How to Troubleshoot & Replace Bosch AP2802870 / 00266746 Control Module

Replaced the Control Module. A known problem with a bad solder connection on heater relay. Removed door front panel containing control module, wiring, door latch, and ON/OFF switch. Unsnapped the holding brackets (mostly plastic) from the front cover, then the control module. Unplugged control module, then carefully worked it out of the metal framework. Reversed procedures to install a new control module. Was careful handling the front cover, as the "piano key" pushbutton switches and red "lights" would have all fallen out, all over the floor. 

Replaced the control module PS the correct replacement part was delivered next day.........Thanks AP 

I hired a repairman several years ago to replace the control module in our 2001 Bosch dishwasher. When it quit working with the same symptoms, I decided to try to replace the module myself. I watched a Youtube video showing the replacement of a control module in a Bosch dishwasher. This was a different model than mine but it still looked simple enough. I ordered the control module from ApplianceParts and it came promptly in two days. I first turned off the power. I then proceeded to follow the video until the module was exposed. The only problem was in figuring out how to remove the module since it was different from the Youtube module. I finally figured out how to remove it and replace with the new module. I had taken a picture of how the wires were installed on the old module so I used this to make sure I had installed them correctly on the new module. I installed the door covers with the help of my wife with no problem. I turned on the power and pressed the start button on the dishwasher. The unit started counting down but I wasn't sure it was working properly. I remember the repairman stating that he had to do a reset. I looked online to determine how to do a reset. I depressed the ON/OFF BUTTON at the same time as the SCRUB WASH and DELICATE/ECONOMY buttons and held for 3 seconds. The unit then starts counting down and when at the end it is reset. I turned it off and then on and it works perfectly. Sorry Mr. Repairman but I don't need you. 

Based on information from this site and others, I determined that my Bosch SHU6802 dishwasher needed a new control module. The repair seemed pretty straightforward until I inadvertently removed the screws holding the inner door frame to the hinges. Hint to those of you considering this project, don't remove the four larger screws on the bottom part of the door that point toward the middle of the door. If you do, the repair just became a lot harder as you'll likely have to wrestle with the hinges to get that part of the door reattached. A pro would probably pull the dishwasher out, remove the side panels, and disconnect the hinge pulleys to properly reattach the door. I didn't want to do that for several reasons, and I eventually used a couple pairs of Vise-Grips to give me some leverage on the hinges and enlisted the assistance of my wife to hold one side open at a 45 degree angle while I attached the other side. Anyway, during the hinge mishap, the front panel of the door (from which I had already removed the screes) fell to the floor breaking the power module. So I got the control module in without too much trouble but had to go back to Appliance Part Pros for a power module. Fortunately, it was in stock and shipping was amazingly fast. Ordered it on Thursday evening and had it on Saturday. Replacing the power module was easy, and I was finally out of the doghouse. Thanks! 

Bought a replacement controller. Unplugged the power. Removed front cover of the door. Unplugged the wires and the old controller snapped out. Snapped the new controller in and connected the wires. Reinstalled the cover on the door. Plugged the power in and I was finished. The whole thing took about 15 minutes. The dishwasher works great, 90 minute run time. Couldn't be easrier, but you will need a torx driver. Ted 

Ordered new control module and paid $100 for a repairman to install it. 

Replaced the wax motor and despenser door assembly. The door still did not open so I called Applicance Parts Pros and they suggested replacing the electronic module. I replaced it and the dishwasher works like new. Replacing the module took about 10 minutes. Our Bosch dishwasher is about 18 years old and this is the 4th module to be replaced. Apparently the module is the weak link in the SHU5316UC dishwashers. 

I read that other people had similar problems with their older Bosch units and that most of the time it was the Control Module that caused the problem. I ordered the replacement module from APP it arrived promptly as promised. I did have a problem with the new module plastic case which came with one of the plastic tabs that the control panel buttons engages with being broken but I was easily able to swap the circuit boards from the new module in the case for the old module. The diagrams on the forum were very helpful. The whole process including searching for dropped door panel screws took 40 minutes. The thing that took the longest was getting the door panel back on and aligned properly so the screw holes would align. The dishwasher worked flawlessly when I tested after putting the power back on. 

Installed new control module. DIY'ers need to know that the top on the old installed module needs to be opened and to gain access to the clips that hold it in place. Once released the module lifts out easily. 

Replaced control panel/board.
