The most common reason for leakage from a dehumidifier is that the water tank has been taken out of the machine before all the water in the machine has drained into the water tank. If the water tank is taken out too soon, while the user is emptying it, water continues to drain into the base of the machine and eventually leaks through the casing onto the floor. Always wait at least 5 minutes after the machine has stopped before removing the tank for emptying.
Another source of leakage can be damage to the water tank itself. If a water tank is dropped, distorted or compressed, the plastic can develop cracks. While the crack may be hard to see, it can result in a slow leak into the base of the machine that ends up on the floor under the machine. To test a water tank for leaks, empty it and dry the outside of the tank thoroughly. Dry an area for the tank to sit, e.g. a bath, shower or laundry tub. Place some dry paper towel under where you are going to sit the tank for the test. Fill the water tank two thirds full, being careful not to get any water on the outside of the tank. Sit partially filled water tank on the paper towel and leave for at least 4 hours. Any leak will become evident after this time.
In some machines a dirty filter can create a vacuum within the machine and when this happens water is sucked to the back of the machine and by-passes the water tank. Again, this results in water gathering in the base of the machine and leaking onto the floor. To avoid this problem, make sure that you regularly clean the filters on you machine.
Always ensure that your machine is sitting on a stable, level and even surface. Most machines will leak if they are sitting out of level or if they can rock from side to side while they are operating.
Whenever you are going to move a machine, turn it off and make sure that you wait 5 minutes for all the water to drain into the water tank. Empty the water tank and then replace it in the machine. While moving the machine, always make sure that it is vertical while being carried or wheeled and don’t make sudden jerky movements. This will ensure that any water that is sitting in reservoirs higher up in the machine does not spill into the base of the machine.
Always make sure that the float within the water tank is free to move up and down through its full/normal range of movement. The purpose of the float is to switch the dehumidifier off when the water tank is full. On the rare occasion that a float gets stuck in the ‘empty’ position, the dehumidifier can keep running even when the tank is full and this results in overflow and leakage. Every time that you put the water tank back into your machine, do a quick check to make sure that the float is free to move.
When using the Continuous Drainage Hose make sure that the hose is attached well, is undamaged and is always sloping down from the attachment point on your machine.
If you have the Supreme All-seasons 50 L machine, make sure that you connect the Automatic Pump-out hose as described in the Instruction manual at the bottom of page 8 and make sure that the hose is undamaged and free from kinks and obstructions.
