S20B RWW20-A/G – usual; flashing display etc

Hi, just moved house and the previous owner has left me his lovely S20B RWW20-A/G fridge/freezer.

Unfortunately, when turnining it on the front display flashes/clicks quite rapidly. Water dispenses fine, ICE does nothing. Freezer is fine, fridge is fine.

I’ve had a nosey about on the forums and understand it’s an issue with the front PCB (or is likely to be that).

However, my questions are:

1. Will this clicking/flashing affect anything else until it’s sorted?
2. How do I dismantle the front to get to the pcb board?

Thanks for any assistance you can give.

Regards

Dave
