Was called out to this dishwasher with a ‘no power’ fault. On inspection found main pcb blown to bits. Traced cause to dispenser leaking rinse aid over reed switch connections and door loom. Cut reed switch plug off & insulated cables, repaired damaged loom & fitted new pcb. On switching on , display lights up all characters but buttons unresponsive. Does anyone know if there is a set up procedure for this pcb? -no paperwork with new one. Have had a look at the small display pcb and there is no apparent damage. Thanks in advance, Wiz.
