See if voltage is available to the unit. If so,. Replace the power supply within the unit itself.

What is the alarm?
What phase of the cycle are you getting your alarm?

Good Morning Gerald, thank you for your question!

If you are getting an error code E48, it usually means that the board thinks the door PTC (positive temperature coefficient) circuit is closed. This particular part is the wax motor on the door lock. One of the best ways to determine if this is a false error code is to reset the power to the appliance by either unplugging it or flipping off the breaker for about ten minutes. If the error code persists, it would be advisable to contact an experienced appliance repair tech to assist further.

Best regards!

I have the same code and problem...E48:Board thinks the PTC circuit is closed. Any help?
