My Bosch SHU5306 had the burnt solder joint on the circuit board. I soldered it and the dishwasher worked fine, but only for about three weeks. Now it runs down to "1" and doesn't finish the cycle again. I checked my solder on the circuit board and it's still fine. I ran the test and it came up with a "2" pointing to a heater problem now. Does anyone have any ideas? Has anyone else that has soldered the circuit board also had a further failure?

I have had the same experience with a SHI6802/U06. That is dishwasher would not countdown, because it could not come up to temperature. I took repaired the control module by soldering the joint that supplies current to the heater. The dishwasher has worked great for about one month. Now it hang on the counter because it will not come up to temperature. I took the control unit apart and my repaired solder joint is in tact and no sign of burned wiring or any other component failure. When I run the diagnostics, I get the same error code as I did before I fixed the solder joint which is "1" Aqua Sensor.
Anyone have any thoughts, please pass them on.
