Step-by-Step Fix
- 1
Stop safely
Pause the programme, wait for the drum to stop and do not force the door.
- 2
Check settings and symptoms
Do not use a washer with a damaged or leaking seal; clean only an intact seal by the exact manual.
- 3
Record details
Note the programme stage, any code and the PNC/product number.
- 4
Follow the exact manual
Perform documented user checks only; dismantle nothing and make no electrical measurements.
- 5
Arrange service
Stop if the issue remains or the seal, heater, motor, electronics or internal mechanics are suspected.
When to call a service technician
Arrange authorised service if the problem remains after external checks. Do not use the washer with a damaged seal, leakage or abnormal mechanical movement.
Unplug immediately for water near electricity, burning smell, smoke, abnormal heat, tripped protection, sparks or severe grinding or scraping.
Prevention
Follow load limits, empty pockets, close zips, leave the door ajar after use when safe and clean the seal and accessible areas as the manual specifies.
Keep the washer level and select the correct programme; this does not prevent internal component faults.

Frequently Asked Questions
Can I keep using a Bosch washer showing —?
Do not use a washer with a damaged or leaking seal; clean only an intact seal by the exact manual. Do not run another cycle until Bosch guidance or service confirms it is safe.
Can I reset — by switching the washer off?
Switching off is a safety step, not proof that the fault is repaired. If the code returns or Bosch classifies it as service-only, do not repeatedly reset the washer.
Does — identify a part to replace?
No. The code identifies a system or condition, but Bosch service should diagnose the exact cause before any part is ordered.
Why should I provide the E-Nr?
Bosch model families and markets can use different hardware and service procedures. The E-Nr identifies the correct appliance documentation.
May I test the sensor myself?
No. Do not remove panels or measure internal wiring, sensors or electronics. Bosch directs these codes to customer service.
