I have a Bosch dishwasher, model # SHU9915UC. It is approxametly 8 years old and has been operating perfectly and we run it about 3-4 times per week. After turning it on this morning... about 1/3 of the way through the cycle, I smelled a strong burning smell. It smelled like it could be electrical in nature. However, it was still operating okay, although I did turn it off immediately.
Thanks in advance for any input!

Could be the heater relay connections on PCB - they overheat causing poor connection with circuit board -will fail and machine won' t heat up. Board situated in door and is not easy to remove patience not force required! You have to find all the clips to release it -assumming youv'e managed to get thefacia off.
