This book contains basic information about the design of household automatic drum-type washing machines. A special feature of the book is its description of the operation of almost every component of the washing machine. The book also provides the minimum necessary information on troubleshooting simple (typical) faults. For the first time, materials on major repairs are presented: replacing bearings and seals. The technology for replacing brushes in commutator motors is shown. The appendix to the book contains some diagrams of both modern washing machines and those produced earlier. Using these diagrams, you can trace the evolution of the development of circuit technology for washing machines. The book is intended for a wide range of readers interested in the design of household automatic washing machines. The book will also be useful as a teaching aid for students of educational institutions of the relevant profile and for beginning craftsmen.
