What does Blendtec error: reset error detected mean?

A control normally restarts only when power is applied or when it is told to. The Blendtec control also notices when it restarts without being asked, for example after a brief power loss or a processor glitch, and shows Error: Reset error detected. The message tells the operator that the last cycle may have been cut short and that the control restarted. The manual lists it among the Reset Errors for the Stealth 875/885 and Connoisseur 825, with the action to press the cancel button or cycle power by unplugging the blender and plugging it back in, and to contact your Blendtec service agent if the error does not clear. No individual causes are listed. A supply dip, a loose connection or a failing control board could cause it, but those are our likely causes. The display reads exactly Error: Reset error detected.

Possible causes

Likely causes — what usually sits behind error: reset error detected on this control. A technician confirms which one it is before any part is replaced.

Supply dip or brief power loss that restarted the control
Cord or plug loose, so power flickers when the blender is moved
Control board resetting itself because of a failing part

Safe checks before calling for service

✓ What an operator can do

Press the cancel button, or unplug the blender and plug it back in, as the manual says.
Check that the plug is firmly in the outlet and the cord is not pinched.
Try a different outlet and run a short blend.
If it keeps resetting, note how long into the cycle it happens and what else was running nearby, for the service call.

How a technician diagnoses error: reset error detected

Read the error and see how often resets are happening.
Measure the supply voltage at the outlet under load.
Inspect the cord, plug and internal connections for looseness.
Check the control board for signs of heat or damage.
Replace the board or cord that fails testing and run a long loaded test.

! Leave this to a technician

Supply measurements involve live voltage.
Board checks mean opening a base connected to power.
Telling a supply dip from a failing board needs a meter and repeated tests.

Error: Reset error detectedQuestions about Blendtec error: reset error detected

Is Reset error the same as the machine being unplugged?

The control reports it when it restarts unexpectedly. A power loss can cause it, but the manual lists no causes.

Can I keep using the blender?

If a power cycle clears it, yes. If it returns, contact your Blendtec service agent.

What if resets happen mid-blend?

Check the outlet and cord first, and call if it repeats, since a failing board can reset at random.
