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
Scale on a component that was never meant to carry it
On the groundwater end of this valley, deposit on a pump impeller or fan hub unbalances it, and the noise arrives long before the part actually fails.
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
This is the local fact that matters most for anything plumbed. Groundwater at 11 to 26 grains per gallon is harder than Las Vegas; the imported blend at 4.5 to 9 is not. Two houses a few streets apart get genuinely different water, so a descaling interval that works at one address is wrong at the other, and a softener sized for a previous house is usually wrong at this one.
