Electrolux Washer Error Code ddo
Drawer reed switch is not closed (dispenser drawer open).
Drawer reed switch is not closed (dispenser drawer open).
First step from the service manual
Make sure the drawer is closed. If the drawer is closed, check that the magnet in the drawer is in the correct position. If the magnet is in the correct position, check the reed switch.

What ddo means on a Electrolux washer
The ddo error code on an Electrolux washer indicates that the dispenser drawer reed switch has not detected a closed position. The reed switch is a small magnetic sensor mounted in the washer cabinet near the dispenser drawer. When the drawer is fully closed, a magnet embedded in the drawer aligns with the reed switch and causes its internal contacts to close, signaling the control board that the drawer is properly seated. If the control board does not receive this closed signal, it generates the ddo fault and may prevent the cycle from advancing.
The most straightforward cause is simply that the dispenser drawer is ajar or not pushed in completely. However, if the drawer appears fully closed and the error persists, the magnet inside the drawer may have shifted out of its correct mounting position. This misalignment means the magnet no longer lines up with the reed switch even when the drawer is fully seated, so the switch contacts never close.
If both the drawer position and the magnet alignment check out as correct, the reed switch itself is the likely culprit. Reed switches can fail due to contact corrosion, physical damage, or general wear over time. A failed switch will not close its contacts regardless of magnet proximity, leaving the control board in a permanent open-signal state. Testing the reed switch with a multimeter for continuity when a magnet is brought near it can confirm whether the switch is functioning correctly.

Common causes of ddo
- 01
Dispenser drawer not fully closed
Wiring / connectionThe drawer may appear closed but not be fully seated. Push the drawer firmly until it stops to ensure it is completely in position.
- 02
Displaced magnet in the drawer
Wiring / connectionThe magnet embedded in the dispenser drawer can shift out of its correct position, preventing it from aligning with the reed switch even when the drawer is closed. Inspect the magnet's mounting location inside the drawer and reseat it if it has moved.
- 03
Failed reed switch
Part replacementThe reed switch in the washer cabinet may have corroded contacts or internal damage, preventing it from closing even when the drawer magnet is properly aligned. Bringing a magnet close to the switch and testing for continuity with a multimeter can confirm failure.
- 04
Damaged or missing drawer magnet
Part replacementIf the magnet has fallen out of the drawer or is cracked, it will not generate sufficient magnetic field to close the reed switch. Inspect the magnet for physical damage or absence.
- 05
Wiring issue on the reed switch circuit
Wiring / connectionA loose connector or damaged wire between the reed switch and the control board can interrupt the closed-drawer signal. Inspect the wiring harness at the reed switch connection for any signs of damage or disconnection.
