Types Of Portable Pressure Washers

Before deciding on which pressure washer you will stick to, you have to first understand the different types of portable pressure washers. The standard way of differentiating these machines can be through their functional capacity and power source.

According To The Source Of Power

  1. Electric engine – just as the name implies, these engines are connected to an electric power source and are mostly used for light to moderate home use. Apart from being plugged into an electric socket, they can also be connected to a power generator.
  2. Petrol or gas engine – mostly useful in industrial and commercial applications, these Petrol or gas pressure washers use to perform medium to heavy tasks.
  3. Diesel engines – these are related to petrol engines, only that they use diesel instead. They work more or less like gas engines and should only be used outdoors due to the fumes they emit.
  4. Hydraulic engine – equipment that utilizes hydraulic pressure is mostly found in an agricultural setting. They are quieter, less heavy, and are very compact.

According To Functional Capacity

The functional capacity of pressure washers is divided into 4 main parts of:

  1. Light duty – these have a pressure rating of between 1300 to 2000 PSI. They are made to deliver a maximum of 2 GPM. Light duty pressure washers are best used in accomplishing domestic cleaning purposes such as garden equipment, patios, motorbikes, and even small cars.
  2. Medium duty – with a pressure rating of between 2000 to 2800 PSI, these washers deliver a flow rate of about 2 to 3 Gallons per Minute. Best for cleaning bigger cars, large patios, swimming pools, etc.
  3. Heavy-duty – heavy-duty pressure washers have a pressure rating of between 2900 to 3000 PSI. The flow rate of 3 to 4 GPM makes them very ideal to perform heavy-duty tasks such as cleaning large trucks, stone, and brickworks, etc.
  4. Extra heavy-duty – these machines are extra powerful and are used to perform heavy tasks. They have pressure ratings of above 3000 PSI.

How To Choose The Right Portable Pressure Washer

After understanding the different types of portable pressure washers available in the market, it is paramount to now choose the right one. Since there are many options to pick from, here are the top 3 considerations before choosing a portable washer water tank.

1) Purpose

What are you planning to use the pressure washer for? Will it serve the intended purpose well? For domestic cleaning purposes, a light duty washer will be enough for you.

If planning for commercial use or washing large vehicles, you will need a medium-duty washer. A heavy-duty washer will be perfect if you will be using it to clean large equipment, industrial use, etc.

2) Location

Your location or the location from which the product will be used also greatly matters. A light-duty power washer will be inefficient if you intend to use it in a barn or large industry.

Moreover, if you have very sensitive neighbors and do not want to experience regular complaints from them, choose an electric-powered light washer. This is because it produces very minimal noise and exhaust fumes.

3) The source of water

Where you will be getting the water greatly matters. It is imperative when you get water directly from the tank to get a filter that will help prevent the entry of debris. Not considering this factor can bring forth unforeseen damages to your pressure washer.

Factor To Consider When Buying a Pressure Washer

Apart from the above considerations, you have to also consider a number of features which the product you intend to buy has. Doing so will help you avoid disappointments later on while using the product.


How easy is the washer to move from one location to another? Will you get very exhausted at the end of performing heavy tasks?

Power ratings

Some portable pressure washers use two methods to rate their power output, while others use three units of measure. The most common units of measurement include Gallons per Minute (GPM) and Pounds per Square Inch (PSI).

The third measurement stats which help you to further identify the ideal pressure washer is Cleaning Units (CU). The CU is easy to calculate as you just multiply the PSI by the GPM.


Ensure to read the fine print before purchasing any pressure washers. Find out what the warranty covers (if any) and compare it with others. It is recommended when the warranty can cover both the engine and the pump.

Hot and cold water pressure washers

Some pressure washers are built to withstand and utilize hot water. While hot water is very efficient as it easily removes dirt using the smallest amount of detergent, cold water pressure washers cannot sustain it. The hot water in cold water only pressure washers might damage the coils or the entire washer system.

Wands and nozzle tips

The nozzle tips are different and can range anywhere between a 0-degree point jet to 65-degree wide spray.

Pressure Washer Troubleshooting

No matter how careful and thorough you are when choosing your pressure washer surface cleaner, it will experience some problems at one point in its life.

The issues could be easy to diagnose, like fixing leaking water, or more challenging to diagnose, requiring you to tear down the pump. Nevertheless, you should not be quick to return the washer the moment it experiences a problem.

Learning how to diagnose and even repair your pressure washer could prolong its life and ensure quick, efficient cleaning every time you clean your home. Even the best home power washer will suffer from tear and wear or clogging.

Luckily, some of the common pressure washer problems do not require you to take it to an expert for repairs. You can quickly and efficiently rectify the issues without a sweat.

Our goal is to help you squeeze more life out of your power washer before you can start looking for power washing services near me with simple to use DIY troubleshooting tips and tricks. You will find these troubleshooting guides useful for gas and electric pressure washers.

However, it is helpful to check the manufacturer’s manual for safety and troubleshooting tips first. You also need to be aware of the problems that have more possible solutions for you to try. The pressure washer troubleshooting problems that we will help you fix in this guide include:

  • Water pressure problems
  • Engine not starting or working properly
  • Water leaks
  • Injector not working
  • Noise
  • Oil leaks

How to Repair a Pressure Washer

1) Water Pressure Problems

No pressure

The right diagnostic solutions depend on the cause of the problem. Your pressure washer may not have strength if it has damaged unloader valve or damaged pump inlet valves. You may need to open the machine to troubleshoot and fix the problem.

  • Damaged unloader valve: Open the unloader screw and look for broken springs and seals. Replace them as necessary.
  • Damaged pump inlet valves: Disassemble the unit and look for dirty or broken components. Clean the dirt and replace the worn-out valves of the inlet manifold.

