Solid Hardwood, Engineered and Laminate Flooring - Pergo under Dishwasher?

I would like to have my Pergo installed under my dishwasher.
The installer advised against this due to heat. What is your opinion? We are getting the glued type of Pergo.

As long as it is glued and siliconed around the perimeter of the dishwasher i don't see a problem with it.

I absolutely would not do it! Heat and moisture can be cause for a number of very undesirable problems. The floor will also elevate the appliance and that may cause another problem, Space.

Have done it several times oldest being two years ago even had a leak from the dishwasher and the floor was fine. Opinons will vary on this...

My concern is any leak at all and the floor retains serious damage but the real fear isn't successful installations, its the fact that moisture can be trapped under the planks and the result can be dangerous the health of the occupants. Moisture accumulation is a real potential and the rH can easily exceed 60% in many parts of the country and temperatures can easily exceed 80° under a dishwasher. This creates a breeding atmosphere for mold, black toxic mold. See EPA website. The combination of high humidity and temperature is the only cause of mold propagation. Moisture that would accumulate under planks will not dry as fast as on an open floor and in fact will persist long enough for mold incubation. I can't recommend spending money for an additional 9 or 10 square feet of material and labor to increase the risk of a family with no increased asthetic or functional value...

That is a very valid point but don't you think the same situation would exist under sheet, tile or other types of flooring. Or are you saying because of the underlayment acting as a sponge for these molds not to use it.

There is less space and most likely less risk that a glued down product would be invaded by water or moisture. That said, I'll bet you've seen some of the black stuff when removing vinyl or other sheet goods, that have been down for a long time, from a bath room or kitchen also. Not all black mold is toxic, in fact the MOST common one is NOT, but the toxic one of greatest concern is black.

Floating floors are very hard to seal 100% from invasion, some glueless brands have joints that require "play" by design so all in all it is best for me, not being knowledgeable of the specific application, brand or particular installer in question either pro or DIY, to express caution. The dish washer is only one possible source of high moisture but it is also one that also produces additional heat, and at the same time conceals the surface under the appliance from view. Mold incubation requires both moisture and heat and a little time. 'nuff said.
