When I push "Start" on my Maytag Neptune front load combo, it lights up, the door locks, then it starts filling and after few secs it cuts off, what can I do?

If this is a combination washer dryer (model number starts with MLE). First disconnect the power to the unit and locate the main control board located on the top right hand corner. You can remove the two 5/16 screws holding the top of the front panel and move the front panel forward to remove the other two 5/16 screws holding the front of the top panel. Once these are removed there is one more 5/16 screw holding the board in place, remove the screw. Now lift the top panel and pull out the board with the wire harness. Search for the resistor R11 on the board (it's towards the middle). If this resistor is burnt, replace the main board and the wax motor located inside the latch mechanism ( it will have a red/burgundy color plunger which will be replaced with a wax motor with a black plunger). If R11 is intact, look closely at the latch system, and replace it if needed.

The pump is accessable through the back panel. Simply remove two screws and the cover. There are blurbs available on fixya as to what do do from there. Good luck.

If you did the repair yourself, double then triple check the wiring. Find a repair manual and start hunting.

If you had the work done, call the shop and tell them what happened. Most likely, a tech will do a house call for free if you are persistent.
