Why does my Duro Water Filtration System show [Err 2]?

  The [Err 2] error on your Duro Water Filtration System indicates that more than 99 days have passed since the last regeneration. If you have selected the Day of the Week regeneration mode, this error appears if it has been more than 7 days since the last regeneration and all individual day settings (d1, d2, d3, d4, d5, d6, d7) are set to 0. To fix this, you must initiate a regeneration or set at least one individual day to 1 for the unit to recover, the display to clear, and the valve to function normally.
