    Not sure that's the problem. After I close the door, the pump runs for a second or two, then shuts down. All lights are of when I then open the door.

    The pump has always run first thing since the unit was new seven years ago. Is this not normal? We are on a septic system and as a result rarely use our garbage disposal ( once or twice a week). the pump usually runs for 30 seconds and then the wash cycle begins.

You could have a loose door switch.

I am assuming by 2nd or 3rd try you mean you have to open and shut the door and then press the start button.

Refer this diagram of the front panel. The door switch and lever are shown in the detail on the top left corner of the diagram. It is part 3 in the parts list.

Please post a comment to confirm if this is the helpful or not.

    Thanks for clarifying this and providing the details of diswasher state at end of each failed attempt.

    It looks like the reason the pump is running is there is water from previous cycle or some back flow from the sink drain which is causing the pump to start and expell it on your initial attempt to start.

    Might be best to check if the drain is clear. If using insinkerator make sure it is run before you start the dishwasher so that there is nothing left to block the drain water from dishwasher.

    Please post a comment to confirm if you observe anything I mentioned above.

    In between this problem was locked to another expert and I was not able to respond.

    I notice the problem is not fixed yet.

    The reason the dishwasher does not switch to wash cycle when drain pump stops is that the float switch is faulty. It is telling the dishwasher that it is already full and not taking any water in.

    The float switch is as shown in the diagram. which is under a disc like this on the base.

    Press it a few times to check if it is not stuck. Should move up and down. But if the float switch is faulty then it will to be replaced.

    ope this will fix the problem. PLease post a comment to confirm. Please rate the solution.

Selecting 3rd gear

Do you mean you can\'t find 3rd gear or it won\'t shift into 3rd gear? If you can\'t find 3rd gear, shift all the way down to neutral, then shift up 2 clicks. On my Suzuki Boulevard S-50 (VS-800) the shift order is 1st gear down, then up for neutral, 2nd, 3rd, 4th, and 5th. Your crotch rocket probably also has a 6th. If the problem is that it won\'t shift into 3rd, then you had best take it to the shop as it is not readily repairable without specialized tools and knowledge.

My chevrolet aveo won't intermittently move from 2nd to 3rd or 4th gear, and have to reduce speed and move back down to 2nd and try again ....notice it more if trying to move up the gears quickly

This transmission is electronically shifted via solenoids controlled by a computer, so you need to have that tested for fault codes that may be in memory.

I had a friend that had this problem.I work at a G.M.dealership and I ask a friend that does trans work there.He said this is normal in cold weather.This is done in order for the trans to reach operating temperature sooner.This could be why you are unable to fix this problem because it is normal.I looked in service info to see if I could find a bulletin or something to back this up but I did not find anything.I know this guy very well and I know he knows his work and is good at it.Hope this helps.Good luck.

Sounds like a bent shift fork of broken dog gear. Try cleaning the inside of trans with part light oil and solvent. (not fuel) Rock bike a few times and shift gears, Do not start.
