Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank´s for your help, I already recived these manual from you

Caring for Your Dishwasher
Cleaning the exterior
In most cases, regular use of a soft, damp cloth or sponge and a mild detergent is all that is necessary to keep the outside of your dishwasher nice looking and clean.
Cleaning the interior
Hard water minerals may cause a white film to build up on the inside surfaces, especially just beneath the door area. To clean interior: � Apply powdered dishwasher detergent to a damp sponge to make a paste. OR � Use liquid automatic dishwasher detergent and clean with damp sponge. Do not clean the dishwasher interior until it has cooled. Wear rubber gloves. Do not use any type of cleanser other than dishwasher detergent because it can cause foaming or sudsing. NOTE: See �Removing spots and film� in the �Solving Common Dishwashing Problems� section to clean your dishwasher with white vinegar. Remember, this procedure is intended for occasional use only. Vinegar is an acid. Excessive use can damage your dishwasher.
Overfill protector
The overfill protector (in the front right corner of the dishwasher tub) keeps the dishwasher from overfilling. It must be in place for the dishwasher to operate. Check under the float for objects that may keep the protector from moving up or down.
