just installed my costway ep24618us and water is leaking out from the bottom onto my floor. did i break it?

Diagnosis

The leaking you are experiencing with your Costway EP24618US is likely not a sign of a broken unit, but rather a failure in the condensate management system. Portable air conditioners remove moisture from the air as they cool; this water collects in an internal drip tray. While this model features an "auto-evaporation" system that vents some moisture out through the exhaust hose, high humidity levels can cause the internal pan to overflow faster than the unit can evaporate the water. When the internal reservoir reaches maximum capacity, the water seeks the path of least resistance, which is often the overflow gap around the lower drain plug or the base of the chassis. If you see a steady puddle forming directly underneath the rear of the unit, it confirms that the internal pan is saturated. This typically happens during the first few hours of operation in a humid room or if the unit is not perfectly level, causing the water to pool against the side of the pan rather than flowing toward the drain port.

How to Fix It

To stop the leaking and properly manage the condensate, you must transition from auto-evaporation to manual drainage. Follow these precise steps:

1. Power down the unit completely and unplug it from the wall outlet to avoid electrical hazards while handling water.
2. Locate the lower drain plug on the back of the chassis. This is a small rubber stopper located near the bottom edge of the unit.
3. Place a shallow drip tray or a thick towel directly beneath the plug to catch the initial surge of water.
4. Firmly pull the rubber plug straight out. Be careful not to lose the plug, as it is required if you ever move the unit.
5. Insert the provided transparent plastic drain hose firmly into the drain port. Ensure the hose is seated deeply enough that it cannot slip out due to water pressure.
6. Route the hose to a floor drain or into a large plastic container (at least 2 gallons). Ensure the hose maintains a constant downward slope; if the hose loops upward at any point, gravity will stop the flow and the unit will leak from the bottom again.
7. Level the unit using a bubble level. If the unit tilts forward or to the side, the water may bypass the drain port and leak onto the floor.

If That Didn't Work

• Check for a clogged internal drain line. Use a flexible pipe cleaner or a thin zip-tie to gently probe the drain port. Dust and lint can accumulate into a "sludge" that blocks the water from exiting the pan even when the plug is removed.
• Inspect the chassis for a cracked drip tray. If water is leaking from a spot other than the drain plug, the internal plastic pan may have a stress fracture. This requires removing the outer casing to inspect the pan; if cracked, apply a waterproof silicone sealant to the fissure.
• Verify the exhaust hose seal. Sometimes water condenses inside the large exhaust hose and drips back into the unit or leaks from the hose coupling. Ensure the exhaust hose is angled slightly upward toward the window so that any condensation flows back into the internal reservoir rather than pooling at the connection point.
• Perform a hard reset of the sensor. If the "P1" or "FL" (Full) error code is appearing but the pan is empty, the float switch may be stuck. Gently shake the unit or tilt it slightly to dislodge the float sensor.

Heads Up

• Never operate the unit on a thick carpet or rug without a plastic drip tray underneath; the carpet can trap moisture against the base, leading to rust or mold.
• Empty your collection bucket daily. If the bucket overflows, the hose will back up and cause the unit to leak from the bottom again.
• Clean the air filters every two weeks. Clogged filters reduce airflow, which can lead to excessive ice buildup on the evaporator coils; when this ice melts, it can overwhelm the drain pan.
• Always replace the rubber drain plug before transporting the unit to avoid spilling gallons of trapped water across your floor.
