I have Model ADP8332 Diplomat dishwasher. It is almost new and I think I am the first user of it. I did the salt fill process and had one successful wash. After that it starts to run, begins making strang sounds (clicking like a relay, together with a sound like it is unable to turn something) it eventually shuts off, starts beeping, and displays either an F2 or F8 fault. I have received both of these fault codes. But mostly the F8.
F2 and F8 are (sort of) related, they both indicate a water level/overfill problem.
If this has just been installed and the waste hose fits to a spiggot under the sink check that it isn’t back syphoning firstly and that water can get out (the spiggot may be sealed at one end).
