If you own a Sun Joe pressure washer, you know how handy it can be for cleaning various surfaces around your home. However, it can be quite frustrating when your pressure washer keeps shutting off unexpectedly during use. There are several reasons why this might be happening, and understanding the underlying causes can help you troubleshoot and fix the issue.

One possible reason for your Sun Joe pressure washer shutting off is a clogged nozzle or spray gun. Over time, dirt, debris, or mineral deposits can accumulate in these parts, restricting the flow of water and causing the motor to shut off as a safety measure. To remedy this, you can try cleaning the nozzle and spray gun with a small brush or using a pin to clear any blockages.

Another common cause for your pressure washer shutting off is an insufficient water supply. If the water source is not providing enough water pressure or volume, the pressure washer’s motor may shut off to prevent damage. Ensure that the water supply is fully turned on and there are no kinks or obstructions in the hose. You can also check the water inlet filter for any blockages and clean it if necessary.

Additionally, a faulty thermal overload switch can cause your Sun Joe pressure washer to shut off. The thermal overload switch is designed to protect the motor from overheating by shutting off power. If the switch is defective or damaged, it may trip too easily and shut off the motor prematurely. In this case, you may need to replace the thermal overload switch to resolve the issue.

By identifying the possible causes for your Sun Joe pressure washer shutting off, you can effectively troubleshoot the problem and ensure smooth operation. Regular maintenance, such as cleaning the nozzle and spray gun, checking the water supply, and inspecting the thermal overload switch, can help prevent future shutdowns and prolong the lifespan of your pressure washer.

An inadequate water supply can also cause your Sun Joe pressure washer to shut off unexpectedly. Ensure that the water supply valve is fully open and that there are no kinks or blockages in the hose.

If your pressure washer lacks pressure or shuts off when you release the trigger, it may have pump issues. Check the pump for any leaks, obstructions, or damages. Clean or replace the nozzle if it’s not delivering enough pressure. Additionally, ensure that the pump is properly lubricated and that the oil levels are adequate. Consult the manufacturer’s manual for specific instructions on maintaining and troubleshooting the pump.

5. Safety Features

Sun Joe pressure washers are equipped with various safety features that may cause the unit to shut off under certain conditions. For example, if the trigger is not engaged within a certain timeframe, the pressure washer may automatically shut off to prevent overheating or damage. Refer to the user manual to understand the specific safety features of your pressure washer and ensure that you are using it correctly.

In conclusion, while Sun Joe pressure washers are generally reliable, they can encounter common issues that may cause them to shut off. By troubleshooting power supply, water supply, overheating, pump issues, and understanding the safety features, you can resolve these problems and keep your pressure washer running smoothly.

2. Clean the inlet filter

The pressure washer’s inlet filter may become clogged with dirt, debris, or residue, leading to a restricted water flow. Turn off the pressure washer and remove the filter. Clean it thoroughly under running water, removing any built-up dirt or debris. Once clean, reattach the filter securely.

Check for any signs of wear, such as cracks or blockages, and replace the nozzle or lance if necessary. Ensure that the nozzle or lance is securely attached to the pressure washer.

4. Avoid overloading the pressure washer

Using the pressure washer beyond its recommended capacity can cause it to overheat and shut off as a safety measure. Consult the user manual for your specific Sun Joe pressure washer model to determine its maximum capacity. If you’re unsure, start with lighter cleaning tasks and gradually increase the workload.

5. Maintain proper engine oil level

Check the oil level in your pressure washer’s engine regularly and ensure it is filled to the recommended level. Insufficient oil can cause engine problems and lead to shutdowns. Follow the manufacturer’s instructions for oil type and recommended oil change intervals.

6. Keep the pressure washer clean and well-maintained

Regularly clean the pressure washer to remove dirt, grime, and debris that can accumulate and hinder its performance. Inspect hoses, fittings, and connections for any signs of leaks or damage and repair or replace them as needed. Proper maintenance and cleaning will prevent issues that could lead to the pressure washer shutting off unexpectedly.
