I have been through the initial phase of the very same problem. However, after reading the many other posts (and attached documents) on this forum I have only replaced the thermistor. For me troubleshooting (partly with onboard diagnostic modes) showed case brake, overfill sensor, and main PCB were all fine. The supposedly failed thermistor showed a 48 Kohm (via three multi-meters) reading at room temperature which did not make sense for a 3.3Kohm (description of the part confirmed by Samsung) thermistor. First cycle with a new thermistor did complete but again after reading the posts, many times a problem re-occurs. My concern regarding re-occurrence is that out of the three new thermistors (from two suppliers) I ended up with (asked for replacements because assumed they were defective) all reported 44-46 Kohms instead of the expected 3.3Kohms at room temperature. I took the lowest resistance 44.6 for my replacement part. However, something is very wrong with this part. Either Samsung made a change on the fly to a 45Kohm thermistor, all of the four parts really are defective, or the thermistor functions unlike any I have seen before (i.e. rated resistance s a not given near room temp.). I wonder if people have been checking the new thermistors when they replace. Have you?
