Why Karcher Pressure Washer Burner Not Working
Dirty Burner
The burner is not getting enough oxygen to burn properly. This can be caused by a dirty burner, a clogged air filter, or a blocked fuel line.
Blocked Fuel Line
The fuel line is blocked, preventing fuel from reaching the burner. This can be caused by a kink in the fuel line, a clogged filter, or a faulty fuel pump.
Faulty Fuel Pump
The fuel pump is not pumping fuel to the burner. This can be caused by a faulty fuel pump, a clogged fuel filter, or a loose fuel line connection.
Faulty Igniter
The igniter is not igniting the fuel. This can be caused by a faulty igniter, a loose igniter connection, or a bad spark plug.
Bad Spark Plug
The spark plug is not sparking, preventing the fuel from igniting. This can be caused by a bad spark plug, a loose spark plug connection, or a dirty spark plug.
