Question1: I accepted to have a rocking WW2.0 now,lol. It rocks a little when it gets to the home position because the idler wheel on passenger side is few millimetre above the rail(so not touching the rail as explained above). No issues so far, we washed almost 100 cars and no error. Just one...

There is a long hose from the float valve going to almost bottom of the tank so making sure no air is introduced... but if the CV gets stock all of a sudden, then how come the rinse is ok? I do realize that the rinse is from city water but it also gets some hot water from the hot water tank...

Damn it ... it happened again... how air possibly can get in to the high pressure hose? Also shouldnt i notice some bubbles in the hot water tank if air comes back to the hp line and then back to the tank? Not sure if this is related, the ball valve and check valve under the hotwater tank which...

Update: noticed after few wash that the drive leg stops while the other leg goes. From safety point of view the machine is smart enough to bring back the passenger leg back but will ask the customer to exit without finishing all the passes. I noticed that the leg stops on the passes that I have...

Greg, I have not checked the drive wheels diameter... but perhaps they are different as the wheel are not new.

Update: Ok boys I did it... started the automatic and washed my car 2 times...no issues and had few customers already... it seems like the wheel are adapting themselves as sometimes i dont even see that 2mil lifting up the wheel....

Correct, I did change all the valves, specially one of the low pressure valves was missing o-ring. so far no issues...Rinse is cold and it has city water pressure behind it... but HP soap and wax come from hot water tank which is only gravity pressure... so I think the problem was the low...

I think I'm 99% there, I checked it this morning, and all it is only for 2feet or so the idler wheel on passenger side lift itself up abit(maybe 2-3milimiltter) so it wont contact the rail and it wont turn, but it will come back to the rail after. Am I overthinking this? Should I go ahead and...

Update: Changed the motor and still same issue. Next step: making sure railing is level, and then changing the wheels...I hate my automatic machine...

in a pump that's already working? Rinse has no issues..when we choose hp soap and wax (which comes from hot water tank), we see this issue.. so we thought there is too much turbulence in the hot water tank and air gets into the pump through that..but not sure why all of sudden we get too much...

No when the pressure drops to zero it stays... and then all of sudden it starts and goes all the way to 1200psi, as if the belt is cut for few seconds and then its back on... its either totally dead or 1200 psi, but when it comes back from 1200 psi to zero it does the pulsing...anyways since I...

thanks found it in below link, no it for sure didn't look like this ... http://www.autocareforum.com/showthread.php?10394-head-washout&highlight=washed+head

Update: Noticed the new motor I put in is not 100% the same as the faulty one. Motors on both legs need to be exactly identical. The new one is 1740 RPM while the old one is 1725 RPM. I'm thinking because of that one leg moves slightly faster, that makes the other leg's wheel to lift up. I'll...

Thanks, I did check it and noticed some residual from the o-ring so removed it. But I don't quite know what washout means. I didn't notice any grooves or something like that at the end where the valve sits when I looked with a flashlight. Also noticed the pump pressured increased by almost 100...

Update: Changed all the valves and noticed the washer on one of the low pressure valves was gone... hope this helps the problem...

Update:changed the motor and the entire machine goes back and forth like usual to some extend( pls keep reading) So the motor was the issue. When i changed the motor before connecting it to the gearbox i switched on the machine and the other motor started to bring the entire machine to the...

Hello one of my pumps started acting strange. Sometimes the pressure goes almost to zero but i see that the motor works and the belt turns so it must be turning the pistons inside the pump. But then randomly it goes back to the 1200 psi as it supposed to be at. Is my high pressure valves bad?

Just one question, what kind of an oil and how much should I use for the gear box? Because when I Opened the side of it all the oil drained. Thanks

Thanks i did take them all apart. The motor turns but doesnt seem to have enough juice to turn the gearbox. we increased the frequency at the vfd but the voltage at the motor didnt go over 50esh volt. We did take the gearbox apart and it doesnt seem to be seized. So im going to get a new motor...

well I can hear the motor working but it sounds like it doesn't engage the gearbox. But I will check the amp on it to make sure its not an electrical issue. Thanks
