Bosch Dishwasher Error Code E05: Meaning and Fix
Reading the dishwasher display
A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Bosch shows the code with a leading E and a number on both dishwashers and washers.
Bosch (part of BSH Home Appliances) uses E-numbered codes on dishwashers and washers. Its dishwashers share control platforms with Thermador and Gaggenau, so the same fault can appear on those brands. The codes apply to model numbers such as SHPM65Z55N, SHE53T55UC and WAT28400UC; check the label on your unit to confirm yours.
What causes E05
- A temperature or level sensor that has drifted out of range or failed open/short
- A loose or corroded sensor connector or broken lead wire
- Failed heater relay that never switches off
- A control board input that misreads the sensor signal
How to fix it
- Unplug the appliance and locate the sensor named for this fault in your service sheet or parts diagram.
- Inspect the sensor, its lead wire and plug for damage, moisture or corrosion; clean contacts and reseat the connector.
- Unplug the machine as soon as you see the code, since the heater may still be live.
- Measure the sensor resistance with a multimeter and compare it with the value expected at room temperature.
- Replace the sensor if the reading is open, shorted or far from spec.
- Power back up and run a short cycle to confirm the code does not return.

Questions
What does error E05 mean on a Bosch dishwasher?
Water temperature in the sump exceeded the safety limit, so the program was ended. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my dishwasher while E05 is showing?
Often yes for a short while, but with reduced performance because the control is running blind; get it checked before it causes a heating or flooding problem.
How do I clear E05, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
