1. Start the drier normally
2. Before the "EHE" error appears, open the drier door!
3. Because the door was opened during program, "dE" error is shown
4. Close the door and press "start/pause" to continue
5. Program will continue normally; problem fixed!

Did you repair this problem? If yes, how?
Thank you.

Fluff has blocked the drain hole into the water drawer.Try locating the hole and using a small bore plastic tube **** the debris out of the container.

is the dryer getting hot?
if not turn the power off and pull the dryer out and take the back off and push the red button in at the back

There is an access flap below the door on the bottom left.  Open the flap turn blue levers, take plastic cover off (there may be a bit of water there).  Clean the inside.  Problem solved

sounds like your condensin pump is leaking and triggering the over flow micro switch not a job 4 a novice call an engineer good luck
