Coffee machine - Breville Bambini Plus

Breville Bambini Plus coffee machine. Four years old. Well loved. Started to fail two weeks ago. Needs a flush every couple of cups of coffee and then works again. We replaced it this weekend and would prefer to sell it to someone who is interested in fixing it, rather than sending it to landfill. The replacement was $729. Selling for $100. Pick up only (Ainslie).
