Geschirrspüler Miele G 1022 SCi 3 LEDs blinken

Servus Henry,

bin kein Experte, hab aber gerade einen F14 bei meinem G1142 (ein paar Beiträge vor Deinem) und mich deshalb notgedrungen schlau machen müssen....
Folgendes findet sich zu F12 im amerikanischen Service-Handbuch TECHNICAL INFORMATION G1000 / G2000 Dishwashers auf S. 211:
Viel Erfolg!

1. Check if On-site water supply valve is closed.
a. Open the water supply valve

2. Check if On-site water supply has low water pressure, less than 14.5 psi.

4. Check Water inlet valve for proper operation by performing the following steps:
a. Insure water supply is open and there is access to the valve housing.
b. Select a wash program and start.
c. After the drain step (30 sec.) the water inlet step will begin. Hold you hand around the valve housing. If you feel a mild vibration, then the valve is receiving power. Replace the WPS valve (Y2). If not go to the next step.
d. Remove bottom drip pan and check the electrical connector to the inlet valves mounted on the left plinth for power. If power is available troubleshoot connector and wiring accordingly. If not go to the next step.
e. Check for power coming off the electronic board. If no power, replace the electronic board. If power is present, check wiring from electronic board to electrical connector. Replace and repair as necessary.

• If F12, F13 or F19 is displayed, disconnect the electrical connector from the electronic board and hook up a multi meter set for continuity.
d. While in operation:
• If no pulses are delivered, take a magnet and pass it over the reed switch. If a pulse is delivered, replace the water diverter. If no pulse is delivered, replace the reed switch.
• If pulses are delivered. Connect the electrical connector to the electronic board, clear the fault and operate the appliance. If an F12 is displayed replace the electronic board.
