DA04 : Exceeded Maximum Flow Pump
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.
