Reading the washer display

On a washer the code appears on the digital display or as a pattern of flashing cycle lights. Note it exactly, including any dashes or sub-codes, then unplug the washer for five minutes and run a short drain cycle to see whether it returns. 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

How to fix it

  1. Disconnect power for at least five minutes to let the electronics reset, then restore power and see whether the code clears.
  2. Open the electronics enclosure and look for burn marks, swollen capacitors, water traces or loose connectors.
  3. Dry the area, reseat connectors and inspect for greenish corrosion.
  4. Reseat every connector and ribbon cable on the control and display boards.
  5. Check the supply voltage at the outlet to rule out a brown-out or bad ground.
  6. 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 washer?

An internal electronics fault was logged, suggesting the control module has lost communication with its drive. Exact behavior can vary by model and software version; confirm against your own manual.

Can I keep using my washer 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.
