came in this morning turned on my roland vp 540 and I am getting the error message service call 109. I know this is a wiper error, I tried manually moving the wiper, still getting error message. I am guessing it is the sensor, is there a diagram anywhere to show where the sensor is? Is it possible it needs to be cleaned?
