What these models have in common
This is the profile page for the Bertazzoni ZS refrigerator family — what it covers and what goes wrong on it. The models are in the table; the faults worth knowing about are cooling loss, drainage, ice production and noise, in that order of how often they come up.
Problems that happen on these models
- Running but not cooling — The cabinet drifts warm while the compressor is clearly audible. — Slug: bertazzoni-bertazzoni-refrigerator-zs-refrigerator-cooling-failure — Title: Bertazzoni ZS Refrigerator: Not Cooling or Not Freezing
- Water inside the cabinet or on the floor — Where the water starts decides the cause — under the crispers means the defrost drain, behind the unit means the pan or the supply line. — Slug: bertazzoni-bertazzoni-refrigerator-zs-refrigerator-water-leak — Title: Bertazzoni ZS Refrigerator: Water Leak
- Buzzing, grinding or rattling — Timing separates these faults far better than the sound does, and the noise page works through the door test, the cycle test and the machine compartment in that order. — Slug: bertazzoni-bertazzoni-refrigerator-zs-refrigerator-abnormal-noise — Title: Bertazzoni ZS Refrigerator: Abnormal Noise or Vibration
- No ice, or hollow and undersized cubes — The shape of what the maker produces names the fault: nothing at all points at the supply, hollow cubes at an interrupted fill. — Slug: bertazzoni-bertazzoni-refrigerator-zs-refrigerator-ice-production — Title: Bertazzoni ZS Refrigerator: Ice Maker Fault
