Hi,

I have a Frigidaire Dishwasher 4000 series
model pld4375rfc0.

Two weeks ago the buttons started to malfunction:
the start button wouldn't light up and the increase
for a delay start would go only up to 2 hrs, while
I wanted 4 hours. But one way or the other, it
would run.

This week we woke up an "Er" blinking message.
The dishes were washed but not dried (they were
wet and hot).

Later this week we woke up to the same blinking
"Er" and this time the dishes were dirty - it didn't
even run overnight. So We unplugged it and plugged
it back in. A message "Pr" came up. We opened
the door and closed and the message went away.
We ran a wash but it stopped after about 5min
showing the "Er" message again.

I looked online and people suggested to replace
the switch board. I opened the front door to see
if I could find obvious visual damage, but everything
looked good. I closed it all again and the current
message when I plug it in is "Pf" with "hi temp wash"
and "air dry" lights blinking. When I push a button
the number "44" comes up. Then a few seconds
later the "Er" message comes up again.

It might be that I didn't put something back right
since the door does not latch as it used to. But the
bottom line seems to be this "Er" error.

Any suggestions? Thank you for reading. :)
