Bosch Dishwasher Error Code E:0108

E:0108 means the D-Bus power limit was exceeded, causing the internal current limiter to activate and shut down power to the circuit. As a safety response, the dishwasher terminates the current wash cycle and logs the fault. The error indicates that current draw on the internal power distribution bus reached an unsafe level. The power module is the most commonly implicated component when this error appears.

You should not continue running the dishwasher until the cause of E:0108 is identified. The error indicates an overcurrent condition that the appliance's safety system shut down to prevent damage. Running the machine repeatedly in this state risks damage to the control electronics or wiring. A single reset attempt is reasonable, but recurring errors should be diagnosed before further use.

Repair costs depend on the root cause. If only a reset is needed, there is no parts cost. If the power module requires replacement, parts alone can range from roughly $80 to $200 or more depending on the model, with additional labor costs if a technician performs the repair. Wiring harness repairs are generally less expensive than module replacement, though total cost varies with the extent of the damage.

A reset can clear E:0108 if the overcurrent condition was caused by a temporary power surge rather than a hardware failure. To reset, power the dishwasher off at the circuit breaker or unplug it for a few minutes, then restore power. If the error returns during the next cycle, a hardware component such as the power module is likely the cause and should be inspected.

Start by resetting the appliance and running a cycle to see if the error returns. If it recurs, the power module is the primary component to inspect and likely replace, as it directly manages current on the D-Bus. Also inspect the wiring harness and connected components like the pumps and heating element for signs of shorts or damage. Replacing a faulty power module is typically required to permanently resolve a recurring E:0108 fault.
