On a True TCIM ice machine, the maintenance reminder is reset through SERVICE, then the reset control for the maintenance actually performed and YES. Do this after the required maintenance has been completed. The reset changes a counter; it does not clean the machine, remove scale or explain a separate fault message.
True publishes this sequence in Maintenance Reminder Reset, document 229219, revision B, dated July 25, 2025. Its model field names TCIM and covers all voltages. It is not a reset procedure for True reach-in refrigerators or prep tables.
The screen sequence
Start from the normal home screen. Open SERVICE. The Counters screen has separate rows for Last evaporator clean, Last air filter clean and Water filter usage. Select reset only for the work completed. Check the counter named in the confirmation dialog before choosing YES. Use the back control to return to the home screen when the counter has reset.
The document illustrates the buttons, so a machine with a different interface needs its matching instructions. If you cannot find that Counters screen, stop there. This guide does not call for opening the cabinet or cycling power until a message disappears.
Keep the maintenance record separate
Write down what work was completed and when. The counter display and the maintenance record answer different questions: the screen tracks elapsed days or water usage, while the record describes the work. Resetting an unrelated row makes its history inaccurate for the next shift. Completing an air-filter clean does not justify resetting the evaporator-clean or water-filter counter.
There is no cleaning interval or chemical dose in this reset bulletin. Obtain those details from the maintenance instructions for the installed machine. Keep this reset bulletin alongside the separate cleaning instructions for the equipment.
If the machine also has poor ice production, leakage or another alert, record that symptom separately. A cleared maintenance reminder is not a diagnosis of any of those conditions. Photograph the display before clearing it, particularly when more than one message is present.
For a persistent TCIM problem, contact True or your ice-machine service provider with the full model and exact message. State which maintenance was performed and which counter was reset. ADRIUM’s True refrigeration service page covers reach-ins, prep tables and other listed refrigeration equipment; this guide does not establish TCIM service availability.
