  Brittany MolinaSep 4, 2025
  If your Lesco Paint Sprayer isn't turning on, first ensure the battery is correctly inserted and charged. Then, set the power switch to the ON position. If it still doesn't work, the battery may be damaged or overheated, in which case you should replace it or allow it to cool. Also, check if the hose is already pressurized, which might cause the pump to turn off automatically; open the shut-off to see if spraying starts.

How to troubleshoot a Lesco Premium Paint Sprayer pump that won't fully prime?
- B
  brandonmorganSep 12, 2025
  If the pump of your Lesco Paint Sprayer won't fully prime, first ensure that the liquid level in the tank is sufficient; add more liquid if it's low. If the pump was run dry before refilling, turn the power switch off, open the shut-off to relieve pressure, and then turn the power switch back on. Chemical residue buildup might also be the cause. In this case, clean the sprayer, and if necessary, repeat with warm water and mild detergent, letting it sit in the pump for up to an hour before rinsing. Also, check the in-tank filter; clean the sprayer and repeat the cleaning process if the filter is improperly installed, missing, or damaged.

  If your Lesco Paint Sprayer turns on but doesn't spray, the possible causes are: * The tank may be empty, so add liquid to the tank. * The shut-off may be clogged, so clean the shut-off. * The nozzle may be clogged, so clean the nozzle. * The pump may not be primed yet, so allow time for the pump to prime (up to 30 seconds).

  If your Lesco Paint Sprayer nozzle tip is leaking, has a poor spray pattern, a partial spray, or is completely stopped, it could be due to a missing or damaged flat seal or a clogged spray extension or nozzle. Replace the flat seal at the extension tip using Kit #7. Also, remove the nozzle and clean it as described in the Nozzle Maintenance section.
