Error-code hub
Blueridge shows an alphanumeric code on the indoor display, and the 6 codes below are those published in homeowner-facing documentation across the XS, XM, DS and DM ranges. The set is small because Blueridge's public literature is limited. If your code is not here, the model's own manual from your retailer is the right source - do not read across from another brand.
Unit applicability
This table is sourced for Blueridge XS2 Core. If your unit is a different generation or product line not named here, the same display code may vary by generation.
Common codes first
Ranking basis: we do not have failure-frequency telemetry. These are ordered by breadth of affected systems in the SplitAtlas catalog - the documented product line's published model count, whether the same code appears on more than one product line, and any manual applicability notes we hold. This is a breadth ranking, not a popularity claim.
ECC1 is used on multi-zone systems when another indoor unit refrigerant sensor detects leakage. The alarm may show on one zone even though the leak alarm originates at a different indoor unit.
EHC1 is a refrigerant leak alarm from the indoor unit sensor. The XS2A manual says the outdoor compressor stops and the indoor fan starts when the refrigerant sensor detects leakage.
EHC2 combines two problems: the refrigerant sensor is outside its expected working condition and leakage is detected. Treat it as both a leak alarm and a sensor diagnostic.
EHC3 means the refrigerant sensor itself is not operating in the expected range. The manual states the sensor cannot be repaired and must be replaced with the manufacturer-specified part if it malfunctions.
EL0C means the Blueridge unit has detected that the system lacks refrigerant. The same manual also lists low refrigerant from leak or long-term use and too little refrigerant as causes of poor operation.
FHCC means the indoor unit has detected a refrigerant sensor malfunction. The manual says the sensor cannot be repaired and must be replaced with the manufacturer-specified sensor.
Safe first checks
These codes have homeowner-safe steps such as filters, airflow, condensate/drain checks, remote/controller items, or a single safe power reset. If the code returns, stop at the boundary in the card.
Stop using the unit if the code remains after a single safe power reset. Do not open the indoor unit or disconnect the sensor.
Read the full code guidePower cycle once only if safe. If FHCC remains or returns, leave the unit off and do not open the indoor unit.

CL is a normal Blueridge display for the Active Clean function. The manual says the indoor display shows CL while the unit cleans the heat exchanger, then shuts off and cancels the function after about 20 to 45 minutes.
