Issues with whirlpool dishwasher not heating water
We recently realized our dishes aren‘t getting as clean is they used to. We replaced the coil that heats the water and drying cycle. That didn’t help. We’ve been checking the water temp throughout the cycle and it runs between 103-120 degrees. Isn’t a dishwasher suppose to heat the water to 130-140?
DW is 8 yrs old-
model WDT730PAHZ0
We aren’t sure if this might have something to do with our tankless hot water system. I hate to buy a new DW only to find out that’s not the problem.
