Flashing lights and a beeper point to a control error. The guide's answer is START/RESET, then a restart.
Model compatibility: Monogram reuses codes across series and model years, so Control Error (flashing display lights) 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
A control error is shown by flashing lights and a beeper; START/RESET silences the beeper and the dishwasher tries to reset.
Lights flashing on the display and a beeper sounding: the use and care guide labels this a control error. It appears in the guide twice, with slightly different wording.
What the guide says to do
Press the START/RESET pad. That turns the beeper off.
The dishwasher then tries to reset itself.
Start the wash cycle again.
If the error keeps coming back, call for service.
The variant with a flashing rinsing light
In the other entry, START/RESET also silences the beeper, but the rinsing light carries on flashing. The instruction there is the same ending: if this continues, call for service.
Models
The Monogram ZBD3500, ZBD3540 and ZBD3900 are the dishwashers in this guide. They belong to an older series.
