Take a sharpie pen and park the hub on that gear so you get it back on
right (it fits either way) Pinch the hub and pull the gear off. The
actual timing contacts are under there on the gear (that is why you
mark it, so you don't put it back 180 out of time)
If you look at the trace on the outer ring you see a wedge shaped
segment about 1/8" wide. That is what triggers the water. When you
turn the adjuster you are moving the contact finger in and out,
selecting narrower or wider areas on the contact for more or less
water. Clockwise is less water.
BE CAREFUL about bending those contacts. You can screw it up so bad
nothing works. You might be able to clean the one that selects the
water valve. The whole plate was $34 when I got one a month ago but I
see they want $39 now. The whole thing is $49.
You can force a cycle by jumpering the T and H contacts (in the holes
in front) with an insulated piece of wire. Once it gets going pretty
good pull out the jumper.
