Error codeUP
ApplianceCooktop
Quick answer
UP means the input voltage is too high or low. Check the power connection and restart once the voltage is regulated.
Model compatibility: Dacor reuses codes across series and model years, so UP 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
UP means the input voltage is too high or low.
UP means a voltage problem
The UP code says the input voltage reaching the cooktop is too high or too low. It is listed for the Modernist induction cooktops DTI30M977BB and DTI36M977BB.
What the manual says to do
Check the power connection, and make sure to turn the cooktop on only after the voltage is regulated. The range given is 208 V to 240 V. Adjusting household supply belongs to an electrician or technician.
Other codes you might see
F0 is a communication failure inside the cooktop, not a supply message.
If UP keeps returning after the connection is checked, call (310) 742-1907 about Dacor cooktop repair in Los Angeles. Have the code, your model and the connection check you made ready.
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.
