Why is my pressure washer losing pressure

Understand that pressure washers like other cleaning machines tend to lose their full capacity and malfunction at one point or their entire life.  And if you’ve been using your pressure washer for a long time, it’s no wonder that your pressure washer starts to lose its pressure. But don’t worry, below are some of the troubleshooting tips you can follow.


Steps To Fix Pressure Washer Losing Pressure

If you’re worried why is my pressure washer losing pressure, here are the tips to troubleshoot a pressure washer that loses their pressure:


Step #1. Check the pressure washer hose

There are two types of hose—the power and garden hose. The power hose is the one that takes in the water from an outlet valve while the power hose delivers water into the wand.  Check whether there’s leakage or hose interchange, or an incompatible hose. Use the right diameter and pressure hose as they should properly be connected. However, if you’re not sure of the required diameter, it’s recommended to check the user’s manual.  If the pressure washer hose is worn out or faces total damage, then consider replacing it right away.

Step #2. Look to the nozzle and wand

Nozzles and wands are prone to dirt. Accumulated dirt can clog these parts. The clogged nozzle and wand will cause the machine to fail to deliver sufficient water and pressure, thus, affecting the functionality of your machine. To fix this, you just need to remove all the dirt in your wand and nozzle. In case your nozzle and wand are worn out and you cannot fix it, replace it instead. Consider some regular cleaning in the nozzle and wand as part of preventive maintenance. Here’s the pressure noozle chart


Step #3. Inspect some issues in the washer pump

Over a long period of time, your pressure washer may accumulate dirt, molds and minerals. Though the debris may not harm the pressure pump, dirt that accumulated over a long time may prohibit the sufficient water flow the pressure washer needs to work on properly. It is best to check the inline filter system. Remove the dirt with an air blow. Clean the washer pump regularly so that the pressure washer remains functional and safeguarded against any damages.

Step #4. Test if there is unnecessary air in the machine system

The pressure washer has different pipelines and hose fittings. For loosened hose fittings and unwanted air in the system, expect them to lose pressure in the machine.  Remember that unwanted air in the system is caused by a mixture of water and air. And this is not good for the system of the machine.  Avoid this unwanted air as the pressure washer requires air coming from the right channel.  To prevent any of this unwanted air, make sure to get fittings tightened and attached.


Step #5. Monitor the inline filter and water temperature

Keep in mind that the pressure washer depends on the condition of the water used. Some water is labeled as cold or hot in a water pressure washer. It is essential to use the right water in this case.  If you use cold water for a hot water pressure washer or if you use hot water for a cold water pressure washer, the machine will then bring about undesirable water pressure. To avoid this issue, check the pressure washer and its type. Do not make use of an incompatible water state to your machine.


Step #6. Read the user’s manual

Aside from the tips listed above, there are little tricks to consider so that the pressure washer runs at its full power. Turn off the power supply, let the water flow freely through the machine, and press the trigger of your spray wand.  Also, one of the most underrated and most basic tips that owners of pressure washers tend to forget is in checking out or reading the user’s manual. Read on to consider some simple instructions you might have missed causing you to encounter problems in using the machine.


It’s A Wrap!

Now you learn why is my pressure washer losing pressure due to some reasons such as an issue with the washer pump, a problem with the nozzle and wand, wrong pressure washer hose, wrong inline filter, insufficient air system, & water temperature.
