Bosch Washer dr:02 Indicates an Inverter Power Switch That Is Open

What dr:02 means

A drum that fills and then won't budge, or spins in only one direction, matches dr:02. Inside the inverter of a Vision front-loader, one of the switching devices that feeds the motor has failed open, the reverse of dr:01. Bosch cites damage in the inverter control and gives a new inverter as the remedy. The washer may still fill and drain normally.

Common causes of dr:02

Switching device in the inverter burned open
Damaged control section in the inverter
Internal connection broken in the inverter module

✓ One safe check you can try

1. Cut power to the washer at the breaker panel. 2. Before you do, if possible, see whether the drum moves and which way. 3. Write that down for the technician. Seeing how the drive fails in part is a useful clue, and observing it costs nothing. 4. Leave the washer off until the visit.

! Why to stop there

Opening the inverter housing exposes high-voltage capacitors that can hold charge after the power is off.
A motor winding problem can cause the same behavior, so replacing the inverter without testing is a guess.
Trying to spin the drum by hand with the power on is a pinch and shock hazard.

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:02dr:02 questions

What does a one-directional drum mean?

The inverter alternates the motor's direction with several switching devices. If one is open, the drive loses a phase, and the drum may turn only one way or not at all.

Do I need a new inverter or a new motor?

dr:02 points to the inverter, but we confirm by testing the motor windings. Bosch's documented remedy for this code is an inverter replacement. We give you a written price before we replace anything.

Will the washer drain with dr:02?

Often yes, because the pump runs from the main control. The motor drive is what fails, so you may be able to empty the tub before the visit.
