How to Troubleshoot a DP Airless Paint Sprayer?

Troubleshooting a DP Airless Paint Sprayer can lead you to several on-the-job quick fixes without having to take the rig to a dealer for repair, please follow below tips step by step.

1.Check the electrical connection and the on/off switch or pressure control knob if the motor does not turn on. Make sure the pressure control knob is set high enough for the unit to start pumping. If it doesn’t start and you are using an extension cord, unplug the extension cord and plug the sprayer directly into the wall.

2.Check your owner’s manual for the maximum length and correct gauge of cord you can use with your DP model; some won’t operate if the cord is too long or too small of a gauge. An extension cord that is too long can also cause the motor to overheat and stop running.

when you connect the sprayer with many other tools / machines with the same cord line, we recommend you to stop the other machines working when you spraying. Because the low voltage would cause problem for the airless sprayer machine also.

3.Remove and clean the filters if the DP sprayer runs, but doesn’t spray. The paint may also be too thick for the pump; thinning the paint with a pint of water per gallon should make it spray easier. if you are spraying the oil based paint, you need to put thinner to dilute it.

4.Make sure the tip is not plugged up by removing it and holding it up to the light to see if the filters are clean and the paint thin enough. If you cannot see through it, clean it with a toothbrush and hot water to remove the clog.

5.Check the paint level in the bucket or reservoir if the paint spits or comes out unevenly. If the paint level is too low, the unit will suck up air. If the paint level is good, try changing the spray gun tip nozzle. Tips wear out and need to be replaced periodically. Worn tips can make the paint spit and come out unevenly.

6.Remove the tip with a crescent wrench if it’s leaking. Make sure the tip washer and the atomizer valve are properly seated, replace the tip and tighten it securely. Some dripping is inevitable with thinner materials such as stains and clear coatings.
