Symptoms
- Water pooling under or around the unit
- Wet spot on the floor near the bucket area
- Bucket overflows before the auto-shutoff triggers
- Drips from the back or bottom of the unit
Likely causes
- CommonBucket not seated squarelyA crooked bucket can let water spill over the edge instead of filling evenly.
- CommonCracked or warped bucketAge and handling can crack the plastic, letting water seep out.
- PossibleFloat switch not shutting the unit off before overflowA stuck or dirty float can fail to stop the unit in time.
- PossibleContinuous drain hose not connected or draining backwardIf a drain hose is installed above the unit's drain level, water can back up.
What to do
- Remove the bucket and inspect it closely for cracks, especially near the corners and handle.
- Reseat the bucket squarely, making sure it clicks fully into place.
- Clean the float switch to ensure it isn't stuck, as covered in the bucket-full-light guide.
- If using a continuous drain hose, confirm it runs continuously downhill to the drain point with no low spots where water can pool and back up.
- Empty the bucket more frequently to check whether the auto-shutoff is triggering at the right level.
- Replace the bucket if it's visibly cracked or no longer seals against the unit's rubber gasket.
