Monogram ZDT/ZDP Dishwasher: START Light Blinking After Door Opened

Low risk · DIY check OK

Code: Start Status Indicator Light Flashing
Appliance: Dishwasher
Brand: Monogram
Warranty: 30-day workmanship

What Start Status Indicator Light Flashing means

Monogram ZDT and ZDP touch-control dishwashers, including the ZDT985SPNSS and ZDT800SPFSS, use the START status indicator to tell you the cycle state. A blinking START indicator means the door was opened or the cycle was interrupted. There is no numbered error behind it. You will see the indicator pulse on the control panel, and the dishwasher will sit idle until you press START again.

Common causes of Start Status Indicator Light Flashing

Door opened during the wash
Cycle stopped partway by a power interruption or door movement
Door closing without fully latching
Door switch giving an unsteady signal

✓ One safe check you can try

1. Push the door shut until it latches. 2. Press the START pad once and close the door within 4 seconds. 3. Press START a second time while the cycle is running only if you want to cancel it. 4. If the light blinks again with no one near the door, write down when it happens.

! Why to stop there

A repeat blink with the door shut points to the latch or door switch, which we test with the unit open.
A cycle that stops on its own may also involve the control, so we check how the door signal reaches it.
You get a written price first and a 30-day workmanship warranty on our work.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Start Status Indicator Light FlashingStart Status Indicator Light Flashing questions

Why is the START light blinking?

On these Monogram dishwashers it means the door was opened or the cycle was interrupted. The dishwasher is waiting for you to restart it.

What is the 4 second rule?

Press START once and shut the door within 4 seconds to resume. A second press of START while it runs cancels the cycle instead.

Is it dangerous?

No. It is a status signal. If it keeps repeating with the door closed, we check the latch and door switch.
