The E7 error code on a Samsung dishwasher indicates a water heating error. The dishwasher is unable to heat the water to the correct temperature. This can be caused by a variety of factors, including a faulty heating element, a faulty thermostat, or a problem with the dishwasher's water supply.

1. Check for clogs in the dishwasher’s drain

  1. Turn off the dishwasher at the main switch.
  2. Open the dishwasher’s door.
  3. Look for any objects that may be blocking the dishwasher’s drain.
  4. If you see anything blocking the drain, use a plunger to clear the obstruction.
  5. Close the dishwasher’s door and turn on the dishwasher.
  6. Wait a few minutes for the dishwasher to finish washing the dishes.
  7. Check the dishwasher’s drain to see if the problem has been fixed.

2. Clean the dishwasher’s filters

1.Turn off the dishwasher at the main circuit breaker. 2.Remove the dishwasher filters by gently prying them off of the dishwasher’s housing with a flat-head screwdriver. 3.Place the filters in a large bowl of hot water and soak for 10 minutes. 4.Rinse the filters well with cold water and place them back on the dishwasher housing. 5.Replace the dishwasher’s filters and turn on the dishwasher. 6.If the dishwasher still does not work, check the filters for obstructions and replace them if necessary.

3. Clean the dishwasher’s interior

The first step is to remove the dishwasher’s racks. Next, unscrew and remove the bottom panel. Finally, use a vacuum cleaner to remove the built-up dirt, food residue, and soap scum from the interior of the dishwasher.

If the answers above didn't work then you should also try:

  1. Check the dishwasher’s water supply.
  2. Check the dishwasher’s electrical connections.
  3. Call a qualified technician.
