Front loading or top loading washing machine?

Prewash is used to remove any extra dirt there might be on the clothes. That is not the purpose here

What program did you use?

I thought some of the suggestions this repair guy mentioned are interesting. Won’t apply for top loaders but the decision to use a delicate cycle over a regular program decreases wear and tear on the machine. Not do as many as you can fit in the machine but few or just one at a time because the wet load will be less and this in turn puts less stress on the bearings and spider if you then use the slowest spin speed.

He’s got a thing against powder detergent because he’s had to fix machines where people didn’t use a suitable detergent designed for the machine.
