How the ice machine detects WTD Reset

The control in your ice maker runs a program all the time, and part of that program watches for problems in the way the board talks to other parts. If the conversation stops and the program cannot recover, the control restarts itself in software. That restart is what WTD Reset reports.

The reset is a protection. A control that has lost its link could act on stale data, so restarting returns it to a known state. A brief power interruption can trigger the same thing, since the board may lose its footing for a moment. A one-off reset after a flicker is common sense to expect, but repeated resets point to a weak link or a control board that is failing.

Likely causes of WTD Reset

• A power interruption that upset the control
• A communication problem between the board and another part
• A control board that is starting to fail

Can you keep using the ice machine with WTD Reset?

Yes, you can keep using the ice maker if it runs normally after the reset. Watch it for a few days and note whether the message returns. If it resets again and again, stalls, or you see leaks, heat or odd smells, switch it off at the breaker and have it looked at.

What you can safely check

1. If the unit is making noise, smells hot or leaks, switch it off at the breaker and stop here.
2. Otherwise, leave it plugged in and let it finish its restart.
3. Check that the unit is running normally and making ice.
4. Note the time of the message and whether the power flickered.
5. If WTD Reset repeats, call us and give us those times.
