Which De Dietrich model did you have, and where did you buy it from?

I have a 308X which I bought from Cookpower in New Zealand and it's been working fine so far -- we did the proper ventilation cutouts in the front and the rear to ensure good circulation, and ours is installed above an oven as well.

Thermador 36".

I have a 30" Electrolux induction. I linked the general page for the 36" model.

It's a 309X purchased locally. The dealer has been wonderful to work with even with all the issues

What are these? Ours is installed above a shallow 4" deep drawer. There is no obstruction to the the fans or intake vents.

We just came back from a quick trip to a different local appliance store that has the Diva on the floor. The salesman was an idiot - need I say more. I've forgotten more than he knows just from the research I did here and at the Induction site. The de Dietrich definitely cooks faster and dh likes the H warning for hot plates, too, which the Diva on the floor didn't have. The salesman tried to talk us into an Electrolux but couldn't tell us why that one other than price. We had to pull teeth to get him to look up the Viking and Wolf models.

I walked out and told dh I just had a bad feeling about the place.

I did write the GW website on a slip of paper and pass it on to someone else looking at appliances who I felt was getting a load of BS, though, so the trip wasn't all together unsuccessful LOL.

"What are these? Ours is installed above a shallow 4" deep drawer. There is no obstruction to the the fans or intake vents."

There may be no obstruction but if the cabinet is a sealed box ... In other words is there a hole/vent/whatever in the cabinet to allow air to come in? And somewhere for the warm/hot air to go to? (I have a Fagor over a F&P oven. A hole was cut in the cabinet side to a 3" filler which is open above the toekick. The Fagor vents out above the countertop at the back of the unit.)

We have a 30' Windcrest Induction over a F&P 30' wall oven. My DH also drilled extra holes into the adjoining cabinets to allow for additional ventilation.

This was not specified anywhere in the installation instructions, however we decided it couldn't hurt to have extra ventilation and it was no trouble to drill the holes.

We've only had our combo installed two days but I'm very pleased with both units so far.

There is a quiet clicking noise with the Windcrest as the pan heats but no other humming or anything. The fan is very quiet.

The cutout for the 30' model is 29 3/8 x 19 3/4.
The 36' model needs 35 3/8 x 19 3/4. Both require 2 5/8' below.

Windcrest has a website with more info.

I believe the ventillation cutouts to be more critical when the cooktop is installed over an oven, but the instructions in the De Dietrich manual were very clear about where to put the holes, how large, etc.

loves2cook4six,
I'm reviving this post to see what you've settled on.

My Dedietrich 308x has also developed a noisy habit. One of the fans sounds like a prop plane heard from a distance. We purchased the unit from Cookpower in New Zealand. It has worked great for more than one year, but this noise is scaring me.

Does yours make a similar noise?

piegirltoo, you should have a two or three year parts warranty on that cook top from Cookpower/Prestige Appliance. Give Prestige a call, as I'm not sure if Dennis is still with them, and ask them to send you out a replacement fan. That should probably do the trick!

We're one year on our De Dietrich 308X, also purchased from Cookpower, and so far it's working well. I've got my fingers crossed for years of happy, unfettered use!

Ooh, sorry to hear about your noisy cooktop-- sounds dreadful.

We have the Brandt from Cookpower and have been only happy with it. My understanding from Dennis is that Brandt, Diva and de Dietrich are all the same units, rebadged by different companies, so that may not help you.

Thanks sshrivastava and pecanpie.

I'll call Prestige. Sure hope they remember me!

We sure love this cooktop. It's been installed in 2 homes and shipped from afar, so I guess I shouldn't be surprised it's making noise. (It still works though!)
