Not draining, pump failure, not cleaning — Same-day, fixed quote.
Charlotte's Catawba River water at 32–68 PPM means spray arm calcium blockage is essentially absent as a dishwasher failure mode — one of the clearest soft-water appliance advantages in the Southeast. When Charlotte dishwashers underperform, the cause is almost always mechanical: pump failure, drain filter blockage, worn spray arm bearing, or control board fault. Charlotte's finance industry households in SouthPark and Myers Park also generate a disproportionate volume of Miele and Bosch dishwasher service calls requiring brand-specific diagnostic knowledge.
Miele dishwashers have a built-in softener requiring periodic salt replenishment. Charlotte homeowners frequently skip this because Charlotte water is already soft — but depleted Miele salt produces white film and poor cleaning identical to a pump or spray arm fault. We check salt level before any other Miele diagnostic step, every time, in Charlotte.
