DeLonghi Magnifica Evo Leaking Water? 5 Fixes (ECAM290-298)

Where the Leak Shows Up Points to a Different System Entirely

A leaking Magnifica Evo (ECAM290, ECAM292, ECAM295, ECAM298) usually traces back to one of four places, and each one behaves differently enough that location alone gets you most of the way to a diagnosis: the brew group gasket, the water tank seal, an internal expansion chamber on the machine's left side, or plain drip tray overflow.

This covers water leaks specifically — if you're also seeing icon-based warnings like the wrench or water drop light, those are a separate diagnostic path covered in the dedicated error lights guide, not necessarily connected to an actual leak.

Quick Checks (Under 2 Minutes)

• ✅ Empty the drip tray and grounds bin completely, then dry the area underneath before testing further
• ✅ Check whether the leak appears during brewing specifically, or even when the machine is idle — this narrows down which system is involved
• ✅ Look specifically at the left side of the machine — DeLonghi's ECAM series has a known internal expansion-chamber leak point unique to that side
• ✅ Confirm the water tank clicks fully into place, not just resting against the machine body

Fix 1: Replace or Clean the Brew Group Gasket (Works 30% of Time)

Symptoms: Water or wet grounds appearing around the side door where the brew group sits, most noticeable right after brewing.

How to Fix:

1. Open the side service door and press the release button to remove the brew group
2. Rinse it under warm running water — no soap — to clear coffee oils and grounds
3. Inspect the black rubber gasket around the brew group's edge for cracking, flattening, or a hardened, glazed texture
4. If it looks worn, order a replacement gasket kit for the ECAM290-298 range and swap it following the machine's manual
5. Reinsert the brew group until it clicks fully into place and close the door

Time: 15 minutes (longer if ordering a replacement gasket) Cost: Free to inspect, $10-15 for a replacement gasket Success Rate: 30% Difficulty: Easy

---

Fix 2: Check the Water Tank Seal (Works 24% of Time)

Symptoms: Water pooling under the base specifically near the tank compartment, worse right after refilling.

How to Fix:

1. Remove the water tank completely and check the rubber seal or O-ring where it connects to the machine body
2. Inspect for cracking, misalignment, or debris preventing a clean seal
3. Wipe the seal and its seat, then reseat firmly
4. Fill the tank and place it on a dry towel for a few minutes separate from the machine to rule out a cracked tank body itself
5. Reinsert and run a test brew

Time: 10 minutes Cost: Free–$10 Success Rate: 24% Difficulty: Easy

Fix 3: Address a Left-Side Expansion Chamber Leak (Works 20% of Time)

Symptoms: Water appearing specifically from the left side of the machine, distinct from the tank or brew group areas.

Meaning: DeLonghi's ECAM series routes an internal expansion tube through the left side of the housing, and the fitting there is a documented weak point that loosens or cracks with age and heat cycling — a known pattern across the Magnifica line, not unique to a single unit.

How to Fix:

1. Confirm the leak location matches this pattern by wiping the machine dry and watching where water first reappears during a cycle
2. This fix requires opening the machine housing, which is more involved than the tank or brew group fixes above
3. If you're comfortable with basic disassembly, check and reseat the internal hose fitting at that location, replacing the small O-ring if it looks worn
4. If you're not comfortable opening the housing, this is a reasonable point to move to professional repair rather than continuing DIY

Time: 30-45 minutes (advanced) Cost: Free–$10 for a fitting O-ring, or professional repair cost if outsourced Success Rate: 20% Difficulty: Moderate

---

Fix 4: Rule Out Drip Tray Overflow (Works 16% of Time)

Symptoms: Water appears near the base only after several brews rather than immediately.

How to Fix:

1. Remove the drip tray and grounds bin completely
2. Check the tray's drain channel for grounds or scale blocking it
3. Clean and dry both thoroughly before reinserting
4. Check the tray after every few drinks rather than waiting for the fill indicator

Time: 3 minutes Cost: Free Success Rate: 16% Difficulty: Easy

---

Fix 5: Descale to Clear Pressure-Related Leaks

Symptoms: None of the above fully resolves it, and it's been 2-3 months since the last descale.

Meaning: Scale buildup narrows internal tubing, raising pressure until water finds the weakest seal — often stressing the same gaskets and O-rings covered above rather than causing a wholly separate leak.

How to Fix: Run the Evo's built-in descaling program with DeLonghi EcoDecalk or a citric acid solution, following the on-screen prompts, then retest each fix above if the leak continues.

Time: About 30 minutes Cost: $10-15 (descaler) Success Rate: 10% Difficulty: Easy

Model-Specific Notes

ECAM290/292 (dial interface): Same brew group and tank seal design as the touch-panel models — Fixes 1-4 apply identically.

ECAM295/298 (touch panel, LatteCrema): The added milk system is a separate leak source from the water-side issues covered here — if milk rather than water is the fluid you're seeing, that's a frother-circuit problem, not this guide.

Any Evo model: The left-side expansion chamber issue in Fix 3 has been reported across the whole ECAM290-298 range, not tied to one specific SKU.

When DIY Won't Work

• The leak persists as a steady drip even when the machine is completely idle, after all five fixes
• The left-side expansion chamber fix requires disassembly you're not comfortable doing
• The machine is still under warranty — contact DeLonghi support before opening the housing, since DIY repair inside the case can void coverage

---

Prevent Future Leaks

• Empty the drip tray and grounds bin every few drinks, not just when full
• Descale every 2-3 months in hard-water areas, every 6 weeks if you're in a particularly hard-water region
• Clean the brew group weekly under running water to keep its gasket from drying out and hardening prematurely
• Reseat the water tank firmly every time — a half-seated tank is one of the most commonly missed causes

FAQ

Why is my Magnifica Evo leaking from the left side specifically?

This points to a documented internal expansion-chamber fitting issue in the ECAM series, not a random defect. It requires opening the housing to inspect, so if you're not comfortable with that level of disassembly, this is a good point to call in professional repair.

Is a leak from the brew group area serious?

Usually not — it's typically a worn gasket that's a straightforward, inexpensive swap. It becomes more serious only if left unaddressed long enough that water damages nearby electronics, so it's worth fixing promptly rather than ignoring it.

How do I tell drip tray overflow apart from a real leak?

Empty and dry the tray completely, then run one brew and watch closely. If water reappears immediately in the same spot before the tray could plausibly have filled, it's a genuine leak rather than overflow.

Does descaling actually help with leaks, or just performance?

Both. Scale buildup raises internal pressure by narrowing tubing, and that added pressure is often what pushes water through a seal that would otherwise hold fine. Regular descaling reduces how often pressure-related leaks show up.

Can I fix a leaking Magnifica Evo myself, or do I need a technician?

The brew group gasket, tank seal, and drip tray fixes are all straightforward DIY jobs. The left-side expansion chamber fix requires opening the housing — reasonable for confident DIYers, but a fair point to hand off to a professional if you'd rather not.

Is this the same issue as the Magnifica S leaking?

Not necessarily — the Magnifica S is an older, mechanically different platform. The left-side expansion chamber issue here is specific to the Evo's ECAM290-298 design.
