Whirlpool DWFB10 – 8 flashes fault code

Our intergrated Whirlpool/Ikea DWF B10 dishwasher has developed a fault.

Part way through it’s cycle (but not always at the same point) it seems to get stuck, with the wash cycle stopping and starting in short bursts. It then reverts back to the rinse cycle, at the end of which it will make a constant beeping sound with the ‘start’ button light flashing 8 times in a sequence.

This happens most times we use it (much to my annoyance) although we can, most of the time, get the appliance to complete enough of the cycle to ensure the contents are clean.

Most confusingly it sometimes works perfectly through it’s cycle with no issues!!

Also during the latter stages of the wash and final drying stage it produces a rather interesting smell!!

Any help would be appreciated!!??
