What the Er:16 error code actually means

Your Thermador range's built-in washing system has detected that water has risen to an unsafe level, so it has shut down to prevent a potential overflow or water damage. This could be caused by a valve not closing properly, a drainage problem, or a faulty water level sensor giving a false reading. A technician will need to run specific diagnostic tests to determine the exact cause before repairs can be made.

Questions people ask about Er:16

What does Er:16 mean on a Thermador range?
Er:16 indicates that the WFR 2460 washer system integrated into the range has detected that the water level has reached its safety threshold. The appliance shuts down normal operation when this occurs to prevent overflow or water damage. Diagnosis requires running the T/P 8 and 9 level test programme to determine whether the elevated level is real or caused by a faulty sensor.
Is Er:16 on a Thermador range a safety hazard?
Yes, this error is treated as a safety condition by the appliance itself because excess water accumulation can lead to overflow, water damage to surrounding cabinetry, or electrical hazards. The unit is designed to halt operation when this threshold is reached. Do not attempt to bypass the fault or continue running the appliance until the root cause has been diagnosed and corrected.
How much does it cost to repair the Er:16 error on a Thermador range?
Repair costs vary depending on the cause. Clearing a blocked drain hose is a low-cost repair, often falling in the range of $75 to $150 for a service call. Replacing a faulty water inlet valve or pressure switch typically costs between $150 and $350 including parts and labor. Control board replacement, if required, can range from $300 to $600 or more depending on part availability.
Can I fix Er:16 on my Thermador range myself?
Some basic checks such as inspecting the drain hose for kinks or blockages are within reach of a knowledgeable DIYer. However, the primary diagnostic step requires running specific internal test programmes (T/P 8 and 9) that typically require service-level access to the control interface. For anything beyond visual drain inspection, a qualified appliance technician is recommended.
Will resetting the Thermador range clear the Er:16 error?
A simple power reset may temporarily clear the fault code from the display, but it will not resolve the underlying cause. If the water level sensor, inlet valve, or drain system has a fault, the error will return during the next operating cycle. A proper repair requires running the T/P 8 and 9 level test programme to identify and correct the root issue.
