What Valley Water Does to Your Dishwasher

By Erik Jacobson, Jackpot Appliance Repair · Updated October 18, 2026

Las Vegas tap water is very hard, so minerals build up on dishwasher spray arms, filters and heaters. That causes white film, poor cleaning and eventually failed parts.

Signs of scale

White film on glasses, spots, gritty residue, or spray arm holes that look crusty.

What to do

Use rinse aid every load, run a dishwasher cleaner monthly, clean the filter every couple of weeks, and run the kitchen tap hot before starting a cycle.

When to call

If it still won't clean, won't drain or leaves standing water, a pump, inlet valve or heater may be failing. That's a repair.
