    PDQ M5 unit, Access unit says enter wash, but wash does on turn on.

    If always happens with a certain wash package, bad cable or bad relay. If issue shows up with any package, could be a bad proximity sensor or sensor that triggers the back up is blocked (dirty), so the CPU does not activates the wash because is reading that there is still a car in there.

    Mark VII Aquajet XT PMP-K20-F086:Fuse Tripped Error

    First, I would test the cable to the motor with a Megger and visually check wiring in the electronic cabinet (mice love german wiring). If you are pretty sure that happens only when switching from presoak to HP rinse, check the low pressure pump for moisture inside the junction box, grease the...

    Best New Touchless System

    I agree that not all brands are the same and will mostly depend of your distributor/servicer efficiency. If you have a long bay, there is not need to restrict it to a touch-less only. A Mark VII choice wash could be a good option (once Mark VII figure out why their heater tank keeps tripping)...

    Trouble shooting help: EMV reader "offline"

    I believe you can call DRB for tech support as a owner, there is a serial number inside the unit on the wall that you have to give it to them. If there are LEDs ON on the front, probably you have to check if you have internet to the router or swith inside the unit, also make sure your printer...

    Ideas? Titration Problem nightmare

    Looks like you are working on a GT300 or GT500?. I would ran your presoak line directly to the side manifold only (no Y for the hubscrub). Purge the presoak with the chemical line disconnected on the T that mixes with water, leave the check valve connected on the T, and make sure that check...

    Reliability of Mark VII ChoiceWash XT

    I have been a carwash tech for the last 10yrs, mostly serviced Mark VII, but also some PDQs and Ryko. You guys are pretty much correct about the confusion that generates on customers who prefer a touchfree a ChoiceWash with brushes. But, also I have noticed that it depends of the type of...

    Telemecanique Prox Cables

    For the Telemecanique like XS618B1NAM12 (treadle sensors) you can use the 6YB38 or E18018, Grainger sells those ones, but probably you'll get them cheaper on Ebay.
