What E3 means on a ADC washer
The E3 error code on an ADC washer indicates a drain pipe fault. Specifically, the control board has signaled the emptying valve output to deactivate, but the water level sensor inside the drum detects that the water level has not dropped within the pre-established time window. This means the machine expected the drum to empty after the drain valve was told to close or open, but standing water remains, suggesting a failure somewhere in the drain system.
The components most likely involved include the drain valve itself, the drain hose, the pump, and the pressure sensor or water level sensor that reports drum water levels back to the control board. If the drain valve is stuck closed or partially obstructed, water cannot exit the drum. Similarly, a kinked, clogged, or improperly routed drain hose can restrict flow enough to prevent the drum from emptying within the allowed time. A failed drain pump would produce the same result, as it cannot move water out of the machine regardless of valve position.
A secondary but important consideration is the pressure switch or water level sensor. If this sensor is malfunctioning, it may report that water is still present even after the drum has drained correctly, causing a false E3 fault. Diagnosing E3 requires checking physical drainage components first, then verifying that the level sensing system is functioning accurately. The control board offers a prompt to press START to continue the program or press ESC to end it, which can help isolate whether the fault is intermittent or persistent.

Common causes of E3
- 01
Clogged or kinked drain hose
Wiring / connectionA drain hose blocked by lint, debris, or a kink will prevent water from exiting the drum within the required time. Inspect the full length of the hose from the pump outlet to the standpipe for bends, obstructions, or blockages.
- 02
Failed or obstructed drain pump
Part replacementIf the drain pump motor has failed or a foreign object such as a coin or button is lodged in the pump impeller, water cannot be moved out of the drum. Listen for unusual noises from the pump during the drain cycle and inspect the pump filter for debris.
- 03
Stuck or faulty drain valve
Part replacementThe drain valve may be mechanically stuck in the closed position or may have a failed solenoid, preventing it from opening fully to allow water to flow out. Check for proper voltage at the valve solenoid and verify the valve moves freely.
- 04
Faulty pressure switch or water level sensor
Part replacementIf the pressure switch or water level sensor is defective, it may incorrectly report that water is still present in the drum after a successful drain, triggering a false E3 code. Check the sensor hose for blockages and verify the sensor output corresponds accurately to actual water levels.
- 05
Blocked standpipe or household drain
Wiring / connectionA clog in the home standpipe or drain connection can cause water to back up into the drain hose and prevent the machine from emptying. Check for slow draining at the standpipe and clear any household plumbing blockages.
