Paint Sprayers are designed for a limited number of gallons/year of use, and will eventually stop spraying - motor dead or a simple fix? Follow these troubleshooting guides to figure out your sprayer's issue.
Pressure is Set to Zero
Adjust the pressure control knob or regulator to increase the pressure setting.
Outlet Stops Providing Power
Power surges can cause a breaker or GFCI to trip.
- Check to make sure that the cord is still plugged in.
- Try another outlet that you know works. If the new outlet works, then the circuit breaker or breaker box might have tripped from too many appliances running simultaneously. Reset the breakers and try starting the motor again in the original outlet.
Reset Tripped
Your device may also have its own reset button. Try depressing or resetting this (often) red circular button.
Internal Fuse Blown
If your device has an internal fuse, check and replace it if it's blown. Avoid using a small gauge and long extension cord - usually 12 gauge or larger. Avoid running the sprayer while the system is clogged in the tip of the spray gun, intake strainer, valves, or with too thick a material.
An electrical short caused by fluids on the electronics can trip the fuse. Unplug the cord and allow for electronics to dry.
Electrical Cord is Damaged
Examine the power cable and extension cable for any cuts, rips, or heat damage to the insulation or inner wires. Replace the cord immediately if wires are exposed or if there are missing ground prongs.
Thermal Overload
Check that the vent holes to the enclosure aren't plugged and the sprayer isn't covered.
The motor may have a thermal overload switch that shuts down if overheated. Hold your hand near the motor and feel its temperature. If hot, allow 45 minutes for the motor to cool before restarting.
In some cases where the sprayer was operated at high pressure with a very small tip, frequent motor startups can cause excessive heat buildup.
Frozen Water or Hardened Paint in the Pump
Unplug the sprayer from the outlet. Move the sprayer to a warm room to completely thaw if it's frozen. After several hours, plug in the power cord and turn the sprayer on. Slowly increase the pressure setting from zero and see if the motor starts.
If the paint is hardened in the sprayer, the pump packings, valves, drivetrain, or pressure switch may need replacing. Contact your service provider for available parts.

In the case where there is a reset button, try pressing it. Check the outlet and breaker to make sure they are still receiving power.

What do you mean when you say it stops working? Is the trigger lock on, and did you prime the pump?
Here's a troubleshooting manual for the Graco QuickShot.
