Hi, we have just cleaned our Bosch HBC84K561B/02 combination oven. Now the microwave only runs for 2 seconds then stops. The door seal is straight and in good order. Any suggestions please? Stephen

Hi, I used a proprietary oven cleaner on the bottom and sides, and got some water in the bottom of the oven whilst cleaning out the residue. I have removed and cleaned the glass plate covering the aerial at the top of the oven. The appliance is 6 years old.
Expert:  Michael replied 8 months ago.

Hi Stephen,

Thanks.

I wouldn't do anything just yet.

It sounds like the control board is wet or damaged.

But Im betting on WET for now lol;-)

Open the door and run the oven for about 20 minutes 325 or so, with the door open. then turn it off. Next turn off the unit from the circuit power panel in your home please turn off the power to the oven for 30 full minutes then you can turn it back ON. Please let me knwo if that helped?

In any case, I will stick with you until this is complete.

Please rate my service kindly.

Thank you Stephen, fingers crossed for you here lol;-)

I can't leave the door open with the oven on as it is a built in oven. I am running the oven as I type.
Expert:  Michael replied 8 months ago.

Hi I understand, then you can run it with the door closed but open it as soon as you turn it off to allow steam to escape. This may take a few tries but it may very well fix you issue as i believe it has to do with too much moisture getting to the control board circuitry;-)

I have many years experience in electronics as well ;-)

Please rate kindly so I can remain with you for the duration until we have this working correctly ;-)

Thank yo Tech Mike

Hi, after 5 cycles of heating and cooling with the door open, no success I'm afraid.
Expert:  Michael replied 8 months ago.

Hi, Im sorry to hear that!

It may have been coincidence, or the board may have gotten wet possibly.

In any case.

Do you get any error messages? Or blinks or strange different beeps on the keypad display?

Thank you

Tech Michael

Customer: replied 8 months ago.
Hi, no error messages, just input the time for the power level selected and all starts as normal then 2 seconds later it stops and the display resets to telling the time. I have a technical background having looked after telephone exchanges, I have checked and tested the door switches both mechanically and electrically and they are operating correctly.
Expert:  Michael replied 8 months ago.

Hi Stephen,

Yeah the door switches wouldn't cause this problem in this way.

What happened is the main control board failed more than likley.

I need to know one more thing, does it sound normal when it runs for the two secs? Or is it any different sounding during that time?

Thanks Stephen.

Tech Mike

Customer: replied 8 months ago.
No it sounds perfectly normal.
Expert:  Michael replied 8 months ago.

Thanks,

you will need a new main control board, it is the one connected to the keypad.

Its easy to replace and no soldering just a few plugs and a ribbon cable to connect;-)

The best place to try for that board is: http://www.espares.co.uk/

I would call them for this as they dont list all the parts they carry on their site .

Please call espares: 0844 9777 888

Let me know how it goes?

Expert:  Michael replied 8 months ago.

Thank you and have a great day!
