AEG Washer Error Code E37

E37 means the measurement circuit for dry run protection 1 is reading a constant 0V signal. Dry run protection monitors water presence before allowing the heating element to activate. This error indicates a circuit-level failure, most commonly within the main electronics board, that prevents the safety system from functioning correctly.

It is not recommended to continue using the washer while E37 is active. The dry run protection circuit is a safety system that prevents the heating element from operating without adequate water. Running the machine with this circuit failed could allow the heater to operate unsafely or may cause the washer to halt mid-cycle without warning.

Repair costs vary depending on whether the issue is a wiring fault or a full board replacement is needed. A wiring repair or connector fix may cost relatively little in labor. If the main electronics board requires replacement, parts and labor combined typically range from around $150 to $400 or more, depending on the specific model and local labor rates.

Basic checks such as inspecting the wiring harness for damage and reseating connectors can be done by a confident DIYer. However, if those steps do not resolve the fault, the repair requires replacing the main electronics board, which involves working with internal electrical components. Most homeowners will want a qualified technician to handle the board replacement.

A reset is unlikely to permanently clear E37 because the fault is caused by a hardware failure in the measurement circuit rather than a temporary software or sensor glitch. The error will typically return as soon as the machine attempts to check the dry run protection circuit again. The underlying electrical fault must be resolved first.