Low Pressure

Some of the issues that cause low pressure do not mean that your washer has a problem. It could be a wrong application or even a blocked garden hose. You need to check for insufficient inlet water supply, use of the wrong nozzle, or blocked water filter.

  • Water supply not sufficient: Look for twisted hose and ensure you have full water pressure from the tap. Using the wrong sized garden hose could also cause low pressure. Check the manufacturer recommendations to ensure you have the correct diameter sized garden hose.
  • Blocked filter: Check the inlet water filter for blockage if the water supply from the source is right. Dirt and debris can reduce water pressure. Remove the hose connection and clean the debris.
  • Wrong nozzle: Not using a nozzle or having a wrong nozzle can affect the pressure. Refer to the manufacturer guide to ensure you have the right nozzle and change it accordingly.

Pulsing pressure

The problem of pulsing pressure involving high and then is highly prevalent. The rhythmic water pressure can occur due to several factors ranging from a faulty pump to the damaged manifold, water obstruction, and air sucking.

  • Pump sucking air: Air sucking is the primary cause of pulsing pressure. Before you can start worrying, turn off the washer and keep the water supply running. Squeeze the trigger gun to release the tension and then start the pressure washer.
  • Obstruction: Dirt can obstruct the water inlet and nozzle to create pulsing pressure. Deposits in the wand or gun may also be the cause of the problem. You can use fresh water to flush inlet filter, needle to unclog nozzle, and vinegar to clean deposits from the wand.
  • Faulty or damaged components: Fix the problem by disassembling the pump. Check for broken or dirty valves and replace or clean them. If that does not solve the problem, you may need to replace the pump.

Unsteady pressure

Unplanned pressure spikes or drops can make cleaning your home or car problematic. Pressure spike is dangerous as it can damage your surface while pressure drop increases the cleaning duration. You can use these remedies to fix pressure spike or drop.

  • Spikes: A poorly calibrated unloader valve is the primary cause of pressure spikes. Refer to the manual to adjust the unloader to the correct pressure.
  • Drops: Several issues could make the pressure drop after cleaning for some time, including unloader valve problems and nozzle blockage. It is easy to unblock the nozzle with a needle to ensure steady pressure. A dirty or faulty unloader valve can also make the pressure drop. Thankfully, you only need to remove the unloader for cleaning or repairs to restore your pressure washer functionality.

2) Water Leak Problems

Leaking pump

Before you start fixing a pump, you may need to look at your warranty cover. Disassembling the pump can void the warranty, but there are things you can do to stop leaks without voiding it. Water leaks from the pump can occur due to various issues like broken seals, loose bolts, and an activated thermal valve.

  • Broken seals: Check whether your washer warranty is active and return it for replacement.
  • Loose pump bolts: Loose bolts will create a gap on the pump casing. Fix the problem by tightening bolts to ensure proper sealing.
  • Activated thermal valve: Wait for about five minutes before using the pressure washer again. The valve will de-activate immediately it is cool enough.

Hose connection leak

A broken or improper connection of the garden hose can cause leaks. Disconnect the hose and reconnect properly. You may need to check the rubber washer to ensure it is not broken. A broken rubber washer will require replacement as it can allow the water to leak.

Spray wand and connections leaks

If you notice leaks on the wand, you should check the connections. Improperly connections will not be tight enough to prevent leaks. You may also check the o-ring inside the hose connection to ensure it is not broken. Replace the broken o-ring and connect properly.

3) Gas Powered Washer Engine and Power Issues

The engine does not start

You may experience trouble starting a gas powered washer engine if it does not have gas or the choke is in the wrong position. Make sure the washer has gas, and the choke is in the correct position as per instructions before trying again. Other problematic issues include pressure build-up, spark wire disconnection, or faulty spark plug. Release the pressure in the system by squeezing the trigger gun. Check the spark plug connection and make the right connection or replace the plug if faulty.

Not enough power

If the engine is running but not producing adequate power, you need to check the following.

  • RPM: The engine will not provide enough power if it is running at the wrong RPM. Detach the pump and adjust RPM to the recommended engine specifications.
  • Dirty air filter: Check the air filter for dirt and clean or replace it accordingly.

Engine stops while in use

Confirm the oil level and refill as necessary. Dirty filters can also make the engine stop while it is in use. Clean and replace the air filter regularly to improve efficiency.

Water in oil

A pressure washer could have water in oil if the pistons are broken or worn. It may also occur if seals are worn. The warranty usually covers pistons and seals problems. Talk to your manufacturer to get the problem fixed.

4) Electric Powered Washer

The washer will not start

The best home power washer will not start if the electric outlet is not plugged in or faulty. Check the plug and main fuse to ensure the problem is not the power source. The pressure washer will further not start with a defective motor. A defective motor will need replacement, which can be under warranty.

5) Other Issues

Injector not working

Most problems with the detergent or chemical injector are as a result of using the wrong nozzle. Check to ensure the black soaping nozzle is on the wand. A clogged inlet filter or valve will lead to problems with the injector. A clogged inlet filter is easy to clean with fresh water. However, you will need to remove the hose to unblock the soap inlet valve.

Loud noise

Your water pressure will produce more sound if the water intake is blocked, which you can quickly fix by cleaning the intake. Inadequate oil in a pump or engine can make your machine noisier. It is necessary to regularly check and add oil to increase the lifespan of your washer.

Final Word

Your tedious search for the best portable pressure washer with a built-in water tank will finally come to an end thanks to our comprehensive list. Take note of the buyers’ guide and you will never have to face disappointments after purchasing poor quality pressure washers.
