Sun Joe Pressure Washer Not Siphoning Detergent: 6 Reasons And Their Solutions
Sun Joe pressure washers work by siphoning detergent, and they use this detergent to remove tough dirt and grime. These pressure washers are very durable and don’t usually suffer from serious problems. However, in the long run, you can notice one issue: the Sun Joe Pressure Washer not siphoning detergent.
There can be a few reasons that can cause the pressure washer not to siphon detergent. The most common reasons include a block in the siphoning tube, high inlet pressure in the pressure washer, and a clogged nozzle. There can be other minor issues also, like a broken soap injector.
Hence if your Sun Joe pressure washer is having issues with detergent siphoning, then today’s guide is for you. Today in this guide, we will discuss everything you need to know about this issue and its fix.
Why is my Sun Joe Pressure Washer Not Siphoning Detergent
Even the best commercial pressure washers can occasionally experience issues, so don’t be concerned if your Sun Joe pressure washer does not siphon detergent. You may use the device without soap, but to get the most use possible out of the pressure washer, you need a proper flow of detergent.
Finding the source of these problems is crucial to fix them. Thus down below, we will talk about these problems.
- Blocked Siphoning tube
- Wrong Nozzle type
- Clogged nozzle
- Broken injector
- High Inlet pressure
- Concentrated soap
How To fix Sun Joe Pressure Washer Not Siphoning detergent Problem
By now, you already know the reasons that can cause detergent flow issues in your Sun Joe washer, and down below, we will discuss how you can easily fix all of these problems.
Clean the siphoning tube
The siphon tube gives the detergent a route to follow as it moves toward the nozzle’s tip. Over time this tube can get blocked by debris or filth that has stuck to it, which would stop the detergent solution from flowing through it.
Moreover, the tube you use can also be smaller in size than the required size, and it can also restrict the flow of detergent. As a result, no detergent will come out.
Use the proper size siphon tube initially to ensure an unhindered detergent flow. After that, thoroughly wipe the tube and check for any obstructions. Only use clean water to wash the tube’s two ends.
Change the nozzle
Some nozzles are made to apply soap, while others are not; they all have various functions. Therefore, picking the right nozzle type is crucial. If your soap injector does not appear to be working, it is quite probable that there is a significant accumulation of backpressure in the water flow that is running.
This prevents the detergent’s suction so that the pressure washer won’t siphon the detergent. So, you will need to change the nozzle type when this happens.
Check your user’s handbook to see the recommended nozzles for specific pressure kinds. The detergent injector should not typically be operated with high-pressure nozzles.
As a result, you should switch to a low-pressure nozzle, and the siphoning problem should be resolved.
Clean the nozzle properly
A nozzle or hose may easily become blocked with dirt and debris over time. Depending on the obstruction, a blocked nozzle can also lead to problems with high and low pressure and prevent the detergent from flowing smoothly. Fixing this issue is not that difficult. Read below to know more.
Simply unplug your spray wand, and rinse the nozzle by passing clean water through both ends. Then use a little piece of wire to clean out the nozzle and remove any dirt or any material that is blocking the flow.
Once cleaned, flush it with water. Reconnect the nozzle and check whether the issue has been resolved.
Fix the injector
Your detergent needs to be mixed and added to the Sun Joe pressure washer before it can be injected into your nozzle. This injection system is complex and made up of several small functional parts.
Therefore, it is almost hard to fix this on your own when it breaks. Therefore you must get expert help to fix the Sun Joe injector system.
Reposition the Valve
The injector won’t function if the inlet water jet comes in at high pressure, preventing detergent from being sucked up. This typically occurs when the water inlet valve is opened fully, generating a large increase in water pressure that prevents the injector from drawing detergent.
To fix this, you will need to reposition the valve; here, you will need to play with the valve position. Keep changing it until you see that detergent is coming out properly and that it is in the perfect valve position.
Dilute the detergent
It’s likely that your Sun Joe pressure washer and the pressure washer soap you’re using are incompatible. If the detergent becomes too thick, it won’t be able to sufficiently pass through the soap injection mechanism and spray nozzle after leaving the tank.
You should follow the specified detergent dilution ratio provided by your pressure washer manufacturer and make sure the solution is not too thick. Simply add some water to thin down the solution if it starts to get too thick to maintain adequate flow.
Frequently Asked Questions (FAQs)
Yes, water will siphon from a Sun Joe pressure washer. However, this relies on the kind of power washer you have and how recent it is compared to more recent versions that are more technologically advanced than earlier generations.
Ensure that the soap siphon setting or nozzle you are using is correct. For the proper application, see the manufacturer’s handbook. Shut the water supply valve gradually and spray soap until the foam from the detergent is apparent.
In most cases, if your Sun Joe pressure washer isn’t spraying soap, the water pressure is probably too high. This prevents correct sucking and blending. Use a low-pressure nozzle and make sure the hose and tube are free of twists and obstructions.
Conclusion
It can be quite annoying when your Sun Joe pressure washer is not siphoning detergent properly. Hence, today in this guide, we have discussed all the reasons that can cause this, along with how to fix them.
It is recommended that you properly maintain your pressure washer and all other components of it regularly to prevent any blockages or clogs buildup inside. Regular maintenance can help to prevent most problems with your pressure washers.
If your pressure washer still doesn’t siphon detergent after trying all the fixes we have discussed so far; then you must consult a professional mechanic.
