No, a dehumidifier takes water out of the air where it's placed. If it's very humid in the air, you should have a tank full of water after a few hours.

Are you much of a handyman? Most folks set their dehumidifier on a counter or elevated and run the exhaust tubing right into a sink or toilet. You could collect the water to flush a toilet or water the grass if you are handy. I've never seen anyone connect directly to a drain though.

There's usually a piece or tubing that hangs down into the tank and you need to pull your tank past this when removing it to drain your dehumidifier. Are you lifting from the top or bottom? Try the opposite of what you are doing. Sorry I don't know your model specifically, but often there's an outlet or cap at the bottom of the tank that can have a plastic piece of aquarium type tubing hooked to it. This way if you can elevate the whole dehumidifier, say on a counter, the water can just drain into a sink or if you're a real conserver into a storage tank to use to flush your toilet or water your grass.

No power, no error code equals a dead dehumidifier. Far too costly to repair. I recommend putting those repair bucks towards a replacement dehumidifier. Frigidaire units are highly rated.

I have a Comfortaire BHD501 dehumidifier. A couple weeks ago I noticed ice building up on top of the unit,so I unplugged it to defrost. I plugged it back in and it worked until I noticed the "CH" "01" code. It would run a few seconds then shut off with that code showing. I took off the front of the unit and noticed rust on some of the metal parts. Then I took the cover off the circuit board for the front read out. I noticed corrosion on some of the solder points. When I looked closer at the plastic cover for the circuit board I noticed a small burn mark. The water from the melting ice must have run behind the cover and shorted out the circuitboard. At this point I don't know if new boards are available.

What is your humidistat set at? Could you be trying to get to too low a humidity? Try to determine what the humidity is and set the stat just below that. In that way, once it reaches the setpoint, it will cycle off, allowing the coils to warm up.
If that works, lower the setting a bit more & see results.
Write back.
