Apr 23, 2015 - The dryer's heating element works and the motor runs smoothly, But it... and then running the dryer with nothing inside for a few minutes-if it ...

Family error code E50 means a problem with the washing motor. Family error code E70 means a problem with the NTC sensor. In my experience, E50 is most common fault in worn carbon brushes. But in any case family error code E50 is shown to the customer. In service mode could be: E51,52,53 and 54. The same applies to family E70 error code that will be displayed in service mode as error code E71 or E74.
E50 error code could be: motor winding, power board, tachymetric generator, motor relay on power board, wiring between motor and power board and wiring between tachymetric generator and electronic.
E70 error code could be: faulty NTC sensor, wrong position of NTC sensor or to much limescale on it and finaly wiring between NTC and electronic.

Hello Friend, this is Z. I appreciate your post!

To get the error code your dryer may be experiencing, attempt the following:

Wake your dryer by pressing any button except for CANCEL.

Press and hold the "CANCEL" and "START PAUSE" buttons simultaneously for 6 seconds to show the error recorder code your dryer may have. The error code normally appears in the display as an E followed by two numbers.

If your dryer shoes, E00 it indicates no failure code was detected.

I ask that you please follow up with a comment on the post, at your convenience, to advise if you receive an error and if further troubleshooting is needed.

Thank you!

Need to put into self diagnostic mode and test the components. You can find the tech repair sheet in the machines that will tell you both what the error code is, how to test it, and how to replace it.

An imbalance during the spin cycle has occurred. It's possible that the appliance has been overloaded, or the load is causing the drum to be unbalanced.
If the machine has been used repeatedly in a row, which can cause the motor to be overloaded, leave it to cool down for approx. 30 min. and then try again.
If the problem continues to occur, there is a problem with the motor. This has to be repaired by a Service Engineer.

E50 code is for a motor issue or main PCB fault on the motor output side (also called E51 when the triac that is on the main control board normally shorts out due to a faulty motor).

If motor runs continuously with power applied, check for short circuit across motor relay (RL2), or L1 applied to motor relay output (J3-1) with cycle stopped. If motor does not start when Start key is pressed, check for open circuit between L1 and motor relay connection (J3-2). If no wiring problems found, replace Main Control Board.

code E50 is an motor error. try exchanging the motor?

i would have to guess that its a problem with the control board. if it were the user interface it would most likely fail right away and not after a few minutes.
either one are expensive, but the board should cost about 120 bucks
