So I have a GE GDT655SMJ5ES.
Recently, the dishwasher has an issue with the control board. SOMETIMES it doesn't shut off, so every hour (or 2?) it makes a beep sound that it thinks it's still open (unless it's running, then it's quiet).
Now, I'm wondering if that ^ issue is related to a dirty top rack problem I have.
I can't say whether it popped up at the same time as the control board, it could be. I know that we've lived here for 2+ years and didn't have the issue before, and our habits (for as far as we can recall) have not changed.
Problem:
The top rack has residue left over in the bowls. Photo of minimal example (some bowls are full of this): https://imgur.com/a/9s1SCtq
We use Walmart powdered detergent, doesn't matter if we use more or less. Same issue. We fill up both the basket and the pre-wash basket.
What I've tried & done:
- Clean the filter (we do it weekly)
- Clean the metal filter (also weekly)
- Cleaned out the arms, they were clean. Attached hose, all flow at the same rate.
- Inspected and cleaned the plastic bit at the back that makes the water travel to the top sprayer, was clean.
- Ensure that nothing stops the arms from spinning.
- Run it empty.
- Run it with vinegar.
- Run it on a long cycle with cleaning tablet.
- Ran it with boiling hot water, no difference.
- Ran it with auto-sense dirt or heavy dirt, no difference.
Nothing helped.
If it is the control board, I'm probably getting a high-end Bosh. No point in repairing this, due to age.
Could it be that the ball-valve that directs water to the top is broken? Sometimes I have the feeling that I hear it spin 3 times and then it gives up? I don't know...
