When the power washer does not turn on, it is either due to no water flow or no electricity going to the power washer. In other words, either a water or electrical problem.

Water-flow Issue

The first area to check is water flow. There must be water flow through the system for the unit to turn on. The water flow check is as follows:

  1. The high pressure hose, spray gun and lance must be connected to the power washer.
  2. The garden hose must be connected to the power washer using the garden hose adapter.
  3. Turn the water completely on at the water faucet.
  4. The power cord should not be plugged in.
  5. Squeeze the trigger on the spray gun.
  6. If there is water flow through the spray gun and lance shooting 10 – 25 feet, this confirms water flow is NOT the problem for the power washer not turning on.
  7. If there is no water flow, perform the following troubleshooting procedures:
    a. Remove the lance, squeeze the trigger. If water flows, the lance is blocked. Use cleaning wire to clean the nozzle tip and try again.
    b. If no water flows with lance removed, turn the water off. Remove the spray gun from the high pressure hose. Turn the water on, if water flows, the gun is the problem. Reattach the gun, turn the water on and squeeze the trigger. Sometimes this unblocks the gun. If not, replace the spray gun.
    c. If no water flow with the gun removed, remove the high pressure hose, turn the water on to make sure there is no blockage in the hose. This is very unlikely but we need to make sure.
    d. If no water flows out of the water outlet, the quick connect garden hose adapter is problem. See Garden Hose Adapter troubleshooting.

Applying chemicals in low pressure has two advantages. First, if the chemicals were applied in high pressure, they will splash off, resulting in wasted solution. Secondly, because chemical injection only works in low pressure, you can change from low pressure to high pressure at the wand, instead of going back to the unit to engage chemical injection.

The ratio that the chemical is diluted varies slightly from unit to unit. The most common ratios fall between 12:1 and 18:1.

You must NOT use any household bleach with your machine. By using them you will damage the seals and o-rings in the gun, wand, hoses and pumps.

DON'T. Hot water can cause damage to the o-rings and pump. Once water reaches 145°F, the thermal relief will activate. Note: some of our units have 160º F and 180º F max temperature pumps.

DON'T. Water that is drawn from a lake may contain debris that will cause the pump not to perform correctly. Also, it will shorten the life of the pump since they are not designed to draw water from a stationary source.

The recommended length is 100 feet. The unit will operate at lengths beyond this, but performance will somewhat decrease, and chemical injection may not operate satisfactorily.

Clogged nozzles can increase pump pressure and possibly damage the pump. Immediate attention is required.

1. Always disconnect your spray wand from the gun before cleaning your nozzles! 
2. Clear the nozzle with a small rigid piece of wire such as a paper clip. 
3. Flush the nozzle backwards with water. 
4. Reconnect the wand to the gun 
5. Restart the pressure washer and depress the trigger on the spray gun. 
If the nozzle is still plugged or partially plugged, repeat number 1-4.

If the previous procedure does not clear the nozzle, replace with a new nozzle.

1. Check the power supply and mains fuse.
2. Check the main switch and spray gun.
3. Completely unwind the cable drum.

In the following cases, please consult one of our service partners or contact is directly:
1. The pressure switch or control pistons are stuck.
2. The motor is overheating
3. The main switch is faulty

PSI stands for "pounds per square inch". It is a measure of the water pressure coming out of the pressure machine. PSI provides the "oomph" you need to lift dirt and grime.

GPM stands for "gallons per minute". It is a measure of water flowing through the pressure machine. GPM provides you the necessary quantity of water to wash it away. 

Multiplying PSI by GPM can give you the real measure of a pressure water's cleaning power.
