Ed R.,
I think you gave us a bad model number(not listed in tech data lists).
But,if you want to test the pressure switch circuits, this should work :
Disconnect the water level switch harness from the CCU (connector PR6).
Disconnect the air dome hose from the water level switch.
Now,
On the PR6 harness (from the water level switch)
Check for a closed circuit between pin 1 and pin 2 in the connector,(should be and open circuit).
Check for a closed circuit between pin 4 and pin 6 in the connector,(should be a closed circuit).
Attach a hose to the water level switch and blow into it, lightly until you hear a click from the switch,and recheck the circuits.
Re check for a closed circuit in the harness PR6 pin 1 to pin 2(should be an open circuit , still).
Recheck for a closed circuit between pin 4 and pin 6 in the connector,( should be an open circuit, now)
Check for a closed circuit between pin 4 and pin 5 in the connector,( should be a closed circuit).
Check for a closed circuit between pin 4 and pin 3 in the connector,(should be a closed circuit).
If your tests are correct , you'll need to check the airdome hose and pump for clogs, debris, or detergent, calcium build up causing the switch not to reset properly.
If that is all correct, you'll need to repalce the CCU(that is not common for this complaint).
Good Luck,
:) :) :)
