Hello, welcome to FixYa.

Based on your description
I'd say the issue actually with the control...unfortunately. The "1" being displayed is actually an error code associated with a heating fault.


**B/S/H/ issued a recall on certain models between 1999 - 2006 depending on the model & serial number, you can check with yours but...you'll need the serial number too. Here`s the link if you want to see for yourself **

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...

9119d99.jpg

...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 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.
Thank`s for visiting "FixYa" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness. Good luck.

Bosch AquaStar 125b ng suddenly goes cold during shower


Does it happen to any other fixture? If not, it's most likely your shower valve and not heater.

No manual for my dishwasher


This is not the kind of thing you want to tinker with without a manual. You'll need the model# and serial # to contact Bosch and get a manual.
