No those gaps should not be there but who designed the kitchen I do not understand what you mean by mounting . Usually a DW slides in and at the front there is a place to attach it to the counter or to a piece of wood across the front like this and you also notice the very tiny gap on the side that the door covers.

He has screwed the dishwasher into the wood on the back and the side brackets aren't being used.

Normally the cabinets are built with enough space for the dishwasher to "slide" in and is secured at the front as per Patricia's post. With the counter already installed.

If/when your machine breaks down, they will have to pull the counter off to get it unscrewed from the back. You installed your dishwasher too soon. Where else could he secure it?

Have it removed and put back in when kitchen cabinets and counter are installed.

@angel the cabinets are already installed. Seems as the contractor secured the dishwasher improperly?

WTH... The dishwasher should be mounted either to the cabinet sides or to the underside of the counter, depending on counter material.

There shouldn't be a gap on the sides and that gap likely means the counter has been fabricated incorrectly. Also it likely means your door trim was cut incorrectly.

Yeah the door trim was definitely done incorrect. In our previous kitchen the cabinets didn't go over this far

my bad. Yes, he installed it improperly, but where else could he secure it?

He couldn't secure it to the sides and couldn't install it at the top.

Who designed the kitchen.

@angel why couldn't he secure it to the sides? The contractor "designed" the kitchen and ordered all the cabinets.

He couldn't secure to sides because contractor designed the space for the dishwasher too big.

Hence the big gaps each side. Best to ask him how he is going to fix the problem.

Have you double checked the measurements?

It looks like he installed the end piece too far to the left, leaving the gap too big. He may need to move that end piece to the right and replace the door trim.

If he screwed the dishwasher to the back wall, how will you ever change it without removing the countertop?

The fix might be to tear out the panel at the door and move it over so things fit "tight".

Yes he could have attached it to the sides if the sides were properly installed. There is no need to attach the dishwasher anywhere before the counters are installed, dishwashers don't wander into the other rooms or raid the fridge if you wait to secure them until after the counters are installed. I strongly suspect that the Bosch repair guy would simply refuse to repair it until it was unattached as that is not an allowed installation method.

Just Google the dishwasher's installation instructions to see the acceptable methods, I found them pretty fast.

I would like to add a third issue to @HALLETT & Co.'s list. The dishwasher mounting and the dishwasher cabinet are significant signs of incompetence. Dishwashers are the most standard appliance in the kitchen, even a DIY'er shouldn't mess that up. In my opinion, you need to hit the pause button and have someone check all his work.

Wow. That is a disaster waiting to happen. It needs to be pulled before that counter top goes on. The opening is too wide. The dishwasher installs with mounting brackets on the sides. Should be a tight fit. It is fixable, by moving the left piece in, but looks like the mounting rail in the back needs cutting down, the door trim will need replacing. Don’t let the countertops go in yet.

Is that a new back splash you have installed?

Just remove the dishwasher and install after the counter That rear mount is stupid. If the opening is too wide you will need the cabinet makers to makeshift trim it in. Its good that you asked before the countertop, I cant imagine the mess you would be in if were installed. Good luck

@angel yes it's new backsplash. I think we are going to have to pay someone else to fix everything he messed up. Sounds like the best option is to move over to the right and have the fabricators re-template?

Yes, that sounds like the best way. You will have to remove the tile down the right side of the door, re tile and new door trim. What about flooring? Is that going to be an issue? Have you paid him yet?

I hope you didnt pay in full. There are probably other things wrong. That backsplash may have to come off. Usually thats the last thing installed.

@angel yes he was paid in full unfortunately. He was well reviewed and recommended by a family member. We definitely overpaid in the end as he kept adding on additional cost. Flooring is installed and will also need to be fixed as there are spots they installed that wasn't level and places they over cut.

That's unfortunate. I'm sure you don't want him back to fix things. Your only recourse may be to keep your invoices for fixing everything and take him to small claims court. Get pictures of everything if you do go that route.

Have the family member over and show them the poor workmanship, so they don't recommend him to any one else. Where did you read the reviews? Perhaps you could put your own and include pictures. So sorry that your new kitchen is ending up being a nightmare.

@angel haha you're right I don't even want him to step foot in our house again. He's well reviewed on Google/thumbtack and will definitely be sharing my feedback

Have you cancelled the counter for now.

@angel waiting for them to call me back to see if it's possible to still install if we move end panel over to the right

Next time do not let a contractor act like a designer tjhey are not designers .

USA model dishwashers want 30 inches width; European about 3/8 less width. Accommodation for both can be had by making the gap 30 inches, and adding a trim piece if one is using a European model. It is essential for noise reduction that the rubber skirts on the sides have proper contact with the trim. And if that is done, then retention can be based on front side screws as it is supposed to be. Note that these screws should not be installed until the counter is in place and the dishwasher raised to its final position. As someone said above, get that unit out of there until the counter is installed, and shim the cabinet sides appropriately.

24-inches, as noted below. Early morning retardation, I fear.

It’s 24” not 30

Dishwashers have been standard 24" width for many years, other than a few specialty models such as Fisher & Paykel's 36" drawer units (no longer available). European brands are slightly less than 24" but typically are installed in a 24" space (filler gaskets are usually included to block sound transmission) to allow for a future change to a different brand.

"Get a tape measure and measure the width of the opening. It should be exactly 24”."

Correct, but it has to be a plumb 24", front and back, side to side. A perfect 24" parallelogram is useless. I doubt anyone stupid enough to screw into the back of a dishwasher knows this.

Update- in order to get our kitchen useable we are pushing dishwasher end piece over 1in which leaves a 24in gap for the dishwasher and the fabricator is taking 1in off the length of the marble.

Move the d/w over to the right and install properly. Move the end wall over to the right. Now you will have enough space for the countertop overhang even though only 1/2". That door would have come within a few millimeters from being blocked by the countertop. Very uncomfortable to have a countertop that close to the doorway. Normally you set cabinets back at least 6" from any door or opening and that is past the trim not the door opening. Replace the door trim that was cut out needlessly.

Great solution OP. Just putting fillers as some have suggested would not allow the dishwasher to be properly mounted from the side.

The contractor is a colossal idiot. Good lord, how many homes has he ruined?

Brittany that is the correct solution- will look better too. Sorry you’ve had so many issues. As joe points out do put a level on it too- we don’t trust your ‘contractor’

Did the marble guy come and do his own measuring ?

I would be checking everything just in case.

@angel they did the original measurements I did the remeasurements for that one piece for just the length as they are actually in the next state over. Hopefully it all works. We have enough extra marble that we could refabricate a piece in the future if necessary.

good to hear.

Just make sure you take rear screws out before the countertop is installed or you will never take the DW out.
