Thermador PG36 Gas Range/Oven is giving me a 21 flashing error code. Help!

We accidentally poured a fair amount of water onto the range top, which then dripped through the range and down out of the front of the oven onto the floor. Later, the "oven" and "heating" lights started to flash, 2 for "oven" and 1 for "heating." A quick Google search brought me to a Thermador document that says this means 21, or potentiometer, with an error code of E5. But that's where I get lost in the technical information. Any advice would be appreciated!

    A potentiometer is another name for a variable resistor that is often used to control an electrical a volume control on an old radio. does your range have dimmer for a light or something? If you have access to the the "guts" where the controls and electronics are you may be able to "blow dry" them out. A can of compressed air would be the first trick...then a hair dyer....doing this when the unit is power off is best. In 9 times out of 10 drying stuff out get them back in action...I have my fingers crossed for you.

    Thank you! Ultimately the lights stopped flickering and the oven went on again. Whoo-hoo!
  • There you go. As KMS said, dry out and you may get lucky. Yea!
