We have a double drawer Fisher Paykel dishwasher and one of them seems to
have a problem with the rinse aid.

In the top washer, you can see rinse aid in the dispenser, in the bottom
drawer though the dispenser is full of water (which it shouldn't be).
Normally the level of rinse aid just drops until it needs to be refilled.

Any dishwasher experts or cognoscenti who would like to guess where the
problem lies? I haven't started poking around with a multi meter yet.
