If your Honeywell Monitor displays a 'Pump failed' message or pump alarm, first, check for and remove any obstructions. Then, press the reset button to clear the alarm. If the problem persists, replace the contaminated water trap filter. Also, ensure that water condensation does not occur inside the unit. As a last resort, the pump itself may need to be replaced.
