Bosch Dishwasher Install Fascia Before Roof
My Bosch dishwasher was broken recently. It kept running for hours. Here is how I fixed it:First, the symptoms: The dishwasher would run for a long time. It didn't really get things clean. When the door opened the inside was not warm.The first step was running the built-in diagnostics.
To do this press the Power Scrub and Regular Wash buttons at the same time, then press the power button. One of the lights will show up.If the WASH light shows, that indicates a heating faultIf the RINSE/DRY light shows, that indicates a filling faultIf the CLEAN light shows, that indicates a NTC (Temperature Sensor) fault.Mine showed WASH so there was a heating fault. When this shows it can be a problem with the heating element or the electronics.One of the common problems with this dishwasher is that the solder joint for the heating circuit can burn out. It is pretty simple to fix if you have a soldering iron and a torx screwdriver (#20 size). The circuit board should be checked before replacing the heating element because it is faster and easier to check and repair.Step 1 is to unplug the dishwasher.
Even though the wires to the power switch are insulated, it is always a good idea to make sure there is no power going to the dishwasher.Step 2 is to remove the Fascia - the front part of the dishwasher with the buttons on it. To do this you use a torx #20 screwdriver. Open the door and remove the screws from along the top edge of the door. Remove the two screws from the side which hold the control panel in place. I also remove the two screws at the top of the front panel to make it easier to get the control panel in and out.Once the screws are removed, the control panel can be pulled up and forward to free it from the door.Once this is done, disconnect the wires holding it in place.
First the connectors to the control module:Then the connectors to the Power Switch and the Ground Wire:When these are disconnected, you can remove the panel entirely and set it on a soft surface. It is possible to skip disconnecting the wires, but it requires juggling a half-open door and a wobbly control panel while you try to unclip the control module.The next step is to unclip the control module. There are plastic clips at both sides that need to be opened and then the module rotates free with a hinge at the upper side:Unclip by sliding a flat screwdriver or other tool under. Do not bend too far or you risk breaking off the clip.Swing the top up so you can get to the next set of clips which hold the circuit board in position.
These are similar to the first set, but smaller. You can use your fingers to release them.Once those clips are open, you can pull the circuit board up to see the back side.Once it is visible, look for a burned solder joint near the middle of the board as shown in the photos. It will look something like this:Clean the joint with an x-acto knife or whatever else you can use. Then get out the soldering iron and resolder the joint. Put it back together in the reverse order you took it apart.
Don't forget to plug it back in!Test by running a wash cycle. If the heater comes on and the wash cycle is back to normal times (about 90 minutes) then you have fixed it.If you can't succeed in repairing it, the whole module is typically available for about $150. Any appliance with electronic touch controls benefits from being plugged into a surge protector, just like the kind you buy for a desktop computer.
Obviously it keeps any power problems from frying the circuit board or sometimes the non-replaceable fuse. I learned this from an appliance repair guy after the local power company touched two wires together when they were working on the lines and fried my dishwasher's control panel. $300 for a new one! (Yes, they eventually reimbursed me.)Posted byJonny D Posted on. I came across your site after many searches and worrying about about buying a new control panel. The last one cost around $450 and was replaced on warranty back in 2000.
The Bosch 6800 Dishwasher is a nice unit but I couldn't justify spending around $600.00 plus for someone else to do the work or parts. I would have just purchased a new dishwasher.Your step by step is actually what I needed to really understand the problem. The only money I spent was on a new soldering iron and some 40/60 rosin core solder for a grand total of around $60.00. Thank you and if ever I have another problem, yours will be the first site I visit. It was also my first solder job on a circuit board and it held up!BibPosted by Posted on. Great and timely advice. My Bosch SHU43 was having the exact same issue, hanging at 1 minute remaining and not completing rinse or heat cycle.Performed this procedure and sure enough, a clearly fried soldering point.
My control module box was a bit different and had to patiently open it up without breaking plastic tabs to observe the circuit board.A couple quick tips:-Take pictures of the plugs leading to the control module before disassembly. It helped reassemble correctly.-The entire front panel assembly was a bit fussy going back in. There are metal tabs in the interior door panel that align to slots in the front panel frame. It helped to loosen the Torx screws along the length of the stainless steel interior panel to allow for additional wiggle room when aligning the front panel with the tabs.Overall, a super solid tutorial and saved me potentially $200-$300 for a technician to replace the control module. Thanks so much for taking the time to post the instruction!!!!Posted byRandy Posted on.
