What the -C- error code actually means

The -C- display is not a problem or error. It simply means your washer is successfully communicating with a special programming tool called a Microwand that technicians use to adjust settings or run diagnostics. If you see this and no technician is present, just unplug the machine briefly and plug it back in to clear the display.

Questions people ask about -C-

What does -C- mean on a Speed Queen washer?
-C- is a status confirmation code that appears during Microwand communication. It indicates that the communication sequence between the Microwand programming tool and the washer's control board is working correctly. This is not an error or fault code. No repair is needed when this code appears in the context of a technician using a Microwand device.
Is it safe to use my Speed Queen washer when -C- is showing?
The -C- code itself does not indicate a mechanical or electrical fault, so the washer is not in a dangerous state. However, if the display is stuck on -C- and the machine is not responding to normal controls, you should avoid running a wash cycle until the display clears. A simple power cycle is usually all that is needed to restore normal operation.
How much does it cost to fix a -C- code on a Speed Queen washer?
In most cases there is no repair cost associated with -C- because it is a status indicator, not a fault. If a technician visit is needed to properly terminate a Microwand session or inspect the control board, a standard diagnostic service call typically ranges from $75 to $150 depending on your location and the service provider. Parts are not expected to be required for this condition.
How do I clear the -C- code on my Speed Queen washer?
If -C- is displaying outside of an active Microwand session, unplug the washer from the power outlet for at least 60 seconds, then plug it back in. This power cycle resets the control board and clears the communication status flag. If the code returns repeatedly without a Microwand device present, having a technician inspect the control board is advisable.
Will resetting my Speed Queen washer clear the -C- code?
Yes, a power cycle reset will typically clear the -C- display if it has persisted after a Microwand session. Unplug the unit for 60 seconds and then restore power. Because -C- is a communication status indicator rather than a fault code, it does not require any special reset procedure or service tool to clear.
