I am having problems with a 3 months smeg machine, its leaving marks on clothes after washing, this doesnt happen all the time its only every now and then, Smeg are saying there is nothing wrong with the machine. I can understand if its an old machine, but this is a new machine and everything is clean inside. Sorry i have tried to attach images here but it says images too big. I look forward to hearing from you on what might be causing this, by the way i use liquid detergent.
