The Bosch E11 code means your dishwasher has detected a temperature sensor failure or a wiring issue in the heating circuit. In most cases, this requires inspecting the NTC thermistor or the heat pump assembly for resistance issues or loose connections.
E11 basically means your dishwasher's brain lost contact with its temperature sensor, and without that reading, it won't heat water. If you ignore it, you're running cycles with cold water and your dishes aren't getting sanitized. I usually find either a snapped wire in the door hinge area or a heat pump where the NTC sensor has given up. Neither is cheap, but the wire fix is totally DIY-able.

What Does the E11 Code Mean?
So your Bosch is throwing E11 and it won't finish a cycle. Here's the deal: the control board lost its temperature reading and it's not going to run the heater blind. It's a safety thing. I see this a lot after power surges, and also on machines that are 5-8 years old where moisture has been slowly working its way into the base and corroding connector pins. Parts are around $30-$200 depending on whether it's just a wire or the whole heat pump.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Faulty NTC Thermistor60%
Damaged Wiring Harness25%
Control Board Malfunction15%
Symptoms You May Notice
The cycle stops cold, usually during the main wash around the 20-30 minute mark, and E11 shows up on the display.
Dishes come out wet and still have food residue because there was zero heat during the wash.
You can hear the pump running but if you carefully feel the door area during a cycle, the water never gets warm.
Sometimes it'll run a full cold cycle and just throw E11 at the end instead of stopping early, which is confusing but it's the same problem.
Machine drains and then just sits there doing nothing with the error code on display.
Can you reset a Bosch dishwasher to clear the E11 code?
Press and hold the Start button for 3-5 seconds. You'll hear a short beep and it'll kick off a 60-second drain cycle, then the display clears. That's normal. If the repair actually fixed the underlying problem, E11 won't come back when you run the next full cycle. If it returns within the first few minutes of the wash phase, the sensor's still bad and you didn't get the right component yet.

Frequently Asked Questions
Can I still run the dishwasher with an E11 code?
Technically it'll let you start a cycle sometimes, but it won't heat the water and it'll probably quit mid-cycle anyway. Cold water means your dishes aren't getting sanitized, and if you've got a greasy pan in there it's basically just getting a lukewarm rinse. Not worth it. Just park it until you fix the sensor or the wiring.
Where is the NTC sensor located in a Bosch dishwasher?
It's built into the heat pump assembly, that big motor unit sitting in the base of the tub. On older Bosch units from the early 2000s you could sometimes replace just the sensor, but on anything made in the last 10 years or so, it's integrated into the pump and Bosch doesn't sell it separately. So if the sensor's dead, you're buying the whole heat pump. It's annoying but that's how they designed it.
What should the resistance reading be for a Bosch NTC?
At room temp, around 68°F, expect somewhere in the 10,000 to 55,000 ohm range. The exact number varies by model. What matters more is that it's not zero (shorted) and not open circuit. Also, if you have a heat gun or you can warm the sensor up a bit, the resistance should drop as temperature rises. That's the whole point of an NTC sensor, negative temperature coefficient means resistance goes down as heat goes up. If it doesn't change at all, it's dead.
Is E11 the same as E09?
Nope. E09 is the heating element itself, meaning the coil that actually heats the water burned out. E11 is the sensor circuit, so the heater might be totally fine but the board can't confirm the water temp. That said, they're both in or around the heat pump assembly on most Bosch models, so when I'm already in there replacing one, I usually test both while I've got access. Saves a second service call.
How much does it cost to fix a Bosch E11 error?
If it's just a broken wire in the harness, maybe $10 in materials and an hour of your time. If it's the NTC sensor which means replacing the heat pump, you're looking at $150-$280 for the part depending on your model, plus labor if you're not DIYing it. A repair shop visit for this runs $200-$400 all in. On a machine that's under 8 years old, it's usually worth fixing. On a 12-year-old Bosch, you're getting close to the conversation about whether to repair or replace.
How do I clear the E11 code after a repair?
Hold the Start button for 3-5 seconds. It'll drain for about a minute and clear the display. Then run a short rinse cycle and stand there for the first 10 minutes to make sure E11 doesn't pop back up when it tries to heat. If it stays clear through a full cycle, you're good.
