Condensate Pump Troubleshooting

A condensate pump may be necessary if the drain point is above the level of the condensate drain on the heat pump water heater. A condensate pump failure detect is provided with the heat pump water heater control. Follow the instructions in the installation and operation manual for connection of the condensate pump failure switch to the heat pump control.

Should the condensate pump fail to operate and clear the condensate from the pump reservoir, the float switch provided with the pump will open. The heat pump control will detect condensate pump failure and shut off the heat pump in order to stop condensate from being produced. “HEAT PUMP FAULT” will be displayed on the user interface and the heat pump will not operate until the fault is cleared. By checking the MAINTENANCE DISPLAY, the fault can be narrowed down. For

a condensate pump failure, the MAINTENANCE DISPLAY will indicate CONDENSATE DRAIN ALARM.

In order to determine the cause of the condensate drain alarm, first ensure that the condensate pump has power. Check that the condensate pump is plugged into an outlet and that the socket that the condensate pump is plugged into is powered. If the pump has power, check the outlet tubing for clogs or kinks that could prevent flow of condensate. Also check the pump inlet in the sump for debris that might block flow. Follow the condensate pump manufacturer’s instructions for seperating the pump section from the tank.

If condensate pump appears to be functioning properly but is unable to clear the condensate from the tank, make sure the height of the discharge point does not exceed the pump manufacturer’s specification. Consult the manufacturer’s literature for this information.

Condensate Drain Maintenance

Condensate may be produced when the heat pump runs, depending on the amount of humidity in the air. If the relative humidity is high, the amount

of condensate can exceed 20 oz per hour. The condensate is collected in a plastic pan under the evaporator. Two drain ports are provided for connection of primary and secondary drain lines. 1/2 inch PVC is recommended for connection to the drain ports. The condensate pan, drain ports and lines should be inspected and cleaned periodically. Shut off power to the appliance before performing any maintenance or repair. Access to the drain pan can be gained by removing right side of louver panel. The black plastic pan is inside located below the evaporator and the two drain ports are located toward the back of the unit. Wipe the inside of the condensate pan with a clean rag to remove any debris or algea that may be present. Use an old toothbrush or a bottle brush to clean the inside of the two drain ports. Flush the ports with a small amount of clean water. Clean the condensate pump, if one is installed, in accordance with the manufacturer’s instructions.

Disposal of Condensate

Condensate should be disposed of in accordance with any applicable local codes that may exist. Guidelines for HVAC systems are applicable to the heat pump water heater.

Inspection/Cleaning of the Condensate Drain Pan & Condensate Drain Lines

IMPORTANT: Before attempting to clean or replace the condensate drain pan or lines press the power button to place the water heater in Standby Mode and shut-off power to the water heater at the circuit breaker/fuse box.

1.Remove the access panel (fan side) by loosening the screws securing it to the unit.

2.Check the condensate drain pan and drain lines for any dirt or debris that might interfere with proper drainage. Wipe out any dirt or debris with a damp cloth.

3.Once the condensate drain pan and lines have been inspected/cleaned, secure the access panel to the water heater.

4.Restore power to the water heater and press the power button to turn the water heater on. NOTE: The water heater will conduct an eight (8) minute system diagnostic prior to operation.
