Customer Questions and Answers for Sequence Switch by Ge

Hi Siming. Did you totally remove the drain hose and verify it is clear ? Is the check valve flap inside the pump output in good shape so the pump does not cavitate ? It is part # WD01X10175. It also helps to insure that there is no back up of sink water. You need to verify that there is a loop under the sink clamped tight as high as possible then taught to the sink drain or disposal. This will create a p-trap effect as no sink water or drain waste smell back up in the unit. Make sure the sink or disp. connection is clear to drain into it. Follow the installation instructions supplied with the use and care guide. The pump is part # WD19X10015. Look inside the pump and check the impeller to see if it is damaged or loose spinning on the shaft. Thank You.
