My machine was working yesterday and now it is not. What should I check for?

If your machine is not functioning, the first item to explore is possible mechanical/electrical problems. Check the incoming power and fusing in the panel, then ensure that the belt has not broken. Next, verify that the drive has not seized-up by trying to spin it by hand, and then inspect the motor. Once these items have been examined and eliminated, focus on the process parameters: water flow rate, media level and compound drum level. It's also important to note that the weight settings should not be changed when the machine is not working properly.
