Hiya, I have a Bosch Dishwasher SGV4313GB that wont heat the water, it gets stuck with cold water continually washing (pre wash??) the delf. Its a built in and I have opened the inside metal panel and exposed the control unit (PCB) there is no blackened/loose soldered joint to be resoldered. I am at a loss as to what else in the heating circuit to look for. Can you point me in the direction of what I should look for next? Kind regards Mark

just fixed one with that problem it was the vertical output ic Q301
that was shorted. try wicking it out. it is a LA7833S.
Postings say to be sure to use the Toshiba part

You can't get an original part unless you find a system on eBay or somewhere similar and take the part from it. Computer companies buy these speaker systems from other manufacturers, and treat them as just one big part. Under warranty they simply replace the entire unit. No components are offered (other than the wall-wart AC adapters when used). I went through this with Compaq/HP and Dell when I worked in service for a big retailer. Most people just buy a new system when theirs goes bad out of warranty.

Now, if you're like me (and I know you are since you're asking), you don't like to throw anything away if it can be fixed. Since this is the subwoofer, it's probably going to be on the floor or otherwise out of sight. So another possible repair is to get a replacement control with the same value as the original, solder some leads onto it, tack them to the pcb pads of the original, and just let the replacement hang out the hole where the original came through. Or you can be a little more ambitious and mount the new control properly, then wire it to the pcb.

Good luck in the repair, and thanks for using Fixya!

Hello, welcome to Fixya. What you're describing sounds like a bad control. I would still start by checking your water inlet temperature, the unit must be connected to a "hot" water supply line. If the water at your water supply is indeed hot it shouldn't be an issue, however you can try running the hot water at your sink tap to insure the cold water is out of the lines just before you turn on the dishwasher. If it is what I suspect, the control, this won't make any difference but it's worth a try. If on the other hand the water is good and hot entering the machine, you likely have an issue with the control as I alluded to. repairclinic.com carries them as part # 1102296 at a retail price of $185.65US however, I have a suggestion as to identifying the culprit if you're open to it thus confirming or dismissing the cause...but you may want to call in a pro. Since the issue with your Bosch dishwasher potentially lye`s within`the electronic timer/control, specifically the heater relay solder joint. You'll need to access the control for a visual inspection ( a faulty flow switch, ntc or heater can also cause this, but not very probable ). This is possibly one of the reasons why it runs seemingly forever (unless pressing the two buttons for "cancel"). To inspect and possibly repair your unit It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit runs & runs ( because it can`t heat to advance or until canceled ) trying to heat the water. **Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. Replacing the control will certainly remedy the problem. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)** **Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro as I alluded to earlier but with a word of caution, Insure it is one familiar with Bosch/Thermador/Gaggenau to service your machine.** Hope this answer`s your question's, let me know if I can assist you further. I will look for your reply. Please do reply either way, I've found after answering many of these questions I'm left wondering if the info was of any use to those asking. I don't know if perhaps a pro does get called in those cases and the "fixya" thread gets abandoned but I hope not. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness to you and leave a testimony if you're satisfied. Good luck. macmarkus :)
