Question about Bosch SHU9915UC Dishwasher
Bosch shx43a09uc/46 will not heat water& runs over three hours before ending a normal cycle. The other three wash programs have the same problem. Where is the temp. control modual and the heater on this model?
Found wire diagram next to left front leveling screw with instructions for checking out the no-heat problem. Solved by finding a overheated solder joint on the control printed circuit board which caused loss of signal from the control to the heater.
Use caution when removing the control from the door position as the plastic snap locks break quit easily.
Obviously this solder joint had developed enough heat to melt the solder and finally was destroyed by electrical arcing; if this is true and the excessive heat continues, resoldering may not be the final answer to the problem but may require a new circuit board design.
