To add an integrated or built in appliance, such as a dishwasher, oven, microwave, you must first add a cabinet from a furniture catalogue that has a niche in it to enable integration.
You can use the filters to help you find a suitable cabinet from your selected catalogue.
Once you have placed the cabinet you will be required to select the integrated appliances. You are able to select the appliance catalogue from the drop down arrow next to the catalogue name.
Note: if you skip this step you can subsequently add the appliance to an empty niche see article Integrating a built-in appliance into an empty niche
