No control panel lights on Bosch SGV43A03GB/17 diswasher

SOURCE: Bosch dishwasher: won't fill with water

The flood switch is tripped. This is located under the unit. Unplug or flip the breaker to the dishwasher, take off the black kick plate under the door, 2 screws, and you will see the white plastic "pan". The flood switch is located where you can't really see it but it is on the left hand side wall and is made of styrofoam. The best thing to do is to put some rags in the pan, this is not easy because there is little room to put them, and soak-up the water that has filled the pan. Eventually you will get enough water out that the float will deactivate the switch. What you hear "running" when you turn it on is actually the drain pump, it get activated when the flood switch is tripped.

Common problem with these. Control panel (behind all the buttons on the door) has a thyristor in the middle of the PCB for switching the heater element ON/OFF.
After many screws and a bit of fiddling about, get access to back of PCB (print side) to find dry joints. Clean and re-make joints and all should be well.
Caution, this is a high voltage area. Disconnect from mains.
Please see photos.

Hello Richard, Welcome to Fixya ! You've come to the right place. The problem you're experiencing unfortunately is a common one. The water inlet valve has been an issue with B/S/H built ( this includes bosch, thermador, seimens & gaggenau ) dishwasher's going back to the mid 90's. The part to repair it is available at most brick & mortar appliance part centers or you can check out on-line vendors such as repairclinic, apwagner etc. Do a search for part # 1105846 at repairclinic, you'll see what I'm talikng about. By the way it's about $35. Hope that helps move you forward. Let me know if I can assist you further, or need help on how to change it etc. It's relatively easy with Bosch. Thanks for coming to "fixya" for your inquiries and please take a second to rate this answer according to my helpfulness. Goof luck. Macmarkus :)

Hi John, and welcome to Fixya. I don't believe the greasy water sitting in the machine has anything to do with the problem, rather it is likely a by-product of the problem. Based on your post, I would start by first shutting off the breaker. Then removing the kick plate ( access panel at the bottom ) and checking the wiring at the junction box for the dishwasher 120vac supply line. Remove the murret's and visually inspect the wire for "resistance burn" and strip the wires back and install new fastener's if necessary to repair. This is actually quite common to find a wire connector come loose due to improper fastening and once the unit is in use for a while the connections heat & cool, become loose from normal operating vibrations and burn up from all the added heat caused by "resistance". The end result is no power to the controls. Check it out and post back what you find. Thanks for visiting "fixya" and please take a moment to rate the solution/suggestion provided here for you. Good luck. Macmarkus :)
