What to expect when you experience a Samsung dishwasher won't turn off issue

How is the won't turn off problem fixed?

However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a dishwasher that won't turn off

When the dishwasher won't turn off it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

What to look out for with a dishwasher won't turn off diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

Samsung Dishwasher Flashing Heavy – Won’t Turn Off

The Samsung dishwasher flashing the Heavy light and not turning off indicates that the control detects a drain problem, leak or too much water in the dishwasher.

For Samsung dishwasher models that have the Express 60 cycle, the flashing Heavy light indicates that the control detects too much water in the dishwasher. This is often caused by a drain problem. Follow these troubleshooting tips to fix the problem so the dishwasher will work again:

• Check the kitchen sink drain. Clear a clog in the kitchen sink if it’s not draining.
• Run the garbage disposal if its chamber is full of food and blocking the dishwasher drain path.
• Check the air gap if you have one installed in the dishwasher drain line. Clear the air gap if you find it clogged.
• If you recently installed a new garbage disposal and didn’t remove the knock-out plug for the dishwasher drain hose connection, remove that knock-out plug so the dishwasher will drain properly.
• Check the end of the dishwasher drain hose for grease and/or debris that could be clogging the drain hose. Remove a grease or debris in this area so the dishwasher will drain.

If these basic troubleshooting tips don’t help, schedule dishwasher repair service to have an appliance technician fix your dishwasher.

If you have a Samsung dishwasher without the Express 60 cycle, the flashing Heavy light indicates that the dishwasher’s leak sensor detects moisture. The dishwasher won’t turn off and the drain pump will run.

Check under the dishwasher for a leak. Have a service technician repair the dishwasher if it’s leaking from under the tub.

If you don’t find a leak under the dishwasher, shut off the water supply cut-off valve in case the water inlet valve is leaking. Schedule dishwasher repair service and we’ll send a Sears Home Services technician visit your home to fix the problem.

Why does my Samsung dishwasher not shut off?

When your Samsung dishwasher won’t turn off, problems with the electronic control board or user interface control are likely causing the problem.

Keep in mind that when you cancel the cycle, the drain pump typically runs for a few minutes to pump water out of the dishwasher.

When the dishwasher continues to run constantly even after cancelling the cycle, a stuck relay on the electronic control board could be causing the problem.

To shut the dishwasher off, use the light switch beside your kitchen sink to cut off power to the dishwasher so it stops running.

If your dishwasher doesn’t have that light switch beside the kitchen sink to cut off electric power, unplug the dishwasher power cord or shut off the house circuit breaker to disconnect electrical power.

Reset the Dishwasher Electronic Control Board

Sometimes, resetting the electronic control board will fix a problem with the dishwasher not turning off.

If you already disconnected power as recommended above, leave power off for 2 minutes then restore power.

The electronic control board in the dishwasher will reboot and reset.

If the dishwasher continues to run constantly and won’t turn off after restoring power, you’ll likely need to replace the electronic control board.

Unplug the dishwasher or shut off the house circuit breaker to disconnect electrical power and follow the steps in this DIY video to replace the electronic control board in your dishwasher:

If you’re not confident that you can replace the electronic control board on your own, schedule dishwasher repair service to have a Sears Home Services technician install a new control board.

A Samsung dishwasher that won’t power down can waste water and energy with endless cycles. Stuck door switches or electronic glitches often cause these prolonged runs. Rather than flipping the breaker, arrange a proper fix so you can trust each cycle to end on time.
