What this exact manual documents

ErH

Overheat error

Manual meaning
The manual describes an overheated unit, possibly from a grease fire or excess fuel.
Safe first move
Hold the Power button to turn the grill off, let it cool, then clean and confirm component placement before restarting. If the code remains, contact customer care.
Use the fire-pot safety path
ErP

Grill probe error

Manual meaning
The grill-probe wire is not making a connection or the grill probe is broken.
Safe first move
After the grill is cool and unplugged, inspect the grill-probe wires and reseat their control-board connectors. Treat replacement as a model-specific support decision.
Diagnose the cooker probe
ErL

Start-up cycle did not complete

Manual meaning
The grill fails to perform its start-up cycle.
Safe first move
Once cool and unplugged, check cooking-component placement, fuel, feed obstruction, and grill-probe condition before another start attempt.
Work through the ignition path
NoP

Meat-probe port error

Manual meaning
The meat-probe connection port has a bad connection.
Safe first move
Disconnect and reconnect the meat probe at the control-board port and inspect the adapter end for damage. This refers to the food probe, not the cooker sensor.
Separate food-probe care from cooker-sensor care
Auger error icon

Auger feed or connection alert

Manual meaning
The auger motor is jammed or not making a connection.
Safe first move
Cool and unplug before touching the feed system. Confirm whether pellets are dropping into the burn pot before treating the motor as failed.
Diagnose the auger safely
Igniter error icon

Igniter function or connection alert

Manual meaning
The igniter is not working properly, is not making a connection, or has failed.
Safe first move
Let the grill cool completely, then confirm heat at the burn pot only as the manual directs. Do not order an igniter from the icon alone.
Check the ignition path first
Fan error icon

Fan function or connection alert

Manual meaning
The fan is not working properly or is not making a connection.
Safe first move
Cool and unplug before inspection. Check that the air intake is clear and use the manual’s wiring check rather than treating the alert as a universal fan diagnosis.
Trace heat and airflow first
Pellet error icon

Fuel quality or feed alert

Manual meaning
The manual identifies lack of fuel or poor fuel quality, including pellet obstruction in the feed system.
Safe first move
After cooling, check hopper level and remove damp or poor-quality pellets before treating the auger or controller as the cause.
Trace the pellet path
