Water Level Control:
Make sure the float rod and float ball move freely up and down in the solution level control box. A common error is failure to remove the shipping tag and the rubber grommet prior to use. Pushing down on the rod turns on the water fill. Pulling up on the rod shuts off the incoming water. The rod must move freely up and down without binding to prevent solution overflow and spill. Be sure your water supply line is large enough. If you have low water pressure a larger supply line will be required.
Pump Rotation Direction:
Verify the proper rotation direction of the wash pump. The phasing of the power to the machine determines the rotation direction of the pump. Make sure the pump is turning in the direction of the arrow on the motor. To do this start a wash cycle and then shut it off while watching the pump shaft as it slows to a stop. Running the pump backwards will greatly reduce your cleaning results and over time, damage the pump. Reverse any two of the three incoming power lines to change the pump rotation direction.
