GDT655SSJ2SS
Manufactured April 2018
Used daily, sometimes twice daily, for 4+ years
Currently, dishwasher seems it will usually not run circulation pump
In recent weeks or months, dishwasher has been playing a jingle at random times, even though door is closed, and there was not a cycle running or started
Then we started noticing the wash cycles seemed incomplete, as in the dishes were still dirty, and soap had run down the door after dispenser opened, but wasn’t washed away. We would typically just start a new cycle, and it would complete that time, but no longer the case, even after trying circuit breaker flip
I did some testing per the 31-9253 2016 service guide for GDT655SxJ0xx that I found in other posts here, but I am unsure of next step based on what I’m finding…
All buttons appear to function and toggle settings as expected
Service LED on main control board flashes 1x per 3 seconds when unit is idle
All seems OK per consumer error mode. Door latch detection is good. UI software version is apparently 8.17 (817). After 10 seconds of door status, only the Lock LED remains illuminated
Next I went to service mode. Used #2 to operate water valve for fill, then #3 to operate circulation pump a few times, then #1 to operate drain pump for empty.
Confused at this point that all seems OK, so exited error/service mode, tried to run a cycle, during which I listened to it fill, then it just sat there doing nothing for minutes, so I reset. Perhaps was just luck that circulation pump had just functioned during service mode tests.
Back to service mode where I can no longer get the circulation pump to operate after doing a fill. The Start LED lights and stays lit when I hit the Start button, but the circulation pump does not run. Back to #2 for fill, hit Start and the Start LED lights then goes right out, as if it knows it has enough water already, so go to #3 again, but no circulation pump action after hitting Start.
Wondered about fill level so looked inside after fill and it appears to meet the minimum level shown in the service guide. However, screwdriver press against top of float showed that it was NOT floating. Ran multiple drain/fill operations, and fill usually runs for nearly 60 seconds, but stops before float comes up. Not sure if that is normal or not.
Ran drain pump to empty unit. Exited service mode. Manually dumped some water into dishwasher basin, but not quite to normal fill level. Entered service mode, used #2 to fill, which ran less than a minute, and did bring float up to a point where if I press on it with screwdriver, it does go down and I can hear the flood switch click. Despite that higher water level, #3 service test will still NOT operate the circulation pump, so maybe flood switch has no bearing on circulation pump, but rather just ensures water valve closes before overfill.
I’m not sure what this is all telling me, or what I should check or replace now
