Diagnosis: The locking mechanism between the hose and the lift-away canister is not fully engaged or is obstructed.
Fix:
- Unplug the vacuum.
- Detach the hose completely from the canister.
- Inspect the connection points on both the hose end and the canister port for cracks, debris, or damage.
- Reattach firmly, listening for a distinct click or feeling it lock into place.
- Give it a gentle tug to confirm it's secure.
If that didn't work, the plastic latch or release button on the hose connector may be broken. You will need to order a replacement hose part. The part numbers are in the user's manual.
Heads up: Do not force the connection. Misalignment can break the plastic tabs.
