The lid of a pellet grill's hopper raised on a sunny patio, a low layer of wood pellets inside the grill's hopper with the auger opening at the bottom just visible, nobody near it.

Weber E21: the hopper is running low on pellets

Searwood models with a fuel gauge warn you before the hopper runs dry so a long cook is not interrupted.

What E21
actually means.

Searwood models with a fuel gauge warn you before the hopper runs dry so a long cook is not interrupted. It is a prompt to refill, not a sign that anything has broken.

What to do when E21 shows on the grill

Before you book,
in this order.

Each step comes from Weber's own guidance for E21 on its grills. Follow it to the end: the last card says whether this is a visit.

01

Press the dial to dismiss the notification.

02

Refill the hopper with fresh, dry pellets.

03

If E21 keeps showing with a full hopper, wipe the fuel sensor lens with a soft dry cloth, not your fingers, and book a visit if it still persists over several cooks.

Still there?

It usually turns into pellet grill auger and controller repair. Book with the code and the model number.

What not to do

E21 does not mean the gauge has failed, which is E9, or that its lens is dirty, which is E20. A full hopper that still shows E21 points to one of those.

Questions
about E21.

Can I clear E21 myself?
Press the dial to dismiss the notification. If it comes back, it needs a visit.
How long can my Weber keep cooking after E21?
It depends on your temperature and how many pellets are left. Refill soon, because a dry hopper leads to a lost flame.
Why does my Weber show E21 when the hopper looks full?
Dust on the fuel sensor lens can make it read low. Wipe it with a soft dry cloth; if the notification stays, the gauge needs checking.
Do all Weber pellet grills show E21?
No. Weber lists E21 for select models only, those fitted with a fuel gauge.

Back to your everyday

Still showing E21?

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.
