I suspect that the keypad membrane pad is bad. I would replace that.
You can use the Mastertemp keypad or the Maxetherm keypad.

Welcome to the site.. the mods will no doubt ask you to update your signature. I thought I would get you pointed in a direction.
I have the same heater in the NA version. Hit the StaRite website and download the manual for your heater if you don't have it anymore. There is a troubleshooting flow chart. start there. There are diag codes on the back of the PC board. good luck
