When selecting coffee shot the water only reports to overflow 77 at tray. The only way to get water to the diffuser location is by jumping the 93 solenoid with the wires from the 92 solenoid. Is this a power card issue?

If water flows through 93 when connected, it seems to be OK. I would try to measure the voltage on 93 when coffee ist selected. If it remains to zero, the power supply may be bad. Follow the wires. Perhaps a faulty relais, transistor or triac? Good luck!
