R.S. for Model Number GLTF2910ES0 Washing machine quit working part way through a normal wash cycle. The no spin light was on then machine totally shut off. Checked the error code and it showed an E23 which which is the pump relay. Replaced the control board with a new one. Now when I plug it in, all the lights, door lock, rinse. final spin, and control, flash for 9 times then pause and then repeat. Machine also shows an error code E90. Tried resetting the control panel by holding down the pause/cancel button for 15 seconds but that did not clear the problem. Also unplugged the power for 15 minutes and then plugged it back in but the problem still exists. Any thoughts on what is going on? Is the new board bad?
Answer Hello R.S. The E-90 error code is not a specific code. The error code E-90 is just a group error code. It is indicating a communication error between the two boards in the machine. It does not indicate where the problem is. It could have been a power glitch that caused the E90 error code or a loose connection. One of the control boards could have failed. The manufacturer recommends unplugging the washer for at least 30 minutes to reset the computer. It could be you have a momentary glitch causing some problems. Remove the front panel and on the right side at the bottom, you’ll find the main Circuit board. There is a connector on the harness that needs to be making a tighter contact. Make sure that all the wires that are in contact with the circuit board are firmly connected. The E-23 fault code was indicating that the drain pump relay n the control has failed. Since you have replaced the control, I suspect a bad connection causing your issue. Read More... Answered by AppliancePartsPros.com | Friday, October 12, 2012
