There are a few things that could be going on. One possibility is that the water level in the tank is too high and it’s preventing the machine from starting up properly. If this is the case, you can try emptying the tank and then restarting the dehumidifier.
Another possibility is that there’s something blocking the water drainage pipe. You can check this by removing the front panel of your machine and inspecting the drainage pipe to make sure there are no obstructions. If you do find an obstruction, remove it and then restart your dehumidifier.
