Just inherited a Hoover Optima D830 dishwasher. About 8-10 years old, hasn't
been used for last 4 years and little used before that. Still in situ, cold
fill only.
As a trial run I checked the filter on the inlet hose, set the most
intensive programme and pressed the start button. Sounds of water entering
and then the washing process started. Looking good thinks I.
Some while later the waste is pumped out successfully but it does not
refill. The program continues without water and the internal heater is still
live and working! I checked this during the 'Daily' segment of the program.
There was a lot of froth in the machine but I had not put any detergent in.
Started from the beginning again but no water fill.
Turned it off at the mains and tilted it sideways to look for bad
connections, broken wires or anything else obviously amiss. Didn't find
anything. Went through the trial run process again, filled again but not
filling after initial fill/drain.
The water inlet valve appears to be ok. It seems as if something is telling
the machine that it has sufficient water when in fact it has not.
I've googled for some hours without much success but have come across
reference to sticking float switches. Have checked inside the machine but
can see nothing that looks like it might be a float switch.
Tilted the machine again to look for anything that might be a float switch,
no joy.
Tried the trial run again, exactly the same. Filled again but not filling
after initial fill/drain.

After several attempts I have found that if I tilt the machine for a couple
of minutes it will fill at the beginning of a cycle but not again. Always
plenty of white froth.
Unfortunately I don't have any manuals, diagrams or any other paperwork.
Gut feeling is that this is a simple problem but I don't know how to go on.
Any ideas please?

I hope the above makes some sense

Thanks

Nick.
