Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things...

Bought new spray arms online and installed them in minutes...now the thing works like new...

However I have also found that if the heating element goes bad then that also can mess things up bad...

So I would buy new spray arms, and also check out the heating element to make sure it is working...


Here is a tip that will help you with the online buying...

Hello, welcome to FixYa.

Based on your description I'd say the issue actually is with the control...unfortunately. This is commonly associated with a heating fault on Bosch built dishwashers ( various models including Bosch, Thermador, Siemens, Gaggenau, and Neff ).

Since 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 not advnacing past 1, but not very probable ). These are the steps you'll need to follow to resolve it or at least investigate.


I'd also like you to varify the model number, I think there be a couple of digits missing from the number you posted. It will be located on the side of the door as shown in this example,

macmarkus_867.jpg

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, 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...this can also manifest as a long cycle time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning, no heating ( don't be fooled by the homes inlet hot water temperature ) 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.

**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. Bosch recommend`s replacing the control and I don`t pretend to speak on their 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.

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 :)

Westinghouse sb915 - draining too early.


1. Is your drain point higher than the bottom of the dishwasher? (ie, does it drain into the garbage disposer or does the drain line drop down below the floor into house plumbing?) Did you just install the unit? You may have to install an "air gap" to prevent syphoning.

2. Did the dishwasher work then suddenly stop working? (asking for clarification)

Hi there, did you ever find out what was wrong with your dishwasher? I have a Westinghouse 904 doing the same thing but when we moved into this house the manual was long lost. Any thoughts would be greatly appreciated.
