If you have trouble venting a pressure washer burner, follow these steps. Disconnect the fuel pump from the burner housing. Check the fuel pump bleeder. Next, check the air vents. If necessary, adjust them. Afterward, reconnect the fuel pump. You can check the other parts of the pressure washer to see if they are plugged. If the fuel pump bleeder is open, the air vents may be plugged.
Disconnect the fuel pump from the burner housing
When the fuel pump is not turning, you should try to disengage the motor. Check the fuel gauge to determine if the problem is the pump or the motor. If the motor is turning, you can simply replace the fuel pump. If it is not, you need to check the fuel solenoid. Usually, it is a green electrical coil that runs through the burner housing. To check the solenoid’s function, test the fuel solenoid with a DC volt meter or a 12 volt test light. If the solenoid does not trigger, you must remove the solenoid block and replace the solenoid.
In a 12-volt system, a low incoming voltage can cause the ignitor to malfunction. To test the spark, connect the ignitor wire to the transformer’s power source. Fold the ignitor open by about 1/4 inch and touch the tip of the blade to one of the terminals. Now, increase the distance to 3/4″ and watch for a spark jumping. If it doesn’t jump, check the other terminal. If it does, your burner is not working properly.
When you disconnect the fuel pump from the pressure washer burner housing, you can also disassemble the pressure washer’s electrical wiring. The wiring is usually labeled, and the fuel pump and burner are separate circuits. In general, pressure switches are wired so that the pressure is normally open. Disconnecting these wires should prevent the burner from starting. You can also use small pieces of tape to label the wires leading to the burner.
If you intend to fix your pressure washer yourself, a Crescent 170-piece mechanics tool kit will give you the tools you need. This kit contains everything you need to diagnose and fix common problems with power washers. The manual contains 15 different reasons why your pressure washer isn’t working and 15 fixes to fix them. It will be the most useful tool for you to use if you want to do this yourself.
Check the fuel pump bleeder
Before venting the fuel pump of your pressure washer, you need to check the bleeder valve. There are several parts to your fuel pump. Check the bleeder valve to make sure that it is not plugged. If it is, you will have to change the fuel filter. It may also be clogged or obstructed. Clean these parts and replace them. Check the fuel line and filter for any leaks or cracks.
If the fuel stream is distorted or has a large amount of air bubbles, there may be a problem with the fuel pump. The nozzle may have an obstruction or be too large for the system. If the fuel nozzle is too big, it will cause the fuel vapors to smoke and not ignite properly. The fuel pump bleeder valve is located on the side of the fuel pump.
To check the fuel pump bleeder, first remove the cover from the fuel pump. Remove the nut and strainer and clean it with fuel oil or kerosene. After cleaning the strainer, reinstall the brass tube and tighten the fuel solenoid outlet. Check the fuel pump strainer regularly. Make sure to replace it when necessary. You can purchase a replacement strainer online or at the nearest hardware store.
If you’re venting a gas-fueled pressure washer, you may want to make sure the fuel pump bleeder works properly. If you’ve recently bought a pressure washer, you may want to consider purchasing a second one, as some oil burners don’t have bleeders. These pumps are easy to find and fit in most pressure washer burner brands. If the fuel pump bleeder doesn’t work, you can try the steps again.
Check the air vents
To check the air vents on a pressure washer, start the machine and turn on the engine. Check the pressure gauge for an approximate 125 psi. Look for air bubbles in the filter bowl. This may be an indication that a leak has occurred. If the air vents are clogged, contact the fire department or other emergency services. Get yourself and your family to safety and learn what to do.
If the fuel stream is not steady, the problem may be the fuel switch. To test the fuel gauge, disconnect the fuel line from the pressure washer burner housing. Place the fuel solenoid outlet in a small container, such as a coffee can. If the fuel line doesn’t fire, it’s likely the flow switch is faulty. Replace the flow or pressure switch. In either case, the fuel vents are the source of the problem.
Adjust the air vents
One of the first things you should do if you’re experiencing problems with your pressure washer’s burner is to check the fuel gauge. Sometimes the fuel gauge doesn’t work and you have to check it visually with a dipstick. To check the fuel level in your pressure washer, disconnect the fuel line from the burner housing and move it to a holding container. Next, tighten the fitting of the fuel solenoid. A small coffee can works well for this. Then, start the pressure washer, turning on the burner.
Check the thermostat
If you have a pressure washer with a built-in burner, it’s a good idea to check the thermostat. This device is located in the electrical circuit with the fuel solenoid. The thermostat helps regulate the temperature of the water, allowing it to be supplied to the burner nozzle. The thermostat works by using a sensing device to determine the temperature of the water. Once the water is hot enough, the switch opens. This will stop the flow of electricity to the fuel solenoid valve, thereby shutting down the pressure washer burner.
Next, check the fuel cut solenoid. This sensor is located on the left side of the fuel pump. The wire should run through a metal corrugated conduit. The wire should have a green connector. If it doesn’t, replace the solenoid block with a new one. You can check the fuel cut solenoid with a DC volt meter or a 12 volt test light. If the problem persists, call a technician.
In addition to checking the pressure switch, check the flow switch. Sometimes a faulty switch can cause the pressure washer to run without heat. A bypass switch is a good way to determine whether the pressure switch is the culprit. Using a small screwdriver, insert it into the switch’s plunger. If the plunger moves but doesn’t depress the micro switch, the problem lies in the reed switch. Replace it if the pressure switch is malfunctioning.
Once you have inspected the pressure washer’s electrical components, you can check the thermostat. If the thermostat is off, the pressure washer won’t fire and a secondary circuit failure will prevent the burner from igniting. The pressure switch for the burner is wired to open normally. However, if the wires are broken, then a secondary circuit failure will prevent the burner from turning on and will not ignite.
