For homeowners and businesses alike, pressure washers are indispensable tools, especially when it comes to outdoor cleaning. But what happens when this powerful cleaning assistant starts misbehaving? Knowing how to troubleshoot pressure washer problems can save you from frustration and unnecessary costs.

In this blog, we’ll cover some of the common pressure washer issues and provide you with practical solutions.

Problem 1: Pressure Washer Won’t Start

This is perhaps the most common issue. If your pressure washer refuses to start, consider these possibilities:

1. Check the fuel: Your pressure washer might be out of fuel, or the fuel might be stale if it’s been sitting in the tank for a long time. Top up the tank with fresh fuel and try again.
2. Check the spark plug: A dirty or faulty spark plug can prevent the pressure washer from starting. Cleaning or replacing the spark plug often resolves the issue.

Problem 2: Pressure Washer Has Low Pressure

If your pressure washer isn’t providing the strong spray you’re used to, here are a few potential causes:

1. Check the nozzle: A clogged or incorrect size nozzle can reduce pressure. Clean the nozzle or replace it if necessary.
2. Check the water supply: A low or inconsistent water supply can lead to decreased pressure. Ensure your water source is providing enough water at a steady rate.

Problem 3: Pressure Washer is Leaking Water

Water leaks can occur for various reasons:

1. Damaged seals: Over time, seals can wear out or get damaged, leading to leaks. You’ll likely need to replace these.
2. Loose connections: Check to ensure all hoses and connections are securely fitted.

Problem 4: Pressure Washer Pump is Making Noises

Unusual noises from the pump might be due to:

1. Cavitation: This is caused by insufficient water supply or a blockage in the system, causing the pump to pull in air.
2. Worn out parts: Bearings or other internal components could be worn out, leading to noisy operation. Consider getting a professional to examine the pump.

Problem 5: Pressure Washer is Producing Smoke or Smells

If your pressure washer is producing smoke or strange smells:

1. Check the oil level: Running the pressure washer with a low oil level can cause overheating and result in smoke or burnt smells.
2. Investigate for leaks: Oil or fuel leaks might cause smoking or odors when the machine is running.

Remember, if you’re ever uncertain or uncomfortable with DIY troubleshooting, don’t hesitate to call a professional. Regular maintenance and correct usage also go a long way in preventing pressure washer problems.
