Maytag dishwasher wont fill

Some dishwashers have a float inside that shuts off the water when it reaches a certain level check to see that the float is not stuck in the high water ( off ) position. Hope this helps.

Water will not fill the dishwasher, it runs but it will not fill with the water inlet plugged?

Hello there

The most common causes of this problem are a defective water inlet valve or a stuck float switch. The float switch sits under the dish racks and sends a shut-off signal to the dishwasher when the water level is high enough. Make sure you only use a Maytag-compatible replacement if you have to change out your dishwasher's float switch or water inlet valve.
Difficulty: Moderate Instructions Things You'll Need:

  • Owner's manual
  • Screwdriver
  • Scrub brush
  • Replacement parts (if necessary)

  1. 1 Shut off power to the dishwasher from the home's circuit breaker box. Remove the lower rack from the inside of the dishwasher.
  2. 2 Check the water inlet valve to see if it clogged or broken. Replace the valve if you notice any problems and test the dishwasher again. If it still does not fill, proceed to Step Three to troubleshoot the float switch.
  3. 3 Consult your owner's manual to find the location of the float assembly. Remove the cover, if applicable to your dishwasher. There may be retaining screws holding the cover in place or it may just snap off.
  4. 4 Hold both sides of the float while you raise and lower it several times. The float should move freely without binding or catching on anything. Disconnect and use a scrub brush to clean the float if you feel any resistance.
  5. 5 Reattach the float and test its movement again. If it is still not moving properly, replace the float.
  6. 6 Replace the lower rack of the dishwasher and turn the breaker switch back on.

Dishwasher runs but no water is flowing to the

Take the kick panel on the bottom front and what you are looking for is an inlet valve its what your water line from under your sink is connected to the dishwasher. You will have an electrical connection on the valve. With a volt meter check to see if you have voltage at the valve when it should be filling with water.If you dont have 110volts then its either a timer or control board problem. If you have voltage when it should be filling with water then it a bad inlet valve.

1999 maytag neptune washer stops after filling up with water

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.

Maytag MDB6650AWW will not fill

My Maytag MDB6650AWW dishwasher would not fill. The lights on the panel were on when I tried the wash cycle. I tested the water valve but no voltage was found during the cycle. I thought it may be the timer/control circuit. I traced the power from the door switch and found no power going to the float switch leg. I found two wires completely cut through (one going to the Water Valve) and three others partially sliced.
