General Troubleshooting
My sprayer is not turning on and there is no sound coming from the pump.
If your sprayer is unresponsive, there are a number of areas that may be the source of the problem. Watch the video below to learn about common issues and the steps required to resolve them.
Insert a charged, functional battery into the sprayer.
If you don't have a spare functional battery, press the indicator button on your battery. If no LED lights appear or if the lights are red, the battery must be replaced.
A voltmeter can be used to check the battery in question. Turn your voltmeter to 200V DC. Hold the positive electrode on the positive battery terminal and hold the negative electrode to the negative battery terminal. It should read close to 18V. If there is there is a low or zero reading, the battery must be replaced.
STEP 2: Check the pressure dial/rocker switch.
FOR DUAL-PRESSURE UNITS: unscrew the cover plate and set aside. Unscrew the strain relief fitting. Using pliers, disconnect the spade fitting from the power switch and move to the neighboring extra set of wire contacts. Test the sprayer.
FOR VARIABLE-PRESSURE UNITS: If the dial rotates continuously, without a stopping point, replace the dial.
STEP 3: Check the microswitch.
Locate the microswitch housing (shaped like the letter "P") at the bottom of the pump. Remove the top and bottom screw from the housing to reveal the microswitch.
Using pliers, remove the connection that sits the furthest away from the pump. DO NOT PULL ON THE WIRE; squeezing the tab while pulling on the connector will release the pin and it should come off with ease.
Insert a battery into the sprayer and turn the power on. Bypass the microswitch by touching the disconnected terminal to the terminal that is still connected to the pump. Note: you may need to pull down the see-through rubber insulators to ensure metal-to-metal connection.
If this test causes the pump to turn on, you have a defective microswitch. If this test does not activate the pump and you know your battery to be functional, you likely need a replacement circuit board.
My sprayer continuously turns on and off without the trigger.
Tools Required: Phillip's head screwdriver, flathead screwdriver.
STEP 1: Check for leaks from the gun assembly. STEP 2: Check for leaks from the hose and pump.
Unscrew the cover plate and remove. With water in the sprayer, start spraying and look for leaks.
If the sprayer is leaking where the hose connects to the pump, tighten the hose clamp.
If you notice a leaking from the pump diaphragm, replace the diaphragm/pump.
STEP 3: Make changes to the adjustment screw.
Stand the sprayer upright and fill the sprayer with a bit of water. Turn it on.
Locate the microswitch housing (shaped like a "P") at the bottom of the pump.
Use a phillip's head screwdriver to tighten or loosen the adjustment screw (located between the two screws holding the microswitch housing in place) up to one full turn.
Activate the sprayer's trigger to test the response. Keep making adjustments until the trigger performs appropriately.
STEP 4: Check the pressure dial.
If you have a variable-pressure unit, try turning the power dial. If it rotates continuously, the dial will have to be replaced.
My sprayer won't shut off; the battery has to be removed to stop it.
STEP 1: For VARIABLE-PRESSURE sprayers -
Check if the pressure dial is rotating continuously with no stopping point. If so, the dial and circuit board must be replaced.
If the dial is functioning normally, replace the circuit board only.
STEP 2: For DUAL-PRESSURE sprayers -
Replace the circuit board.
My sprayer runs constantly without activating the trigger.
Tools Required: Phillip's screwdriver.
STEP 1: Check the trigger for leaks. STEP 2: Check the adjustment screw.
Unscrew the cover plate and set aside.
Make an adjustment to the adjustment screw.
My sprayer has little to no pressure when spraying.
With the sprayer turned off and battery removed, set aside the tank lid and intake filter.
Locate the inlet filter near the bottom of the tank. Gently twist and pull the inlet filter to remove.
Check the inlet filter for any debris or buildup.
To clean the inlet filter, rinse it with fresh water until all buildup is cleared. Then, wipe it with a clean cloth.
STEP 2: If the sprayer is new or has not been used in a while, back feed water.
With the sprayer turned off, remove the spray gun from the hose.
Hold the end of the hose pointing upward in a container of fresh water and repeatedly bend the hose to push any air out while taking water in.
Once around three inches of water has entered the hose, remove it from the water and reinstall the spray gun.
Fill the sprayer tank with a gallon of clean water, turn the sprayer on, and rapidly squeeze and release the spray gun trigger.
STEP 3: Check entire inlet filter.
Remove the cover plate using the Phillip's head screwdriver.
Taking the flathead screwdriver, loosen the hose clamp securing the jumper hose to the inlet filter.
Disconnect the jumper hose and hose clamp from the inlet filter. You may need to remove the screws securing the pump in place to fully detach the jumper hose.
Hold the inlet filter from inside the sprayer tank and turn the exterior part counterclockwise until the two parts separate. It may be helpful to use a wrench to turn the inlet filter.
Check all parts of the inlet filter for debris and clean if necessary.
Replacing Parts
Replacing the circuit board.
Tools Required: Knife, Phillip's head screwdriver, pliers.
Make sure the sprayer is off and the battery has been removed. Taking your screwdriver, unscrew the cover plate. Loosen the strain relief fitting and set the cover plate aside.
Unscrew the battery holster and detach it from the sprayer tank. Using your fingers or a pair of pliers, gently remove the wires connected to the battery holster.
To access the wires underneath the pump, loosen the screws securing the pump to the tank.
Using the knife, carefully slice the protective tape surrounding the pump-to-circuit board connection. Disconnect the circuit board from the diaphragm pump and slide the wires out from under the pump.
Disconnect the circuit board from the power dial in the same fashion by slicing the protective tape.
Follow the previous steps in reverse in order to connect the replacement circuit board. Connect the power dial, connect the pump and slide the wires under. Secure the diaphragm pump back to the sprayer tank.
Attach the wires to the back of battery holster while taking note of the color of the wires. Red = positive; black = negative.
Place the battery holster back into position and secure it.
Insert a battery into the holster and test it. If the sprayer starts up normally, you may close it up.
