Troubleshooting E3 error on Traditional FlexFit: Step 2

The first step in troubleshooting an E3 error is determining if you own a Sleep Number Traditional FlexFit base or a Sleep Number 360 Smart FlexFit adjustable base.

This article will help you troubleshoot this error on a Traditional FlexFit adjustable base.

1. Check power connections

Make sure that:

  • You are in the same room as your bed when you use your remote.
  • The main power cord is plugged into a grounded outlet that is not controlled by a switch.  
  • The detachable end of the power cord is firmly connected to the pump.
  • The red power switch is illuminated red when on
  • Try taking the batteries out of the remote and putting them back in to clear a frozen remote.

2. If you still are experiencing an E3 error after checking power connections, we recommend the following:

  • If your bed is plugged into a surge protector we recommend plugging your FlexFit™ adjustable base into a wall outlet or power strip instead. The base may not be getting enough power or you may have a faulty surge protector or power strip.
  • Try power cycling your FlexFit™ adjustable base by unplugging and plugging it back in.  This forces the control system to switch to a different remote channel.
  • Sometimes a remote channel gets busy.  Your base has four radio frequency channels. You can try power cycling up to four times or any time you notice a recurrence of frequent E3 errors.
  • Have you recently installed a replacement FlexFit control system?  Complete a factory reset on your remote to pair your remote to your bed.
