What Do Monogram Washer Error Codes E42 and E45 Mean?
The E42 and E45 error codes on a Monogram washing machine indicate drive motor errors — the motor or motor drive system is operating outside design limits. The control board monitors motor current, speed, and inverter drive feedback signals. E42 typically indicates the motor drive is operating above design limits (overcurrent or overspeed), while E45 indicates a related motor control fault.
When these errors appear, the washer may stop mid-cycle, fail to spin, or produce grinding or straining sounds before stopping.
Common Causes of the E42 / E45 Error Codes
- Overloaded drum – Exceeding the washer’s rated load capacity forces the motor to work harder than its rated limits, triggering overcurrent protection.
- Worn motor bearings – Bearings that have degraded create mechanical drag on the motor, increasing current draw.
- Failed inverter board – The motor speed control inverter has a component failure.
- Worn drive motor – Internal electrical failure of the motor windings.
- Loose motor wiring – Intermittent connection causing erratic motor control.
How to Troubleshoot the E42 / E45 Error Codes
- Reduce load size – If the drum was heavily loaded, remove items. Wash large heavy items (blankets, rugs) separately.
- Reset the washer – Unplug for 60 seconds. After reset, run a small, balanced load and monitor for error recurrence.
- Listen for unusual sounds – Grinding, humming without spinning, or squealing during operation indicate mechanical motor issues.
- Check for drum obstructions – Items like underwire, coins, or small toys can lodge between the drum and tub, adding mechanical resistance to the motor.
