Troubleshooting E4 Connectivity Error

Applies to Silver 360 traditional remotes (5-, 9-, or 12-button) and 360 smart bed remotes (5-, 10-, or 12-button).

An E4 error means your remote lost connection to your Sleep Number bed or FlexFit adjustable base. In many cases, the issue is caused by a temporary power or communication problem. Even after the connection is restored, the message may stay on the remote until you remove and reinsert the batteries.

• Not sure which bed or remote you have? 360 smart beds were sold between 2018 and 2026 and usually have dark silver remotes. Traditional Sleep Number beds purchased before 2018 usually have light silver remotes. Use the remote images below to identify your model.
• Check the LEDs on your pump. The 3rd light on the pump shows connectivity status.
  • If the 3rd LED is blinking or solid, the connection has been restored. Remove and reinsert the remote batteries to clear the error.
  • If the 3rd LED is off, there is still a connectivity problem.
• Before you begin: Stay within 15 feet of the bed. Make sure the bed is plugged into a working outlet that is not controlled by a wall switch. If needed, test the outlet with a lamp or phone charger.

Common Causes of an E4 Connectivity Error

• Temporary loss of power to the control system or pump.
• A loose power cord or wire connection.
• Low or weak batteries in the remote.
• A temporary communication issue between the remote and the base.

What You Need Before You Start

• Your remote.
• Access to the power cord, pump, control box, or base unit, depending on your model, and the wall outlet.
• Fresh batteries for the remote, if available.
• Space to safely reach under or around the bed.
• A second person if the bed needs to be moved.
• If you cannot safely get under the bed, skip to the support section for live help or in-home service options.

How to Fix E4 on a Sleep Number 360 Smart Bed

Step-by-Step Troubleshooting

1. Check the power connections at the head of the bed and at the pump.
   • The pump lights should be on when the bed is receiving power.
2. Power cycle the bed by unplugging it for 30 seconds, then plugging it back in.
3. Remove the batteries from the remote, then put them back in.
   • This clears a frozen remote and prompts it to reconnect to the bed.

4. If the remote shows a low battery icon or will not turn on, replace the batteries with fresh ones.

   Access tip: If it is hard to reach under the bed, raise the base if your model allows it, move bedding out of the way, or ask another person to help. If you cannot safely access the connections, contact support for next steps.
