Someone! used Fairy liquid instead of dishwasher tablet but also on the same day there was a power cut - not sure which caused the malfunction. Now I cannot get the dishwasher re-programmed or even get the machine to power off. Additionally, A rinse -aid warning, a salt warning and a "tap" symbol has appeared. Managed to get the Rinse aid eliminated thus far. Any further suggestions suggestions ?
