Sensor assembly

A coffee making machine comprising:

• a sensor assembly for determining a temperature and an orientation of a jug having a bottom surface to rest on the sensor assembly, the sensor assembly further comprising:
• a temperature sensor for producing a temperature signal indicative of the temperature of the bottom surface, the temperature sensor being urged to move in a first direction;
• a diaphragm, the diaphragm being sealingly engageable with the temperature sensor and a platform supporting the jug, such that the temperature sensor extends through the platform to engage the bottom surface;
• a retainer, the retainer being connected to the temperature sensor and limiting movement of the temperature sensor in the first direction;
• and
• a signal generator for producing a signal when the temperature sensor is moved against the urge to move in the first direction, wherein the signal generator is located adjacent the temperature sensor.
