Bosch Washer Dryer: not functioning

Professional Repair Guide

What is this symptom?

If your Bosch washer dryer is not functioning, you may experience total silence when selecting a program. This could stem from various issues, including a door that isn't securely locked, power supply problems, or internal component failures. Understanding the root cause can help you address the issue effectively.

Urgency: Medium

Important Tips for Bosch Models

  • Bosch manuals emphasize that error codes and secure door locking must be resolved before the washer dryer will start.

Possible Causes

Door Not Properly Locked or Child Lock Activated

How to Identify: Machine won’t start even with power applied; door doesn’t click firmly; child lock icon may be lit.

Part: Door lock mechanism / electronic lock sensor

Power Supply / Fuse or Breaker Issue

How to Identify: No lights, display, or response at all; other appliances on same circuit also not powered.

Part: Household circuit breaker / internal fuse

Control Board / PCB Fault

How to Identify: No start despite correct door closure and power; reset and diagnostics do nothing; intermittent behavior.

Part: Main control board (PCB)

Error / Fault Condition Preventing Operation

How to Identify: Error codes on display, flashing lights, or fault indicators; machine refuses to start until cleared.

Part: Software / error detection system

Internal Component Failure (e.g., motor, heater, drain pump)

How to Identify: No operational activity but power present; advanced diagnostics indicate specific part failure.

Part: Drive motor, heater, pump
