I have Maytag stackable LSE7806ACE and the water continues to fill and never stops filling during the cycle. Also the dryer runs but there is no heat. Help!

There is a fill switch connected to the tub w/ a tube. Verify the tube isn't plugged. Otherwise, the switch is likely the culprit.

Check the 220V supply. If you have fuses, are both "legs" good? If it is a breaker, turn it off, then on.

Look at the heating element (power off). Is it broken? Check continuity w/ ohmmeter. Check the low limit thermostat, it should be "shorted" at room temperature.
