Hi, my name is Aaron and I am new to the forum and was trying to seek some help with a problem we're facing with our Samsung dishwasher. The model # is DMT800RHW. Firstly, this is in a rental house so I have not looked at the dishwasher in person yet. My tenant says the dishwasher will run for hours, which is not normal behavior. She says the water DOES get hot and the soap dispenser door does not open. So it's almost as if the cycle is stuck in some pre-rinse mode. I researched other threads here and some ideas centered on the heater element or heater relay being bad but since the water gets hot that does not seem to be the issue here. My gut feeling is the main board has an issue, as we had the board replaced once under warranty already. I am not sure I want to spend money to get it fixed if that's the case.
Any ideas why this d/w would run non-stop for so long? I appreciate any ideas you can share!
I was doing more research and apparently the "sanitize" option can be hours long, per Samsung's website. So maybe the tenant has the wrong setting chosen. Time to pay them a visit.
