Bosch Dryer Error Code E:2082

E:2082 signals an overvoltage fault at the compressor inverter, which controls the variable-speed compressor in Bosch heat pump dryers. It is the 4-digit equivalent of error code E:23. The dryer shuts down to protect the inverter and compressor from damage caused by excessive voltage. The first step in diagnosing this fault is checking the mains supply voltage.

No, you should not continue operating the dryer while this fault is active. An overvoltage condition poses a risk of damage to the compressor inverter and compressor motor, and repeated exposure to elevated voltage can cause permanent component failure. Resolve the cause of the fault before resuming normal use.

Repair costs vary depending on the root cause. If the issue is a high mains voltage corrected by an electrician, costs typically fall in the range of $75 to $200 for a service call and any circuit adjustments. If the compressor inverter board needs replacement, parts and labor combined can range from $250 to $600 or more depending on the specific model and local labor rates.

Checking the mains voltage at the outlet is something a knowledgeable DIYer can do with a multimeter. If the voltage is consistently high, contacting your utility provider or an electrician is the appropriate next step. However, if the inverter board itself has failed, replacing it is a more advanced repair that typically requires a qualified appliance technician.

A reset may temporarily clear the fault display, but if the underlying cause, such as elevated mains voltage or a failing inverter board, has not been corrected, the code will return. Clearing the code without addressing the root cause risks further damage to the inverter and compressor. Always diagnose the voltage supply before assuming a reset has resolved the problem.
