Mark K Everett , WA January 30, 2017 Appliance: Samsung Dishwasher DMT400RHS/XAA The "heavy" load light was blinking Research indicated that it may be a moisture sensor failure or a leak. It ended up being a leak from the oil seal on the motor shaft. A small piece of plastic made it's way into the system. The hot water softened it enough that it wrapped around the motor shaft, re-hardened, then tore into the shaft seal. I fixed it by replacing the shaft seal, moisture sensor (corrodes when it gets wet), and replaced the sump seal since I had it disassembled.

Pat H West Chester , OH September 10, 2017 Appliance: Samsung Dishwasher DMT800RHS/XAA Weak washing streams from the spray bars dishes do not clean properly All fixed well by changing the sump assembly. Some suggestions: First checked for debris/clogs inside the sump (take cover off) as well as flapper valve (could loose water pressure through drain pump). All OK so indicated weak main pump motor. Motor itself is about $125 and the entire sump assembly which includes the motor is only $30 more so don't bother just changing a motor as better value (and easier) to change entire sump assy. If you have a Samsung and want to follow the online video, there are some things to do differently. 1st - when installing the new capacitor, don't connect the wires as they come off for the sump installation. 2nd - Don't reattach the plastic bottom frame after installing the capacitor as you have to leave it loose and pulled forward to get better access to the 3 clamps holding the sump assy. Biggest pains are disconnecting the unit to remove it from under cabinet to do the work. All else is easy, just takes time. Suggest you watch the online video and then making the changes noted above so it goes easier. I also changed the Sump seal. At $48 it is an extra cost but well worth eliminating the risk of using the old seal.
