Don’t overload it, as you will only shorten its life
If you overload your washing machine’s drum, it will lead to less than perfect wash results, and might in fact damage your machine. Washing machines are made to wash a specific weight of clothes.
While it’s true that the type of laundry might vary, you can usually wash more cotton, such as bedsheets, rather than synthetics, like a gym kit.
There are many modern machines that won’t let function properly when you overload them. The machine won’t work if there’s too much in the drum, or even too much for the wash program that you’ve just selected.
