Estimating the wear of the single electrical parts of a home appliance without resorting to a large number of sensors is
desirable for ensuring a proper level of maintenance by the manufacturers. Deep learning techniques can be effective tools
for such estimation from relatively poor measurements, but their computational demands must be carefully considered, for
the actual deployment. In this work, we employ one-dimensional Convolutional Neural Networks and Long Short-Term
Memory networks to infer the status of some electrical components of different models of washing machines, from the
electrical signals measured at the plug. These tools are trained and tested on a large dataset (502 washing cycles 1000 h)
collected from four different washing machines and are carefully designed in order to comply with the memory constraints
imposed by available hardware selected for a real implementation. The approach is end-to-end; i.e., it does not require any
feature extraction, except the harmonic decomposition of the electrical signals, and thus it can be easily generalized to
other appliances.
