To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

The number on the end of the error code refers to which pump is having the issue. For example DKD#.

Pump was unable to reach it’s drive position.

Not enough air is supplied to the dosing valves

Ensure that at least 85 PSI is being supplied to the dosing valves.

Check for an obstruction downstream of the pump that would increase pressure. Ensure the feed pressure is within 1/2 – 1/3 of the target pressure.
