Received an E1 error on my Samsung DW and was not able to make it through a cycle. After some research, determined that it was probably the thermistor. With the option of buying a new DW or having a service company come out and fix the problem for $300+, I decided to give this site a shot. Glad I did. Replaced the thermistor and the problem has been solved so far (only ran 2 twice since replacing). The videos are extremely helpful and made it easy for me to address the issue.
