Condensate pump motor failure, Pump impeller jammed by debris, Pump float switch stuck, Blocked pump discharge hose

How to Fix / Troubleshooting

Safety first: Turn OFF and unplug the unit before working on the pump or hoses.

Steps to resolve E7:

  • Check discharge hose: Inspect the pump outlet hose for kinks, clogs, or frozen sections. Clear or replace as needed.
  • Access pump assembly: Remove the rear or bottom panel to locate the internal condensate pump (if equipped on your Whynter model).
  • Clean pump reservoir: Remove any standing water, slime, or debris from the pump basin. Ensure the float moves freely up and down.
  • Inspect pump wiring: Confirm the pump's electrical connector is firmly attached to the control board.
  • Test operation: Reassemble, plug in, and run the unit. Listen for the pump cycling. If E7 returns and the pump does not run, the pump assembly likely needs replacement.
