Why Does My Electric Pressure Washer Keep Cutting Out?

1.Power Supply of Your Pressure Washer

Certainly! Here’s the paragraph with the important points highlighted:

The power supply is one of the most important components of your electric pressure washer. If there is an issue with the power supply, it can cause your pressure washer to shut off unexpectedly.

Firstly, make sure that your pressure washer is getting enough power from its outlet. Ensure that you are using a properly grounded outlet and not using any extension cords or adapters as this can reduce the amount of power reaching your machine.

Another common issue with power supplies occurs when there’s a fault in the wiring system. The wiring may have been damaged during use or while storing away which could be causing problems for the operation of your machine.

It’s also possible that overheating could be caused by insufficient voltage being supplied to run certain parts of your pressure washer like its motor and pump systems. Always ensure that you follow proper instructions provided by manufacturers regarding suitable generators or RCDs if needed.

If you suspect an electrical problem with your pressure washer, always consult a professional electrician who will inspect and provide diagnosis on any issues affecting operation before continuing use to prevent personal injury and damage to property.

2.Incorrect Start-Up Procedure

If you’re experiencing issues with your electric pressure washer shutting off soon after start-up, one of the possible culprits could be an incorrect start-up procedure. This is a common mistake that many people make when using their pressure washers for the first time.

One mistake some people make is failing to properly connect and turn on the power supply before starting up the machine. Make sure to read your user manual carefully and follow all instructions regarding setting up and powering your washer.

Another common error is allowing air pockets in the hose by not fully priming it before turning on the machine. To avoid this problem, simply run water through your pump until no more air bubbles come out of the nozzle.

Also, ensure that your spray wand or gun isn’t in use during start-up as this can cause damage to internal components if water isn’t flowing correctly.

By following these basic steps for proper start-up procedures, you’ll help prevent any unnecessary shutdowns caused by simple mistakes like these.

3.Leaking Hose

A leaking hose can be a common issue that causes your electric pressure washer to keep cutting out. The first thing you need to do is check the connections between the hose and the machine. If they are loose, tighten them up or replace any damaged parts.

Another potential cause of a leaking hose could be due to wear and tear over time. Hoses can become brittle and crack, which results in water seeping through the gaps. In this case, it’s necessary to replace the entire hose with a new one that matches your pressure washer model.

If you have an adjustable nozzle on your pressure washer wand, make sure it’s not set too high as this can put unnecessary strain on the hoses leading to leaks.

Always ensure that you’re using a clean water source without debris or dirt that may clog up your pressure washer system causing damage over time including leaky hoses.

By addressing these issues related to a leaking hose promptly, you will help prevent further damage from occurring and keep your electric pressure washer running smoothly for years!

4.Insufficient Hose Diameter

One common reason why electric pressure washers keep cutting out is due to an insufficient hose diameter. This means that the hose connected to your pressure washer is too narrow, which restricts the flow of water and reduces the machine’s overall performance.

When there isn’t enough water flowing through your pressure washer, it can cause a drop in pressure, leading to frequent shutdowns. Often, this issue occurs when you try to use a long or heavy-duty extension cord with your machine since these cords tend to reduce power output.

To avoid this problem from happening again, ensure that you’re using a hose with adequate diameter based on your machine’s specifications. This information should be included in the user manual if you don’t already know what size is appropriate for your device.

In addition, always make sure that any extensions or attachments are compatible with both the hose and the unit itself. Doing so will not only prevent frequent shutdowns but also improve cleaning efficiency while prolonging its lifespan.

5.Unloader Valve Fault

The unloader valve is a critical component of the pressure washer, responsible for regulating the flow of water through the system. When it becomes faulty, your electric pressure washer can keep cutting out after a few minutes.

One common issue with the unloader valve is that it can get stuck in its closed position due to dirt or debris buildup. This prevents water from flowing through, leading to an overload on the motor and causing it to shut down automatically.

Another possible cause of an unloader valve fault is wear and tear over time. The constant opening and closing of the valve can lead to damage or corrosion, which affects its ability to function properly.

If you suspect that your pressure washer’s unloader valve is faulty, there are several steps you can take. First, try cleaning it using a specialized cleaner designed for this purpose. Alternatively, if cleaning doesn’t work or if there’s visible damage on the part, consider replacing it with a new one.

6.Problems with Water Pumps

One of the most common reasons why an electric pressure washer keeps cutting out is due to problems with the water pump. The water pump is responsible for drawing in and pressurizing water that’s coming from your household supply or other sources.

One issue that can arise with a faulty water pump is low pressure, which can cause the motor to shut off automatically as a safety feature. This could be caused by worn or damaged parts within the pump itself, such as seals or valves.

Another problem that may occur with a malfunctioning water pump is excessive noise during operation. If you hear unusual sounds coming from your machine when it’s running, this could indicate an issue with the internal workings of your water pump.

It’s important to address any issues with your pressure washer’s water pump immediately to prevent further damage and ensure optimal performance. Regular maintenance and inspections of all components can help identify potential problems before they become major issues.

7.Clogged Filters

Clogged filters can also cause your electric pressure washer to cut out. These filters are responsible for preventing dirt and debris from entering the machine’s internal components. When they become clogged, water flow is restricted, causing the motor to overheat and shut down.

To prevent this issue, it is crucial to clean or replace your pressure washer’s filters regularly. You should check the manufacturer’s instructions on how often you need to do this based on your usage frequency and intensity.

To clean a filter, remove it from the machine and rinse it thoroughly with water until all traces of dirt are gone. If it’s too dirty or damaged beyond repair, consider replacing it with a new one recommended by the manufacturer.

Some models have more than one filter in their system like inlet screen strainers that can be located at either end of an intake hose or built into a pump head. Ensure that all these filters are cleaned regularly because even if one of them becomes clogged, pressure will drop as well resulting in frequent interruptions during cleaning tasks.

By taking care of your electric pressure washer’s filters properly, you’ll not only prevent shutdowns but also extend its lifespan while maintaining optimal performance levels throughout its life cycle.


One of the common reasons why your electric pressure washer keeps cutting out is overheating. When the motor gets too hot, it shuts down to prevent any damage. Overheating can happen for several reasons.

Firstly, if you are using your pressure washer for an extended period without giving it a break, it might overheat. It’s crucial to take breaks during use and allow the machine to cool off before restarting.

Another reason could be that there isn’t enough airflow around the motor or pump unit. Make sure that nothing is blocking or covering any vents on the machine.

Additionally, if you’re using a high-pressure nozzle with a low PSI rating pump, this can cause overheating due to excessive strain on the system.

Check that your water supply has ample flow rate as insufficient water supply can lead to overheating since there won’t be enough coolant circulating through the system.

Prevention of overheating involves regular cleaning and maintenance of all parts involved in cooling such as filters and fans while also keeping track of temperature gauge readings when operating at maximum capacity.
