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. Weber grill display What to do when E18 shows on the grill ### Kind of code Temperature 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. ### Usually leads to Pellet grill auger and controller repair Jammed augers, dead hot rods, weak combustion fans, lying probes and failed controllers on pellet grills, traced and replaced with the maker's parts. ### Shows up as Grill Error Code on a Pellet Controller or Digital Panel 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. ### Make Weber Weber grill calls often come from a flame that dropped low mid-cook; the tech starts at the tank, the hose and the regulator. ### Source Weber US Searwood 600 pellet grill owner page, FAQ on error codes Searwood 600 and Searwood XL 600 pellet grills with the Weber Connect digital controller (US owner's guide, 2024). ## Before you book, in this order.

Press the dial to dismiss the notification and close the lid. If it comes back, it needs a visit. ### Why does my Weber show E18 every time I open the lid? An open lid dumps heat and the controller notices the drop. Keep the lid closed, or use Manual Mode for cooks where you need to open it often. ### Can wind cause E18 on my Weber Searwood? Yes. Strong wind pulls heat from the cookbox, and Weber suggests turning the grill so its vents face away from the wind. ### Should I worry if E18 appears once on a cold day? One E18 on a cold or windy day is normal. If it keeps coming back in calm weather with good pellets, have the feed and the sensor checked. --- **[Read on the site: Weber E18: the cookbox temperature has dropped](https://bbqgrillrepair.center/error-codes/weber-e18/)** **[Book a visit with BBQGrillRepair.center](https://bbqgrillrepair.center/schedule/)**
