Prusa Error 17831: HEPA Filter Nearing End of Life
Prusa error 17831 warns the HEPA filter is near end of life. Why the counter runs on printing hours, not months, and what you lose when it finally expires.
Category: Error codes
Machine error codes explained: Bambu HMS codes, MINTEMP and MAXTEMP, thermal runaway, homing and probe failures. What the code means, and what to check first.
Prusa Error 13613: USB Flash Drive File System Error
Prusa error 13613 is a USB drive file system error. Why FAT32 is a hard requirement rather than a preference, and why new large drives fail most often.
Prusa Error 13836: Filament Loading Timed Out
Prusa error 13836 means filament loading timed out. The tip, the spool and the sensor account for nearly all of them, and each one is cheap to put right.
Prusa Error 17108: Stuck Filament Detected
Prusa error 17108 means filament is stuck in the XL Nextruder. Where it seizes, what the removed tip tells you, and how to avoid making the jam worse.
Prusa Error 13812: Unable to Home the Printer
Prusa error 13812 means the printer could not home itself. X, Y and Z are sensed three different ways, so watching which axis fails narrows it down fast.
Prusa Error 13811: Repeated Collision Detected
Prusa error 13811 is repeated collision detection on a Prusa. How to read where the crashes happen, and when resuming is reasonable rather than harmful.
Prusa Error 13816: Print Fan Not Spinning
Prusa error 13816 means the part cooling fan has stopped turning. What it costs your print by material, and why the air duct matters as much as the fan itself.
Prusa Error 13828: Hotend Fan Not Spinning
Prusa error 13828 means the hotend fan has stopped turning. Why it halts the print, how to tell it from the part fan, and the order that finds the fault.
Prusa Error 13310: MMU Port Overcurrent
Prusa error 13310 is overcurrent on the MMU port. Disconnect the MMU first, then work out whether the unit itself, the cable or the board port is at fault.
Prusa Error 13203: Thermal Runaway on the Heatbed
Prusa error 13203 is thermal runaway on the heatbed: the heater ran but the sensor stopped tracking it. It is a safety stop and should never be bypassed.
