I think the OP said they are only affected in one direction, all 3.
Still, I'd look into the relays. I believe the 06 has 2 relays for each pump. 1 fill, 1 empty.
Not likely, but possible that wires got unplugged at the switches. Had that happen to one wire on mine.
Swap relays around to test if they're bad. Look at all connections.
