Samsung manufactures several varieties of dishwashers. In most cases, however, they all function in the same manner. Water comes into the machine through a water supply line, the heating coil heats the water to create steam and then the water drains from the machine through a flexible drain line. If any of these tasks fail, the Samsung dishwasher will fail to clean your dishes. When this happens, troubleshooting is in order.
Turn on the dishwasher and start to run a normal cycle.
Stop the machine after approximately five minutes by pulling the release handle. The safety switch will automatically stop the heating process. Remain cautious, however, because the dishwasher could already start creating steam.
Inspect the basin or bottom pan of the dishwasher and inspect the dishes in the washer for moisture. If working properly, the basin of the dishwasher should have at least 1 inch of standing water and the dishes should have a moderate amount of condensation on them. If this is the case, the water inlet valve works properly. If the dishwasher is dry inside, move to the next step.
Turn off the water supply to the dishwasher. In most cases, the shut-off valve is under the sink.
Pull the access panel off the front bottom of the dishwasher by removing the screws that hold the panel in place.
Loosen the compression coupler on the copper pipe that connects to the inlet-valve. The inlet valve is on the left side of dishwasher behind the access panel. Use a wrench to loosen the compression valve.
Place a container under the copper line and then slowly turn on the shut-off valve. If water comes out of the water line and into the container, your water line works properly and the inlet valve on the dishwasher is defective. If water does not come out of the line, the shut-off valve is defective.
Turn off the breaker that controls the dishwasher. Most Samsung dishwashers use a direct wire connection so you must disconnect the wiring to remove power at the dishwasher. Turning off the power at the breaker accomplishes the same goal with a lot less work.
Remove the access panel in the front of the dishwasher by removing the screws that hold it in place. Once you remove the access panel, locate the terminal wires for the heating element. You can look at the element in the bottom pan of the dishwasher and see where the ends of the element go through into the bottom of the pan.
Disconnect the wire connectors from the terminals by pulling on the connectors.
Place your multimeter on "OHM" and touch the leads on the multimeter against terminals on each end of the element. If the multimeter moves off zero, the element works properly and the issue is with the internal circuitry. If the multimeter readout remains zero, however, the element is 100-percent resistant. This makes the element defective.
