Bosch Dishwasher Error Code dr:16

The dr:16 code means the wash pump motor reached an unsafe operating temperature and shut itself off to prevent damage. This is a built-in thermal protection response triggered by motor overload or mechanical binding. The dishwasher will not continue the cycle until the underlying cause is addressed. Running diagnostic test P4 is the recommended first step to confirm the fault condition.

You should not continue running the dishwasher until the cause of dr:16 is identified and resolved. The motor thermal shut-off is a protective function, and repeatedly forcing the appliance to run through this condition can lead to permanent motor failure or, in a worst case, a fire risk from an overheating motor. Diagnose the binding or overload condition first before resuming normal use.

If the fix is simply removing a foreign object from the pump area, the cost may be nothing beyond your time. Professional diagnosis typically runs in the range of $75 to $150 for a service call. If the wash pump motor requires replacement, total repair costs including parts and labor generally fall in the range of $200 to $450 depending on the specific model and local labor rates.

Start by turning off the dishwasher and inspecting the filter, sump, and pump area for any foreign objects that could be jamming the impeller. Clean the filter assembly thoroughly, remove any debris, and allow the motor to cool before restarting. If the code returns after clearing obstructions, run diagnostic test P4 and consider that the motor itself may need to be replaced due to worn bearings or failed windings.

A reset may clear the code temporarily and allow a cycle to start, but if the mechanical cause such as a blocked impeller or failing motor is not corrected, the thermal shut-off will occur again and the code will return. A reset alone is not a fix. Address the root cause first to prevent repeated fault events and potential motor damage.
