Building in refers to changing a Kenmore portable dishwasher into a fixed, permanent dishwasher. This is not an option for all models, but many portable dishwashers can be converted. Manufacturers, realizing this, create and sell kits designed specifically for conversion. The first step in building in is buying one of these kits, preferably from Sears (the originator of the Kenmore brand) or from another brand that offers kits compatible with your model.
To build in your dishwasher, you need to choose the right spot in your kitchen. You need access to both water and electricity. Traditional kitchen structures make room for a dishwasher, with an opening in the counters with just these attachments. Create or use one of these openings for your portable dishwasher, and ensure there is enough room. Laying down carpet or a rug may help with noise reduction, but a rubber base may also work while keeping the floor more waterproof.
There are parts of your portable dishwasher you no longer need when building it in. If the top includes a cutting board or similar surface, remove it. Also remove the casters and wheels on the bottom of the dishwasher. You will need screwdrivers and wrenches to detach the panels and hoses in the back of the dishwasher so all fittings can be easily accessed. Unplug the power cord before you begin, and detach the water supply connections and the drain hose for the dishwasher in preparation.
The conversion kit comes with the necessary valves, pins, connectors and framework to attach your portable dishwasher water lines to the house lines, fully mounting the dishwasher. Follow your conversion kit instructions carefully -- they will show the order you need to use when making connections and how each part should fit with the others. Do not try to use the dishwasher until all connections have been made. Do not connect power or turn the dishwasher on until all other work is done.
