What the i55 error code actually means

Your Electrolux dishwasher detected that the electrical power reaching its motor control board dropped too low to run the wash motor safely, so it paused the cycle to protect itself. This can happen because of a problem with the power supply coming into your home or a fault inside the dishwasher's motor control board. The good news is that the dishwasher will try to resume the cycle on its own once the power level returns to normal.

Questions people ask about i55

What does i55 mean on a Electrolux dishwasher?
The i55 code means the motor control board has detected that its DC bus voltage (Vbat) has dropped below 225VDC, which is too low to safely run the wash motor. The dishwasher pauses the cycle automatically when this happens. The code will clear on its own once the DC voltage recovers above 260VDC. The most likely causes are low mains supply voltage or a faulty motor control board.
Is it safe to keep using my dishwasher when the i55 code appears?
The dishwasher is designed to pause the cycle automatically when i55 triggers, which prevents damage to the motor and drive components. However, repeatedly running the appliance while the underlying voltage issue persists can stress the motor control board over time. It is best to identify and resolve the root cause before continuing regular use.
How much does it cost to repair an i55 error on an Electrolux dishwasher?
If the problem is a wiring or electrical supply issue, costs may be limited to an electrician service call, typically in the range of $75 to $200 depending on your area. If the motor control board needs replacement, parts and labor combined can range from $150 to $400 or more depending on the specific model and local labor rates. Getting a diagnosis before committing to parts replacement is recommended.
Can I fix the i55 error myself?
You can start by checking whether the outlet voltage is correct and whether the dishwasher's circuit is overloaded or shared with other high-draw appliances. If the power supply appears normal and the error keeps returning, the motor control board likely needs professional diagnosis and replacement. Working inside the dishwasher's control compartment involves components that can store dangerous DC voltages, so use caution.
Will resetting the dishwasher clear the i55 error?
The i55 error is designed to clear automatically once the DC bus voltage recovers above 260VDC, so a power reset may temporarily clear the display. However, if the underlying cause, such as low mains voltage or a faulty motor control board, is not addressed, the error will return during the next cycle. A reset alone is not a fix.
