HMS 0300-0A00-0001-0005: continuous force detected, heatbed may be stuck
HMS 0300-0A00-0001-0005 means a force sensor sees constant pressure, so the bed may be stuck. What binds a heatbed, and how to free it without damage.

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.
HMS 0300-0A00-0001-0004: external disturbance on heatbed force sensor 1
HMS 0300-0A00-0001-0004 means something touched the bed during a force measurement. Usually a cable, a print or a hand. How to get a clean reading again.
HMS 0300-0A00-0001-0002: heatbed force sensor sensitivity low
HMS 0300-0A00-0001-0002 means a heatbed force sensor is reading weakly. What those sensors do for levelling, and why the plate is the first thing to check.
HMS 0300-0100-0001-000C: heatbed working at full load for too long
HMS 0300-0100-0001-000C means the heatbed has run at full load for too long. Usually a cold room or a draught rather than a failing heater. What to change.
HMS 0300-0100-0001-0006: heatbed sensor short circuit
HMS 0300-0100-0001-0006 means the heatbed sensor reads as shorted. How to measure it, why a pinched cable mimics it, and what the replacement involves.
HMS 0300-0100-0001-0003: heatbed over temperature
HMS 0300-0100-0001-0003 means the heatbed went over temperature and protection cut in. What drives a bed past its limit, and why you should not just reset it.
HMS 0300-0100-0001-0002: heatbed heater open circuit or blown thermal fuse
HMS 0300-0100-0001-0002 means the bed heater reads as open, or the thermal fuse has blown. What a blown fuse tells you, and why it is rarely the real fault.
HMS 0300-0100-0001-0001: heatbed heater short circuit
HMS 0300-0100-0001-0001 means the heatbed heater is drawing more current than it should. Why this is the one bed fault you stop for, and what to check safely.
HMS 0300-C300-0001-0002: filter switch flap current sensor malfunction
HMS 0300-C300-0001-0002 means the filter flap current sensor has failed. Why that stops the flap moving, and what you can realistically do about it now.
HMS 0300-C300-0001-0001: chamber flap current sensor abnormal
HMS 0300-C300-0001-0001 is a current sensor fault on the chamber flap drive. An open circuit or the board, and how to tell which one you are actually facing.
