just the cold setting .if you add too much hot ,it will casue too many suds
*Cold water temperature would be as cold as the ambient temperature outside, could be as low as 15 C which is OK for washing dark coloured fabric and light soiling.
* Auto temp is probably warm (can be checked with a thermometer or by feel) - would give you a better wash and easily dissolve the washing powder.
Remember always dissolve your powder before adding cloths to washer (you’ll increase your fabric life).
Good luck!
