Installing a dishwasher under an existing countertop

Hi Workshop Community!

I'm about to install a dishwasher in my house under an existing benchtop.

Are there any steps i need to do before installing the dishwasher? I've read online that I need to "seal" all the cabinetry, as the excess heat from the drying of dishes slowly degrades the exposed areas of the cabinetry.

Any help/recommendations would be really helpful!!

It would not hurt to seal the cabinetry. Prudent and preventive are the words that come to mind when it comes to installing a dishwasher. My only suggestion to you when installing the inlet hose is to include a small shut off tap at the point where you attach the hose to your cold water line. Many a flooded kitchen would have been prevented had that tap been installed. Going away for a few days? Turn the dishwasher tap off. Long vacation? Tap off. The washing machine hose has a fixed lifespan hence a safety tap will be a way to shut the water off without turning the water off on the whole house. Since we put smoke alarms in our houses it would only make sense to put a leak alarm at the most likely point of failure. A leak alarm is basicly a water activated alarm ( you can get one at Bunnings under the Family first brand ). That pretty much should cover it, should you run into any part that you need help with, don't hesitate to post a question here on the community.

Hi @redracer01,

Thanks so much for your post!

Is there any product that you would recommend to seal the cabinetry with?

Didn't think of the tap idea, but will definately take that on board 🙂

Thanks!

@mattylara027 Hi mate

Ive never heard of sealing the cabinets but if people say so then go for it but personally wouldn’t make a difference.

i wound just use a stop tap or a ball valve lever for your water connection, go to your toilet and have a look for the idea

good luck

Having looked at your photo it seems that most of the exposed surfaces are covered in laminate. It should be relatively safe to put your dishwasher in without adding more sealant. The tap is called a mini stop tap also known as a cistern tap. You can get the kinetic brand which is like 5 dollars a piece.

Hi @LePallet,

Thanks for the the input. It's more sealing the underside of the countertop from the residual steam that could be emitting from the Dishwasher when in Drying Mode. That was really the only reason for sealing the exposed surfaces 🙂

@redracer01, Thanks for all your help! Really appreciate it 🙂
