Here are a few steps to follow to troubleshoot your jetter:
*Check you have a full water tank, and you have water going to the machine.
*Make sure you have fuel in the fuel tank, the fuel tap is turned on, and the fuel tank breather is open.
*Ensure the emergency stop button is in the out position to allow the Jetter to start.
*Turn the battery isolator to the on position and check to see if the hours come up on the screen when the key is turned to the on position (Honda).
*Listen to hear if an audible click is heard from the fuel solenoid when turning the key from off to on. (Honda GX690 and Vanguard 27hp and 31hp). Have the main ball valve open and an open main reel hose.
*Crank the machine over with the choke out and ¼ throttle for about 3-4 seconds.
*If it doesn’t start, don’t keep cranking, as you will drain the battery down. If the battery is flat, you can use jumper leads to start the machine.
*If the machine still doesn’t start, check for any loose or broken wires, connectors that have come apart or bullet terminals that are not together correctly. Try again.
*If it still doesn’t start, ring a service agent, and book it in for it to be looked at by a service technician.
