Samsung DD31-00005A Dishwasher Drain Pump OEM Part

Since my Samsung Dishwasher would not drain and had a flashing quick light, I removed the racks and both spray wands. Which allowed me to remove the lower screen assembly. This revealed a worn and broken check valve and broken grinder blade. I cleaned the inside of the dishwasher and removed the unit from under the counter. I removed and cleaned the brake assembly ( large transparent plastic section on left side of the dishwasher). I cleaned this for preventive maintenance by taking the float assembly off and flushing it with bleach water solution then rinsing and soaking it with with vinegar while running a thin mechanics wire through the stuck gunk in the vent tube. To get the brake assembly clean I also had to use a garden hose to flush water forward and back but finally I got it clean if the new part wasn’t 100 buck I would have just replaced it because it was the hardest part of the repair. I only found a small section of the check valve inside the dishwasher screen area the rest of it broke off got tangled in the grinder blade breaking it then washed down through the drain pump and was stuck in the hose causing the no drain. I still could not find all of the check valve pieces so I removed the pump assembly thinking I would be able to reinstall the old one. Yet the o ring was swollen and would not go back in place without leaking while I was testing the unit. So I ordered a new drain pump, new grinder blade, new o ring for the water tube for the upper spray wand and upper rack wand. It was also swollen. The new pump is redesigned where the print fits in a grove yet I am sure if I have to remove it one day the print will need to be replaced yet no one offers just the o ring for the old style or new style pump so do not remove the pump unless you plan on replacing it or sourcing a replacement o ring. I could have searched for any debris in the pump housing with a inspection camera found cheap online compared to buying the pump that was still good. The repair and diagnostics were easy many videos found online which will be helpful to you if needed. Once the dishwasher was tested and working we ran some dishwasher cleaner solution we used to use on a monthly basis but forgot about or got to cheap to do. I think if I had kept up with the cleaning the brake assembly would have stayed cleaner but my check valve would have failed faster. With this in mind I plan on replacing my check valve once a year or installing a inline check valve at the garbage disposal to prevent this from happening again

Dishwasher would start then stop after a couple of mins, water not draining. Checked the drain line to the disposal and it was clear. Keypad seemed to respond to changing settings so decided it probably wasn't the control board and ordered a new pump for the drain, which is on the bottom of the dishwasher so you have to pull it out and tip it on its side to replace it. Easy to find right next to where the drain hose connects to the washer (twists off to remove). Put washer back in place and is working fine. $90 (to get it overnight) saved me from having to buy a new dishwasher.

Took the drain pump off and cleared the lines going to and from the pump. Cleared and cleaned the air gap at the top of the sink. On the Samsung DMT300RFS the drain pump twists off. The pump has four tabs that lock it on to the pump body. The tabs fit into tapered slots. The tabs can become brittle from heat over time and will not seat the pump upon replacing. I ordered a new pump that came with a new O ring. I also cleand the fill float chamber on the left side of the unit. The dishwasher works like its new! I also cleaned the drain pan on the inside of the machine. Remove all the screws and take the drain filer screen off and clean underneath. I fill like I saved myself $600.oo dollars.

Went on line did my own diagnostic first replaced the mother board which probably wasnt necessary but I talked to a repair guy on the phone and based on the flashing light it was his recommendation. Dont be intimidated its not rocket science guys. Its really easy to do just mark the plugs when you pull them and plug them into the new board. Dishwasher still woudn't drain, I flushed the drain lines first. Just used the sprayer from my sink and back washed then drained it with a shop vac I finally replaced the drain pump Its all just a few plugs and screws. Im a 61 year old woman if I can do so can you Beats paying a repairman markups for parts my time is free

Took off the old one and replaced it with the new one. Took less than 15 minutes once I had pulled out the D-W.
