SMEG Dishwasher error lights 4 & 5 on

[tvrjohn]

Hi

DWI16 12C
Tried to reset without any success

When machine is switched on lights 4 and 5 on permanently and after a few seconds intermittent beep sounds continuously

Is this a dreaded possible PCB problem ?

Are there any checks that can confirm PCB faults ?

Assume cost of PCB renders the machine an uneconomical repair

Leds 2&5 on overfill protection
Leds 1&2&5 on no heat
Leds 1&3&5 on not filling
Leds 2&3&5 on not pumping out
Leds 3&5 on Temp sensor o/c or s/c
