IF YOU HAVE CALCIUM BUILDUP on your shower heads, faucets, etc. your issue might be calcium buildup on a hidden sensor too!
Samsung dishwasher wouldn't finish loads.
An ¿overflow sensor? was gunked up but waterpik alone didn't fix it because calcium buildup.
A vinegar soak THEN waterpik fixed the issue.
I hope this helps somebody else save some money and feel like a good handyman
