Note: This solution is intended only for asker qualityisc as per Live Chat session discussion. Error code reads E47 which means the Control board thinks the PTC circuit (wax motor) is open.
Unplug the machine then remove the spring-loaded wire loop that holds in place the front of the bellows over the lip of the door opening in the front panel.
Using needle nose pliers, start where the spring and wire are connected at the bottom of the bellows and pull the wire out of the groove of the bellows then pull the bellows off of the lip of the front panel.
Remove the screws
securing the door lock and switch assembly to the front panel. Once the
screws are removed, lift the door lock and switch assembly then pull it
away from the front panel.
Take the door lock and switch assembly
out of the machine and disconnect the electrical connections.
Measure the resistance of the wax motor. The
normal resistance is around 1500 ohms. Shorted or open
circuit wax motor means the door lock and switch assembly needs to be
Simply replace the door lock and switch assembly
(part #131763202) if the wax motor reads shorted or open to address the issue.
But if the wax motor resistance is normal, check the continuity of the door lock and switch assembly wire harness, particularly the wax motor wire harness. Start with the continuity of the red/black wire of the wax motor harness to each of the red/black wires of the door lock and switch assembly harness. They should all have continuity; otherwise, replace the harness.
Remove the top panel to access the control board if further continuity test is necessary or if the red/black wire of the wax motor harness has continuity with the all other red/black wires of the door lock and switch assembly harness.
Remove the screws attaching the top panel to the rear of the cabinet then lift the panel off. The console can be removed from the cabinet to completely access the control board connections, particularly the door lock and switch assembly harness connections. Check the continuity of the red/black wires at the door lock and switch assembly to the red/black wire of the harness connected to connector J2
on the control board.
The problem is in the control board if the wax motor is good and the door lock and switch assembly wire harness has all the necessary continuity. The only viable solution, should that be the case, is the replacement of the control board.
