Possible Causes
Incorrect sensor calibration, Faulty GE water level sensor, Control board misreading sensor, Air leak at tub pressure dome
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
- Check pressure dome: Locate the pressure dome or port on the side of the outer tub where the pressure hose connects. Ensure it is not cracked or clogged with detergent residue. Clean gently if needed.
- Verify hose fit: Make sure the pressure hose is snug on both the tub and sensor fittings. Replace the hose if it is loose or hardened.
- Sensor replacement: If E72 appears repeatedly and hose/dome are good, replace the GE water level/pressure sensor.
- Control reset: After replacement, perform any required calibration or reset procedure described on the unit's tech sheet (often involves entering service mode and running a calibration cycle).
