Troubleshooting

Turbidity sensor is the component that measures the amount of dirt in the water. The machine uses this data for the steps of Auto Pro-

gram (if applicable). If the proper data from the turbidity sensor cannot be received, Turbidity Sensor Error occurs. When the error

occurs, the program default will continue the program as heavy dirt level.

3Way / Multi Valve is the component that diverts the water flow between the upper and lower trays independently. It is driven by the

electronics and the position of the valve is measured by a feedback signal. Diverter Valve Position Error occurs if the proper position

signal could not be received from the valve. When the error occurs, the electronics drives the valve until proper position signal is

achieved.
