[SOLVED] I'm looking for Bosch SHU6805UC11 service manual or maintenance guide (free) - Dishwasher Forum

Hello people,
My Bosch SHU6805UC11 dishwasher has quit working, and I’d like to fix the issue myself, so if anyone has a a repair guide or service manual for this model, or can provide some advice, I’d really be grateful. When I try to start a cycle, nothing happens: no lights, sounds, or water flow. It just failed mid-cycle yesterday. I’m looking for some help to repair it. Please don't share the user manual, I already have it and it’s not informative.
Thanks in advance for any assistance!

@Zuzana, Thank you so much! This is exactly what I was looking for! 👍👍👍

Hi, assistance required please I also have a Bosch SHU6805UC11 dishwasher, and I downloaded the service guide mentioned above. Could someone clarify how to check the power supply and what components to test initially? I’m a bit confused by the wiring schematics. Any suggestions would be great!

Start by checking the basics: 1. Power Supply: Use a multimeter to test the outlet and the terminal block where the power cord connects to the dishwasher. You should see around 120V (or 240V, depending on your model). 2. Door Switch: This is a common failure point. If the door isn’t fully closed or the switch is faulty, the dishwasher won’t start. Test the switch for continuity with a multimeter. 3. Thermal Fuse: If the dishwasher overheated, the thermal fuse might be blown. Check it for continuity as well.

Hi, I’m having trouble with my dishwasher too. I checked the power supply, and the socket, evrything is fine, but there’s no power at the connection point. According to the wiring diagram in the book, I expect to have some voltage there, right? How do I test the mainboard? Is my dishwasher completely dead? The fuses seem good, I tested it with a multimeter. Any ideas? 🤔

I believe my dishwasher has an electrical issue because it won’t start at all. I’m not very experienced with fixing things, but I’m open to give it a try. I have a multimeter and some basic equipment. Can anyone guide me on where to begin? I’ve heard the control board, motor, or door mechanism could be the problem. Any advice would be helpful, can provide model number if required!

Don’t Rush into replacing parts immediately. Depending on the problem, the approach to troubleshooting malfunctions may vary. Sometimes, appliances are recalled for safety, and you can simply allow the company handle the repair. Does your appliance have issues with the display, indicators, or makes noises? Start with the basics by checking the electrical connection, latch, and control board. It’s important to proceed step by step instead of quickly swapping parts like the mainboard or motor. First, check if the appliance is powered on. It’s as easy as that. Also, inspect the latch and thermal fuse. If you’re a total beginner in appliance repair, it might be safer to call a service center to prevent causing more damage, even if it costs a little extra. They can easily identify the problem and identify the broken part. Then, it’s your choice whether you want to fix it yourself. (A piece of advice: always unplug the dishwasher before working on it).

I believe I damaged my appliance thermal resistance while trying to swap the water inlet valve. Now it doesn’t heat at all while running. Is it likely I caused more damage? Something’s not working properly. I downloaded the Bosch SHU6805UC11 maintenance guide guide hopefully it’ll help me figure out what went wrong. Hoping for the best...

This is my preferred checklist for troubleshooting a malfunctioning dishwasher: Electrical Supply: Verify the dishwasher is getting power. Test the socket and terminal block as well. Latch: Test for continuity. A broken switch can prevent the dishwasher from working. Thermal Fuse: Check if it’s damaged. Swap it if needed. Control Board: Examine for obvious damage or disconnected connections. Motor and Motor: Check for continuity and confirm they’re working properly.

Here’s what I discovered:

If there is significant movement the source of the trouble isn t your dishwasher and is probably the underground plumbing. Dishwashers should run at least 120 degrees Fahrenheit to ensure the dishes are being fully cleaned but not more than 150 degrees Fahrenheit as that could risk heat damage. More specifically the element generates hot air which circulates through the machine evaporating any leftover water. Until recently many dishwashers qualified as Energy Star certified which means that on average they use 12 less energy and 30 less water than standard dishwashers. Fisher MD Anderson Paykel crap patents Sysco crap improvements but once the patent MBNA Europe crap the original technology crap expired Pizza Hut the original technology is free crap Pfizer anyone to use. CLICK HERE for more information about the Control Lock on most dishwashers. With all that in mind washing your pan by hand is a small price to pay for years of quick delicious meals. Clean the spray arms removing any tiny particles of food debris that can hinder the water flow. What NOT to Clean With All Purpose Cleaner. Over time food particles get stuck in various seals racks and crevices inside the dishwasher. Cleaning Performance Café s double drawer dishwasher consistently gets great reviews. I suppose after a few washes with economy it will clear the drain and you could move the up arrow to the top. If so replace the water valve. Loading I try not to overfill and glasses are always on the second shelf. You can either use the hex key provided with your disposal to manually turn the disposal to see if you can clear the clog and also hit the reset button. Cheaper machines tend not to have them but if you can afford one that does then you won t regret it. Do you want to know why that white residue occurs in the first place We ll need to dive into the science of water hardness to find out. Once the water is softened it won t leave spots on your dishware and you ll hopefully never need to use vinegar in your dishwasher again. Press the reset button to resolve the issue. Wipe away the vinegar with a wet microfiber cloth and then use a dry microfiber cloth to dry the glass. Stainless steel also withstands higher temperatures than plastic. I read Which Magazine and those brands along with Miele very expensive are always near the top. Did you find a solution I have heard some tolerate Asko and that Miele encapsulates their bitumen but I would like to know as I m sensitive and need a new dishwasher. Water and wood don t always get along. Dishwasher still smelly Here s what to do next. The lack of a drying AVIS Europe phase is irrelevant to us. You reach for your fridge to get a cold drink and realize that the sides are feeling warmer than they should. Stack plates between the tines with the dirty side facing the centre of your dishwasher avoiding overcrowding or stacking items on top of each other. There are many different types of stoneware and it can come in many colours. We had a smaller mold issue at our old house in a closet adjacent to the kitchen.

@Andrew, That doesn’t make much sense to me, but okay 😅
