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

Cleaning the filter
The water drain filter
A clean filter is important for the correct functioning of the machine, and should therefore be cleaned after every washing programme. Open the filter door and place a container underneath to catch any spillage. If the filter is blocked and the machine is unable to drain you will need to drain the water manually from the machine at this stage. To do this, unhook the drain hose from the standpipe or sink and hold the end of the hose over a bowl on the floor. The water should drain by gravity into the bowl. When the bowl is full, hook the hose back up and empty the bowl. Repeat the procedure until water stops flowing out. Unscrew and remove the filter. Clean carefully under a fast running tap. Replace the filter turning now clockwise and tighten it.

Never remove the filter during a wash cycle, always wait until the appliance has finished the cycle, and is empty. When replacing the filter, ensure it is securely retightened so as to stop leaks and young children being able to remove it.

The water inlet filters
If your water is very hard or contains traces of lime deposit, the water inlet filters may become clogged. It is therefore a good idea to clean it from time to time. Turn off the water taps. Unscrew the water inlet hoses. Remove and clean the filters using a hard bristle brush. Replace the filters and tighten up the inlet hoses.
