What the H2/B2 error code actually means

Your Electrolux washer is detecting that the electrical voltage coming into it from your home's wiring is too high, which could damage the machine. This is usually a problem with your home's electrical supply rather than the washer itself. You should have an electrician check the voltage at your outlet before running the washer again.

Questions people ask about H2/B2

What does H2/B2 mean on a Electrolux washer?
H2/B2 indicates that the washer's control board has detected incoming supply voltage that is too high. The machine monitors the AC line voltage continuously, and this code triggers when that voltage exceeds the acceptable threshold. It is a power supply fault, meaning the issue originates from the electrical supply rather than a component inside the washer itself. The recommended first diagnostic step is to check the incoming power voltage under load using test (18).
Is it safe to use my washer while it shows H2/B2?
No, you should not continue operating the washer while this code is active. An overvoltage condition can damage the control board, motor, and other internal components. Stop using the machine and have the incoming supply voltage checked before running another cycle.
How much does it cost to fix a H2/B2 error on an Electrolux washer?
If the problem is a utility supply issue, the cost may be little to nothing if the utility company is responsible for the correction. Electrician fees to inspect and repair household wiring or panel connections typically range from $100 to $400 or more depending on the scope of work. If a control board replacement is required, parts and labor costs can range from $200 to $500 depending on the specific model and service rates in your area.
Can I fix the H2/B2 error myself?
Diagnosing this error requires measuring the incoming AC voltage at the washer's power inlet while the machine is under load, which involves working near live electrical connections. If the issue is at the utility level or inside the main electrical panel, a licensed electrician should handle the repair. If the control board is identified as the cause after confirming correct supply voltage, a qualified technician should replace it.
Will resetting the washer clear the H2/B2 error?
A reset may temporarily clear the code, but if the root cause is an ongoing overvoltage condition in your home's electrical supply, the fault will return as soon as the washer attempts to operate again. The underlying voltage issue must be identified and corrected first for the error to stay cleared.
