Flowmeter Not Reading Output - Steam Series


Slayer recommends that all service be performed by an experienced Slayer Espresso trained technician. 

Known Issue:
Connector boot for the flowmeter may read voltage (indicated by yellow flowmeter light and multimeter test) however pulse count will not be relayed to the circuit board. This is critical for volumetric functionality. Verifying terminal boot connections are firmly connected to flowmeter spades has shown to resolve this issue.

This issue only affects Slayer Steam Series machines while in volumetric mode.

Symptoms:
  1. Programed volumetrics do not register weight (LP) or pulse count (EP).
  2. Recipes continuously dose until manually turned off.
  3. Slow volumetric extractions.
    1. Slow volumetric extractions may also be attributed to installation of incorrect flowmeter. Slayer Steam Series machines feature four (4) magnet impeller flowmeters.
  4. Difficulty programming volumetrics.
Steam LP
  1. WT not registering on display while in volumetric mode.
Steam EP

(Video shows WT not calculating while time continues to climb. Manual actuation is required to turn off volumetric recipe.)


Parts:
