Questions people ask about Er:24

What does Er:24 mean on a Vision washer?
Er:24 indicates that the power supply relay connecting the control board to the inverter has been detected as damaged or stuck. The relay controls high-voltage power delivery to the motor drive system. The washer stops operation when this fault is detected to prevent damage to the inverter or motor. Replacing the control board is the recommended fix.
Will resetting the washer clear the Er:24 error?
A power reset may temporarily clear the error code, but if the relay is physically damaged or stuck, the fault will return as soon as the machine attempts to power the inverter again. A reset does not repair the underlying relay failure. The control board will need to be replaced to resolve the issue permanently.
How much does it cost to repair Er:24 on a Vision washer?
The main cost is the replacement control board, which typically ranges from around $80 to $250 or more depending on the specific model. If you hire a technician, labor costs will add to the total, generally bringing the repair into the $150 to $400 range. Getting a repair estimate before proceeding is advisable to compare against the cost of replacement.
Can I fix Er:24 myself on a Vision washer?
The repair requires replacing the main control board, which involves working near high-voltage components. Technicians with experience in appliance electronics can perform this repair, but it is not recommended for general DIYers without electrical training. Before replacing the board, check that wiring harness connectors are fully seated and free of corrosion.
Is it safe to continue using my Vision washer when Er:24 is displayed?
No, it is not safe to continue operating the washer with Er:24 active. A relay stuck in the closed position can leave the inverter energized when it should be off, creating a risk of overheating or electrical damage. Discontinue use until the control board has been inspected and replaced as needed.
