Kitchen Large Electric Appliances - air gap overflow

We experienced a serious over flow of water from the air gap of our one year old Whirlpool dishwasher.

I removed the chrome cover but cannot determine how to clean the air gap or to check for blockage or crimping. Instructions with the dw says unscrew plastic cap. I cannot locate a plastic cap that will unscrew.

Any advice regarding cause for overflow and/or maintenance to airgap?

Thanks for your help.

Hello: dicfor

Personally, I would simply suggest replacing that item. In my opinion, not worth the time and or work trying to or attempting to fix it. Jusy my personal opinion which may not agree with others.

So long as the dishwashers discharge lines are cleared and no restrictions or blockages exists in the lines of the dishwasher or garage disposal unit, replacing the air flow gap device usually resolves the problem.

Also suggest disregarding those instructions. Remove the cover cap. Should be a flange or nut on the top side with a nut under sink holding part in place. Yes. Gaskets too.

Replace that part and be done with it....:)

Thank you for your response and sound advice. I will replace the air gap. :)

One additional question, assuming the air gap is not malfunctioning, what else could cause the problem? :confused:

Thanks

Hi: dicfor

You asked "assuming the air gap is not malfunctioning, what else could cause the problem?"

All that has already been mentioned in the first reply. Which must be checked to help ensure the air gap is the cause b-4 purchasing and installing one.

Only to find out it was not the cause. Possibly is a restriction etc in a water discharge line, etc....???? Finding none would than suggest the air gap is the cause and replacing it will solve that problem....:)

Thanks, I apprediate your help.
