Certain dishwashers can hook up to kitchen sinks. A portable dishwasher is a full-sized appliance on wheels that a user can move around the kitchen. A countertop dishwasher is approximately the size of a microwave oven and sits on the counter.
Portable and countertop dishwashers come with special adapters to fasten the water and drainage hoses to the faucet. Installation of these adapters is simple and does not typically employ the use of tools, although a pair of pliers may be necessary to unscrew a tightened aerator. Once the adaptor is in place, the dishwasher can hook up to the sink following the manufacturer's instructions. The sink can also operate normally while the adapter is in place.
