The sensing light stays dark at the start of the cycle. The dishwasher still washes, and the guide says to call for service.
Model compatibility: Monogram reuses codes across series and model years, so CLEANSENSOR Error 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
The sensing light does not come on at the start of NORMAL or POTS PANS, so CLEANSENSOR is not working, though the dishwasher keeps running.
You start the NORMAL or POTS PANS cycle and the sensing light never comes on. That is what the use and care guide calls a CLEANSENSOR error.
The guide’s description
If the sensing light fails to light at the beginning of the NORMAL or POTS PANS cycle, the CLEANSENSOR is not working. The guide also notes that this light does not remain lit throughout the cycle.
Does the dishwasher still wash?
Yes. According to the guide the dishwasher continues to work without the CLEANSENSOR. The one instruction in the What To Do column is to call for service.
Models
