What dr:11 Means
dr:11 on a Bosch Vision front-load washer means the inverter has seen supply voltage below what it needs to drive the motor. Bosch's documented cause is a weak power supply and the only remedy given is to check line voltage. Because motors draw most heavily at the start of a spin, this often appears at that moment rather than during a wash.
Common Causes of dr:11
- Supply voltage sagging under load
- Extension lead or undersized circuit feeding the machine
- Loose connection in the branch circuit adding resistance
🔧 One Safe Check You Can Try
Check whether the washer is on an extension lead or sharing a circuit with a dryer, heater or another motor. Bosch points at the supply, so household wiring is the right place to look before the appliance.
⚠ Why You Shouldn't Go Further Than That
- A loose connection carrying washer current heats the joint, which is a wiring hazard rather than an appliance complaint.
- The measurement that matters is taken while the machine is spinning, not on an idle outlet.
- Nothing inside the washer will correct a supply problem, so dismantling it is effort in the wrong place.
- Motors run on low voltage draw more current and get hotter, so ignoring this shortens the life of a healthy drive.
