Planning an Ikea Metod kitchen with third-party appliances

That works, but you do have to tinker a bit.
My Neff machine is an XL, meaning, as you can see in the pictures, the entire unit is 90 high.
In front of the door, I have installed three fronts: 40cm, 20cm, 20cm.
And underneath that, a 10cm one, but that is fixedly installed.
And to make it work, you might need to attach an additional base plate under the machine.
The machine is height-adjustable via swivel feet, but that is not necessarily enough.
In my opinion, though, it’s worth the effort, because then the dishwasher is integrated and fits perfectly with the other fronts.

For an 86 cm high dishwasher with a Vario hinge, no Behjälplig is needed. In another thread, a trouble-free successful installation was reported for a model from Siemens.
