Z Grills – LEr Error & Fire Out

Z Grills Error Overview

The Z Grills controller has 4 errors that can be displayed:

Never turn the grill on with the lid closed, especially if an error occurred.

LEr – What it Means

The LEr error occurs if the grill has run for more than 20 minutes below 65ºC / 150ºF, indicating that the fire has gone out, or hasn’t been successfully ignited.

LEr most commonly occurs due to the following reasons:

  • Grill runs out of pellets mid cook
  • Grill hasn’t established a fire during startup (in first 10-15min)
  • Fire goes out due to moist pellets
  • Fire goes out due to too much ash in the fire-pot
  • Fire goes out after turning to low temp when operating at high temp
  • Fire goes out due to low temperature operation (Smoke or 82ºC) in hot weather

LEr – What to do (Important)

Never turn the grill back on until opening the grill lid and completing a full investigation as outlined below to find the cause.
Simply turning the grill back on is dangerous as the fire-pot may be full of pellets. The result can be a huge fire and even explosion as gases released from all the pellets ignite.

If LEr is displayed on the controller display, follow these steps:

  1. Turn off the grill and unplug from power
  2. Open the grill lid
  3. Take out the grill racks, grease tray and baffle plate so you can see the fire-pot
  4. Review the information below and the troubleshooting flowchart to diagnose the reason for the LEr

Huge Smoke Cloud (during cook)

If you notice a huge release of smoke during a cook, and the temperature is much lower than the controller setting, a fire-out may have occurred.

There are a few possible reasons for this as outlined below.

  • If the weather is hot and the controller was set to Smoke or 82ºC check out the section Fire-out (With Smoke) below.
  • If the weather is cool, or the grill is set to 107ºC in hot weather, check out the section Moist Pellet Fire-out (With Smoke) below.
  • If the grill was turned from a high temperature down to a much lower temperature check out the section Fire-out (With Smoke) below.

Fire-out (With Smoke)

If the fire-out occurs in hot weather (normally 30ºC or higher) when running on Smoke or 82ºC, it is most likely due to the inability of the grill to maintain a low enough temperature while still keeping the fire alight.

Another possibility is when the target temperature is changed to a much lower setting than the current grill temperature.

In most cases the grill will reignite the pellets when the temperature drops below 65ºC, resulting in a huge cloud of smoke. If this happens follow these steps:

  • Carefully open the grill lid
  • Turn the grill to shut down cycle
  • If the smoke is not too much to get close to the grill, take out the grill racks, grease tray and baffle plate so you can see the fire-pot.
  • Empty out as many wood pellets from the hopper as possible. Temporarily remove the protective guard if required to scoop the pellets out. Do not use a vacuum as it may suck embers into the hopper. This is just a precaution in case the huge fire in the fire-pot leads to any back burning and a smokey hopper.
  • If still planning to cook, wait until the fire has significantly died down (but still alight) and turn the controller back to 107ºC.
  • If not planning to cook, wait until the pellets have fully burnt out and the grill has cooled down then complete a clean out of the fire-pot.
  • Run the grill at minimum of 107ºC in hot weather. It may also be possible to run at the lower temperatures if the grill is in the shade, as direct sunlight significantly increases the grill temperature.

If a fire-out occurs in hot weather when the grill is set to 107ºC, check out the section Moist Pellet Fire-out (With Smoke) below.

Fire-out (No Smoke)

If the fire-out occurs in hot weather (normally 30ºC or higher) when running on Smoke or 82ºC, it is most likely due to the inability of the grill to maintain a low enough temperature while still keeping the fire alight.

Another possibility is when the target temperature is changed to a much lower setting than the current grill temperature.

If you notice the temperature has dropped below 70ºC but no smoke is visible and LEr is not displayed on the controller screen, follow these steps:

  • Carefully open the grill lid.
  • Turn the grill to shut down cycle.
  • Remove the grill racks, grease tray and baffle to check the fire-pot.
  • If the fire-pot is full, or overflowing with wood pellets, scoop most of them out with a metal spoon before starting the grill as normal. Do NOT use a vacuum as there may still be hot embers in the fire-pot.
  • Startup the grill as normal, but then set to at minimum of 107ºC in hot weather. It may also be possible to run at the lower temperatures if the grill is in the shade as direct sunlight can significant increases the grill temperature leading to a hot weather fire-out situation.

Moist Pellet Fire-out (No Smoke)

If the fire goes out in cool weather, or in hot weather at 107ºC or higher temperature setting, it is most likely due to moist pellets. Click here to learn more about wood pellets and how to store them.

If the temperature has dropped well below the temperature setting and is rapidly falling, but there is no sign of smoke or fire, follow these steps:

  • Carefully open the grill lid.
  • Turn the controller setting to Shut Down Cycle.
  • Take out the grill racks, grease tray and baffle plate so you can see the fire-pot.
  • If there are lots of pellets in the fire-pot, scoop out as many as possible using a metal spoon. Do NOT use a vacuum as there may still be hot embers in the fire-pot.
  • Empty out as many wood pellets from the hopper as possible. Temporarily remove the protective guard if required to scoop the pellets out. Do not use a vacuum as it may suck embers into the hopper.
  • Start the grill up as normal and once there is a fire in the fire-pot, turn the controller to HIGH setting. This will more quickly dump all the pellets into the fire-pot out to allow them to burn off.
  • Leave on the HIGH setting with the lid open until there are no more pellets dropping into the fire-pot (auger feed tube is empty).
  • Turn the controller to Shut Down Cycle
  • Once the fire has started to die down, turn the controller to Shut Down Cycle. If the grill is left on HIGH eventually the fire will die out and the controller will show a LEr error, which is normal.
  • Once the grill has switched off and cooled down vacuum out the fire-pot and auger entry.
  • Pour some fresh, dry pellets into the hopper and go through the initial startup process to prime the auger tube with pellets.

Moist Pellet Fire-out (With Smoke)

If the fire goes out in cool weather, or in hot weather at 107ºC or higher temperature setting, it is most likely due to moist pellets. Click here to learn more about wood pellets and how to store them.

If the pellets have already re-ignited and there is lots of smoke (much more than normal) and LEr is not already displayed on the controller, follow these steps:

  • Carefully open the grill lid.
  • Turn the grill to Shut Down
  • If the smoke is not too much to get close to the grill, take out the grill racks, grease tray and baffle plate so you can see the fire-pot.
  • Empty out as many wood pellets from the hopper as possible. Temporarily remove the protective guard if required to scoop/vacuum the pellets out. This is just a precaution in case the huge fire in the fire-pot leads to any back burning and a smokey hopper.
  • Wait until the majority of the pellets in the fire-pot have burnt out, then turn the controller to HIGH setting. This will more quickly dump all the pellets into the fire-pot out to allow them to burn off.
  • Leave on the HIGH setting with the lid open until there are no more pellets dropping into the fire-pot (auger feed tube is empty).
  • Once the fire has started to die down, turn the controller to Shut Down Cycle. If the grill is left on HIGH eventually the fire will die out and the controller will show a LEr error, which is normal.
  • Once the grill has switched off and cooled down vacuum out the fire-pot and auger entry.
  • Pour some fresh, dry pellets into the hopper and go through the initial startup process to prime the auger tube with pellets.

If the weather is hot and the controller was set to Smoke or 82ºC check out the section Fire-out (With Smoke) above.

Ran Out of Pellets

If you ran out of pellets then complete the initial startup procedure again, like the first time the grill was used. Check out the video below for more information.
