Electrolux Washer Extractor Error Code 52: Charge Circuit
Error code 52 means the DLCU arming circuit for the door lock coil is charged when it should not be. If it cannot be corrected, the manual says to replace the CPU unit.
High: the door lock circuit is behaving wrongly, so the machine must be checked before use.

What does Electrolux Professional error code 52 mean?
The door lock coil is armed by a circuit in the DLCU, which charges up only when the control wants the lock to act. The DLCU checks that this arming circuit is discharged at the times it should be. If it finds the circuit charged when it should not be, it shows ERROR 052 / CHARGE CIRCUIT. The manual attributes it to overloads or defective parts in the DLCU or CPU. It gives one remedy: if the problem cannot be corrected, replace the CPU unit. The check protects the door lock from being driven when it should not be. The wording is general, so a technician starts by confirming that the lock and its wiring are not creating the overload, and then moves to the board if the code returns after a reset. Operators see the machine stop and the door lock behave oddly.

How a technician diagnoses error code 52
- Read the code and confirm ERROR 052.
- Check the lock coil and wiring for overload.
- Reset and see whether the code returns.
- Replace the CPU unit if it cannot be corrected.
- Test the lock through a full cycle.
- The lock coil and arming circuit are control circuits that need isolation before testing.
- Telling an overloaded coil from a failing board needs a meter.
- A new CPU unit must be set up for the machine.
