Hi @steve47649
It could be there's a problem with the water level pressure sensor or the water pressure hose that connects to it from the bottom of the tub.
As the water enters the tub it also rises in the hose and this increases the air pressure on the pressure sensor that is connected to the other end of the hose. When the water reaches the level selected on the control panel i.e. amount of air pressure detected = desired water level, the water inlet solenoid valve is turned off and the washer starts the wash cycle.
Here's the tech sheet for the washer.
Enter the diagnostic test mode as described in the sheet - see p.2 Activating Service Mode and check if any error codes are being displayed. The error codes and their meanings are shown on p.8 → p.10.
Check if you get an F3 E2 Pressure System Fault code. On p.8 it shows what to check.
if you don't get any error code perform Test #6 Water level anyway see p.18.
Hopefully the pressure hose (part #WP353244) is the problem i.e. pinched, kinked, plugged, or leaking air and it is not the transducer (pressure sensor) which is located on the control board (part #W11419171) as you would have to replace the control board and it isn't cheap.
Note: Your control board may have part #W11266006 printed/labelled on it but it is no longer available and has been replaced by the board with the part number I listed above.
Here's a none too steady video that shows how to access the control board in Maytag top load washers (don't know if it is your model but it looks like it or a similar one) where the pressure hose can be seen connected to the board. Stop the video at 1:34 minutes to see the clear plastic tube connected the board.
If either part is faulty and needs to be replaced, search online for the part number only to find suppliers that suit you best.
