Condensate Troubleshooting Guide:

PUMP DOES NOT RUN

- Check to see that the power to the system (air conditioner and/or furnace) is on to allow production of

condensate.

- Check that the pump is plugged in and the circuit is active (i.e. fuse or breaker not blown).

- Check the level of water in the reservoir; the level must be within 2” of the reservoir top to activate the

switch. (The inlet tube may be blocked and require cleaning if no water is entering the reservoir).

- If there is a proper amount of water in the reservoir, the float may be stuck due to dirt or algae formation.

(Flush the reservoir with warm water and a mild soap or detergent). See note below.

 

PUMP MOTOR RUNS WITH NO DISCHARGE

- Inspect the discharge tubing for its full length to make sure it is clear; make sure the tubing end is not

plugged.

- Make sure the check valve is not clogged. (If clogged, UNPLUG THE PUMP, remove the fitting and clean

with mild soap or detergent). See note below.

- The discharge port of the impeller chamber may be clogged due to an accumulation of debris. (See

instructions below on how to disassemble unit and clean chamber).

 

NOTE: In case of extreme algae formation, UNPLUG THE PUMP, and fill the reservoir with a commercially

available algaecide. Follow directions for destroying the algae. After the proper waiting period DUMP the

algaecide out of the reservoir. Rinse with water, repeat if necessary. Be careful not to clog the check valve

when starting the pump after this thorough cleaning.
