Troubleshooting

To troubleshoot the problem with your MI-TM pressure washer burner, you will need to first identify the cause of the problem. You can do this by following these steps:

1. Check the fuel filter. If the fuel filter is clogged, it will prevent the fuel from reaching the burner. To check the fuel filter, remove it from the pressure washer and inspect it for any debris. If the fuel filter is clogged, replace it with a new one.
2. Check the fuel pump. The fuel pump is responsible for sending fuel to the burner. If the fuel pump is not working properly, it will not be able to provide enough fuel to the burner. To check the fuel pump, turn on the pressure washer and listen for the fuel pump to run. If you do not hear the fuel pump running, or if the fuel pump is making a loud noise, the fuel pump may be faulty. You will need to replace the fuel pump.
3. Check the pressure switch. The pressure switch is responsible for turning on the burner when the pressure washer reaches a certain pressure. If the pressure switch is not working properly, it will not be able to turn on the burner. To check the pressure switch, turn on the pressure washer and watch the pressure gauge. If the pressure gauge does not increase when you turn on the pressure washer, the pressure switch may be faulty. You will need to replace the pressure switch.
4. Check the burner assembly. The burner assembly is responsible for igniting the fuel and producing the hot water. If the burner assembly is faulty, it will not be able to ignite the fuel. To check the burner assembly, remove it from the pressure washer and inspect it for any damage. If the burner assembly is damaged, you will need to replace it.
5. Check the electrical wiring. The electrical wiring is responsible for sending power to the burner. If the electrical wiring is damaged, it will not be able to provide power to the burner. To check the electrical wiring, inspect the wires for any damage. If the wires are damaged, you will need to replace them.
