Pressure washers are a pretty handy tool to remove the most stubborn type of dirt from your vehicle or machine’s body within a few minutes, aren’t they?
But, as you’re reading this article, you’re most probably encountering a problem of “low or no pressure” while using your homelite pressure washer, right? Not to worry. You are not alone.
This problem tends to occur very commonly and this is why I’ve come up with some easy hacks and tricks to help you get rid of this problem right away. These tips will also help you do the maintenance of the pressure washer in the future.
Remember that there can be many causes of this problem. I will start by citing the solution that is most commonly prescribed by expert engineers. Then, I’ll get into the peripheral details.
So, why wait any longer? Let’s dive right into it!!
The Main Reason Why Your Homelite Pressure Washer Has No Pressure
Simply put, pump failure is the most common cause for the pressure washer not retaining pressure. Most of the time, finding a remedy to this problem is the final solution.
If you are using the pressure washer for quite a few years and you have used it daily in its entire lifetime, it might be time to change or replace the pump. Damage in the pump or in the pump assembly is a vital problem that must be remedied to run the pressure washer well again.
How To Replace/ Install A New Pump In The Pressure Washer?
We’ll carefully follow the below 10 steps in order to replace or install a new pump into the pressure washer. When following the installation steps, utmost safety precautions are recommended. So, here we go.
- Step 1: Before attempting to change the pump, make sure the machine is cool and has not been used for the last 2 hours.
- Step 2: Remove the wire and detach the wire in the boot to the spark plug. Also, don’t forget to disconnect the hose from the pump inlet.
- Step 3: Detach the high-pressure hose too. In addition to that, use a locking plier to crimp and block the detergent solution tube. Then, you can detach the tube from the chemical injector
- Step 4: Now, remove all the nuts and bolts that are holding the engine and pump with the mounting plate.
- Step 5: Then, it’s time to remove the damaged pump. The pump should come out very easily without any force applied.
- Step 6: Now, Unpack and prepare a new pump to install. And, transfer the thermal release valve from the old pump to the new pump. Prior to installing the thermal valve to the new pump, use some sealants in the threads of the thermal valve, so it stays attached very firmly.
- Step 7: Check and confirm that the drive key is indeed in place (on the crankshaft). Now, align the notch in the pump with the key. Then, carefully slide the pump onto the crankshaft.
- Step 8: Rotate and align the bolt holes. And, reinsert all the bolts and nuts. Thread the nuts to their former position. Once all the nuts are threaded into their place, torque them into a tight position according to the manufacturer’s recommendation.
- Step 9: After the above processes are done, now it’s time to remove that cap from the new pump’s outlet. Now, connect the high-pressure hose to the outlet of the new pump.
- Step 10: Reattach the detergent solution tube to the chemical injector. Also, remove the locking plier. At last, reattach the wire in the boot to the spark plug.
After finishing all the steps above, you can check if the pressure washer is working correctly now or not. It should be working fine now.
Other Minor Reasons Why Your Homelite Pressure Washer Might Have No Pressure
Sometimes, the pump itself is not the cause of the problem. Low pressure can occur due to malfunction in the component parts too.
So, we recommend checking the below machine parts to ensure which one is causing the trouble. Let’s take a look and find out which one might be the criminal:
1. The nozzle: One of the most common causes of the pressure washer losing pressure or having no pressure is the nozzle being broken. Over many years of use, It is pretty normal to see the nozzle of the pressure washer getting damaged.
If you see your nozzle is not 100% okay, consider replacing the nozzle to solve the problem.
2. Slippery belt: The pressure being zero or low can be the cause of a slippery belt. If your belt is suffering from slippage, try tightening it or in some cases, it is better to replace it. If you replace it, make sure you choose the right size belt.
3. Air leakage in inlet: If there is air leakage in the inner construction of the plumbing system, that might be the cause of low or no pressure in your pressure washer.
The solution to this problem is simple and complex at the same time. You need to disassemble the whole plumbing system and find the leakage. Then, you need to change the machine part that has the leakage.
4. Damage in the relief valve: It is pretty normal to see the relief valve get jammed every once in a while. Also, It can even be partially plugged or the valve seat can be damaged too. The common solution to this problem is to clean and readjust the relief valve.
If the damage in your relief valve is permanent and cannot be repaired, you have to change the whole relief valve.
5. Lack of Fluid filtration: If your liquid is lacking enough filtration and at the same time, the filter of the pressure washer is worn out over the years of use, it could be the reason for the low pressure. In order to combat this problem, we recommend replacing the filter.
6. Damage in the inlet discharge valve: Dirty or damaged inlet discharge valve causes the pressure washer to malfunction by causing trouble in the fluid flow. If your machine’s parts are not clean enough, it’s ridiculous to think you can clean something else with it, right? So, attempt to clean the inlet discharge valve immediately.
7. Restriction in Airway: The air entering your pump is the same air that will bump out the water with high pressure. Which, in turn, will do the cleaning for you.
If the air entering the pump is blocked somehow, the pump will not be able to provide ample pressure on the output water. So, if you detect any blockage in the airway of the pump, get rid of it.
