Waikiki Hotel: Dishwasher Water Spots Cut in 60 Days

Home 9 Case Studies and Results 9 Waikiki Hotel: Dishwasher Water Spots Cut in 60 Days
Key results
Noticeable scale drop in 60 days
Far fewer water spots
Better dishwasher performance

Case Study from HydroFLOW USA

The Challenge

  • Dishwasher water spotting was affecting dishes and particularly glassware
  • Scale accumulated across internal dishwasher surfaces
  • Build-up could reduce heat-transfer efficiency
  • The hotel wanted a measurable reduction rather than a one-off clean
  • Inspections needed to run long enough to show a trend

The Solution

One HydroFLOW® S38 was fitted to the three-quarter inch galvanised pump line between the filter heater and the dishwasher, with follow-up inspections across approximately six months. A noticeable limescale reduction was recorded within 60 days, later inspections showed less visible scale on the monitored surfaces, and water spotting on dishes and glassware fell significantly.

Key Outcomes
