Samsung DMT300RFS Builtin Dishwasher - Answered Questions & Fixed issues

Hello Randy Lowe, There is an EXPECTED INITIAL failure period on new equipment...!! Use your warranty... Brand new = Take it back & get a GOOD ONE. Carnac the Magnificent

might be the moisture sensor nxt to the float. They are both located on the left side where the fill tank connects to the outer side of the tub. It requires removing the unit, turning it upsde down, and opening some framework to get to it. there are instructions on the low-level sensor error page here somewhere.

try to clean bottom filter

Your dishwasher is equipped with a leakage sensor located at the bottom center of the unit underneath. If any water is detected, the sensor shuts down power until the problem is corrected. Check underneath FIRST to make SURE there is no water dribbling from a small leak. Look for telltale residue trails left from evaporated water on the hoses, lines, motors, etc. You can enter diagnostic mode by pressing and holding for 2 seconds the POWER, HEAVY, AND DELICATE BUTTONS. All the l.e.d. s will be lit for 2 seconds, then the software version will be displayed in binary code by the blinking of the WASH, DRY, CLEAN, AND CHILD LOCK l.e.d. s. Next, and this will take some practice, if there are error codes present(sets of blinking lights) you will have to read them to be able to find out where the problem(s) is. •Press the Heavy + Delicate + Power buttons at the same time for two seconds to enter Service Test Mode. •All LEDs are displayed for the first two seconds and then Software version will be indicated in Binary Code using LEDS ....Wash / Dry / Clean/Child Lock •Just like the DMR series you advance through the test next mode by pressing the Normal button . However each test will run by itself (see sequence chart on next page) when test has completed an led will light to indicate test is done and you can then advance to the next test . •Code list and descriptions located on pp#3. Note: Like the DMR series the codes are displayed during operation or test modes and are not stored in memory. Service Test Modes & Codes I hope the following pix are clear enough for you to read, if not I will re-send them! I hope this helps you!

Couple of questions? 1. do you have a water softener? 2. what type of detergent are you using and how much? 3. is the detergent HE rated? To clear out the suds run a cup of white vinegar with 4 liters of cold water and run a rinse cycle. or just put a cup of white vinegar into the dishwasher and run a normal load with NO SOAP... you need to clear the suds from the system to work properly again. the proper detergent to use in most new dishwashers is powder style that is HE rated. and don't use a lot either.

The water-fill SENSOR is what Samsung calls the "Case-Brake Assembly". It's the big transluscent plastic thing on the left-side of the dishwasher. If you need further help, reach me via phone at https://www.6ya.com/expert/ronald_e6b9572cebe3ad27

A Samsung service tech showed me how to fix this one. You can take that float and the white box apart from the dishwasher and once opened, if its like mine, there will be gunk on the float and in the box at the line where it fills with water. This gunk floats in there and prevents the float from swinging and activating the switch. Just clean that gunk out with a toothbrush, I end up doing mine about once every four months, and it should work fine again. This tech said to prevent this, make sure the water is hot at the beginning of the cycle and pre-rinse the dishes-but this doesn't seem to work with mine.

Yeah, those gaskets tend to stretch with age (and hot water). They need to be replaced with new gaskets. If you need further help, reach me via phone at https://www.6ya.com/expert/ronald_e6b9572cebe3ad27

Most manufacturers recommend inlet water temperature of 120 degrees F. During the main wash cycle, the dishwasher will heat that up to between 140? and 165?, depending on what cycle and options are chosen.

your owners manual fault guide will tell you what all blinking lights mean ie,,,how many blinks will tell you where the fault lies

Does it work properly if you advance the switch through the cycles by hand? If yes, the cycles are all fine, the timer motor that drives the timer is bad.

he float on all dishwashers is on bottom, inside, where the water sits. It controls the water shut off point. They are usually not removavble for cleaning. You simply wipe around them and make sure nothing has accumulated or lodged underneath that would stop if from floating freely.

First be sure to disconnect/shut off water and power before beginning. Facing the washer pull it out. On the left side, outside, low, there is the water level sensor. It gets gunked up and trigger lever gets stuck. Clean it out and you will be good to go.

Thank you for the suggestion. I replaced the entire sensor unit and it is working fine now.

The sensor is on the outside of the unit on the left side. slide the unit out of its location, taking care not to pull apart the fresh water hose, drain hose or electrical wiring, the sensor is on the left side, a small clearish plastic box with a rubber hose connected to the bottom, it's probably filled with crud which blocks the plastic float from moving up and down, the float covers and uncovers 2 small electric eyes, carefully remove the box and clean the crud out with an old toothbrush and it should work find, did for mine, good luck ps, try not to soak the 2 small electrical pc boards on the sensor, if they do get wet, dry them well before reinstalling

If I had to guess, I Would think it's a gummed-up water level float chamber. Once you pull it out and clean it the dishwasher should run fine. Pull the entire dishwasher out and lay it down on its side (facing the door, tip it over to your right) There is a little white box. Inside that little box is probably a bunch of sediment and glop, but along with all the glop, there is a wing-shaped float that probably can't move due to the glop. Hold the whole plastic thing under the sink faucet to rinse it out. You will probably have to take off the tub pan in order to pull off the drain hose that's attached to the back of this chamber. But this is far better than having to pay for a service call. After rinsing, put it back in the dishwasher, this should solve the problem.

Its ususally in your drain hose most has a check valve in them now and corn gets in and clogs it wet vac it out pull off your drain hose also check your garbage disposal too if its hooked up to it make sure the holes cleaned and clear.:)

There is an anti-flood valve on the bottom looking like an upside down teacup.

on the bottom of the dishwasher, under the door there is like another panel accross the bottom, pull this off, and you should see the legs for the dishwasher. they might be small one that u need to turn to adjust the height. hope this helps. good luck
