A cooktop zone was on while Self Clean was active. Turn it off and restart the cleaning cycle.
Model compatibility: Bosch reuses codes across series and model years, so ERR/toP may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
ERR/toP means the cooktop was switched on during an active Self Clean cycle.
A rule, not a breakdown
Bosch’s freestanding range list, covering electric and gas, shows ERR/toP when the cooktop is switched on in the middle of a Self Clean cycle. Think of it as the range enforcing a limit and not as a failure.
Clearing it
Switch off whichever cooking zone is on.
Start Self Clean over.
No service step is given for this code.
The reason behind it
A very high oven temperature and a locked door are part of Self Clean. Bosch’s entry makes clear that the range refuses cooktop use during the cycle, so pick a time for cleaning when the cooktop is not needed.
Before starting a cleaning cycle
A glance across the range top prevents a restart. See that all cooking zones are off and their indicators are dark, and tell the rest of the household not to use the cooktop until the cycle ends. A zone turned on halfway through produces ERR/toP, and the two steps above put it right.
Safety during the cycle
Even with every zone off, the cooktop and the front of the range may become hot.
Do not leave pans, towels or utensils on the cooktop until the cycle is over and the range has cooled.
This code normally goes away with the steps above. If it appears while every zone is off, call (310) 879-1577. More about our work is on the oven repair page.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
