Why does my espresso machine leak from the filter holder?

Leakage around the filter holder usually means coffee grounds are left on the sealing area, the holder is not locked firmly or the basket has been filled too tightly. The espresso manuals specifically warn that grounds around the boiler outlet can cause leakages.

Check the sealing area

1. Switch off the machine and let it cool before touching the holder.
2. Remove the filter holder and wipe away any grounds from the rim and boiler outlet.
3. Refit the filter holder so it sits firmly and turns fully into position.
4. Use the correct amount of coffee and avoid pressing it too hard.
5. Watch the first part of the next brew for drips around the edge of the holder.

If the leak stops after cleaning and reseating, the holder was probably not sealing correctly.

What the result means

1. If the holder seals properly, continue as normal.
2. If leakage continues, check whether the filter basket or seal area is damaged or misaligned.
3. If water leaks before brewing starts, stop using the appliance.

When to stop using it

Stop using the espresso machine if hot water escapes around the holder, if the holder will not lock securely or if the machine becomes unstable during brewing. Do not tighten the holder beyond normal use or attempt to replace internal parts yourself.

If the issue remains unresolved, or if safe use is uncertain, contact the retailer or store where the product was purchased.

Supplied espresso manuals also note that the coffee should not be pressed too firmly, because this can slow the flow and affect sealing and performance.
