Knowledgebase: Technical Help
Why does the pressure fluctuate on my pressure washer?
 
> Water flow may be restricted to the pressure washer.

> Check that all hoses are free of kinks, leaks, or blockage. Make certain all hoses and fittings are connected properly. Make sure to open the faucet/spigot to full force. Set the spray wand to high pressure.

> Clear any debris from the nozzle.

> If the basics have been checked and the washer is still fluctuating from high to low pressure there may be air trapped in the pump. Repeating a process of allowing the water pressure to build up and then releasing the water pressure may eliminate this problem. This process allows trapped air inside of the pump to escape.
