De'Longhi Dedica coffee buttons blinking: temperature too high
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
If both coffee buttons on your De'Longhi Dedica EC680 blink after using the frother, the temperature is too high to brew espresso correctly. Put a container under the frother, turn the steam dial to ON until water stops flowing and turn it back to O.
Safety first
Stop and check this first
- The water coming out of the frother when you turn the dial is very hot: use a container and keep your hand away from the nozzle.
Safe checks you can perform
- Release water through the steam dial
- Turn the dial back to O
- Brew a test espresso

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Release water through the steam dial
- Who:
- you.
- How:
- put a container under the frother and turn the steam dial to the ON position to release water, as De'Longhi instructs.
- Result that matters:
- water flowing and then stopping.
- If water flows:
- the machine is lowering its temperature; wait until it stops.
- If nothing flows:
- turn the dial back to O and prepare the record.
- Evidence to keep:
- a note of whether you had just used steam.

Turn the dial back to O
- Who:
- you.
- How:
- when water stops flowing, turn the dial to the O position.
- Result that matters:
- whether the coffee buttons stop blinking.
- If they stop:
- the machine is ready to brew.
- If they keep blinking:
- repeat once and, if nothing changes, note it.
- Evidence to keep:
- a photo of the panel after the procedure.

Brew a test espresso
- Who:
- you.
- How:
- brew an espresso and watch whether the panel behaves normally.
- Result that matters:
- an espresso brewed with no blinking.
- If it brews well:
- it was the post steam temperature.
- If the blinking returns without having used steam:
- contact De'Longhi service.
- Evidence to keep:
- date and a short video of the blinking if it persists.

What it means
De'Longhi explains that on the Dedica EC680, when both coffee buttons blink after using the frother, the temperature is too high to brew the espresso correctly. After making steam the heater sits above coffee temperature and the machine waits for it to drop. It is not a fault: De'Longhi shows how to lower it by releasing water through the steam dial, after which the machine is ready again.

Evidence: Why are the control panel lights flashing after I used the frother on my Dedica EC680?
- Blinking that does not respond to the procedurePossible
After releasing water and turning the dial back to O the buttons keep blinking; it is no longer the post steam temperature and service is next.
