Hi Martin,
Most likely the problem is a bad key pad on the control panel.
APP does not ship parts to Canada. The best solution is: if you have any relatives or friends in US to give their address to APP and they will ship it to you.
- The part number for the black control panel is
AP2921061
- The part number for the white control panel is
AP2921062
- The part number for the biscuit control panel is
AP2921063
- Here are the break down diagrams for the Kitchen Aid dishwasher
Model KUDM25SHBL1
Good luck.
Gene.
