Hard Water and Your Dishwasher
If you live in the Inland Empire and have noticed white spots on your glasses, film on your dishes, or your dishwasher just isn't cleaning like it used to, hard water is almost certainly the culprit. The IE's water supply contains high levels of calcium and magnesium that wreak havoc on dishwashers over time.
Hard water affects your dishwasher in multiple ways: mineral deposits clog spray arm nozzles, reducing water pressure and coverage; calcium buildup coats the heating element, reducing its efficiency; and mineral residue accumulates on the interior walls, pump, and filter, gradually degrading performance.
Signs Your IE Dishwasher Needs Repair
- White film or spots on dishes: The classic sign of hard water damage — mineral deposits left behind after the water evaporates
- Standing water after cycle: A clogged drain pump or hose, often from mineral sediment buildup
- Dishes not getting clean: Blocked spray arms can't distribute water effectively
- Bad odor: Mineral buildup and food debris create a breeding ground for bacteria
- Error codes: E15 (water leak detected), E24 (drain blockage), and E09 (heating element failure) are common in IE dishwashers, especially Bosch models
- Door not latching: Heat-damaged seals and worn latches from the IE climate
