Yes, with caution
DIY difficulty
Moderate

How to fix it

  1. Power off at the breaker.
  2. Access the heat pump / NTC at the base of the dishwasher.
  3. Disconnect the NTC and measure resistance at room temp (~50k ohm class).
  4. Compare to Bosch spec sheet for the model; replace if out of range.
  5. Reseat the harness connector; clean any corrosion.
  6. Restore power and verify the cycle completes.

Why it happens

Typical signs: Cycle stops shortly after start · No heat phase · Error appears repeatably at the same step

  • Failed NTC sensor Resistance way out of spec at known temperature.
  • Wiring open to NTC Broken or disconnected harness pin to the sensor.
  • Connector corrosion Moisture in the NTC connector causing high resistance.
  • Control board input fault Rare, but PCB input channel failed.
