DA02 : Exceeded Maximum Flow Pump

The number on the end of the error code refers to which pump is having the issue. For example DA0#.

Pump was driven to its maximum allowed speed.

System has a leak or open valve that is allowing unrestricted flow

Inspect system for leaks.

Pump is cavitating, cycling without restriction

Verify that the pump is being supplied with material.

Viscosity of material is too thin for nozzle size

Reduce nozzle size to create more restriction.
Reduce paint pressure to lower the flow rate.

System pressure or Flow Setpoint is too high (causing the pump to work too hard)

Reduce the pressure or the Flow Setpoint.
