DeLonghi Dedica Won't Brew? 5 Fixes (EC685, EC695, EC785)

Quick Diagnosis: What Is the Dedica Actually Doing?

A Dedica that won't brew is usually telling you with its lights. De'Longhi's manual for the EC685, EC695 and EC785 has a troubleshooting row, "The appliance does not make any beverage and the lights flash for a few seconds". Its causes are no water in the tank, the tank not pressed down so its valves stay shut, a blocked boiler outlet or a blocked filter. Two other light patterns stop brewing on purpose: the cooling cycle after steaming, and all lights flashing, which means unplug and call De'Longhi.

The Dedica is a manual espresso machine with a thermoblock. It has no grinder and no infuser to remove.

Fix 1: Fill the Tank and Press It Down (Works About 35% of the Time)

The Dedica's water tank has valves in its base that open only when the tank is pressed down. The manual's remedy appears twice in its troubleshooting table: "Press the tank down lightly to open the valves on the bottom."

1. Fill the tank with fresh water.
2. Slide it into place and press it down lightly until it seats.
3. If the lights flash rapidly, that's the manual's signal for "The water tank is empty or the machine does not make coffee". Check the tank again.
4. The manual says: "Never operate the appliance without water in the tank or without the tank."

Fix 2: Clean the Filters and the Spout Holes (Works About 25% of the Time)

For "Espresso coffee is not delivered any more", the manual lists blocked holes in the filter holder spouts, a blocked filter, and "the perforated filter is missing".

1. Filters: rinse after each use, and clear blocked holes with a pin. Give them a full clean at least monthly.
2. Filter holder spouts: clean the spout holes.
3. Coffee spouts / boiler outlet: every 200 coffees, run about 0.5 L of water through with no coffee.
4. Check the perforated filter is in place in the filter holder.
5. None of these parts go in the dishwasher.

Fix 3: Less Coffee, Lighter Press, Right Grind (Works About 18% of the Time)

Two manual rows cover this:

• "The filter holder cannot be attached": too much coffee in the filter. Use the measure supplied, and the right filter for one or two cups.
• "Delivered too slowly" (dark crema): coffee pressed too firmly, too much coffee, coffee too fine or damp, or a blocked filter or boiler outlet. Press less firmly, use less coffee, and use dry pre-ground coffee for espresso machines.

If it runs too fast instead, the manual says to press more firmly, use more coffee, or use pre-ground coffee made for espresso machines. Using ESE pods? Fit the pod filter, centre the pod, and make one coffee at a time with the 1-cup button.

Time: 2 minutes

Success Rate: About 18%

Fix 4: Descale When the Steam Key Flashes Orange (Works About 12% of the Time)

Limescale is the last cause in "not delivered any more", and it also slows delivery. The Dedica tells you when to descale: the orange light on the steam key flashes. The manual says to use De'Longhi descaler only. An unsuitable descaler "may result in faults not covered by the manufacturer's guarantee". Our Dedica descaling guide has the full walkthrough.

1. Remove the filter holder. Put a 1 L container under the hot water dispenser and the boiler outlet.
2. Fill the tank with descaler and water up to MAX.
3. Hold the steam button for 10 seconds until the three buttons flash in sequence.
4. Turn the steam dial to hot water, and press steam to start.
5. Close the steam dial from time to time so descaler also runs through the coffee spouts.
6. When delivery stops, empty the container, rinse the tank, refill it with fresh water and press steam to rinse. The manual runs a second rinse. The orange light goes off when it's done, then close the dial. It takes about 25 minutes in all.

Time: About 25 minutes
Cost: De'Longhi descaler
Success Rate: About 12%

Fix 5: Cooling Cycle After Steam, or All Lights Flashing (Works About 10% of the Time)

Both coffee lights flashing together right after you steamed milk: the boiler is too hot for espresso, and the machine won't brew until it cools. The manual's cooling cycle:

1. Put a container under the frother.
2. Open the steam dial until the coffee lights flash, then close it.
3. When the coffee lights are steady, brew.

All the lights flashing, and the machine doesn't work: "Disconnect the appliance immediately and contact authorised Customer Services." There's no owner fix for this one.

After brewing, the filter stays stuck to the boiler outlet: the manual says to insert the filter holder again, deliver a coffee, then remove the holder.

Time: 2 minutes
Cost: Free
Success Rate: About 10%
Difficulty: Easy

When DIY Won't Work

If none of the manual's causes explain it, or all the lights flash, the Dedica needs De'Longhi Customer Services. The manual describes no owner repair inside the machine. Coffee dripping from the edges of the filter holder, rather than the spouts, can be a worn boiler gasket. The manual sends that to Customer Services too. Our Dedica EC685 guide covers the other faults.

Prevent Future Brewing Failures

• Press the tank down every time you refit it.
• Rinse the filters after each use, and clean them fully each month.
• Run 0.5 L through the spouts every 200 coffees.
• Descale when the orange light flashes, with De'Longhi descaler.
• Run the cooling cycle before an espresso that follows steaming.

FAQ

Why does my Dedica make noise but produce no coffee?

The tank is empty, or its valves haven't opened. Press the tank down lightly. If water is flowing, the filter, the spout holes or the boiler outlet may be blocked, or there's limescale.

Why won't my Dedica brew after I steamed milk?

It's in its cooling cycle: both coffee lights flash together. Open the steam dial over a container until the coffee lights flash, close it, and wait for them to go steady.

What does it mean when all the lights flash on my Dedica?

The manual says to disconnect the appliance immediately and contact authorised Customer Services.

Can I use vinegar to descale my Dedica?

The manual specifies De'Longhi descaler, and warns that unsuitable descalers may cause faults the guarantee doesn't cover.

Which Dedica models does this cover?

It follows the De'Longhi manual for the EC685, EC695 and EC785. Other Dedica versions have their own manuals, so check yours for differences.
