Bosch Dishwasher Making Loud Noise
Dishwasher Making Loud Noise is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A unit shimmed into an out-of-square Victorian opening
Pre-war framing has moved for a century, and a cabinet that is no longer square lets the compressor mounts resonate against the casework instead of isolating.
A failing fan motor
Evaporator or condenser fan bearings wear out gradually, producing noise well before the fan actually stops running.
Loose or vibrating panels
Cabinet panels or compressor mounts that have loosened over time can resonate against nearby surfaces.
Local conditions that matter here
Hetch Hetchy water arrives at 1 to 3 grains per gallon, among the softest supplies in the country, so scale is rarely the answer in this city. Soft, low-alkalinity water lays down no protective film and slowly strips the one that is there, which is why failures here show up as pitting and weeping joints on copper fill lines rather than as a furred-up valve.
