how to fix Fisher and Pykall Model 512NZ Product 91282-A?

When I switch on the light between the rinse and spin lights up and the warm light and the hold light. If you switched it off and then on again the cold light came on. I left the machine off over night and it worked normally again. After 4 washes the same lights appeared until I pushed all sorts of sequences and then it changed to the hold light coming on after it has been switched on and off twice ie instead of the cold light as it was the first time it stopped working. What can I do to fix it?
