Bosch Dishwasher Error Code Er:07

Er:07 means the dishwasher detected an unexpected temperature increase in the wash tub without the control board having activated the heating element. This is treated as a fatal error because uncontrolled heating is a safety concern. The most common hardware causes are a heating element shorted to earth or a heater relay on the control board that is stuck in the closed position. The dishwasher will not resume normal operation until the underlying fault is corrected.

No, you should not attempt to operate the dishwasher while Er:07 is active. The fault indicates a potentially uncontrolled heat source inside the appliance, which poses both a burn and fire risk. The dishwasher is designed to halt operation when this code appears precisely because continued use under these conditions is unsafe. The fault must be diagnosed and repaired before running any cycles.

Repair costs depend on which component has failed. A replacement heating element typically falls in the range of $30 to $80 for the part alone, with labor adding $75 to $150 if a technician is hired. A replacement control board is considerably more expensive, often ranging from $100 to $300 or more for the part, plus labor. Getting a diagnostic assessment first will confirm which component needs replacement and give you a more accurate cost estimate before committing to repairs.

A knowledgeable DIYer comfortable with multimeter testing can perform the initial diagnostic steps, specifically checking the heating element for a short to earth by testing continuity between the element terminals and the chassis ground. If the element is confirmed faulty, replacing it is a moderately involved repair that requires accessing the base of the dishwasher. If the control board relay is the cause, board replacement is more complex and many homeowners prefer to have a technician handle that work.

Er:07 is classified as a fatal error, which means a simple power cycle or reset is unlikely to permanently clear the code. Even if the display clears after a reset, the fault will return as soon as the control detects the same unexpected temperature rise again. The underlying hardware problem, whether a shorted heating element or a stuck relay, must be repaired before the error will stay cleared.
