Rocker, the flashing light should be flashing a code. The codes are in a sticky in the trade technical enquiries pages.
The NTC is a thermistor. If it’s faulty you should get a single flash, i.e. flash, pause, flash, pause etc (looks to be continuous).
The NTC plugs into the bottom of the bowl, it’s a twist fit and has two blue wires going to it.

Re: whirlpool ADG 4504 D/W

OK, if you’re reading the flashing light properly then it’s misreporting the fault. Common problems were the flowmeter (unplug from the metering tank, clean and tighten connection, plug it back on), pressure switch (black thing on the side of the bowl) and of course the NTC.
Hope this helps.
