thanks for the responses.
The machine fills fine, empties fine and heats the water fine. What I have
noticed though is after the machine heats the water to the right
temperature, the heater goes off (which is correct) but then the machine is
still washing the clothes in the same hot water an hour later. I tested
this
using a 90 degree wash on the right hand side of the timer. The heater
doesn't come back on once it goes off but the washing cycle just carries
on.
It's still washing the clothers in the same hot water as I write. So my
question(s) is:
1) do you think it's the controller?
2) should the heater go on and off a few times or just the once?
thanks for any further pointers.


Is it actually reaching the target temperature? Often on hot washes the
program waits in a holding state until the temperature is reached. It
could indicate a failing heater or temperature sensor...


If the temp sensor fails, either the water will boil, or it'll wash
for the usual time or less, and below temp.


Note if the heater has an over temp cutout...

If the heater were failing, the water would heat up faster, or not at
all.

My money's on the controller.


Yup, they do get stuck sometimes... tis what killed our last dishwasher
in the end.
