Thermador Range Error Code Er:13

Er:13 means the water inlet fill cycle took longer than the allowed time to complete. The range monitors how long it takes water to reach the required level, and when that time limit is exceeded, the control board logs this fault and stops operation. The cause can be a restricted water supply line, a clogged inlet valve screen, low water pressure, or a faulty water level sensor. The first diagnostic step is to run the T/P 11 sensor test programme.

You should not attempt to bypass or continue running water-dependent functions when Er:13 is active. The error exists to prevent overflow or damage that could result from an uncontrolled fill cycle. Address the underlying cause before resuming operation of the water-related features.

Repair costs vary depending on the cause. If the fix involves only cleaning an inlet screen or adjusting the supply line, costs may be minimal. Replacing a water inlet valve typically costs in the range of $80 to $200 for parts alone, while a sensor replacement can fall in a similar range. Professional labor for diagnosis and repair generally adds $100 to $250 or more depending on your location and the complexity of the repair.

Some causes of Er:13 are DIY-friendly, such as checking and straightening the water supply hose, opening a partially closed shutoff valve, or cleaning a clogged inlet screen. However, diagnosing a faulty sensor or replacing the water inlet valve requires running the T/P 11 test programme and working with the water supply connection, which may be better suited to a qualified technician if you are unfamiliar with appliance repair.

A power reset may temporarily clear the displayed fault code, but if the underlying issue with the water supply line or sensor has not been resolved, the error will return as soon as the fill cycle is attempted again. A proper repair of the root cause is required to permanently clear Er:13.
