A pressure washer is one handy tool you can use to create high-level pressure cleaning all-around your property. You can use it to clean your home, your swimming pool, and also your car. It’s also ideal for dealing with weeds around the home or fence cleaning. However, all these are feasible if the pressure washer works correctly, including the pressure washer pump.
Since it’s a piece of the machine with multiple moving parts and prone to wear and tear, you will face some problems here and there while using it. Some issues are quite common than you may think. This post is here to give you an insight into the various problems you’ll face while using a pressure washer and how to fix a pressure washer pump if you experience any related to it. Read along!
Common Pressure Washer Pump Problems and How to Fix Them
Most of the time, the one piece that fails most is the pressure washer pump. Of course, this is the same part that might make your worries over the bar when there is an issue with your pressure washer. And thanks to this piece, you will not face the same problems with fears and worries.
But first, before anything else, safety first. You need to make sure the pressure washer is switched off and disconnected from the power socket before starting. If you’re using a fuel pressure washer, you’ve to take out the spark plug wire.
The most common problem experienced with a pressure washer pump is pressure leaks. These leaks are more likely caused by worn out, faulty, or damaged components. The most vulnerable parts include;
If the leak is coming from the pressure washer hose, that will not make you panic. The problem of a leaking hose is a sign of worn out or perished gasket or O-ring at the hose base. Repairing it is straightforward – replace the old perished gasket with a better, new one.
If the leak is coming from within the pressure washer case, the problem might be some leaks in the cylinder head or the inlet or outlet elbow. The cause of all these might be quite simple as trapped water is not drained correctly before winter. It this water freezes, it will expand and result in damages to the plastic and rubber parts.
#c. Identifying Leaks
If the leak is happening inside the case, it can be hard to visually identify where the cracks are, either on the cylinder head or on the inlet and outlet elbows. Troubleshooting the problem requires you to take out the front case, apply the water hose while the unit is unplugged and turn the water on. The water pressure will help you identify the specific piece of these three parts, causing the leak, and after that, you can replace it.
If the issue is caused by a faulty or a problem in the cylinder head, the pressure will pulse and trigger the pressure that stops the unit when not used to disperse quickly. That leads to the motor restarting or pulsing.
Another problem that can cause your pressure washer motor to pulse can be water starvation. If the water inlet filter is blocked, there be less to no water reaching the pressure pump. Solving the problem is relatively easy.
All you need is to remove the filter and clean it off the blockages. Do this if the unit is your machine is pulsing but not when it’s leaking.
#3) Worn Pump
A worn-out pump isn’t standard, but it can happen if you operate your machine without changing oil leading to premature wear. It can also be because you used the wrong lubricant or oil. Water could also get into the pump housing, or you might have run the machine with no water. If your pressure pump is worn out, you have to get a qualified technician or do a pump replacement.
#4) Air in the System
When there is air in the system, the pump will cause shuddering and vibrations. You may also experience low pressure or even sporadic pressure. The problem is between the machine’s water pickup and the pump itself.
When the pressure pump is on, it sucks water with air, and it creates a vacuum leading to pulsating. You need to check the hoses or the fittings; replace them if damaged or if there is a leak
Panicking is allowed when one reaches a point-blank with an unsolvable problem, but that shouldn’t be the case when a pressure washer breaks down, and the pump is the culprit. Next time you face the issues I have listed here, there is an easy way to fix it, as I have explained here.
