What E4
actually means.
On the Searwood the display clips onto the hopper and connects through a USB-C plug at its back. E4 shows when the board and the display lose their link, which can be as simple as a plug that has been knocked half out or as serious as a failed board.

What to do when E4 shows on the grillKind of codeController and display
The controller itself reported trouble, or stopped answering: a display that flickers or shows segments missing, buttons that no longer respond after rain got behind the panel, a board whose relays stick, or an app that will not keep its connection. A full power cycle, done as the manual describes with the grill cold, clears a passing glitch; a code that returns, or any sign of water behind the display, means a board or a keypad, and that is a visit.

A grill error code shows as letters and numbers on a pellet grill controller, a flashing light on a digital control panel, or an alert in the maker's app paired with the grill.

Weber grill calls often come from a flame that dropped low mid-cook; the tech starts at the tank, the hose and the regulator.

Before you book,
in this order.
Each step comes from Weber's own guidance for E4 on its grills. Follow it to the end: the last card says whether this is a visit.
Let the grill shut down and cool fully, then unplug it.
Check that the display is seated firmly on the front of the hopper without prying it with tools.
Plug back in and start a cook so the controller can run its 30-second check.
If E4 stays, book a visit to check the display cable and the circuit board.

It usually turns into grill lights and electronics repair. Book with the code and the model number.
What not to do
E4 is not a Wi-Fi or Bluetooth problem with the Weber Connect app; an app that will not pair shows no E-code on the grill. It is also not the Grill ID error, which Weber numbers E16.

Still showing E4?
A booking with a code goes further when it has the code copied exactly, the model and serial from the rating label, and a word on whether the grill still lights, heats or feeds pellets. With those three the office can match the likely part to your grill the same day.
