E:2051 is associated with compressor fault. Use the exact Bosch model number and the observed behavior before deciding what the appliance needs.
Model compatibility: Bosch reuses codes across series and model years, so Bosch Dryer E:2051 Error Code may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

When to call a technician
Compressor and inverter diagnosis requires model-specific electrical and refrigeration/heat-pump testing before parts are selected. Do not choose the most expensive module from the code alone. The technician should verify the relevant circuit or mechanism before recommending a repair.
