If your Bosch dishwasher displays the E02 error, don’t panic. This common issue usually points to a problem with the heating relay or temperature sensor. In simple terms, your dishwasher is having trouble heating the water properly — and without hot water, it can’t clean dishes effectively.

The bosch dishwasher e02 error often appears due to a faulty relay on the control board or a worn-out temperature sensor. Sometimes, it can also be caused by limescale buildup or a loose wire connection. Before calling for help, there are a few things you can try yourself.

First, turn off the power and unplug the machine. Then, remove the front panel to access the control board. Check for any loose connections or signs of corrosion. You might also try resetting the dishwasher by holding the Start button for 3–5 seconds.

If you're comfortable using a multimeter, you can test the temperature sensor for continuity. If it's defective, replacing it could fix the problem. A new sensor usually costs around $20–$40.

However, if the issue lies with the control board or relay, repairs can get trickier. At that point, it’s wise to call a qualified technician. For a bosch dishwasher e02 error, professional repairs typically cost between $150 and $300, depending on the model and parts needed.

So, when should you call a pro? If you’ve checked the wiring and sensor and the problem remains — or if you’re not comfortable opening up your appliance — it’s best to leave it to the experts.

Now you know what causes the bosch dishwasher e02 error, how to troubleshoot it, and when to seek help. Don’t ignore it — your dishes and your machine will thank you.
