Samsung dishwasher dmt 300rfb wont drain and is humming

No a noise filter is a different kettle of fish. That stops electrical interference noise from affecting your television, radios and electrical devices.

The most likely source of the hum is the start capacitor on the motor, or the motor itself.

This has a different idea

Humming or Grinding If your Samsung dishwasher makes noise when starting that sounds like a low hum, it's part of normal function. The motor makes this sound as it operates throughout the wash cycle. However, a dishwasher making loud humming noise or grinding sounds could mean that debris is caught in the drain pump.

Samsung Dishwasher Making Noise? Follow These Tips

This says the drain pump, but the drain pump only runs to empty out so it wouldn't do it all the time.

How old is your dishwasher? How long has it been since it has been serviced?

I'll bet that Delicate light is flashing, which is actually indicating an error. You didn't mention your model number, but in most Samsung dishwashers I'm familiar with, that light indicates a Drain Error. You may have something hard caught in the impeller of your drain pump, or you might have a bad ECS sensor. In any case, it's time to call a dishwasher repair technician. For Samsung dishwashers, I recommend calling Sears Service (1-800-4MY-HOME or 1-800-469-4663).

What 2 cycle lights? Samsung dishwashers indicate problems and errors by making different lights light up and/or flash. We would need to know the model number too.

Heating Element

If lights are flashing on the control panel, the heating element might have burned out. The heating element heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element can be checked for continuity with an Ohm meter.

Check Fault Codes

If the display lights are flashing and there is an error code in the display window, check the wiring diagram and tech sheet in the dishwasher that will provide information on the fault.

Drain Pump

If lights are flashing on the control panel, the drain pump might not be working properly. For two-wire drain pump motors check them for continuity using an Ohm meter. If it's defective You'll need to replace it. Drain pumps are not repairable.

Touchpad and Control Panel

If the lights are flashing on the display the entire touchpad and control panel assembly might be defective. If the display works but the dishwasher functions are all out of synch, or some of the buttons don't respond properly the entire touchpad and control panel might need to be replaced.

Touchpad

If the display lights are flickering for no reason, the touchpad might need to be replaced. Sometimes when the touchpad is defective the display lights are flashing randomly.

Hi,

Some SHX46 washers have 4 wash cycle buttons and others have 5. The button on the left side on top of the door is the start/stop button regardless of how many wash cycle buttons you have.

If you have 5 cycle buttons, reading from left to right they will be as follows.

1. Top Rack Only / Sanitize
2. Power Scrub Plus - (Long wash for heavy soil)
3. Regular Wash - (Economy wash for light to medium soil)
4. Delicate Wash - (Shorter wash at a lower temperature for delicate items)
5. Rinse & Hold.

These buttons are also used for cancelling a wash cycle. Hold down buttons 2 and 4 (Power Scrub Plus and Delicate) at the same time to cancel a wash cycle and drain the water out.

If your washer does have 4 buttons, it means you don't have a Top Rack / Sanitize cycle, in which case the button configuration - from left to right - will be:

1. Power Scrub Plus - (Long wash for heavy soil)
2. Regular Wash - (Economy wash for light to medium soil)
3. Delicate Wash - (Shorter wash at a lower temperature for delicate items)
4. Rinse & Hold.

With this button configuration, the cancel cycle buttons are 1 and 3.

I hope this solves your problem. If you need any additional information, please post back.

Hi,

Some SHX46A washers have 4 cycles and others have 5 cycles.

I'm fairly sure your model has the hidden buttons on the top of the door and you stated you have five-cycle buttons, in which case they will be as follows.

1. Top Rack only cycle or Sanitize
2. Power Scrub Plus
3. Regular Wash
4. Delicate Wash
5. Rinse and Hold.

These buttons are also used for cancelling a wash cycle. Hold down "Power Scrub Plus" and "Delicate" at the same time to cancel a cycle and drain the water out.

If your washer does have 4 buttons, it means you don't have a Top Rack / Sanitize cycle, in which case the button configuration (from left to right) will be:

1. Power Scrub Plus
2. Regular Wash
3. Delicate Wash
4. Rinse and Hold.

I hope this solves your problem. If you need any additional information, please post back.

Do the diagnostic test:
SHU 53 MODELS

To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show “88′ when REGULAR WASH button is pressed and “8h” when Delay Start button is pressed.
To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor (“Sensotronic”) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code “4′ and unit will continually fill and drain where testing won’t be completed. If flow switch (e5) has failed (opened), display will show “0′, water won’t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code “8′ immediately and testing will end shortly after water has started circulating.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

if it hums when you are in the wash phase then something is jamming the wash impeller like broken glass tooth pick found a necklace in one one time i think replacing the control board fixed the other problems on most washers the drain pump is separate from the wash motor haven't worked on bosch so not sure take off the lower spray arm and go down till you get to the impeller then do what you have to do clear it or replace wash motor
