Dishwasher Not Cleaning Dishes? Fixes for Utah Hard Water

Last checked: October 25, 2026

Note: Refrigerate LLC, the shop affiliated with this site, does not repair dishwashers. The shops listed below say they service dishwashers.

Likely causes

• Clogged filter
• Spray arm holes blocked by food or mineral scale
• Dishes loaded so they block the spray arms or detergent door
• Hard-water film and scale (common across much of Utah)
• Water not hot enough at the start of the cycle
• Low fill from a failing inlet valve, or a weak wash pump

Safe DIY checks

Safety first: unplug the appliance or switch off its breaker before touching anything inside, and shut off the water or gas supply where it applies. If you smell gas, leave the house and call your gas utility from outside.

1. Clean the filter.
2. Remove the spray arms and clear the holes with a toothpick, then rinse.
3. Make sure the spray arms spin freely and nothing tall blocks them.
4. Run the kitchen faucet until the water is hot before starting a cycle.
5. Use rinse aid and fresh detergent. Try a dishwasher cleaner for scale.
6. Check that the detergent door opens fully during the cycle.

When to call a pro

• Cleaning and loading changes do not help
• The dishwasher is not filling, or water is not getting hot
• You hear grinding or the wash motor is weak
• There is a leak or an error code

Typical repair cost in Utah

Call for a quote. Costs depend on the brand, the part and the shop, so ask for a written quote after diagnosis. Most Utah shops charge a diagnostic or trip fee, and many credit it toward the repair.

Repair or replace?

Cleaning fixes most cases. An inlet valve or wash pump can be worth replacing on a newer dishwasher. Read the repair or replace guide.
