Brand: Bosch Model Number: she3arf2uc/22 Main Symptom: Erratic cycle time and throwing three different errors. What happens & when: Three minutes to auto cycle it throws an E15 error but continues working. The timer jumps from 2:20 to 1:00 and then it will jump back to 2:10. It will keep running and throw E17 and E5 errors.
Since it’s jumping all over the place with errors and time, I take it that I have a bigger issue with a computer or something?
Is there a service manual I can download?
Also the front control panel of this unit cracked about 3 months into ownership. I found online that a lot of people had the same issue, but I could not get Bosch to give me a new plastic panel and Lowe’s service warranty wouldn’t repair it either. So I’m not sure if this worth repairing if I need a more expensive part like a controller / computer.
Error Code (if any): E5, E15, E17
Parts or tests already tried: This model is before the tray in the bottom that collects water, so I am not sure where the switch is for the E15, but that may be a moot point because of its erratic behavior.

From what I can see, the error E5 relates to the water switch seeing a continuous water flow, the error E15 indicates an overfill situation has occurred, and the error E17 indicates a flow rate is too high. Is the dishwasher only 3 months old and how long has this failure been occurring for? Also, does it sound like the water valve operates for more than 2 minutes total or does it seem like the water level gets to be more than an inch above the sump before the failure shows up? All of these errors point to a power module failure, but it is worth verifying that everything else involved is working properly.
The sump would be the center section of the dishwasher where the filters set into place. Primarily, we are looking to see if water gets above the filter and by how much. Timing the valve would be necessary to identify if it is receiving voltage for more than 2 minutes total. Generally, just listening for it to hum will indicate if it is receiving voltage. However, if water continues to fill while the valve is not humming from voltage traveling through, it could indicate a valve leaking by.
