Gaggenau Refrigerator Ice Buildup
Refrigerator Ice Buildup 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
Aggressive water at the valve seat
Nothing furs up at 1.3 to 2.4 grains per gallon; what happens instead is pitting and a valve that no longer seals.
A blocked or frozen water supply line
Shows up as slow or stopped production, and is a plumbing-side issue rather than the ice-making mechanism itself.
A worn ice maker motor or mold assembly
The mechanical components that form and eject cubes wear out gradually.
Local conditions that matter here
This is a marine climate with a long cool wet season, so a cold door seal here rarely gets a chance to dry between cycles. A gasket that lives damp perishes and loses its set rather than tearing, which passes a visual check and still leaks — which is why so many of these arrive reported as a unit that runs constantly for no visible reason.
