LG 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 slab floor transmitting compressor vibration
With no crawlspace and no joists to absorb it, vibration travels through the slab and resonates in the cabinet run rather than damping out.
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
In an Eichler a new water line cannot go under the floor, because there is no floor to go under — the slab carries the radiant heating loop, and cutting it turns a kitchen job into a heating job. Lines here run overhead or around the perimeter, which is why the same repair takes longer on one street than on the next.
