Abstract
A parts washer including a receptacle positioned on a reservoir for cleaning liquid having a drain opening and a module which engages a portion of the reservoir in the cleaning liquid for adjusting the temperature of the cleaning liquid and circulating the cleaning liquid into the receptacle. The module includes a heating element, a sensor and pump. An enclosure houses a temperature controller which displays the temperature of the cleaning liquid and a low liquid level condition. A bridge thermally links the heating element to the sensor so that the sensor normally generates a signal representative of the temperature of the cleaning fluid unless the level of the cleaning fluid is disposed below the sensor.
