To check that the amount spray leakage is
appropriate:-
Fill the salt reservoir with water.
• In diagnostics mode, turn on the fill water valve and
the motor drain. Water will flow out of the dispenser
into the tub, as well as out of the water softener
overflow into the tub.
• Observe the flow from the water softener overflow
(beside the Dispenser). There should be a trickle
(25-100 ml per minute). With experience you can
guess what is appropriate. If the trickle is outside
these rates, replace the softener, as the PI is faulty.
To check that there is water in the salt reservoir,
remove the drawer front and observe the level of water
in the tank. (A quick way to check that there is water in
the salt reservoir is to remove the salt bung and test
the water level by placing your finger down through the
opening.)
Detergent or Rinse Aid in the Water Softener
If detergent or rinse aid is poured in to the salt
reservoir it will destroy the water softener. This could
also happen if the salt bung is left off or falls out.
Evidence of this could be white streaks through the
resin.
