SCENARIO: Thomas is a restaurateur in Sydney Australia and is opening a new bakery business specialising in muffins. He visits Kitchen Warehouse Pty Ltd, who specialises in selling commercial kitchen equipment, to purchase a new commercial grade oven costing $20,000. Thomas tells Kitchen Warehouse Pty Ltd that he needs the oven to be able to cook three trays of muffins every hour for 8 hours to meet the demands of the morning rush at his new bakery. He is advised that the oven "CookWell" is a new model that is suitable for his new business and his needs.

The oven is installed in Thomas's bakery but when he uses it on the first day, he finds it can only cook two trays at a time and it overheats after four hours. The bakery cannot keep up with demand and is losing customers and money rapidly.

QUESTION. What are the primary issues here and which consumer guarantees have Kitchen Warehouse Pty Ltd breached under the Australian Consumer Law.
