Bosch SHU9915UC Dishwasher - Page 2 Questions & Answers
My bosch dishwasher will not stop running, plus
Hello,
Welcome to FixYa.
Based on your description I'd say the issue actually with the control...unfortunately.
**B/S/H/ also issued a recall on certain models between 1999 - 2006 depending on the model & serial number, you can check with yours, though many not included here still suffers from the same problem...you'll need the serial number too. Here`s the link if you want to see for yourself **
http://microsites.boschappliances.com/safetyrecall/dishwasher/
As I've alluded to the issue is likely within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).
If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself...it really isn't very complicated.
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.
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 sit`s and takes longer & longer to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed...or takes a long time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning and obviously no "extra" heat ( aside from the water inlet temp. ) as a result.
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.
i.e.
**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.**
If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau/Siemens, to service your machine.
Hope this answer`s your question, let me know if I can assist you further.

I have to constantly do a manual drain which seems
i have the same problem....i would think the inlet valve is leaking....that would be the mechanism where the water supply is attached to the dishwasher.......did you get yours fixed? can you help please?
Bosch Dishwasher Not Draining
Im really not all that familiar with the bosch unit, but a few things i would ck. when you cancel a cycle (it should drain the water) is it humming??? does it sound as if it even trickling into the sink discharge?? do you have a disposer under your sink that this unit drains into, if so remove the clamp and look for possible obstructions right there.Honestly passed this ill have to defer to someone else sorry and good luck
My dishwasher(Bosch) makes sqeeling sound
Hello,
Welcome to FixYa.
Based on your description " makes squealing sound almost like beeping at the beginning of its cycle "...it is likely to be either the pump impeller or the inlet valve.
With the Bosch built line of dishwasher`s this is a known problem...the carbon ring ( spring ) of the impeller pump seal kit. ( make sure it is indeed a SHU9915UC before ordering parts )
**Most common in units not used regularly, i.e. in a holiday cottage or vacation property, but time to time on daily used as well unfortunately...but also due to the heat from normal wear & tear**
You first must determine which is the source of course. Does the noise begin after filling with water and the pump starts, or does it begin upon the filling of water ?
If it's the valve, make sure the water supply line is completely "open" and if so replace the valve with part #425458
i.e.
If it is the motor wash impeller squeeling It can be remedied by one of two methods, replacing the entire motor & pump assy part # 442548...
i.e.
This retails between $99.00us. to as much as $170.00us. depending where you look. I usually go through "searspartsdirect.com" for about $100us. ( you can also investigate "repairclinic.com" or "appliancepartspros.com" to name a few.
Or if you are mechanically inclined, replacing the pump impeller kit. part # 167085
i.e.
The kit is typically around $50 -$75us, hence it can be cheaper when factoring labour for the complete motor/pump assy.
This is a pretty involved repair to explain, in fact I think it is harder to explain than actually do...but I`ve done many.
If you`d like to provide me with an email address I can attach a file in "pdf" showing you step by step how you can do this without much cost at all really...likely your time will be the greatest expense.
Let me know how you`d like to proceed and I`ll help in whatever manner I can.
Thanks for choosing FixYa and Good luck.

My bosch dishwasher won't start
see this causes and fix it. God bless youPower Supply
The main power supply is the first thing to check. Also remove the toe
kick and the cover on the power box and check the connections. Also check for 120 volts at the power box.
Hi - Limit Fuse
This will fail if your dishwasher overheats and occassionally with power
surges. This is easy to check, inexpensive and a quick fix. Just check
the terminals for continuity ( remember always remove one wire) if you
have none replace the hi limit fuse
Door Switch
This is the second place to look. Again an inexpensive easy fix. The following video will walk you thru checking the door switch. . The power comes into the main power box and usually runs to the door switch next before entering the main control module.
Main Control Module / Timer
The main control module or mechanical timer controls all the functions
of the dishwasher. To check this you will need to find the 2 leads that
supply the power to the control. They will be marked on the wiring
diagram. They usually come from the hi - limit fuse or the door switch.
When the door is latched you should have 120 volts entering the main
control. If you do not the problem is not the control. If you do have
power entering the control but none of the functions work properly or it
does not respond at all you will need to replace the control module ,
this is easy to replace but not very inexpensive to purchase. Consider
the age and overall condition when purchasing this part.
Motor
The motor may have failed. If the control illuminates on electronic
versions the problem may be the motor. To check the motor refer to the
tech sheet located behind the console cover on most models, this will
sometimes have the ohm reading of the motor. Also check each lead to the
metal housing of the motor to check for shorts in the motor. If you do
not have the ohm reading specicifications, check for continuity if none replace the motor Make sure the motor is receiving power
Float Switch
If the float switch has failed or is stuck the dishwasher control may
not respond. The float switch is easy to check and replace.
