How do I test my pressure washer for problems?
[Back to top] Diagnosing By Symptom No matter what the symptom, diagnosing a pressure washer usually follows this order:
- Check the power supply.
- Check the water supply.
- Inspect all hoses.
- Take a look at the inlet valve.
- Check the intake filter.
- Inspect the nozzle.
- Inspect the gun.
Why is my pressure washer not putting out pressure?
Nozzles. A common cause for lost water pressure is when the nozzle at the end of the trigger-wand becomes worn or plugged. An uncommon spray pattern may be an indication that there is debris blocking the nozzle. Nozzles that are wearing will usually cause a gradual loss in pressure, as opposed to happening suddenly.
Why does my pressure washer keep pulsing?
Check For Minor Problems Including Kinks Or Blockages If the water flow is restricted, there will definitely be surges and lapses in pressure. A dirty inlet or discharge valve is the most common cause of a pulsating pressure washer. Dirt or hard water can get caught up in these little divots.
How does a pressure washer check valve work?
Pressure washer check valves let enough water flow through the pump and manifold to pressurize the water at the nozzle. If the pressure washer check valves are damaged, the pump won’t build pressure. Air in the inlet water supply can damage the pressure washer check valves, as can chemical residue left in the pump.
What does a boost valve do on a pressure washer?
A pressure washer unloader valve diverts the water flow through the bypass when the trigger on the gun is depressed. The Unloader valve is designed to respond to an increase in pressure or a change in water flow. The unloader valve can also be used for adjusting the pressure of your machine.
How do you purge air from a pressure washer?
To bleed the pump of any air, turn the machine off and disconnect the high pressure hose and trigger gun from your power washer. With only the garden hose connected to the machine, turn on your water source and allow water to run through the pump of the machine for 20 or 30 seconds.
How do I get more pressure out of my pressure washer?
To reduce the impact pressure, simply step back from the area being cleaned. Some gas pressure washers have a pressure regulator on the pump. You simply turn the dial to increase or decrease the pressure. Others have a regulator on the spray wand, similar to the Vario wand on our electric power washer.
Why does my jet wash pulse?
Water flow may be restricted to the pressure washer. Check that all hoses are free of kinks, leaks, or blockage. If the nozzle has even a little bit of dirt in the tip, it may cause enough obstruction for the pressure washer to pulsate. If your pressure washer came with a nozzle cleaner, use it to clean the tip.
Why is my jet wash not powerful?
A: With the high pressure hose removed from the pump, attach the garden hose and turn on water. If this does not happen there is an internal pump issue. If this does happen then there is likely a clog in one of the attachments; high pressure hose, gun, wand, or nozzle.
