Kenneth K Freeport , PA June 16, 2014 Appliance: Model DMT300 Error code on samaung dmt300 dish washer (low level water error) Researched problem on internet, problem code indicated a dirty level sensor, advice was to purchase a new one. I ordered one from Appliance Parts Pros over the internet,, it,, amazingly arrived the next day. I installed the part, ran a couple of loads, it now runs fine...I saved the old one will clean it,,all gummed up with crud and keep it for a spare. Original lasted about 2.5 years.
