What this exact manual documents

ErH

Overheat error

Manual meaning
The manual identifies an overheated unit, possibly due to a grease fire or excess fuel.
Safe first move
Hold Power for the documented shutdown, let the grill cool, then complete maintenance and component-position checks before restarting.
Use the fire-pot safety path
ErP

Grill-probe connection error

Manual meaning
The grill-probe wire is not making a connection or the grill probe is broken.
Safe first move
After full cool-down and disconnection, use the model manual to inspect the grill-probe connection. This code is not PB260PSP2’s power-outage lockout.
Diagnose the cooker probe
ErL

Start-up or flame-stability error

Manual meaning
The grill fails to perform its start-up cycle or will not stay lit.
Safe first move
Once cool and unplugged, check component placement, fuel, feed obstruction, grill-probe condition, and fan behavior through the model manual before another start.
Work through the ignition path
NoP

Meat-probe port error

Manual meaning
The meat-probe connection port has a bad connection or the meat probe is damaged.
Safe first move
Reconnect the meat probe at the control-board port and inspect the adapter end and wire. This is a food-probe message, not a cooker sensor fault.
Separate food-probe and cooker-probe care
Err + flashing auger 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
Err + flashing igniter 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 and use the manual’s check before considering a replacement. Do not order an igniter from the code and icon alone.
Check the ignition path first
Err + flashing fan 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. Use the model manual’s airflow and wiring check rather than treating this as a universal fan diagnosis.
Trace the fan symptom safely
Err + flashing pellet icon

Fuel quality or feed alert

Manual meaning
The manual identifies lack of fuel, poor fuel quality, or a grill that will not stay lit.
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
