I get my Bosch Refrigerator B22CS80SNS/01 failing since 2 days: No LED lighting inside, no display, no more electronic control but still cooling full speed! I found 2 boards on top. The right one is a Siemens ref# 900 308 803 and the left one is a Shaanxl Linghua Electronic ref# 9000281644. It has no 12V DC voltage but the AC 110V goes to it. I couldn’t find any other electronics and all connectors and AC connections from bottom (mains) seem OK. Any idea which board fails or if there is another 12V DC power supply unit somewhere else? I'm an engineer in microelectronics so I basically understand what we are talking about. Thank you

The temperature sensor is here, one for each section by the looks of it. Are you going to risk $100 $160 that is doesn't just need a top up of gas?

Hi, it sounds like the thermostat for the refrigerator is not shutting off and just continuing to cool to the point of freezing . You need to get it checked out and renewed .

Here's a link to the manual on searspartsdirect.com B22CS80SNS 01 BOSCH REFRIGERATOR Manual

if you mean light for water and ice dispenser they upgraded to a new led ring mine went out to you can get part from bosch parts website

The serial number is located on the inside of the refrigerator section, on the right side of the first vegetable bin on the panel.

Does ANYTHING work? Sure it's plugged in, breaker not tripped and GFI plug not tripped?
Plug something else into the outlet to confirm that it works.
Unplug from wall for 30 minutes to reset Bosch to defaults.
Still malfunctioning? Main control board is faulty.

You can get the manual here. on page 16 it tells you how to take off savagemode.

Sabbatical mode settings:
– Accoustic signal is switched off.
– Super cool or Super freezing
functions are ended (if activated).
– The interior illumination is
switched off.
– The light on the display panel is
reduced to basic lighting.
– Buttons are locked (except
“options” and “+” buttons).
Switching on and off:
̨ Simultaneously press “options”
and “+” buttons for 5 seconds
When switched on, [Sabbath] is
indicated on the display panel.

Good Luck

Helloduranjp,
Welcome to fixya.

You said, Your Bosch dish washer won't work. A number 1 is displayed on the electronic panel.

If it is displaying"01" then that means the extra dry setting is being applied!
Did you try to use the extra Dry setting?
Did the dishwasher work before this or is it brand new?
What is the model number and year?
Let me know ! I'm waiting for your response

Below is and example of the usage of 01 or 00 in a Bosch Dishwasher!

Extra Dry Heat
