Most appliance repair companies in LA don't mention water hardness when they diagnose a Los Feliz dishwasher or ice maker. We do, because the LADWP water in 90027 is part of the actual cause for a significant share of the calls we run here.
Hard water tip from our techs: If you're in Los Feliz and your dishwasher is leaving spots on glasses that were never there before, or your ice maker is producing less ice than it used to — mineral buildup is the likely culprit. Running a dishwasher cleaning tablet monthly and using a refrigerator water filter (replace every 6 months, not 12) both help significantly in this ZIP code.
The most common pattern: a Bosch dishwasher in a Franklin Hills kitchen with spray arm ports almost completely blocked by mineral scale, glasses coming out cloudy, the customer assuming the pump or motor has failed. The actual fix is descaling the spray arms and the filter trap, running a cleaning cycle with citric acid, and setting up monthly maintenance. We see this same call multiple times a month in Los Feliz.
On vintage ranges — the original O'Keefe & Merritt, the Wedgewood, the early Magic Chef — most failures are corroded igniter contacts, worn pilot assemblies, weakened thermocouples. None of that is exotic. We clean, adjust, and replace using parts that are still available. A vintage range that's been in a Spanish Revival kitchen for 70 years is almost always worth keeping.
