I just fixed this on mine one minute ago.

Take off the front panel.
You will see a black wire held onto the heat fins by a plastic clip.
This is the thermocouple that measures temperature.
Mine became unplugged from the circuit board and plugging it back in fixed the problem.

The wire goes into a steel box.
take off the screws on the bottom of the box, grab it by the lowed left corner and bend the metal up as far as you can.

The wire plugs into a small white connector on the circuit board.
plug it back in, bend the metal back down, screw it in, replace the cover, and you should be good to go.

Hi! You need to check pump filter. It could be jammed with a coin or hair clip. Now take the machine outside and empty it then lay it on its side and you can access the pump. Take it off, stand up the machine and pour hot water into the soap draw and check water should run out of bottom freely taking any fluff or bits with it. Now take apart the pump and clean it and dry all components before re-assembly. If the machine still doesn?t work then you need to replace the pump. Please do rate this solution as FixYa and revert for further assistance. Thanks Rylee

clean both coils(fins)and drain///use a non-detergent non additive oil(not motor car oil) for fan motor take cover off compressor relay and inspect wires(clean plugs and pins of oxide) you may need a hard start kit if it has a hard time starting you can get a hard start relay kit
