Sage BES450 — 2 CUP button flashes. On BES450 this specific flashing button is the cleaning and descaling reminder, not a request to reprogramme shot volume. Preserve the exact display, drink and timing, then perform the official check once. Start the BES450 clean-and-descale cycle and follow every step on page 17 with the specified product and fresh-water rinses; do not interrupt power. 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.

Safety first
- 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
Checks in the right order
- Capture the starting point
Photograph or note “2 CUP button flashes”, the selected drink and what happened immediately before it.
- 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.
- Follow the manufacturer check
Start the BES450 clean-and-descale cycle and follow every step on page 17 with the specified product and fresh-water rinses; do not interrupt power.
- 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.
