What the E38 error code actually means

Your AEG washer has detected a problem with an internal safety circuit that monitors whether the machine is running without water, which could damage the pump or motor. The electronic control board is receiving a signal that is stuck in one position and cannot change, so it cannot tell if the protection system is working properly. This error typically requires a technician to inspect the wiring connections or replace the control board.

Questions people ask about E38

What does E38 mean on a AEG washer?
E38 indicates that the measurement circuit for dry run protection sensor 2 is outputting a fixed voltage of either 0V or 5V, with no variation. This tells the control board that the circuit is not functioning correctly and cannot reliably monitor whether the machine is running without water. The fault points to a problem with the control board, the wiring harness, or the sensor itself.
Is it safe to keep using my AEG washer when E38 is showing?
It is not advisable to continue running the washer while E38 is active. The dry run protection circuit is a safety system designed to prevent the pump and motor from overheating when operating without water. With this circuit reporting a fault, the machine may not be able to detect a dangerous dry-run condition, which could lead to further component damage.
How much does it cost to repair an AEG washer E38 error?
Repair costs vary depending on what component is at fault. If only wiring or a connector needs attention, costs may be minimal beyond a service call fee. If the main control board requires replacement, parts and labor combined typically range from $150 to $400 or more, depending on the specific model and local labor rates.
Can I fix E38 on my AEG washer myself?
Some preliminary checks, such as inspecting wiring harness connectors for corrosion or loose pins, can be done by a confident DIYer. However, if the wiring checks out, the next step is replacing the main electronics board, which requires disassembling the machine and working with electrical components. This level of repair is generally best handled by a qualified appliance technician.
Will resetting my AEG washer clear the E38 error?
A power reset may temporarily clear the displayed error, but E38 will return if the underlying fault in the measurement circuit persists. Because this code relates to a hardware failure in the control board circuitry or wiring, a reset does not address the root cause. The fault needs to be diagnosed and repaired properly.
