You work at XYZ manufacturers and a competitor has just released a rival washing machine...

This is a threat of a new entrant. The competitor has now entered the washing machine market and is competing directly with you. This is not a threat of substitution as it is the same product. A substitution would be if they invented a new product that washed clothes and people started buying this instead of washing machines.
