What's Involved
- Water supply connection: Mini stop cock or tee off the kitchen cold water
- Waste connection: Connect to kitchen sink waste via a dishwasher spigot or air gap
- Electrical: Needs a dedicated power point (electrician's job, not yours)
- Air gap requirement: AS/NZS 3500.2 requires the waste hose to have a high loop or air gap to prevent backflow
Compliance Note
Dishwasher installation that involves modifying the water supply or drainage is notifiable work in QLD. A simple like-for-like replacement on existing connections is generally not notifiable. If you're adding a new water supply tee or waste connection, lodge a Form 7.
