Thermador Range Error Code E:25

E:25 on a Thermador range with WTMC dryer functionality indicates a damaged data table within the control module. The control board cannot read the stored parameters it needs to operate correctly. This is an internal electronics fault rather than a sensor or mechanical issue. Resolution typically requires replacing the control module.

Continuing to operate the appliance with a corrupted data table can result in unpredictable behavior from the control system. It is best to stop using the unit until the faulty control module has been replaced. Using it in this state could lead to further damage or unsafe operation.

Repair costs for E:25 typically involve the price of a replacement control module plus labor for installation. Parts costs for control modules on Thermador appliances generally range from $150 to $450 or more depending on the specific model. With professional labor included, total repair costs commonly fall in the range of $250 to $600 or higher.

The E:25 error requires replacing the control module, which involves working with the main electronics of the appliance. While a knowledgeable DIYer with experience in appliance electronics may be able to perform the replacement, most homeowners will want to call a qualified technician to ensure safe and correct installation.

A simple power reset will not clear E:25 because the fault is caused by corrupted or damaged data stored within the control module itself. The error will return after the reset since the underlying memory issue persists. Control module replacement is required to resolve this fault permanently.
