Electrolux Washer Error Code HE/BE

The HE/BE error code on an Electrolux washer indicates a control relay fault. The control relay is a critical switching component on the main control board that manages power delivery to major components such as the motor, heating element, and pump. When the control board detects an abnormal condition related to relay operation, including a relay that is stuck open, stuck closed, or failing to switch under load, it triggers this fault code to alert the technician that power distribution integrity may be compromised.

The primary diagnostic path for this fault is Test 18, which involves checking the incoming power voltage under load conditions. This is significant because relay faults can sometimes be caused or exacerbated by voltage irregularities at the power supply rather than a faulty relay itself. A relay that receives insufficient voltage may fail to fully close or open, mimicking a hardware failure when the root cause is actually an external power supply issue. Measuring voltage under load rather than at idle helps reveal voltage drop conditions that would not be visible under a static test.

If the incoming power supply passes the load voltage test, attention shifts to the control relay itself, which is typically integrated into the main control board assembly. A relay that has failed internally due to burned contacts, coil degradation, or thermal damage will require board-level repair or full control board replacement. Wiring harness connections between the board and the components the relay controls should also be inspected for corrosion, looseness, or heat damage, as high-resistance connections can place excessive stress on relay contacts.
