Did not have any tech info when I went and looked at it. Found unit flashing the Over-Level water error, water was touching bottom of lower spray arm.
Nothing I did would stop the error from flashing, unplugged/turned off power/tried Drain Cancel.
Vacuumed water out and that stopped the error then did a Drain/Cancel and pump worked fine.
Tried to run again and it would fill for about 45-50 seconds then immediately go into a pump out then fill again for 45-50 seconds and give the Low-Level water error. Water would be filled to just the top of the fine filter screen below the spray arm which looked like a normal water level to me. Cancel/Drain worked to pump out and cancel the error but it just constantly gave this error when trying any cycle.
Water line was too short to pull dishwasher out while still hooked up to do any more checks and didn't have any tech info so I wrapped it up and will go back with the tech info I have and a longer water line so unit can be pulled out while completely hooked up so water fill system can be check.
Can anyone that knows Samsung tell me what the most likely problem would be in this case? I'm thinking probably a stuck float in the water level sensor case and when the unit fills for 45-50 seconds and doesn't see the low water level then it shuts down after the second attemp, (Would that be correct?).
At one point I thought it was going to work, after the second attempt to fill but then it went into the Over-Level water error and locked up, couldn't clear error or reset until vacuuming the water out of the tub, (I believe it didn't drain fully after the first low-level error that it doesn't report so the second fill hit the over-level sensor before the 45-50 seconds low-level fill should have been sensed).
Any feedback on this would be helpful, I will be going back out on this Monday or Tuesday.
