Hi Mike,
the only problem i have seen with this appliance is corruption of the processor , the display then just lights up every didgit, remove the top and on the display panel if you are lucky you wil see a reset switch if you are not its just two shorting links to reset the prosessor , failing that its the pcb.
Just for info as well was repairing tricity bendix dishwasher in garage and hoover had been out the day before and replaced a drain pump with melted windings and main board on AL130 (parts left in garage). May or may not be connected to your fault.
