Problem: When dishwasher drains it dumps water to the sink through the air gap. Problem started accuring 6 month after kitchen/sink/dishwasher was installed and used.
What I tried:
- Opened the cover of the air gap and checked it was clean
- disconnected the 7/8 ID hose coming from the sink to the garbage disposal made sure it was clean.
- made sure garbage disposal is clean
Next thing I ran a new dishwasher cycle and the issue is not fixed. I took the cover off the air gap and observed it while water was dumping. The part of the air gap connected to the the dishwasher is shooting water in the air 5-6 inches.
Question: is that how dishwasher should be dumping water? There's no way this air gap design can work this way. Is my air gap assembly incomplete? When I take the cap off I see one 3/8in pipe inside the other (wider one). There's no cover of any sort to restrain water flow, so when dishwasher dumps the water it just spills out.
