Why does the washing machine smell?
Ans: All washing machines start to smell if they are left unused for a few days. The biological components of washing powders and liquids probably playa part in the smell situation, but variation between products should minimise the build up of any particular agent. An occasional hot wash should also keep it down, and keeping the door open won’t hurt. If the machine waste is connected under the sink, dirty water can go back into the machine in certain circumstances (back-syphonage), and that will cause exceptional smells.
