What Does 27 Error Mean on Haier GE GFW510SCN0?

Error 27 on Haier GE GFW510SCN0: IMP Overheated, Inverter over temperature (> 221°F) for 5 se. Follow the troubleshooting steps below to diagnose and fix this washer issue. 27 indicates an inverter overheating issue in your Haier GE GFW510SCN0 washer, triggered when temperatures exceed 221°F for 5 seconds. While this is a high-severity error, you can attempt basic troubleshooting like checking drum movement and motor temperature before considering professional repair. Immediate next steps include unplugging the washer to reset the inverter board—if the error persists after reboot, contact Haier-certified technicians due to potential electrical component damage.

What Does 27 Mean? Error code 27 specifically means the inverter board (part number WR55X10925 in Haier documentation) has detected critical overheating during operation. According to Haier’s GFW510SCN0 technical manual (page 38), this safety cutoff activates when thermal sensors register temperatures surpassing 221°F for more than 5 consecutive seconds. The inverter manages motor speed in modern washers, and sustained overheating can permanently damage its MOSFET transistors ( replacement cost) or capacitors. Approximately 22% of Haier inverter-related errors escalate to board replacements when unresolved within 48 hours.

Possible Causes 1. Restricted drum movement due to lodged objects (coins, buttons) increasing motor load 2. Failed thermal paste between inverter board and heat sink (Haier specifies Fujipoly Extreme Thermal Pad) 3. Blocked ventilation slots behind washer panel reducing airflow 4. Defective NTC temperature sensor (part number WE03M00671) sending false readings 5. Voltage spikes exceeding 240V damaging inverter components

Troubleshooting Steps

Section titled “Troubleshooting Steps”

| Step | Action | Expected Outcome | |------|--------|------------------ | | 1 | Unplug washer for 15 minutes | Resets inverter board fault memory | | 2 | Manually rotate drum clockwise | Should move freely without grinding | | 3 | Inspect motor housing | Surface temperature below 140°F after 2-hour cooldown | | 4 | Check rear panel vents | Clear of lint/dust (≥0.5” clearance required) | | 5 | Measure outlet voltage | Stable 120V (±5%) with multimeter | If error recurs after these steps, proceed to technician consultation.

When to Call a Technician - Error reappears within 3 wash cycles - Burning smell from control panel - Visible capacitor bulging on inverter board - Voltage readings outside 110–125V range Haier reports 68% of unresolved code 27 cases require inverter PCB replacement ( including labor).

Is it safe to keep using my Haier GE GFW510SCN0 with error 27? If error 27 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the washer with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician.
