The dishwasher thermal fuse protects against overheating appliances and causing fires by stopping power from flowing through the machine if the fuse blows. It is dangerous for you if the fuse blows!

To check whether the thermal fuse needs to be replaced or not, insert a multimeter between two points of contact on the device. There should be continuity between two points (usually metal) and electricity should complete the circuit when touched by both places.

Water supply issue

The Samsung dishwasher might not fill with water if the hose connecting your dishwasher to the faucet is disconnected or blocked. It might also have been improperly tightened. To check for these problems, turn off the power and unplug your appliance before looking for foreign objects under it.

A kinked or clogged hose can prevent your dishwasher from starting properly. If possible, turn off the local water valve for five minutes before running the dishwasher so that excess water can drain away. Please open the local water valve before using the dishwasher.

The water inlet valve may be defective and the machine will not start when turned on. You should seek expert aid before replacing the part as required if needed.

The child lock is enabled

To deactivate a Samsung dishwasher’s child lock feature, press and hold both buttons for three seconds until you hear a beep. You can also unlock it manually by entering your four-digit code on the keypad.

The dishwasher is washing the incorrect setting

Your dishwasher may be experiencing a hung cycle problem if the lights are flashing or it is stopped halfway through a cycle and cannot reset properly. Dishwashers that get stuck in a wash cycle cannot start a new cycle, so if your dishwasher is stalled, it’s time to give it a once-over.

Try pressing the button and turning it off and on again; this should restart things.

Make sure that you haven’t accidentally selected the wrong option. Samsung dishwashers function as follows:

To prevent accidental adjustments, select this option to lock the control panel buttons. When you select it again, the controls will be available for normal use.

This dishwasher has a child lock feature that prevents children from accidentally turning it on while it is running.

You can set up sleep mode so that your appliance will not start until there is an active water source connected or turned on at all times (a standard faucet).

DELAY Start (DELAY): This setting will start the dishwasher at a specific time.

Check both the door latch and the door switch

In some carpentry tasks, you have to check the door latch and the door switch.

The dishwasher’s latch ensures that the dishwasher door shuts securely. The dishwasher’s switch detects whether it is closed and prevents it from operating if it is not (this prevents flooding, etc.). If your latch fails, you must replace it with a new one.

The dishwasher’s door switch keeps it from operating if the door is open. If the switch is defective, it might stop working even when you close and lock the door.

To determine if a malfunction in the part is to blame for your problem, use a multimeter to check for continuity on the switch that prevents the machine from operating during most wash cycles. If there is no continuity, replace the switch.

The timer is broken

The electronic control board of a Samsung dishwasher determines the time of day and duration of each wash cycle. The automatic switching between cycles based on when you want your dishes clean depends on timers.

Your dishwasher may not work if the timer has gone out. You won’t be able to tell if the timer has malfunctioned because they don’t make any noise and continue working on their own. It is possible that this could happen due to faulty wiring in the appliance or connection problems in other parts of it.

The motor drivers are faulty

If your dishwasher’s motor is broken, your dishes will not be cleaned. The drive motor sends rotational motion to a spinning rotor inside, which forces dirty wash water onto all of your silverware and plates before sending them down through the drain hole at the bottom for full rinse cycles.

Please call an appliance repair service as soon as possible if anything goes wrong with this complicated machine!
