Bosch Dishwasher Error Code Overheating

The overheating error on a Bosch dishwasher indicates that the heating element is receiving voltage when it should not be, causing water temperatures to rise beyond safe operating limits. This is indicated on the WFL 2060 by a pattern of flashing lights on the control panel. The underlying cause is a faulty control module that has lost the ability to properly switch off the heater circuit. The dishwasher should not be operated until this is diagnosed and repaired.

No, it is not safe to continue running the dishwasher with this error present. A heater that remains on continuously can warp plastic components inside the tub, damage seals, and create a potential fire or burn hazard. Disconnect power to the appliance and leave it off until the control module is inspected and repaired.

Repair costs depend primarily on whether the control module needs to be replaced. Control module parts typically range from $80 to $250 depending on the specific model, with professional labor adding another $75 to $150 in most cases. If the fault turns out to be a wiring issue rather than a failed module, the repair cost can be significantly lower. Getting a diagnostic assessment before ordering parts is recommended.

Start by checking whether voltage is present at the heater terminals during a cycle phase when the heater should be inactive. If voltage is confirmed at that point, the control module needs to be replaced. Before replacing the module, also inspect the wiring harness between the module and heater for any shorts or damaged insulation. Replacing the control module is the most likely fix for this specific fault.

A power reset may temporarily clear the flashing light indication, but it will not fix the underlying electrical fault in the control module. If the module is genuinely faulty and keeping the heater energized, the overheating condition will return once the dishwasher runs again. A reset should only be used as part of diagnostic testing, not as a repair solution.
