Question about Bosch 24 in. SHU53 Built-in Dishwasher

2 Answers

I own a Bosch dishwasher that has operated perfectly for about ten years. The model is: SHU9915UC. Now it wont complete the cycle. The undissolved detergent is all over the dishes. After running 4 more complete cycles without any detergent the same undissolved powder detergent remains on the dishes. I have also executed a cancel/drain cycle. The filters are not clogged. I am great at repairing many tools and automotive "stuff" and don't want to call a repair facility. Please help.

    Can you provide me with a part number for the timer? And also the location for this part? After which I can based on price choose to "troubleshoot" by beginning with the replacement of this part and then see if the problem goes away. I have a great appliance parts distributor in my area but if you know of an online source that is reliable that info would be great too.

Hello,

Welcome to FixYa.

I just read your previous post and I wouldn`t replace that timer/control just yet. There is a way to visually inspect the control.

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.

I own a Bosch dishwasher - dabfa62.jpg

The culprit will 99% of the times be one of the pins from the heater relay,

**Flip this over and inspect the solder joints, it will be obvious when you see it.**

This ones new, but it's where to look...

...hence the unit doesn`t desolve the detergent properly or clean worth a darn because it can`t heat to the required 155° in wash to 160° in rinse


You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow switch indicates it has adequate water to engage the heater.

**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power or turn off the breaker before attempting any service to the dishwasher.**


As you alluded to though, if you buy and replace the control It will resolve the issue as well.

Hope this helps before spending money perhaps not necessary.

Let me know if I can assist you further. Thank`s for visiting "FixYa" for your repair inquiries.

Please take a moment and rate this solution to it's helpfulness.

Good luck.

Regards,

Macmarkus :)

    Hello,



    I forgot to add the part number should you choose that avenue is 481055 and available at most appliance parts brick & mortar locations or on-line vendors such as "searspartsdirect.com" repairclinic.com" or "appliancepartspros.com" to name a few.



    It will also differ in appearance then my example, but the same diagnosis process applies as does the access to the unit and oipening the plastic case to visually inspect for burnt solder joints or pathways/circuits.



    Yours will look like this ( in the door assembly at the top below the push-buttons)



    i.e.






    Let me know how you make out and what you find.



    Again though, good luck.



    Regards,



    Macmarkus :)

Hi


Thanks for using FixYa. If the cycle doesn't complete, then the first thing that should be checked is the Timer and then the heating element. 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. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Beeping sound when cycle is finished just started after 8 years. how do I turn it off?


Hello,

Welcome to FixYa.

I think can answer your question..."beeping sound when cycle is finished just started after 8 years. how do I turn it off?"


Follow these steps...

**How to Operate the Cycle Completion Signal**


1. Open door, hold down program button (see
Beeper Table below) and simultaneously turn the unit "ON".


MODEL Program BUTTON

SHU 9950 Delay Start Hours
**SHU 9910-9920 Delicate/Econo** should be yours
SHU 8800/8810 Quick Wash

SHV 6800 Delay Start Hours
SHV 4800 Delicate/Econo
SHV 4300 Delicate/Econo


2. Release program button.
a. For SHV 6803 and SHU9950 models:
The display will blink with a code of "0", "1" or
"2". You are in program mode.

? If the display blinks with a "0", you will hear
no signal (indicates OFF).

? If the display blinks with a "1", you will hear a
LOW volume signal.

? If the display blinks with a "2", you will hear a
HIGHER volume signal.

b. For all other models with the beeper
function:

? If the machine beeps, then the Cycle
Completion Signal has been enabled.

? When you push the button again and it does
not beep, it means that the Cycle Completion
Signal has been disabled.

3. To change the program, press the program
button until the desired setting is selected.

4. Turn the Dishwasher off to take it out of
program mode.

* At the end of a wash cycle, the beeper will sound
off two times, and again every 15 minutes until the
dishwasher is turned off.

Hope this answers your question and provides you with what you needed.

Thank you for choosing FixYa and good luck.

My Bosch Model SHU9915UC is not filling up with water. This is not a brand new unit about years old been idle for the last two years.


When any electronic mechanical device is left for any period of time, and has NOT been periodically Powered Up. It WILL need a complete overhaul,apart from electronic components going out of spec, especially capacitors, also the Valves and things get jammed up. and seize. 2 years is too long of a time to expect it to just "work" again. It will need to be attended to by a professional.I know this is most likely NOT what you want to hear, but it is true and will have to be done.
