Control Board

Control Board

Anthony from IL

Bosch Diswasher, model SH3AR75UC/23, would not power on

Phillips screw driver, flat head screwdriver, and patience

Bosch dishwasher stopped powering on. Power is hard wired. Checked wires leading to dishwasher and was getting 120v. Checked wires coming out the other side to the power control board and was getting 120v. tested wires after the board, and got nothing. This told me the power board was the issue. To replace power control board, i shut the breaker off for the dishwasher, removed the two screws that held dishwasher to counter top. Then under the sink, turned the water supply off, loosened the water hose and the return hose as room would be needed to pull the dishwasher fully out from under the counter top. The dishwasher has to come completely out to change this board. The feet of the dishwasher were retracted all the way and the counter top had to be loosed to get the dishwasher out. Once fully out, i had access to control board. Unplugged the power cord from the back of the board, took pictures of the plugs and the location they were plugged in on the current board and then removed. There are plastic guides for the cables that plug into the board. These have to be removed from old board and put on the new board. A flat head screwdriver will pop these plastic guides off of the old control board. I then plugged everything into the new board and put it all back together and put dishwasher back under counter top. The dishwasher powered up, threw a couple of errors, one of them being the water is low then all the lights came on and i shut the dishwasher off. When i powered it back on, it showed 2:10 on the display which is the time that a normal wash takes. I tested with a load of dishes and all worked perfectly. Replacing the board itself is Easy. It took me almost 2 hours because of the time it took to get the dishwasher out from under counter top. My hardwood floors sit higher than the dishwasher thus causing the time consumption.
