<p>A turbidity sensing mechanism (25) for a dishwasher is connected in the fluid circulation conduit (18) between the pump (17) and the spray mechanism (19). The mechanism includes a hollow housing enclosing a hollow transparent tube connected in fluid flow relationship with the conduit. A source of electromagnetic radiation and a radiation-to-frequency sensor are positioned inside the housing on opposite sides of the tube.</p> |
