jackson 27904 dishwasher

Hi
This dishwasher get stuck on the heat cycles but does heat.
Found 2 stats which are both n/c and tested them in hot water and all seems to be OK.
If the eco button is pressed the machine progresses through the wash heat but then gets stuck on final rinse heat so eco uses the 55 degree stat but final rinse uses the 65 degree stat.
So I think I need a 65 degree stat unless anyone can put me right.
Can anyone supply the part number of this stat or the Hygena equiv.
Glad not many of these around now.

Regards
Dave
