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 redeposits 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.
