What RINSE Light Flashing means
On Monogram ZBD9900 top-control dishwashers, including the ZBD9900RII, a flashing RINSE light is a pressure sensor reading that the technician sees in the service test. The sensor's output signal was above 4.8 volts DC, which is outside its normal range, and the program carries on. The owner does not get a message about it. The sensor tells the control how much water is in the tub, so a bad reading can lead to uneven fills. This reading is confirmed for the ZBD9900 series.
Common causes of RINSE Light Flashing
- Pressure sensor and its hose
- Wiring to the pressure sensor
- Main control input for the sensor
1. Let the cycle finish and look at how much water sits in the tub afterward. 2. Clean the filter and the sump area. 3. Check that nothing is blocking the drain at the bottom of the tub. 4. Run another cycle and watch whether the fill looks normal. 5. Call us if the water level looks too low or too high.
- The sensor value is only visible in the service test
- We check the sensor hose for clogs and the wiring for damage
- We compare the sensor reading with the actual water level
Other Dishwasher codes
Will the dishwasher still wash?
Yes, the program continues. But the control may fill with the wrong amount of water if the sensor reading is off, so the wash can vary between loads.
Is this the same as an overfill?
No. HEAVY is the overfill message that the owner can see. This one concerns the sensor signal itself and shows up in the service test.
Do I need to replace the sensor?
Not necessarily. A blocked sensor hose or a loose connector gives the same reading. We test those before recommending any part. Often the repair is just a hose or connector, which keeps the cost down.
Still seeing RINSE Light Flashing?
A technician diagnoses it on site and gives you the price in writing before any work starts.
