Electrical and electronic equipment is the fastest growing waste stream globally, and large appliances such as washing machines significantly contribute to this environmental problem. Therefore, we look into maintenance as a practice to improve the lifecycle and circularity of washing machines. To inquire into maintenance practices, we undertook the development of a series of prototypes with a constructive design research approach. The design of the prototypes incorporated nudge and persuasive technologies as part of the inquiry. We present this inquiry for understanding the gap between an everyday engagement with the washing machine and the necessary maintenance practices for prolonging the use and durability of these appliances. The final prototype, OptiWash, is presented not only as an object that characterizes this gap but also as a device for facilitating the everyday maintenance of washing machines and thus, prolonging the equipment lifespan and minimizing waste of electrical and electronic equipment.
