PURPOSE: A hardness measuring apparatus of a washing machine is provided to prevent epoxy from discharging through a gap between an electrode sensor and a sensor hole during a process of hardening melting epoxy after injecting into a housing. CONSTITUTION: A sensor housing(56) prevents washing water from leaking, installed to a side of a tub. An end of an electrode sensor(60) penetrates a side of the sensor housing. The electrode sensor senses hardness of washing water of the tub. An inner portion of the sensor housing is filled with epoxy(62). A preventing device(64) of outflow is installed to a side of the electrode sensor to seal a gap(b) between the electrode sensor and the sensor housing. Therein, the preventing device of outflow prevents melting epoxy from discharging through the gap. |
