GE Dishwasher Error Code F216

F216 indicates a problem detected in the heater TCO circuit or the AC wiring connections related to the heating system. The machine control board has flagged this circuit because it cannot confirm proper continuity or operation through the heater TCO and associated AC harness. The control board itself is not identified as the source of the fault.

Running the dishwasher with an active F216 code is not recommended. The fault indicates the heater circuit is not operating correctly, which means the dishwasher may not be heating water properly and could fail to sanitize dishes. Additionally, a compromised heater circuit represents a potential safety concern that should be resolved before continued use.

Repair costs vary depending on which component has failed. A replacement TCO part is generally inexpensive, typically in the range of $10 to $40 for the part alone, while a heating element replacement can run $30 to $100 or more for parts. If a technician is needed for diagnosis and labor, total repair costs commonly fall in the range of $100 to $250 depending on your location and the extent of the repair.

Some causes of F216, such as a loose harness connector, can be addressed by a knowledgeable DIYer who is comfortable working safely around appliances. However, because this code involves the AC power side of the heater circuit, always disconnect the dishwasher from power before inspecting any components. Replacing the TCO or repairing damaged wiring is within reach for experienced DIYers, but if you are unsure about working with electrical components, a qualified technician is the safer choice.

A power reset may temporarily clear the code display, but F216 will return if the underlying problem in the heater TCO circuit or AC harness has not been corrected. The code is a symptom of a real circuit fault, and resetting without repairing the root cause will not restore normal heater operation.
