What dr:22 means

A sensor inside the inverter of a Vision washer tracks the temperature of the power devices so the drive can ease off before overheating. dr:22 says that sensor is dead, leaving the inverter unprotected from heat. Bosch's solution is to swap the whole inverter, since the sensor is built into it. The washer may run normally until it overheats.

Common causes of dr:22

  • Heat sensor on the power stage failed
  • Sensor lead broken at the module
  • Module damage affecting the sensing circuit
✓ One safe check you can try

1. No home test or fix exists for this one. 2. Avoid running long, heavy spin cycles while you wait. 3. Switch the washer off at the breaker if you will not be using it for some time. Do not treat this as a minor code, since the protection it reports is what stops the drive from overheating on a long spin.

! Why to stop there
  • Running without thermal protection risks cooking the inverter on a heavy spin.
  • The sensor is built into the module, so opening it is not practical.
  • Ignoring the code because the washer still runs can turn a module replacement into a motor-and-module repair.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

dr:22dr:22 questions
The washer still runs. Why worry?

Without its temperature sensor, the inverter cannot protect itself on a long spin. It may work until the day it overheats, and then fail suddenly.

Can the sensor be replaced alone?

Not on its own; it is built into the module, so the repair means replacing the module. We quote the whole repair in writing before starting.

How urgent is dr:22?

Less urgent than a shorted device, but not one to leave for months. Use light loads and short spins until it is fixed, and book a visit.
