Find answers to frequently asked questions on selecting, owning, and operating a SilicaSlayer® battery powered sprayer.
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.

Tools Required: voltmeter, Phillip's screwdriver, pliers.

STEP 1: Check the battery.

a). Insert a charged, functional battery into the sprayer.

b). 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.

c). 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.

a). 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.

b). FOR VARIABLE-PRESSURE UNITS: If the dial rotates continuously, without a stopping point, replace the dial.

STEP 3: Check the microswitch.

a). 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.

b). 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.

c). 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.

d). 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 screwdriver.

STEP 1: Check for leaks from the gun.

STEP 2: Check for leaks from the hose and pump.

a). Unscrew the cover plate and remove. With water in the sprayer, start spraying and look for leaks.

b). If the sprayer is leaking where the hose connects to the pump, tighten the hose clamp.

c). If you notice a leaking from the pump diaphragm, replace the diaphragm/pump.
My sprayer won't shut off; the battery has to be removed to stop it.
STEP 1: For VARIABLE-PRESSURE sprayers -

a). Check if the pressure dial is rotating continuously with no stopping point. If so, the dial and circuit board must be replaced.

b). If the dial is functioning normally, replace the circuit board only.

STEP 2: For DUAL-PRESSURE sprayers -

a). 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.

a). Unscrew the cover plate and set aside.

b).Make an adjustment to the adjustment screw.
My sprayer has little to no pressure when spraying.
Tools Required: Phillip's screwdriver, flat-head screwdriver.

STEP 1: If the sprayer is new or has not been used in a while, back feed water.

a). With the sprayer turned off, remove the spray gun from the hose.

b). Under a faucet, allow water to drip into the hose until you have about three (3) inches of water in the hose.

c). Twist the spray gun back onto the hose and fill the tank with about one (1) gallon of water.

d). Turn the sprayer on and rapidly press and release the trigger.

STEP 2: Check the inlet filter.

a).With the sprayer turned off, unscrew the cover plate and set aside.

b). Loosen the hose clamp and remove the jumper hose attaching the inlet filter to the pump.

c). Holding the inlet filter from inside the tank, turn the inlet filter on the exterior counter clockwise until the two parts of the inlet filter have been disconnected.

d). Check all parts for debris.
