Sage BES450 / Sage BES870 — Coffee is not hot enough. A cold portafilter or cup removes heat from a small espresso; on milk drinks, milk that was not heated enough lowers the final temperature. Preserve the exact display, drink and timing, then perform the official check once. Rinse the portafilter and cup with hot water, dry the basket, let the machine reach Ready and heat milk only until the jug becomes hot to touch. Keep hands away from hot water, steam, the grinder and moving brew parts. Switch off and unplug before removing a user-removable part; never open the housing, boiler, pump or grinder.

What the symptom may indicate

What this exact symptom meansA cold portafilter or cup removes heat from a small espresso; on milk drinks, milk that was not heated enough lowers the final temperature.
Keep neighbouring faults separateThis guide is limited to “Coffee is not hot enough”; a leak near electricity, a dry pump, uncontrolled steam or a different display requires its own path.

Checks in the right order

  1. Capture the starting point

    Photograph or note “Coffee is not hot enough”, the selected drink and what happened immediately before it.

  2. Make the machine safe

    Keep hands away from hot water, steam, the grinder and moving brew parts. Switch off and unplug before removing a user-removable part; never open the housing, boiler, pump or grinder.

  3. Follow the manufacturer check

    Rinse the portafilter and cup with hot water, dry the basket, let the machine reach Ready and heat milk only until the jug becomes hot to touch.

  4. Retest once and decide

    If the exact symptom clears, observe one normal drink. If it returns, preserve the evidence and contact authorised support instead of repeating resets or guessing a part.

Stop and get qualified help when

  • Stop immediately for a hot plug, damaged cable, burning smell, smoke, water near electrical parts, uncontrolled steam, a dry-running pump, a part moving under pressure or the exact fault returning after one documented test.

Next step

Repair, replace a part, or arrange a diagnosis?

Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.

Resolve it without buying anything

Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.

Replace only the confirmed part

If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.

This guide does not identify a replacement part. Do not order a generic component from the symptom alone.

Arrange a diagnosis before replacing the appliance

Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
