Dishwasher Repair

The San Francisco Bay Area's moderately hard water is the #1 hidden enemy of dishwashers in our service territory. Calcium and mineral deposits gradually clog spray arm jets, coat heating elements with scale, and restrict water flow through inlet valves. In cities like Milpitas and Fremont — where water hardness often exceeds 150 ppm — we see spray arm replacements and inlet valve failures at nearly double the national rate. Our technicians always check water hardness during dishwasher repairs and recommend rinse aid adjustments or water softener solutions when appropriate. Bosch dishwashers are overwhelmingly popular in Bay Area kitchens, particularly the 800 series with CrystalDry. We've become specialists in Bosch-specific issues: E24 drain errors (usually a kinked drain hose or high-loop installation problem), E15 leak sensor activations (often caused by a cracked sump seal rather than an actual flood), and circulation pump noise that develops after 3-4 years of heavy use. If your Bosch flashes an error code, chances are we've seen it dozens of times. Troubleshooting checklist before you call: ✓ Dishes still dirty after a cycle → check spray arms for mineral clogs, ensure water temp reaches 120°F. ✓ Standing water in the bottom → inspect the drain hose for kinks, clean the filter basket. ✓ White film on glasses → hard water deposits; try increasing rinse aid setting first. ✓ Dishwasher won't start → check the door latch click, test the outlet with another device. ✓ Leaking from the bottom → likely a worn door gasket or cracked sump — call us immediately to prevent subfloor damage.