Bosch SHE44C05UC: Thank you for documenting this repair in such detail. We have the SHE44C model (purchased in Oct 2006) so the workings were a little different but still close enough to get the job done. Your posting gave us the confidence to give the repair a try. Thanks to the other comment posters as taking a picture of the wire connectors proved helpful when putting everything back together and we were extra careful with all the clips. All is working great!
Thanks again!Posted byQuinn Posted on. I have a Bosch SHX45c02uc model that had the same problem as discribed above. This model has the hide away buttons on top of the door.
The disassembling was a little different from your photos but close enough for me to figure it out. The burnt solder joint looked identical to your photo. As suggested above I took digital photos of the wiring prior to disassembling.
I completed the repair in less than an hour. Thanks to all for posting this stuff on line.
Between repair forums and YouTube videos I have been able to fix my furnace, snowmobiles, refrigerator and now my dishwasher. The Internet holds a vast amount of informative information. Take care.Posted byPaul Ferry Posted on. Followed the instructions today and they worked like a champ. Our dishwasher kept sticking at the one minute mark and would run for hours.
It also wouldn't dry the dishes like it used to and it left a white film on the dishes. After applying this fix, the timer worked as designed, the dishes were dry and no white film! Like others, my dishwasher was slightly different, but the steps pointed me in the right direction.
I've never soldered anything before in my life so I went to Youtube to learn how. I purchased a $21 soldering gun and went to work. My joint wasn't as nice as the instructor's on Youtube, but it worked nonetheless.Thanks for posting these instructions!
You saved me hundreds of dollars!Posted byMike Posted on. Also worked on my SHX33A or SHX33A05UC/46 to be more exact.My symptoms were the same- 3 hours, 50 minutes run time for Normal Wash. Open the dishwasher, still dirty dishes, some suds at the bottom from the rinse agent, all because it wasn't heating the water hot enough. Sanitized light wouldn't come on at the end. Household temp is 120, but this machine heats it up to 135 in wash and 150 in the rinse cycles.Entering the Diagnostics was slightly different for this model, but it doesn't matter, I had to also solder a heating relay contact on the circuit board.After putting the board back on, I left the front panel off, ran a diagnostic test run, and rested a thermometer my wife uses when steaming milk on the inside panel just above the soap dispenser. Sure enough, the temp slowly rose from about 100 up to 135 at which point, roughly 20 mins later, the diagnostic run was satisfied and the drain cycle kicked in. Re-attached the front panel and then ran a Normal wash cycle which now finished in about 90 minutes, and the Sanitized light is now also back on.This post saved me hundreds!
Thanks!Posted byPaul Posted on. Thanks for posting this.
My SHU 9955UC/14 purchased in 2003 developed the same problem after about 10 years of use. It is apparently not part of the recall.The location of the pin on the circuit board is different than in the older models, but the burned solder joint was evident once I disassembled.
Your posting allowed me to diagnose and fully repair my dishwasher in less than 2 hours for free! I would have lost 2 hours of work and $100 for a repair call.Thanks!Posted byFred Terry Posted on. I am very impressed with the post, grateful to the poster, and disappointed with Bosch.I was resigned to replace my 6 year old dishwasher and then I found this site.
Although my components were a little different the symptoms were the same. I had a little trouble putting the face back in the door but the repair worked like a charm.
I just wish the sour puss at the Bosch'help line' could have told me about this instead of telling me about some repairman 105 miles from my house.Posted byDavid Posted on.

My Bosch dishwasher model is SHU33A06UC/47, so it looks a little different inside but was experiencing the same issues as many others have with this defect: 3-hour cycle, no sterilized light, lots of suds.
I decided to open it up and give it a go anyway. Even though the board was a bit different, thanks to the pics I was able to spot the problem with the bad solder joint. A drop of new solder, put it back together, and it WORKED!
Thanks so much for putting this info out here on the web. A half hour and a drop of solder has saved hundreds of dollars that I would have had so spend on a repairman visit and likely a new control module.Posted byMike in SC Posted on.
