If you have a multimeter set to continuity and see if it burnt out you might be able to replace it at an electronics part place also see if there are any fuses in there

Bosch generally drys through evaporation from hot water rinse. There is a common circuit board issue where a cold solder joint on the heater relay pops.The water does not heat sufficient to evaporate any longer. Consult your manual for self diagnosing trouble shooting codes or go to appliance aid.com.
If the board connection is the issue I have repaired several, however Bosch recommends replacement only and sometimes supplies the parts free.

you have to replaced the main control resoldering wont fix it because the relay itself has gone bad replacing the board will solve the problem

Actually all you need is a #20 torx screwdriver, a flat screwdriver and maybe a pair of needle nose pliers, but it can be done without the pliers if need be. The level of difficulty is hard to say since everyone has different and unique skills, but generally on a scale of 1 to 10 I`d say is likely a 2 - 3 depending on ones skills.

May I also inquire as to why you`re replacing the control ? Are you aware that typically the only thing which causes an error is the heater relay solder joint or the plastic tabs breaking off the casing which houses the control ? Did you know both are repairable ?

Anyway, just curiosity on my part, I digress.

**SAFETY FIRST - turn off the circuit breaker to the dishwasher before attempting any repairs or service to the unit**

I have a complete training manual I can send you if you`d like it, but you`d need to provide your email address, I can`t post it here it is adobe "pdf".

1) Remove the screws along both sides of the door panel until it is able to be removed, there will be either 2 plastic blocks which will fall out or molded styrofoam inside the panel, set the blocks and panel aside out of your way.

2) remove the screws around the perimeter of the control leaving the 2 ( one on each side ) facing away from the panel for the last.

3) once all the screws are removed the control fascia will be ready to pull away from the inner stainless steel door skin.

4) the fascia ( plastic cover with buttons/control face ) can now be separated from the inner control panel frame. If you observe closely you`ll notice it is only held together with tabs which need to be gently pulled away from the metal frame and then the fascia should pull off.

You should now be left with just a metal frame with the latch, power switch & rod and control board held in it.

5) All the wires in the bottom of the control will typically only go in one place, but it`s best to take a photo or mark them anyway...better sure than sorry right ? Remove the wires.

5) the plastic control casing is held into this metal frame only be tabs as well, push them inwards on one side and tilt the entire control back ( like it where hinged) and it will come right out.

6) This step should be much easier now that you`ve gained experience during the dis-assembly, reverse the steps to re-assemble it.

**if your door panel had the plastic blocks, they can be a pain to put back for one not experienced. The easiest way is to leave the two side screws out of the control panel to give it room to move into place at the top first and then down over the blocks.**

If you need help we`ll cross that bridge when we get there, get the control issue looked after first.

Let me know how you make out and if you want that service manual I can send you via email, it`s not very big...maybe 6MB or so.

Good luck

Depending on age and other factors; key pads do wear out and require replacement. Many of these controllers us a silicone positive touch system like the keypad on a computer. Others use a direct contact system that has a spring action and contact points. If the later fails, it can be due to use, a breakdown of the recoil system, or damaged contacts.

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.
Bosch has had a history of this exact problem I'm about to lay out for you and this is the first thing I'd be looking for if called out to service the unit with the symptoms you've described. **B/S/H/ also 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. The issue was directly related to the heating circuit (specifically the heat relay on the control) 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 ).

My first suggestion would be contacting Bosch re: the recall or calling in an authorized bosch service tech. if that is an option for you and your budget however, 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 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, 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.
