Weber E18: the cookbox temperature has dropped
The controller raises E18 when heat drops away from the set point, most often because the lid has been open, wind is pulling heat out, or the pellets are low or poor.

What E18
actually means.
The controller raises E18 when heat drops away from the set point, most often because the lid has been open, wind is pulling heat out, or the pellets are low or poor. You can keep cooking; the notification is a prompt to look for the cause.

What to do when E18 shows on the grillKind of codeTemperature and probes
A probe is sending the controller a reading it cannot trust, or no reading at all: the grill's own temperature sensor coated in smoke and grease, its lead pinched or melted, or a meat probe unplugged, wet or reading far outside what any cook box could reach. The grill then overshoots, stalls or shuts down to be safe. Wiping the sensor once the grill is cold and reseating the probe in its jack are reasonable steps; a sensor that still reads wrong is a visit.

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 E18 on its grills. Follow it to the end: the last card says whether this is a visit.
Press the dial to dismiss the notification and close the lid.
Check the pellet level and quality; a fresh pellet should snap cleanly rather than crumble.
Open the lid briefly to make sure nothing is blocking the temperature sensor inside the cookbox.
If you need to cook with the lid open often, switch to Manual Mode so the grill holds a steady feed rather than overcorrecting.

What not to do
E18 does not mean the fire has gone out, which is E19 or E3. It is also not a sensor failure, which is E8.

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.
