I have a neptune front loader washing machine. It fills up with water and then just stops. We checked the belt and the door pin and those are fine. Any suggestions on what this could be? thanks!
There are a couple of common causes for a problem like this. First is a bad door lock assembly that also damages the machine control board (in the control panel). If this is the case the R11 resistor on the machine control board will be burnt.
Maytag has identified seven resistors that relate to specific components that need to be checked or replaced if the resistor is damaged. Listed here are the resistor identification, the circuit involved, and the recommendation:
R9 / pressure switch / check for loose connections or high resistance on switch contacts; replace pressure switch if necessary.
R11 / door lock wax motor / replace door lock mechanism and machine control board.
R51 / hot water valve solenoid / replace water valve and machine control board.
R52 / timer motor / check for loose relay terminal connections and replace machine control board.
R53 / cold water valve solenoid / replace water valve and machine control board.
R143 / (-) 24 Volt DC / contact was made between neutral and the 24 Volt DC circuit.
R162 / electrical buffer circuit / wire harness and machine control board.
Another common issue is a slow water fill fault. If the washer does not fill within a certain time the control will stop on a fault. Usually when this happens the START button can be pushed to continue the cycle.
Washing machines that won't fill or fill slowly often have a restriction in the incoming water supply -- usually in the screens of the inlet hose washers or the water inlet valve itself. Remove the hoses to inspect this condition. If the water inlet valve screens are plugged, replace the water inlet valve.

You have tried both a Hot fill and a Cold fill and still no water flow?
You could try going into Service Mode and turn on the water inlet valves with console commands. See page 16 of the Service Manual and see if you can turn the water inlet valves one at a time and get water to flow into the machine. Getting into Service Mode is easy to do
The Service Manual for reference. Sears Parts Direct for reference.
If still no water flow it would be time to check 120VAC on the water valve solenoids when you command them on in Service Mode. If no 120VAC present then we might have a Stuck open High level pressure switch which would disconnect 120VAC to the Control Board relays that operate to switch 120VAC to the Hot/Cold solenoid valves.
How do you feel about troubleshooting? Do you have a DVM? I have the schematic in PDF format if you need. Let me know if you want to DIY the fix......Rich
