Brew Group Failed to Initialize or Complete The Brew Cycle
Possible Faulty Parts:
Fix:
The Brew Group is experiencing difficulties moving due to worn, swollen or broken Piston Gaskets.
Replace Piston gaskets and lubricate Brew Group, or replace the Brew Group.
The Encoder (sits on the Gear Motor) is defective. The Power Board informs the Encoder the brew process has begun, which in turn, dictates the positioning of the Brew Group, via the Gear Motor.
Visually inspect the Encoder and wires to Encoder for damage/corrosion. Replace Encoder.
If the Gear Motor is emitting a low buzzing noises, or sounds like it is struggling during operation, the Gear Motor may not be operating at the full 12V needed.
Replace Gear Motor.
If the Brew Group Gear Motor does not move (machine is clicking instead), then the transformer or PCB is defective. (The transformer increases or decreases the voltage of an alternating current).
Replace transformer. Replace the PCB; however, it is more economical to buy a new or refurbished machine.
