Our dishwasher started to give us the error code for drain issues (auto smart & heavy) and we have since cleaned the filter, drain hose, case break, under-the-sink drain, and replaced the broken vane check, but it still gives us the same error. What else could it be?
When we exchanged the drain pump, we found the missing part of the vane check in the old pump and had high hoped that we found the culprit. We installed the new pump and it still gives us the same error code.
Despite cleaning the filter, drain hose, case break, under-the-sink drain, and replacing the broken vane check, the error code for drain issues persists. This suggests a more complex issue.
Potential causes include a malfunctioning drain pump, a clogged drain passage deep within the dishwasher, or a faulty control board. To resolve the issue, consider contacting a Samsung dishwasher repair technician for further diagnosis and repair.
