How to Troubleshoot & Replace Samsung AP4208383 / DC96-01414A Washer Drain Pump Assembly

I am 68 Years old and I had this PUMP DRAIN part in place and working in around 15 minutes 

Was very easy to remove and replace. Just two clamps for the water hoses, one wire to disconnect and three bolts and the whole pump came out. Easy to get to. I bought the whole assembly since I knew something had jammed in mine and I was afraid that the inside would be damaged so I didn't want to just replace the pump by itself without the housing. 

1. Got the service manual. Removed back panel and removed drain pump completely tore it apart noticed a lot of sand in the impeller portion, cleaned it and reassembled. Power tested the motor seemed ok but did notice browning on case like it overheated. Cleaned sump drain hose no blockage. Put everything back together ran a test load of towels. Same thing not rinsing or draining properly. Ran the quick diagnostic test in service mode, checks pump on and off, water valves on off and dispenser drain, motor drum clockwise and counter,... . spin all good. Put the machine in diagnostic code check - no codes. Hmmm - however when I looked at the description of "dc" code it described the symptoms "unbalance or cabinet bump is detected during final spin, which prevents the drum from spinning over 400 rpm due to unbalance load." Corrective action go to "Wet Clothes" troubleshooting. But it makes sense that the pump is working overtime to drain the tub before it will high spin. Probably their VRT technology. I ordered another pump assembly includes motor and impeller. When I checked the level of the machine it was way off and there was a back foot that had the rubber pad completely ground off. So replaced drain pump assembly, replaced feet with some serious vibration isolators,(from a 600# air compressor), leveled the 4 corners with a spot on bubble level. Ran a huge heavy test load and it was humming quietly and cleaning and spin drying on high like a new machine. YEAH BABY! 

First of all, the last time I tried to get a repairman to help with the washer, no one could come for two weeks, so it was either I fix it or buy a new machine. The docs say to look at kinked hoses. The hoses looked fine from the outside, so I removed the drain pump. This was easy to do in about 20 minutes from the back in my model, but made sure to pump the water from the basket first with my shop vac and keep plenty of towels on hand. The drain pump seemed jammed with debris from a latex backed run in it and thee impeller was a little warped. After cleaning, it seemed OK so I put it back in the machine. Still no drain. So I ordered a new pump from AppliancePartsPros.com, because they are the only ones who had next day delivery. I installed the new pump. Still no drain. So I removed the outside drain hose and found it clogged. I removed it with a metal rod, unfortunately putting small holes in it that I didn't see. After installing the hose, the machine drained and also spurted water all over the floor. It was at night, so I patched the hose with underwater epoxy and duck tape, but I missed a spot and duck taped until it stopped. The next day, I bought an inexpensive hose from a hardware store and installed it. Everything is fine now, and I have extra muscles from moving that machine out from the wall and back several times. 

Replaced the pump 

Replaced rear shocks and installed new pump. Easy part of repair was ordering parts and receiving the parts in one day. 

Replaced the pump assembly. 

Replace pump. 

Replaced pump. 3 screws, two hoses, one electrical connection done . Not bad for a 59 year old woman. Just make sure to cover the edges of metal, it will cut. 

Replaced pump, works new again took like 15-20 minutes
