Say goodbye to power loss headaches as we break down the causes and provide easy-to-follow remedies for a smooth and efficient pressure washing experience.
If your pressure washer bogs down when the trigger is pulled, there are a few things you can do to troubleshoot the issue:
- Check the intake filter to see if it is clogged. Suppose it is clean or replaced.
- Check the pump pressure relief valve to see if it is stuck open. If it is, close it and try again.

Pressure washer bogs down when the trigger is pulled - causes & solutions
If your pressure washer bogs down when you pull the trigger, it's a frustrating problem that can cause your cleaning project to grind to a halt. Fortunately, there are a few things you can check to troubleshoot the issue and get your pressure washer back up and running.
Here I'll look at eight possible causes of why your pressure washer bogs down when you pull the trigger and provide some solutions for each.
1. Blocked or Restricted Fuel Line
One of the most common reasons why a pressure washer bogs down is because the fuel line is either blocked or restricted. Over time, debris can build up in the fuel line and cause a blockage. This can restrict fuel flow and cause the engine to bog down.
You'll need to clean out the fuel line to fix this problem. Start by disconnecting the fuel line from the carburetor and using a small brush to remove any debris blocking the line. Once the line is clear, reconnect it and try starting the pressure washer again.
2. Dirty or Clogged Air Filter
Another common reason for a pressure washer to bog down is a dirty or clogged air filter. The air filter helps to keep dirt and debris out of the engine, but over time it can become clogged with dirt and debris itself. This can restrict airflow and cause the engine to bog down.
You'll need to clean or replace the air filter to fix this problem. Start by removing the air filter from the pressure washer and then use a small brush to remove any dirt and debris clogging it. If the air filter is filthy, you may need to replace it. Once the air filter is clean or replaced, start the pressure washer again.
3. Dirty Spark Plug
A dirty spark plug can also cause a pressure washer to bog down. The spark plug helps ignite the fuel in the engine, but over time it can become coated with carbon deposits and other materials. This can prevent the spark plug from firing properly and cause the engine to bog down.
You'll need to clean or replace the spark plug to fix this problem. Start by removing the spark plug from the pressure washer and then use a small brush to remove any deposits. If the spark plug is excessively dirty, you may need to replace it. Once the spark plug is cleaned or replaced, start the pressure washer again.
4. Water in the Fuel
If there is water in the fuel, it can cause the engine to bog down. In addition, water can enter the fuel tank if it isn't properly sealed or if condensation has formed inside the tank. When this happens, the water can mix with the fuel and cause problems.
To fix this problem, you'll need to drain the fuel tank and refill it with fresh fuel. Be sure to use fresh fuel that is specifically designed for pressure washers. Once the tank is full, try starting the pressure washer again.
5. Old or stale fuel
If the fuel is old or has gone wrong, it can cause the engine to bog down. Over time, fuel can degrade and become less effective. This can cause starting and performance problems for the engine.
To fix this problem, you'll need to drain the fuel tank and refill it with fresh fuel. Be sure to use fresh fuel that is specifically designed for pressure washers. Once the tank is full, try starting the pressure washer again.
6. Low oil level
If the oil level in the engine is low, it can cause the engine to bog down. The oil helps lubricate and cool the engine, but if it gets too low, it can overheat and suffer performance problems.
To fix this problem, you'll need to check the oil level and add more if necessary. Be sure to use the correct type of oil for your pressure washer. Once the oil level is correct, try starting the pressure washer again.
7. Faulty carburetor
If the carburetor is faulty, it can cause the engine to bog down. This is because the carburetor mixes air and fuel before it enters the engine. So if the carburetor isn't working properly, it can cause a lean mixture, leading to engine performance problems.
To fix this problem, you'll need to have the carburetor repaired or replaced. Again, this is a job best left to a professional. Once the carburetor is repaired or replaced, start the pressure washer again.
8. Clogged fuel filter
If the fuel filter is clogged, it can cause the engine to bog down. The fuel filter helps to keep dirt and debris out of the fuel system, but over time it can become clogged with dirt and debris itself. This can restrict fuel flow and cause the engine to bog down.
You'll need to clean or replace the fuel filter to fix this problem. Start by removing the fuel filter from the pressure washer and then use a small brush to remove any dirt and debris clogging it. If the fuel filter is filthy, you may need to replace it. Once the fuel filter is cleaned or replaced, start the pressure washer again.
The solutions to these eight common causes of pressure washer bogging down are relatively simple. In most cases, they can be resolved with some basic troubleshooting.
Tips for preventing pressure washer bogs down when the trigger is pulled
When using a pressure washer, it is essential to avoid bogging down the machine. This can happen when the trigger is pulled too hard or too long.
Here are some tips to prevent this from happening:
- Make sure the pressure washer is properly primed before use. This means adding the correct amount of water to the pump, so it doesn't run dry.
- Avoid using a pressure washer with an unloader valve stuck in the "on" position. This will cause the pump to work harder and lead to a bogging down of the machine.
- Be sure to use the correct pressure washer nozzle for the job at hand. If a nozzle with too high of a pressure rating is used, it can cause the machine to bog down.
- Make sure the cleaned area is free of debris that could clog up the pressure washer's pump. This includes things like stones, leaves, and sticks.
- Use a detergent designed for pressure washers to help loosen any tough dirt or grime clinging to the cleaned surface. This will make it easier for the pressure washer to do its job and will reduce the likelihood of bogging down.
- If the pressure washer bogs down, turn it off immediately and consult the owner's manual for troubleshooting tips. Do not try to force the machine to keep running, as this could damage it.
Following these tips can help prevent your pressure washer from bogging down when you pull the trigger. This will make it easier to get the job done and will help prolong the life of your machine.
