Hello, our house was built in 2017 and the dishwasher has started to have issues with not filling or draining properly. I initially thought it was the fault of the unit and replaced a part on it but think the issue is related to the plumbing possibly. I am no plumber, but shouldn't the drain be routed up high under the counter before it goes into the Johnson tee? Would it be better to connect the drain directly to the disposal instead? Thanks for any help.
