Error E45 in Electrolux washing machine

Error E45 in Electrolux washing machine

Error: E45

Description: The E45 code can indicate problems related to the door closure (blocapuertas) or faults in the UBL/triac (simistor) circuit on the electronic board. In some models E43 and E45 are related to the triac for the door lock; in others the fault can come from damaged board components or poor connections.

Causes

• Faulty or improperly closing door lock / latch (blocapuertas).
• Defective triac / simistor (UBL) or other components on the electronic control board.
• Loose, damaged or corroded wiring and connectors between the door lock and control PCB.
• Mechanical obstruction preventing the door from closing correctly.
• Intermittent electronic faults on the control board.

Diagnosis & troubleshooting

Quick checks (user-level)

• Unplug the machine or switch off the power before any inspection.
• Open and close the door firmly several times to ensure correct engagement of the lock.
• Look for visible obstructions, debris or damage on the door seal and latch.
• Reset the washer by disconnecting power for 1–2 minutes and plugging it back in; run a short program to see if the code returns.

Component checks (intermediate/technician)

• Inspect the door lock assembly (blocapuertas) for broken parts, burned contacts or mechanical wear.
• Check wiring and connectors between the door lock and the control board for loose contacts, corrosion or breaks.
• Visually examine the control PCB for burned components, swollen capacitors or damaged triacs/simistors.
• If equipped and if you have technical skill, measure continuity of the door lock and test the triac/UBL circuit following safety procedures. Do not attempt live measurements unless experienced.

Step-by-step troubleshooting procedure

1. Switch off and unplug the appliance.
2. Visually inspect the door latch and strike for damage or foreign objects; clean if necessary.
3. Reconnect power and try a firm door open/close; attempt to start a program to confirm whether E45 reappears.
4. If the code persists, remove the top/front panel (model dependent) and check the door lock connector and wiring for secure fit and damage.
5. Inspect the PCB for obvious faults (burn marks, cracked components). If found, the board or affected components may need replacement.
6. If you do not find visible damage and you are not trained in electronics, stop and contact a qualified technician for further diagnosis (triac/simistor replacement or board repair may be required).

Possible solutions and repairs

• Replace a defective door lock / blocapuertas assembly.
• Repair or replace damaged wiring and secure loose connectors.
• Repair or replace the electronic control board if the triac/UBL or other components are faulty.
• Clear any mechanical obstruction preventing correct door closure.
• When in doubt or when repairs involve the PCB, seek professional service to avoid electrical hazard and incorrect repairs.

Safety and when to call a technician

Important: Work on the control board and its components involves electrical risk. If you are not experienced with appliance electronics, contact an authorized service center or qualified technician. These professionals can diagnose board-level faults, replace triacs/simistors or the PCB, and ensure safe, correct repairs.

More tips

If you cannot eliminate the E45 error after following the checks above, we recommend contacting the nearest Electrolux technical service or a specialist. They can diagnose and solve the problem quickly and efficiently.
