What the EB3 error code actually means

The EB3 code means your washer is detecting that the power coming from your wall outlet is too low for the machine to run safely. This can happen because of an issue with your home's electrical supply, a faulty outlet, or a problem with the washer's own control board. Until the power supply is confirmed to be adequate and stable, the washer will not operate.

Questions people ask about EB3

What does EB3 mean on a Kenmore washer?
EB3 means the washer has detected incoming AC line voltage below 90 VAC, which is too low for safe operation. The control board monitors supply voltage continuously and halts the machine when voltage drops beneath this threshold. The issue can stem from a low household supply voltage, a faulty outlet or wiring connection, or a failed control board.
Is it safe to keep using my Kenmore washer when EB3 appears?
No, you should not continue running the washer while EB3 is active. Operating appliances under low-voltage conditions can overheat motors and electronic components, potentially causing further damage or creating a safety hazard. Resolve the voltage issue first before resuming use.
How much does it cost to repair a Kenmore washer with an EB3 error?
Costs vary depending on the cause. Fixing a wall outlet or tightening connections is generally inexpensive, typically in the range of $50 to $150 if a licensed electrician is involved. Replacing the control board is more expensive, with parts and labor costs commonly ranging from $150 to $400 depending on the specific model and service rates in your area.
How do I fix the EB3 error on my Kenmore washer?
Start by measuring the voltage at the wall outlet using a multimeter. If the voltage is below 90 VAC, the problem is with your electrical supply, outlet, or circuit, and you should address those issues before running the washer again. If the outlet voltage is above 90 VAC and the error persists, the control board needs to be replaced.
Will resetting my Kenmore washer clear the EB3 error code?
A reset may temporarily clear the code, but it will return if the underlying cause has not been corrected. If the supply voltage is genuinely below 90 VAC or the control board is faulty, the error will reappear as soon as the washer attempts to operate again. Fix the root cause first for a lasting resolution.
