Bosch Dishwasher Error Code E01: 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 E01
- A failed relay, triac or processor on the main control board
- A loose ribbon cable or connector between the user interface and the main board
- Heater relay contacts welded or burnt on the module
- Moisture, a power surge or corrosion damage on the electronics
How to fix it
- Disconnect power for at least five minutes to let the electronics reset, then restore power and see whether the code clears.
- Open the electronics enclosure and look for burn marks, swollen capacitors, water traces or loose connectors.
- Look at the module under the lower door panel for dark spots near the heater relay terminals.
- Reseat every connector and ribbon cable on the control and display boards.
- Check the supply voltage at the outlet to rule out a brown-out or bad ground.
- If the code returns straight away, replace the control module using the exact part number from the model/serial tag.

Questions
What does error E01 mean on a Bosch dishwasher?
The dishwasher electronics detected a fault inside the control module or in the heater relay circuit and has stopped the program. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my dishwasher while E01 is showing?
Possibly, if the machine still starts, but a failing board can misbehave at random, so plan a repair.
How do I clear E01, 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.
