Ohm Test
1. Disconnect the bin switch wires to isolate the bin
switch from the control board.
2. Connect an ohmmeter to the disconnected bin switch
wires.
3. Cycle the bin switch open and closed numerous times
by opening and closing the water curtain.
NOTE: To prevent mis-diagnosis:
• Always use the water curtain magnet to cycle the
switch (a larger or smaller magnet will affect switch
operation).
• Watch for consistent readings when the bin switch is
cycled open and closed (bin switch failure could be
erratic).
