does anyone no if a hotpoint df22 dishwasher should heat through the rinse cycle,the timer was replaced 3 years ago and seems to be sticking on rinse with heater on.
Yes, if it’s reaching temp; most prob a broken wire in door loom from stat.
The last two i have done have both not quite reached temp. One was a 85c cut-out operating at 50c. The other was a timer connection failing after some but not enough heat. You may have to sit and trace.
