A thermal fuse looks sort of like an old diode with a colored end.
Go search for help on your specific model. Others may have the same problem. Could be an electrical component fail, or the water valve. Neither would burn the board. See http://www.fixya.com/support/t1725640-bosch_dishwasher_shut_off_timer_says

Hi,the problem with your ps3 is a heat sync failure,it's a common problem with the ps3,however,here is a detailed solution to help you out;
You have to disassemble the ps3 first, (hint) there is a srew were your rubber boot is on the bottom were it stands up remove this srew but you my have to get a star bit with a hole in the center of it. 2. After removing the cover then sides to the screw,lift the cover to remove all visible screws in the second cover. 3. Lift the second cover in a hinged motion to the front of the ps3 be careful not to pull the hidden carbon wire underneath of the cover if done properly you will see the wire when you lift the cover. To release the wire you must lift gently on the black clip holding it and it will release with no problem. 4. You then lift the blue ray drive up and then dissconnect the wires to it. then remove the power pack which is to the left of the blue ray drive remember there are screws holding this down, remove the wires then remove this peice as well, then remove any remaining screws on the mother board cover except the large philip head screws holding the clips that are in a slant. lift the mother board out to reveil the fan on the bottom now remove the srews that are slanted. the fan will then seperat from the mother board. then clean both of the contacts on the mother board and fan with rubbing alcohol. then seperate the metal from the mother board. attention; there will be a watch battery connected to the metal,disconnect from the mother board. gently lift up on the metal to seperate the mother board from the metal. At this point you must be extra careful not to move any of the parts on the mother board remove the rubber peices then cover the heat syncs so they dont melt use a heat gun that can reach a temp. of 350 degrees Cel heat for 15 sec on the three heat sinks with a distance of 1 inch or greater move the heat gun counter clockwise on the sensors. during this time the peice must be level or it will hurt the system. After heated you will then need to let cool for 15 min. then flip the board over and hit the exact same spots in the same steps. at this point your problem is solved. Make sure all the peices of rubber that was on the chips is put back in the right spots too.You then put the metal back on the systems mother board at this point clean the syncs again then apply the artic silver in a thin bead on two heat syncs note not too much and not to little just enough to cover the syncs with a thin coat then connect to the fan. reconnect the fan then put the screws back in that holds them together then reattach the power supply but dont srew it down then remove the srews on the fan moter then remove it plug in your system switch it on stand by then press the sensor pad metal to start the system note this will not hurt your system this causes the artic silver to soder the heat syncs together only do this till you see a orange light come from the board near the fan then shut the system down then reattach the fan and reassemble. Take care
When your model defrost and it's a model HSM25IFTSA the mother board is suspect because the defrost comes from that board. The board part number is located on the rear of your model and behind a panel screwed shut with sheet metal screws. Need to unplug and examine the control board on both sides for burn marks or signs of heat damage. Still you may not see a problem. But you mentioned it defrost too long until things melt and refreeze. The board is part number WR55X10942 and I will place a couple photos below for you to see and what to look for, Sea Breeze
Most times that is a sign of a defrost problem. And because yours has the defrost board made onto the mother board we will need to do some looking around for the problem. Unplug refrigerator and pull away from wall. On back there is a cover over an area that contains the mother board. With power off take the board loose and examine the board for burn marks, sign's of heat or melted away solder connections. If the board looks OK the return it to its place and remove the rear panel in the freezer section. Need you to disconnect one end wire on the defrost element/heater. Check continuity through the heater to make sure there is no burnout. The defrost thermostat is connected to one end of the defrost heater. The contacts are open when the temperature is 50 degrees or higher, so testing it would look bad above 50 degrees. Just look to see if there is any deformity. If defrost thermostat is defective it will not allow the defrost heater to engage or to remain on long enough. Let me know what you fins. Sea Breeze
Sir; I need a recap from you. You talk about one computer or many. We are only to help the final consumer and his advisor. You have gone to the CPU and took it out of socket? Do you have any special heat conducting grease to apply? Don't turn on the computer until you replace the heat transfer compound from the CPU Chip to the heat sink. Your CPU may commit suicide because of you. Anyway, I have one trick that you should check. Bypass the AC switch, not just the button, but bypass the AC, so that the Power Supply has 110 VAC all the time. There is a protection in the low voltage switch button, that, at times it false triggers (or there is a need to shut off because of an overload). When you turn on the computer, stand by with your hand on the plug to pull it, since the idea is to avoid burning up the Power Supply. If this does not work, get back to me but, please, with more descrete information. Thank you for considering our service... My name is Constantin (arzconst)
It is possible to burn out a processor in a matter of seconds without cooling. Please do not attempt to restart the unit, until you replace the colling fan on the processor. If it's not the processor fan/heatsink, you may have lucked out, but don't restart it till you replace the fans.The fan that sits on your cpu is the main concern, if it's one of the others the board should shut down automatically in order to stop this scenario from occuring.
Hello, I solved this problem. I opened the front of the dishwasher (top) and replaced the thermal fuse and then looked at the mother board. The service company had placed two wires back onto the mother-board and were placed in the wrong slot. I moved the wires back to the right location and the dishwasher has since washed to loads without any problems. The service company has been fired.
Thank you for your help,
