Here Are The Solutions If Your Bosch Pressure Washer Keeps Cutting Out!
Are you perplexed as to why your Bosch pressure washer keeps crashing? The majority of pressure washers exhibit these symptoms after extended use, so the issue isn’t specific to Bosch models.
There are many potential causes for your pressure washer to keep cutting out, including a faulty valve, a leak in the hose, a loose hose connection, a leak in the power supply, etc.
Whatever it may be, we’ll talk about the most typical causes of a pressure washer that keeps cutting out in this article.

This guide is essential if you’re worried about your Bosch pressure washer frequently cutting in and out and want to stop it. There are many causes for this, as we have already mentioned, but we will focus on some of the most prevalent ones.
Faulty Power Connection
The majority of the time, a bad power connection is what causes the pressure washer to shut off. Now, there are numerous potential causes for a bad power connection, including a loose connection, a bad wire, using a cable with a lower AMP rating, etc.
It is common to get carried away when using a pressure washer and overextend the power cable, which can interrupt the power. A slight pull on the cable plug can turn off the power supply; the plug doesn’t have to be completely removed from the electrical socket.
Most manufacturers advise using an extension cable no longer than 10 to 13 meters because a longer length may occasionally cause the machine to lose power.
Additionally, you must confirm that the cables you use have the recommended AMP rating. A pressure washer that has a lower AMP rating may abruptly shut off.
Any pressure washer, regardless of brand—Bosch, Panasonic, or Dewalt—can experience this type of issue.
Air Block in the System
This occurs when the pressure washer hasn’t been used for a while. Long-term sitting causes air to enter pressure washer systems, which, despite seeming like a minor problem, can permanently harm the machine.
The washer cutting out is the most typical sign that there is an air block in the machine. You need to bleed the machine in order to fix it.
Taking the air out of the system is the process of bleeding. Here’s how to do it:
Additionally, if the unloader valve is stuck, the pressure washer may shut off while it is in use.
Hose Leak
Make sure there are no leaks by thoroughly testing the garden hose that is attached to a water faucet. The motor will cycle if the hose leaks because it won’t be able to pump out enough water, which could result in pressure cutting out.
Check to see if the hose isn’t also blocked. We’re not referring to a hose that is completely blocked and obvious.
The waterway in the hose becomes partially blocked over time by dirt and grime, which prevents the washer motor from pumping the required volume of water.
Faulty Water Pump
Low water pressure may be caused by the water pump itself leaking oil or water. To find out, you should tighten all of the bolts and properly seal the pump so that it stops leaking. It’s time to visit the mechanic shop if you still notice that it is dripping water or oil.
If the pressure washer is still covered by warranty, speak with the manufacturer.
Overheated Motor
Long-term use of an electric pressure washer outside in the sun can cause the motor to overheat. Additionally, as the pump warms up, it has to work harder to draw water, which leads to the pressure washer cutting out.
Avoid operating a pressure washer for an extended period of time in the sun because the intense heat could burn the motor. Remove the plug from the power outlet, put the machine in a shaded area, and let it cool down if you smell anything burning or notice that the motor is heated up.
