Why are irregular doses delivered in Brasilia Coffee Maker?
- JJessica MillerSep 13, 2025
If your Brasilia Coffee Maker is delivering irregular doses (dosed version only), there could be a leakage in the infra-red doser, the doser’s rotor might not turn freely, the delivery solenoid valve could be leaking from the discharge, the expansion valves might be leaking during delivery, or the infusor might be operating irregularly. If there is humidity on the outside of the doser or on the diode holder flange, replace the doser. Replace the doser if the rotor doesn’t turn freely. Check and replace the delivery solenoid valve if necessary. Check the calibration and eventually the seal of the expansion valves, being careful not to fully unscrew the expansion valve regulation union with the boiler under pressure. Check and replace the infusor if necessary.
