Question about Bosch Dishwashers

1 Answer

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

Most likely the control unit is defective.

SOURCE: No sound from Subwoofer. Traced fault to subwoofer

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 :)

Bosch SHU 3032 dishwasher gets stuck halfway through the wash cycle and just continues to wash until you manually advance it. I turned in on before bed one night and it was still running the next morning....


Hi,
It obviously sounds like a timer issue here, and as it's embedded in a big chip on the control board, I would think a new control board is needed.
The exception to this is if it is not heating at all, in which case it won't advance if the water is not hot enough. Try it again and see if it gets warm.
If not - replace the heating element.
Most machines just stop to heat up the water, but to cut down cycle time they may recirculate the wash-water first to speed things up.

S5N27B keeps stopping mid cycle


If the cycle doesn't complete, check these:---
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows: On some units, the pause is timed and the unit continues after the allotted time. On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too. Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

Running time of dishwasher


he cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. 

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Cycle not completing See "The cycle doesn't complete" section.

Hi my hoover 6612 dishwasher does its pre-wash but then when the light for wash comes on it does nothing. I wondered if it might be a capacitor which needed replacing but I can't find one - any ideas??


Check the float switch inside the tub, it should move freely up and down.

Check the harness to the motor

Check start capacitor on the left side of the wash motor

Dishwasher draining - Bosch SGV4313GB/17


This is generally because of a stuck diverter solenoid. The water goes to the pump and then is either sent to the wash arms or the drain. Also, check the drain.

About the led: If your dishwasher has a digital readout and you see an error code, it may indicate a problem with the unit. If this happens, look up the error code in your owner's manual to find out what the problem is.
