder — the filter catches everything and needs a monthly rinse. A packed filter re-deposits dirty water on your dishes.
Spray arm jets blocked
Hard-water scale and seeds plug the little holes. Pop the arms off and clear them with a toothpick.
Water not hot enough
Run the kitchen tap hot before starting; the first fill should arrive at 120°F. A failing heating element also lands here.
Circulation pump weak
A quiet wash with poor results after everything above checks out — the wash motor is tired.
Detergent/hard water chemistry
Arizona water is brutally hard — use quality pods, fill the rinse-aid, and run a citric-acid cleaner monthly.
Repair or replace?
Almost always maintenance, not repair. A genuinely weak circulation pump on an older budget machine is the one replace-worthy outcome.
We'll quote you on hauling it away — or buying it.
Not every dishwasher is worth repairing, and we'd rather tell you that than sell you a repair. If you're replacing it, we'll give you a free quote either way: scrap pickup for a machine that's finished, or a cash offer if it still has life in it. Working units, recent models and premium brands are often worth real money.
Common questions
Why is there sand-like grit on my glasses?
That’s redeposited food ash from a packed filter — the signature symptom. Clean the filter and run a hot empty cycle with dishwasher cleaner.
