Customers Complaint - glasses & cutlery have a cloudy white film on them and/or plates have a
Cause of problem.
How to resolve the
problem.
white chalky film on them
Hard water and not enough detergent being used. Minerals from the
water are building up on the dishes or the water softener is not set to
the correct water hardness level, or is faulty.
Once this film forms on the dishes it cannot be removed by normal
running in the dishwasher. The dishes will need to be cleaned by
soaking them in an acidic solution (such as white vinegar and water).
Where a Water Softener is not fitted in the product:
To prevent the build up re-occurring, the customer will need to fill both
the main-wash and pre-wash detergent cups to the top with a power
detergent, and we would recommend running on normal cycles, not
Eco. There are detergents available to be used with hard water that have
a softening agent built in, these powders will work up to moderately
hard water.
In problem areas with very hard water, the customer may need to
use a detergent additive designed for use in hard water areas, or fit a
household water softener to the incoming water supply.
Where a Water Softener is fitted:
Set the water softener for the correct local water supply hardness.
Check that the water softener is functioning correctly in diagnostics.
C1 Water Softener Diverter Valve
In hardware output diagnostics test mode:
FU – turn the fill water valve on
P2 – turn the motor drain on
C1 – water softener diverter valve
On – water bypasses the resin tank
Off – water flows through the resin tank
C2 Water Softener Brine Pump
Turn the brine pump on in diagnostics mode. Observe a small quantity
of water (approx. 30 ml per min.) flowing out the bottom of the
dispenser (drop the dispenser door down to observe this.) Observe a
change in the water level (approximately 120ml per 4 min.) in the salt
reservoir. The reservoir should pump dry of water in this time.
Note: - Fill the salt reservoir with salt (and then water if not already)
before performing this test.
